STRUHS Commissioner Mr, David McIntyre, Acting Branch Chief RE: MANSFIELD, BWSC/SMP 4-0571 Site Evaluation & Response (HER) Former Hatheway & Patterson United States Environmental Protection Agency REQUEST FOR EPA ASSISTANCE JFK Federal Building Boston, Massachusetts 02203-2211 Dear Mr. McIntyre: The Massachusetts Department of Environmental Protection, Bureau of Waste Site Cleanup (the Department) is requesting the Environmental Protection Agency's (EPA's) assistance at the Former Hatheway & Patterson site located on County Road in Mansfield, Massachusetts. To date, the Department and EPA have conducted response actions at the site consisting of the removal of wood preserving chemicals from bulk storage containers, sampling activities to define the extent of soil and groundwater contamination, and the covering of highly contaminated areas with geotextile fabric and gravel to limit the accessibility of the soil in these areas. On June 11, 1998 the Department tasked one of its contractors to collect surface water, soil, and sediment samples at the site and to have the samples analyzed for dioxins and furans by EPA Method 1613A. The results of the analyses indicate that dioxins are present in all media sampled at concentrations which may constitute an imminent and substantial endangerment to public health and/or the environment. Based on these conditions, the Department is requesting that your office consider conducting a time critical removal action to reduce the level of risk posed to the surrounding community. 20 Riverside Drive • Lakeville, Massachusetts 02347 • FAX (508) 947-6557 • Telephone (508) 946-2700 Lev, Printed an Recycled Paper 2 Attached is the sample data which shows that dioxins (as 2,3,7,8-TCDD equivalent) are present in a surface water sample collected from the Rumford River at a concentration of 40 pg/L which exceeds the fresh water acute ambient water quality criteria concentration of 10 pg/L. In addition, elevated concentrations of dioxins were also detected in sediment samples collected from the river and from the adjacent wetland. The Rumford River flows into Fulton Pond and Cabot Pond which are managed as catchable trout ponds which are annually stocked with trout by the Massachusetts Division of Fisheries and Wildlife (MDFW). The Department has requested that the MDFW postpone the scheduled October 1998 stocking of these ponds until additional evaluation can be conducted. The Rumford River and associated wetlands continue to be impacted by light non -aqueous phase (LNAPL) product leaching into the river and wetland sediments from the site in at least two locations. A sample of this product, which was collected from a monitoring well adjacent to one of these break-out points was also found to contain very high concentrations of dioxins. The Department is requesting the EPA's assistance in this matter because the site is abandoned, the property owner is a trust with no other assets and is financially unable to conduct this work. In addition, considering staff and funding resources available to the Department at this time, it is the Department's opinion that EPA will be able to conduct a time critical response action at this site in a more timely manner. The Department is aware that the EPA is currently conducting a Remedial Site Investigation at this site pursuant to CERCLA, and in support of this effort, the Department will provide the EPA with any new information as it becomes available which can be incorporated into this site investigation when the site is rescored. The Department currently has site access and will provide any additional assistance it can to support the EPA in their removal efforts. Thank you for your consideration in this matter. We look forward to your response. If you have any questions regarding this please feel free to contact me at (508)946-2799 or Scott Sayers at the letterhead address or at (508) 946-2780.

Inc. Case Narrative Data Flags June 22, 1998 45986A In order to assist with data interpretation, data qualifier flags are used on the final reports. Please note that all data qualifier flags are subjective and are applied as consistently as possible. Each flag has been reviewed by two independent Chemists and the impact of the data qualifier flag on the quality of the data discussed above. The most commonly used flags are: A `B' flag is used to indicate that an analyte has been detected in the laboratory method blank as well as in an associated field sample. The B' flag is used only when the concentration of analyte found in the sample is less than 20 times that found in the associated blank. This flag denotes possible contribution of background laboratory contamination to the concentration or amount of that analyte detected in the field sample. An `E' flag is used to indicate a concentration based on an analyte to internal standard ratio which exceeds the range of the calibration curve. Values which are outside the calibration curve are estimates only. An `I' flag is used to indicate labeled standards have been interfered with on the GC column by coeluting, interferent peaks. The interference may have caused the standard's area to be overestimated. All quantitations relative to this standard, therefore, may be underestimated. A `J' flag is used to indicate a concentration based on an analyte to internal standard ratio which is below the calibration curve. Values which are outside the calibration curve are estimates only. A `PR' flag is used to indicate that a GC peak is poorly resolved. This resolution problem may be seen as two closely eluting peaks without a reasonable valley between the peak tops, overly broad peaks, or peaks whose shapes vary greatly from a normal distribution. The concentrations or amounts reported for such peaks are most likely overestimated. A `Q' flag is used to indicate the presence of QC ion instabilities caused by quantitative interferences. An `RO' flag is used to indicate that a labeled standard has an ion abundance ratio that is outside of the acceptable QC limits, most likely due to a coeluting interference. This may have caused the percent recovery of the standard to be overestimated. All quantitations versus this standard, therefore, may be underestimated. An IS' flag indicates that the response of a specific PCDD/PCDF isomer has exceeded the normal dynamic range of the mass spectrometer detection system. The corresponding signal is saturated and the reported analyte concentration is a `minimum estimate'. When the `S' qualifier is used in the reporting of `totals', there is saturation of one (not Triangle Laboratories. Inc. June 22, 1998 Case Narrative 45986A necessarily from a specific isomer) or more saturated signals for a given class of compounds. Results for saturated analytes are reported as greater than the upper calibration limit. A `U' flag is used to indicate that a specific isomer cannot be resolved from a large, co - eluting interferent GC peak. The specific isomer is reported as not detected as a valid concentration cannot be determined. The calculated detection limit, therefore, should be considered an underestimated value. A `V' flag is used to indicate that, although the percent recovery of a labeled standard may be below a specific QC limit, the signal-to-noise ratio of the peak is greater than ten -to - one. The standard is considered reliably quantifiable. All quantitations derived from the standard are considered valid as well. An `X' flag is used to indicate that a polychlorodibenzofuran (PCDF) peak has eluted at the same time as the associated diphenyl ether (DPE) and that the DPE peak intensity is at least ten percent of the total PCDF peak intensity. Total PCDF values are flagged `X' if the total DPE contribution to the total PCDF value is greater than ten percent. All PCDF peaks that are significantly influenced by the presence of DPE peaks are either reported as "estimated maximum possible concentration (EMPC) values without regard to the isotopic abundance ratio, or are included in the detection limit value depending on the analytical method.

These samples were analyzed for dioxins and furans by EPA Method 1613A. The results of the analyses indicate that dioxins are present in the surface water and sediment at concentrations which may constitute a threat to public health and/or the environment. Attached is the sample data which shows that dioxins (as 2,3,7,8-TCDD equivalent) are present in the surface water sample collected from the Rumford River at a concentration of 40 pg/L which exceeds the fresh water acute ambient water quality criteria concentration of 10 pg/L. In addition, elevated concentrations of dioxins were also detected in sediment samples collected from the river and from the adjacent wetland. The Rumford River and associated wetlands continue to be impacted by light non - aqueous phase (LNAPL) product leaching into the river and wetland sediments from the site in at least two locations. A sample of this product, which was collected from a monitoring well adjacent to one of these break-out points was also found to contain very high concentrations of dioxins. A worst case risk screening calculation performed on the surface water sample results indicates that consumption of fish from the Rumford River is likely to present a substantial risk to human health due to the levels of dioxins present. 20 Riverside Drive • Lakeville, N[assachusetls 02347 • FAX (508) 947-6557 • Telephone (508) 946-2700 Zi Printed on Recycled Paper As you are aware, the Rumford River flows into Fulton Pond and Cabot Pond which are managed by the Massachusetts Division of Fisheries and Wildlife (MDFW) as catchable trout ponds. You informed me during out telephone conversation of September 17, 1998 that these ponds are annually stocked with trout during October. Based on the conditions outlined above, the Department requests that your office consider postponing the scheduled October 1998 stocking of these ponds until additional evaluation can be conducted. To accomplish this additional evaluation, the Department has requested that the EPA conduct a time critical removal action at this site to reduce the level of risk posed to the surrounding community.

Case Narrative June 22, 1998 15986A E I I I I I I Data Flags In order to assist with data interpretation, data qualifier flags are used on the final reports. Please note that all data qualifier flags are subjective and are applied as consistently as possible. Each flag has been reviewed by two independent Chernists and the impact of the data qualifier flag on the quality of the data discussed above. The most commonly used flags are: A `B' flag is used to indicate that an analyte has been detected in the laboratory method blank as well as in an associated field sample. T'ne `B' flag is used oniv when the concentration of analyte found in the sample is less than 20 times that found in the associated blank. This flag denotes possible contribution of background laboratory contamination to the concentration or amount of that analvre detected in :he field sample. An 'E' flag is used to indicate a concentration based on an analyte to internal standard ratio which exceeds the range of the calibration curve. Values which are outside the calibration curve are estimates only. ,An 'I' flag is used to indicate labeled standards have been interfered with on the GC column by coeluting, interferem peaks. The interference may have caused the standard's area to be overestimated_ Ail quantitations relative to this standard, therefore, may be underestimated. A 'J' rlag is used to indicate a concentration based on an analyte to internal standard ratio which is below the calibration curve. Values which are outside the calibration curve are estimates only. A 'PR' flag is used to indicate that a GC peak is poorly resolved. This resolution problem may be seen as two closely eluting peaks without a reasonable valley between the peak tops, overly broad peaks, or peaks whose shapes vary greatly from a normal distribution. The concentrations or amounts reported for such peaks are most likely overestimated. A 'Q' flag is used to indicate the presence of QC ion instabilities caused by quantitative interferences. An `RO' flag is used to indicate that a labeled standard has an ion abundance ratio chat is outside of the acceptable QC limits, most likely due to a coeiuting interference. This may have caused the percent recovery of the standard to be overestimated. Aa quantitadons versus this standard, therefore, may be underestimated. An 'S' flag indicates that the response of a specific PCDDlPCDF isomer as exceeded the normal dvnamic range of the mass spectrometer detection system. The corresponding signal is saturated and the reported analvte concentration is a 'minimum _stimate'. When the `S' qualifier is used in the reporting of `totals', there is saturation of one i not Triangle Laboratories. Inc. June 22, 1998 Case Narrative 45986A necessarily from a specific isomer) or more saturated signals for a given class of compounds. Results for saturated analytes are reported as greater than the upper calibration limit. A `L' flag is used to indicate that a specific isomer cannot be resolved from a large, co - eluting interferent GC peak. The specific isomer is reported as not detected as a valid concentration cannot be determined. The calculated detection limit. therefore. should be considered an underestimated value. A `ti' flag is used to indicate that, although the percent recover-., of a labeled standard may be below a specific QC limit. the signal-to-noise ratio of the peak is greater alian ten -to - one. The standard is considered redabiv quantifiable. All quandiadons derived from the standard are considered valid as well. An 'Y' flag is used to indicate that a polychlorodibenzofuran (PCDF) peak has eluted at the same time as the associated diphenvi ether (DPE) and that :he DPE peak intensity is at least ten percent of the total PCDF peak intensity. Total PCDF values are agged 'Y' if the total DPE contribution to the total PCDF value is treater -pan ten percent. All PCDF peaks that are significandy inTluenced by the presence of DPE peaks are either reported as ''estimated maximum possible concentration (EMPQ values without regard to the isotopic abundance ratio, or are included in the detection limit value decending on <<ne analytical method. 0 TLI Project: 45986Cr2 1613A PCDD/PCDF Analysis (c) Client Sample: Break Out Area Analysis File: T983594 Client Project: Hatheway & Patterson Sample Matrix: SOLID Date Received: 06/13/98 Spike File: SP162V2S ' TLI ID: 210-85-6A Date Extracted: 07/15/98 ICal: TF5706V Date Analyzed: 07/20/98 ConCal: TV83585 Samole Size: 1.027 g Dilution Factor: n/a % Moisture: 73.2 Dry Weight: 0.275 a Blank File: T983591 % Lipid: n/a CC Column: DB-5 Analyst: WK '7o Solids: 26.8 Arraiyfis.

The Rumford River system downstream from this site includes Fulton, Kingman, and Cabot ponds, and the Norton Reservoir. Dioxin compounds were detected in water samples and in other media. MDEP and the Division of Fisheries and Wildlife (DFW) have asked MDPH to consider issuing a provisional fish consumption advisory for the following reasons; 1) Dioxin compounds have a high potential for bioconcentration in fish. 2) It is not feasible to obtain fish sampling data in a timely way because of the limited availability of laboratory resources nationwide for these analytes and the technical requirements involved in the analysis. MDPH has issued the following Provisional Public Health Fish Consumption Advisory; RECOMA'lENDATION All persons should refrain from consuming any fish caught in the Rumford 1?iver, Fulton Pond, Kingman Pond, Cabot Pond, or the Norton Reservoir until such time that fish testing results become available.

MULLIGAN commiss1UNER SEPTEMHER 1994 FOR IMMEDIATE RELEASE Contact: Sean Fitzpatrick (617) 624-5200 Phil"^ ITXAL i TN7'F'f3xkl FRESHWATEFFi;i}i QMS .TION ADVISORY The Massachusetts Department'of PUUblic Health today announced it is initiating an education and outreach program to alert the state's medical community about health concerns relating to the consumption of some fresh water fish by pregnant women. while the Department of public health adviser, pregnant women not to consume certain fish caught in .freshwater bodies, it recommends that pregnant women consult their physicians concerning their specific circumstances. The Massachusetts Department of Public Health (MDPHI has reviewed limited fish tissue data collected by One Department Of Mpvironmental Protection taken from freshwater bodies t_broughout the state. Because of potential health Concerns associated with exposure of the developing fetus to mercury, the MDPH offers the following recommendation: REC0MMEAH)AT10N Pregnant women should be advised of the possible health risk from eating fish from Massachusetts freshwatar bodies in order to prevent exposure of developing fetuses to mercury. This advisory does not apply to fish stocked in freshwater bodies by the State Division of Fisheries and wildlife and does not apply to farm raised freshwater fish sold 0006 10/19/98 MON 15:35 FAX 6176245757 MDPH BEHA 2007 ` commercially. At this time, the general public is not considered to be at risk from fish consumption. This recommendation is considered a precautionary measure which should be taken until such time as additional data can be analyzed. Studies are being undertaken by the state Departments of Public Health and Environmental Protection (L)LP) to determine the best combination of advisory, regulatory and/or enforcement initiatives necessary to protect human health and improve nutritional status. The MOPB studies will focus on the possible effects of eating freshwater fish that may be contaminated with mercury on other special populations such as women of childbearing age, children, and infants who are breast fed. DEP will conduct additional monitoring studies to aid in assessing representative mercury levels in freshwater fish throughout Massachusetts, There are over 4,700 water bodies in Massachusetts, To date, fish have been tested from 73 of the st:ate's streams, rivers, lakes and ponds. in come, smaller tish were found,to contain negligible levels of mercury, while some large, predatory species such as bass and pickerel contained levels that may be of concern to developing fetuses according to recent scientific studies. Based on this toxicological analysis of, the Fish from this sample of water bodies, it has been determined that -mercury levels in some fresh water fish pose a possible health concern to pregnant women. in light of this evidence, albeit limited, MDPH has chosen the conservative approach of issuing this advisory. While precautions are urged for pregnant women. the Department of public Health continues to recognize the substantial benefits of fish consumption by the general population. Fish are one of the best sources of natural fatty acids which are helpful in reducing the risk of heart disease. Fish are low in 'saturated fat and high in protein. A varied diet, including fish in lieu of high fat food, will lead to improved nutrition and better health. 2 10/19/98 NON 15:36 FAX 6176245757 AIDPH BEHA 10008 Freshwater Fish Consumption Advisory List Massachusetts Department of Public Health Bureau of Environmental Health Assessment (617) 624-5757 February 1 gge Ballarxivale Impoundmentof Shmsheen River Andover P1-LMB & EC.

KOH, M.D., MPH COMMISSIONER October 19. 1998 Scott Leite, Agent Mansfield Board of Health 50 West Street Mansfield, MA 02048 Dear Mr. Leite: Enclosed please find a copy of a Provisional Public Health Fish Consumption Advisory that is being issued effective immediately for the Rumford River slid associated impoundments, i.e. Fulton, Kingman and Cabot ponds, and the Norton Reservoir. When the Massachusetts Department of Public Health (MDPH) issues its Public Health Fish Consumption Advisories; its usual policy is to first obtain fish tissue sampling data for the water body of concern. Fish tissue sampling data are not currently available for these water bodies in Mansfield. However, the Massachusetts Department of Environmental Protection (MDEP) and Division of Fisheries and Wildlife (DPW) asked MDPH to consider issuing a provisional fish consumption advisory for the following reasons. i) Dioxin compounds have been identified in surface water and near the former Hathe Way and Patterson sites in Mansfield. Dioxin compounds have a high potential for bioconeentration in fish. 2) It is not feasible to obtain fish tissue sampling data in a timely way because of the limited availability of laboratory resources nationwide for these analytes and the technical requirements involved in the analysis. In this particular case, MDPH believes it would be a proactive and prudent public health nrea�ure to issue a provisional advisory without waiting for results of fish tissue sampling. We have asked the MDEP to pursue arrangements with the US. Environmental Protection Agency (USEPA) to obtain fish tissue sampling. We have been informed by DEP that staff from those agencies as well as DFW are working together to develop a fish sampling protocol for 10/19/98 1ION 17:06 FAX 61762.15757 %IDPH BEHA (r3J 0tt5 these water bodies, and DPH has requested the opportunity to review and comment on the protocol. We would appreciate it if you could arrange to post this important provisional advisory information at the town offices and at the water bodies themselves. We have attached a representative poster and will be happy to provide you with any assistance you may need in accomplishing local notification. We would be interested in translating the provisional advisory and posting into any languages you feel are relevant to these water bodies based on the types of populations that you may know of that use this resource, For questions or concerns regarding posting or health education and outreach activities., we can be reached at (617) 624-5757 for follow-up assistance. You should know that you will soon be receiving an updated Froshwater Fish Consumption Advisory List, as we have recently received new fish testing data from MDEP that is currently under review.

O'LEARY SECRETARY HOWARD K. KOH, MD, MPH COMMISSIONER Dear Angler: Please find enclosed the Massachusetts Freshwater Fish Consumption Advisory List, a fact sheet on mercury in freshwater fish, and a copy of the current state-wide advisory on mercury in freshwater fish. The list contains the names and status of water bodies for which freshwater fish consumption advisories have been issued in Massachusetts. Generating an advisory involves the cooperative efforts of the Departments of Public Health (MDPH), Fisheries and Wildlife, and Environmental Protection. These agencies' activities include designing fish surveys and analyzing contaminant concentrations in fish samples. Data generated from the monitoring activities are evaluated, and if significant levels of a contaminant are detected, a Public Health Fish Consumption Advisory is issued. The advisory may suggest either limiting or refraining from consumption of fish from a particular water body. In September 1994, the MDPH issued an advisory informing pregnant women about the possible health risks to the developing fetus from mercury in certain freshwater fish. The fish consumption advisory list contains the status of each water body for which an advisory has been issued. If a water body is not on the list, it may be because either an advisory was not warranted or the water body has not been sampled. Please note that we periodically update the list. If you have any questions or concerns about the advisories, please call Mike Beattie at (617) 624-5757 for follow-up assistance. Sincerely, Elaine T. Krueger, M.P.H.

WELD GOVERNOR ARGEO PAUL CELLUCCI LIEUTENANT GOVERNOR GERALD WHITSURN SECRETARY DAVID H. MULLIGAN COMMISSIONER SEPTEMBER 1994 FOR IMMEDIATE RELEASE Contact: Sean Fitzpatrick (617) 624-5200 PUBLIC HEALTH INTERIM FRESHWATER FISH CONSUMPTION ADVISORY The Massachusetts Department of Public Health today announced it is initiating an education and outreach program to alert the state's medical community about health concerns relating to the consumption of some fresh water fish by pregnant women. While the Department of Public Health advises pregnant women not to consume certain fish caught in freshwater bodies, it recommends that pregnant women consult their physicians concerning their specific circumstances. The Massachusetts Department of Public Health (MDPH) has reviewed limited fish tissue data collected by the Department of Environmental Protection taken from freshwater bodies throughout the state. Because of potential health concerns associated with exposure of the developing fetus to mercury, the MDPH offers the following recommendation: RECOMMENDATION Pregnant women should be advised of the possible health risk from eating fish from Massachusetts freshwater bodies in order to prevent exposure of developing fetuses to mercury. This advisory does not apply to fish stocked in freshwater bodies by the State Division of Fisheries and Wildlife and does not apply to farm raised freshwater fish sold commercially. At this time, the general public is not considered to be at risk from fish consumption. This recommendation is considered a precautionary measure which should be taken until such time as additional data can be analyzed. Studies are being undertaken by the State Departments of Public Health and Environmental Protection (DEP) to determine the best combination of advisory, regulatory and/or enforcement initiatives necessary to protect human health and improve nutritional status. The MDPH studies will focus on the possible effects of eating freshwater fish that may be contaminated with mercury on other special populations such as women of childbearing age, children, and infants who are breast fed. DEP will conduct additional monitoring studies to aid in assessing representative mercury levels in freshwater fish throughout Massachusetts. There are over 4,700 water bodies in Massachusetts. To date, fish have beer, tested from 73 of the state's streams, rivers, lakes and ponds. In some, smaller fish were found to contain negligible levels of mercury, while some large, .predatory species such as bass and pickerel contained levels that may be of concern to developing fetuses according to recent scientific studies. Based on this toxicological analysis of the fish from this sample of water bodies, it has been determined that mercury levels in some fresh water fish pose a possible health concern to pregnant women. In light of this evidence, albeit limited, MDPH has chosen the conservative approach of issuing this advisory. While precautions are urged for pregnant women, the Department of Public Health continues to recognize the substantial benefits of fish consumption by the general population. Fish are one of the best sources of natural fatty acids which are helpful in reducing the risk of heart disease. Fish are low in saturated fat and high in protein. A varied diet, including fish in lieu of high fat food, will lead to improved nutrition and better health.

The advisory was issued in October 1998, when it was first suspected that the fish in these water bodies may be contaminated with pesticides and dioxins. Study has been on going, but conclusions may not be available prior to the May 81h fishing derby. The Massachusetts Department of Public Health, Bureau of Environmental Health Assessment has recommended the following: 1. Be aware of the Provisional Public Health Advisory (printed on reverse side) 2. Catch and release all fish. Do not eat any fish. 3. As an extra precaution, wash hands thoroughly after derby. There is no danger handling fish contaminated with pesticide or dioxin, it is an internal contaminant, requiring ingestion over a period of time to be harmful to humans. Hand washing thoroughly is simply a good idea. If you have any questions, please feel free to contact me at 508-261-7366. Yours truly, Ma;Board of Health Sco, Health Agent PROVISIONAL PUBLIC HEALTH ADVISORY RUMFORD RIVER; FULTON, KINGMAN, & CABOT PONDS NORTON RESERVOIR CONTAMINANT RELEASE Former Hatheway & Patterson site in Mansfield Possible pesticides and dioxins DO NOT EAT FISH CATCH & RELEASE For more information, contact: Massachusetts Department of Public Health: 617-624-5757 October, 1998 Scott Leite From: stephen spilewski [ssryaniron@hotmail.com] Sent: Wednesday, October 24, 2001 11:50 AM To: superfund.docket@epa.gov; janowski.chet@epa.gov; harting-barrat.pamela@epa.gov; scott.sayers@state.ma.us; sleite@mansfieldma.com; dlewis@mansfieldma.com Subject: hatheway & patterson npl site October 24,2001 Attn: Docket Coordinator,Headquarters U.S. EPA CERCLA Docket Office 1200 pennsylvania Ave. Washington, DC. Re: Hatheway & Patterson Site (EPA ID #MAD001006805) Mansfield, Ma. To whom it may concern, The following are my comments and concerns regarding the above -mentioned project as a proposed Superfund clean-up site: My property, 42 Howe Street Mansfield, Ma. abutts the southerly portion of the Hateway & Patterson (H&P)site for approx. 270 feet. From the former Foundry st. to the Rumford river backwash channel. Along this border, the land is an "artifical" wetland. I say artifical, because this wetland was created and/or expanded when the Rumford river was diverted and the underpasses at the railroad grade crossings were created in 1952-1958. The North Main Street underpass pumps hundreds of gallons, if not thousands in the wet season, of subsurface water and stormwater runoff a day onto the H&P site. The location of this outlet is at the southwest corner of the fenced -in portion, near the double access gate. When this pipe was originally laid from the underpass to the site, which is now the H&P site, a ditch was dug from the outfall headwall west into the woods. Through the years this ditch was never maintained, and consequently has become blocked with trees, brush, sediments and vegetation. So much so that the ditch backed -up and cut a new path which now runs to the south and along my property line then west till it empties into the backwash channel.The resulting continuous flooding of this previous woodland has now started to kill the tall trees in this area. After reading the information, site inspections and test results that have been done on the H&P site, it appears that both sub -surface and surface water runoff from the south contaminated portion of the fenced -in parcel is flowing south to southwest into the backwash channel. 1 My concern is that the southern most portion of this "artifical" wetland has never been tested.Is this portion also contaminated? It should be tested, especially at the south end of the backwash channel. What is the effect of having hundreds of gallons of water per day dumped upon the contaminated H&P site by the Town of Mansfield? I'm sure that it is increasing the contaminated water flow both above and below ground. I believe that any clean-up remedy for this site should take into consideration the stopping of the unnatural flooding of a woodland/wetland,espasally if it is contaminated.

The air pathway was not scored because there is no documented observed release to the atmosphere and scoring thepotential to release to air would not likely contribute significantly to the overall site score. Although hazardous substances attributable to the site are likely traveling via ground watertoward surface water, the overland flow/flood component ofthe surface waterpathway yields the maximum pathway score of 100. The ground water to surface water component of the surface water pathway is likely to score lower than the overland flow/flood component.

June 16, 1999. (17 pages) July 2001 11 Site Summary The Hatheway and Patterson Company (HPC) site is located in a mixed residential/industrial area. The HPC property is approximately 40 acres and located at 15 County Street in Mansfield, Bristol County, Massachusetts (see Figure 1). The UPC property is bordered to the north by County Street and residential properties, to the south and west by forested and wetland areas, and to the east by T.D. Verroch, Inc, a welding and masonry supply company [refs. 3; 6, p. 2]. In the southern portion of the property, the Rumford River backwash channel flows from east to west. Palustrine forested wetlands surround the Rumford River backwash channel [ref. 11]. The property is roughly divided in half by the Rumford River, which runs north to south, and by a railroad track right-of-way, which runs east to west (see Figure 2). OperationalHistory The HPC site is a former wood preserving facility. Operations at the HPC property included preserving wood sheeting, planking, timber, piling, poles, and other wood products [ref. 7, p. 7]. HPC began wood treating operations at the property in 1953, although HPC operated at the facility since 1927. Little is known about operations between 1927 and 1953, although a portion of the property was used as a coal storage area for'locomotive engines [refs. 4, p. 5; 5 pp. 4 and 5; 16, pp. 1-1, 1-21. HPC historically used various methods and materials to treat wood on the property. From 1953 to 1958, HPC used a solution of pentachlorophenol (PCP) in fuel oil and it also used creosote to treat lumber. From 1958 to 1974 HPC continued to use PCP and also used fluoro-chrome-arsenate-phenol (FCAP) salts in water. From 1960 to 1984, PCP in mineral spirits and chromated copper -arsenate (CCA) in salts were used by HPC. CCA salts and PCP in water were used from 1984 until HPC filed for bankruptcy and ceased operations in April 1993 [refs, 4 ,p 5�5_pp. 4 and 5]. History of Contamination Problems and Stale Actions In 1971, a tar mat approximately 62 feet long and 6 inches deep was discovered by Town of Mansfield and MADEP personnel [ref. 4, p. 5]. At the end of 1972, a citizen complainted of "oily water" and dead water fowl in the Rumford River downstream of Fulton Pond [ref. 25]. The citizen walked up the Rumford River to the origin of the oily discharge and found it to be coming from two large below -ground tanks containing oil, which were part of a "...timber treatment plant on County Street in Mansfield." [ref. 25, p. 6]. The citizen described an "earthen catchment basin" that contained `oil." The oil was discharged from the catchment basin to the Rumford River via a tile train pipe [ref. 25, p. 6]. Five samples (A through E) collected in December 1972 (Sample A was Rumford River sediment and Samples B through E were from tanks) qualitatively revealed PCP contamination up to 3.66 percent by weight (Sample A) [ref. 25, pp. 3, 4, 5, and 8]. Subsequently, MADEP and the Town of Mansfield requested that HPC contain the seepage. By 1973, IIPC developed a contaminated ground water recovery trench located along the east bank of the Rumford Riverjust upstream of its confluence with the Rumford River backwash channel [ref. 4, pp. 5, 8, Figures A-4 and A-7]. Contaminated ground water was pumped by HPC from 1973 through 1976. Oily seepage was again detected in the Rumford River in 1981 by a prospective buyer of the site [ref. 4, p. 81. In 1987, UPC was issued a Notice of Noncompliance (NON) by the MADEP, which ordered that HPC conduct a soils and hydrology assessment of the site [ref. 8, p. 1]. In 1988, MADEP issued UPC a Notice of Responsibility (NOR) and in 1990, MADEP issued a Request for Short -Term Measure (STM) to address the imminent contamination of the Rumford River emanating from the site [refs. 4, p. 8; 17, p. 1-1). In 1992, the U.S. EPA's RCRA program personnel conducted inspections of the HPC facility to determine compliance with RCRA drip pad standards. Observations during these RCRA inspections determined that the drip pads were not in compliance and HPC did not possess appropriate documentation and certification for operation of the drip pads [ref. 4, p. 8]. Penny Engineering, Inc. operated the STM for UPC, which consisted of a retaining wall, sumps, and ground water treatment system located adjacent to the east bank of the Rumford River just upstream of the Rumford River backwash channel [ref. 19, Figure 1]. Penny Engineering, Inc. submitted quarterly monitoring of treated ground water that was discharged to the Rumford River [ref. 19]. In January 1993, MADEP requested that HPC perform a second STM, which called for additional site assessment followed by implementation of environmental controls designed to contain releases at the site [ref. 4, p. 81. EPA Removal Action Because wood treating solvents, chemicals, sludges, tanks, sumps and drums were abandoned by HPC on the property with no electricity or heat, conditions at the site posed a threat of hazardous substance releases. Therefore, in December 1993, EPA Region 1's Emergency Planning and Response Branch initiated a two-year removal action to address problems at the HPC site [ref. 4, p. 1]. Upon initiating the removal action, EPA discovered several process and support buildings that contained large tanks, process vessels, drums, sumps, pits, and various small containers. Outside on the property, EPA discovered three drip pads (CCA, PCP, and Dricon"), treated lumber storage areas, three above -ground tanks containing PCP, another tank containing fuel oil, three tanks containing fire retardant (Dricon'") in water, and six underground storage tanks containing various process wastes [ref. 4, p. 5]. A removal disposal summary table indicated that the following materials were left on the property by HPC [ref. 4, Table C-1]: July 2001 12 • 580 small containers containing flammable liquids, aerosols, and spent batteries; • 12 chemical -filled drums; 45,861 gallons of Dricon" liquid (from tanks T-01, T-02, T-04, and sumps/pits); • 60 drums (approximately 3,300 gallons) of waste CCA liquid from tanks T-17 to T-21; 65 drums (approximately 3,575 gallons) of liquid waste from tanks T-13, T-14, T-15, T-23, and T-29; • 62 drums (approximately 3,410 gallons) of waste sludges from tanks T-12a, T-12b, T-16, T-13, T-14, T-27, T-29, and a PCP sump; 88 drums (approximately 4,840 gallons) of waste PCP sludge from tanks T-05 and T-31 and PCP -contaminated soil/debris; 26,836 gallons of wastewater and sludges from tanks T-09, T-10, T-I1, T-26, T-30a, T-30b, T-30c, T-31, and T-32; and 10,030 gallons of waste PCP liquid from tanks T-05, T-06, and T-07. Although these materials were removed from the site and either recycled or disposed of at an approved facility, they are likely to have contributed to soil, ground water, and surface water contamination at the site prior to the removal action [ref. 4, p. 40]. Although the EPA removal action addressed direct contact threats posed by contaminated soils by covering them with asphalt or gravel, the contaminated soils still remain at the site. Only portions of the contaminated soils (evaluated as Sources 1 and 2 in this documentation record) were covered, and future hazardous substance migration to ground water and surface water is not mitigated by these covers [ref. 4, p. 1, figures A-4 to A-8]. EPA's removal action concluded in September 1995 [ref. 4, p. 40]. BRS Documentation Record Overview For IIRS scoring purposes in this documentation record, the operations of HPC have been separated into two areas: the former operations area located north of the railroad tracks; and the southern wood storage areas south of the railroad tracks. Contaminated soil in the former operations area is evaluated as Source I and contaminated soil in the southern wood storage area is evaluated as Source 2. The ground water migration pathway and the surface water migration pathway overland flow/flood component are scored in this documentation record.

Wood treating operations formerly took place north of the railroad tracks on both sides of the Rumford River, which flows northeast to southwest down the middle of the property. The far northwest comer of the property, where wood treating and storage occurred, and where the Rumford River enters the property, is included in this source. In this area of the facility, HPC preserved and stored wood products, including sheeting, planking, timber, pilings, poles and other wood products using a variety of methods and materials [ref. 7, p. 7]. Several buildings remain in the former operations area, including cylinder building numbers 1, 2, and 3, the kiln building, the mill building, the stacker building, the Dricon" building, an office, and a laboratory. The wood treating chemicals were stored in above ground storage tanks (ASTs) and underground storage tanks (USTs) and sumps located inside and outside the former process buildings [ref. 6, p. 2-41. Three concrete drip pads also remain [ref. 4, p. 5]. RCRA inspections conducted in March 1992 revealed that the drip pads were "riddled with cracks, seams, gaps, and corroded areas in the concrete, and portions of the drip pads were not curbed or bermed" [ref. 7, p. 2-3 ]. The following methods and materials were used by HPC to preserve its wood products [ref. 7, p. 7]: From 1953 to 1958, a solution of PCP in fuel oil, as well as creosote, was used to treat (dip, not pressure -treat) lumber, allowing chemicals to drip off the wood products onto the soil [ref. 4, pp. 5, 8]. From 1958 to 1974, solutions of PCP in fuel oil and fluoro-chrome-arsenate-phenol (FCAP) salts in water were both used in a pressure treatment process. (FCAP contains 25% sodium fluoride, 25%sodium arsenate, 37.5%sodium chromate, and 12.5%2,4-dinitrophenol) [ref. 4, p. 21. • From 1960 to 1984, PCP in mineral spirits was used to pressure treat lumber [ref. 4, p. 51. • From 1974 to 1984, PCP in fuel oil and chromated copper -arsenate (CCA) salts in water were used [ref. 4, p. 5]. • From 1984 until operations ceased in 1993, solutions of CCA salts in water and PCP in water were used [ref. 4, p. 5). • Wood was also infused with a fire retardant composed of boric acid and anhydrous sodium tetraborate [ref. 7, p. 2]. EPA's Wood Preserving RCRA Compliance Guide indicates that the majority of contamination at older facilities that operated for many years before current environmental regulations and disposal options existed was caused by.poor management practices including the allowance of excess preservation called "kickback" to drip onto the ground from treated charges of wood. Kickback is wood preservative that is generated from treated wood as the wood begins to return to normal pressure after a pressure treating process (ref. 48, pp. 2-8, 4-22). When the site was abandoned in May 1993, wood -preserving products and waste were left on site [ref. 5, p. 3]. EPA's TAT contractors reported the presence of 20 55-gallon drums and eight ASTs located in various process buildings. TAT estimated that these contained a total of 45,000 gallons of preservatives with various percentages of PCP, CCA, and Dricon'. One AST contained fuel oil [ref. 5, p. 3-4]. Six USTs containing various wastes, were also present in the vicinity of cylinder buildings 1 and 2 [ref. 5, p. 1-2]. Most of the sumps in the buildings also contained water and sludge from the treatment process [ref. 4, p. 5). Observations of the 45 foot by 120 foot CCA drip pad along the northeast boundary of the site during the 1998 START investigation noted that the drip pad was stained green, typical of copper salts [ref. 6, p. 4]. The EPA removal action report states that HPC left wood -treating solvents and sludges in tanks, sumps, and drums when they abandoned the site. The site was without heat or electricity and impending freezing weather conditions posed the threat of release of these chemicals [ref. 4, p. 8]. EPA ultimately removed 82,727 gallons and 355 drums of material for disposal or reuse [ref. 4, Table C-11. During this investigation, EPA conducted a field screening analysis of arsenic in soil [ref. 4, p. 321. July 2001 15 EPA also graded several portions of the former operations area of the site to control runoff and placed temporary caps of geotextile fabric, gravel, and asphalt in areas around the mill building, the buildings for cylinders I and 2, the kiln building, the Dricon" building, tanks holding fuel oil (No. 8) and PCP (Nos. 5, 6, and 7), the contaminated areas adjacent to the CCA drip Pad, and various other areas. [ref. 4, p. 34-37). EPA also had a large portion of deteriorated pavement repaved [ref. 4, p. 37-391. Many investigations have been conducted at the site, including the. following: • In 1987, consultants for HPC prepared a Soils and Hydrogeologic Investigation (Phase I). This investigation was required in a Notice of Noncompliance (NON) letter from MADEP [ref. 8, p. 1]. • In 1988-89, consultants for HPC prepared a Phase II site investigation required in a Notice of Responsibility (NOR) letter from MADEP [ref. 16, pp. 1-1, 3-1, 3-7]. • In 1993, EPA's removal program conducted a high priority PA/SI [ref. 5). • In 1994, MADEP prepared a preliminary assessment report [ref. 7]. - In 1994, EPA's ERT prepared a Soil Sampling and Field Screening of the HPC site [ref. 53]. July 2001 16 2.2.2 HAZARDOUS SUBSTANCES ASSOCIATED WITH SOURCE 1 The following soil samples were collected during a May 1988 soils and hydrogeology investigation of the HPC site by Keystone Environmental Resources, a consultant for HPC [ref. 8, Figure 3-1]. See Figure 3-1 of Reference 8 for sample locations. HPC states that samples B-1, B-2, and B-3 show little, or no, impact from site operations [ref. 8, p. 4-2]. However, B-2 shows significantly more contamination than either B-I or B-3. Therefore, samples B-1 and B-3 will be considered background soil samples although they may be, to some degree, impacted by site operations. For certain substances that are not naturally occurring or ubiquitous, no background levels are used for comparison, despite the concentrations in samples B-1 and B-3.

Substance is associated with site operations only. NR = Not reported. In December 1994, EPA's ERT finalized a soil sampling and field screening report [ref. 53]. This investigation consisted of collecting 43 soil samples from five areas at the site. Areas 1, 2, 3, and 4 are situated in Source 1, while Area 5 comprises Source 2 [ref. 53, Figure 2]. Each of the 43 samples was analyzed for chromium, copper, arsenic, and lead using field portable July 2001 17 x-ray fluorescence (XRF) analysis. Each of the 43 samples was also analyzed for PAHs and PCP using immunoassay field screening kits. To meet quality assurance objectives, 10 percent of the samples were sent to fixed laboratories for confirmatory analysis using Target Analyte List (TAL) metals and PCP/creosote compounds [ref. 53, p. 11. Field and confirmation sample analysis revealed PCP contamination greater than 5 ppm in the former operations area (Source 1) [ref. 53, p. 12]. Arsenic concentrations were greater than 30 ppm in all samples collected in the Source I area. Chromium was detected at greater than 1,000 ppm in all samples collected in the former operations area of Source 1. Copper and lead were also detected at elevated concentrations in the Source 1 area [ref. 53, p. 12]. No soil samples from Source I have been analyzed for dioxins and furans. 2.2.3 HAZARDOUS SUBSTANCES AVAILABLE TO A PATHWAY Containment Description Release to ground water: This contaminated soil source was not intended to be a waste management unit and has come to be located here via migration, deposition, and spills. No evidence exists to indicate that a liner is present below the contaminated soil. The depth of contamination also indicates that no liner is present. Release via overland migration and/or flood: The source contains neither of the following: a maintained, engineered cover or functioning and maintained run-on control system and run-off management system. This source was not intended to be a waste management unit and has come to be located here via migration, deposition, and spills. EPA has paved and graveled various areas of the source to address imminent threat; no system has been installed to manage run-on and run-off. 2.4.2 HAZARDOUS WASTE QUANTITY 2.4.2.1.1 Hazardous Constituent Quantity Containment Factor Value 10 10 Insufficient information is available to estimate the hazardous constituent quantity. 2.4.2.1.2 Hazardous Wastestream Quantity Insufficient information is available to estimate the hazardous wastestream quantity. 2.4.2.1.3 Volume Ref. 8, Appendix A 4, pp. 34-39 The contaminated soil northeast of the railroad tracks appears to be contaminated to a significant horizontal and vertical extent; however, no volume estimate is provided here because of the limited number of available data points. The vertical extent of Source I varies, but contamination has been detected at 8-10 feet below ground surface [ref. 8, Tabfe'4-2]. Extensive ground water contamination exists in the Source 1 vicinity; also indicating that soil contamination extends down to the water table in this area. However, because the volume cannot be adequately determined, the area (Tier D) measure will be used. Volume Assigned Value: 0 2.4.2.1.4 Area The area of the source is based on Figure 3-1 of Reference 8 and Figure 2 of Reference 53. Figure 2 of this documentation record also shows the sample locations used to define Source 1. The area between the samples listed in Table 1 above cannot be measured with certainty, thus the area of Source I is assigned a value of unknown, but greater than zero. Area Assigned Value: >0 2.4.2.1.5 Source Hazardous Waste Quantity Value Highest value assigned from reference 1, Table 2-5: >0 July 2001 18 2.2.1 SOURCE IDENTIFICATION Source 2: Contaminated Soil in Southern Wood Storage Area of Site Source Tyne: Contaminated Soil Description and Location of Source (with reference to a map of the site): The southern portion of the property includes all areas southeast of the railroad tracks depicted on Figure 2. Activities, known to have taken place south of the railroad tracks include storage of treated wood and response activities conducted by HPC. Most of these activities occurred on the eastern quarter of the property, south of the railroad tracks. In this area of the facility, HPC stored treated wood products in several locations including two buildings and several uncovered areas [ref. 5, p. 2, Figure 2]. The soil in this portion of the property is contaminated with metals, phenolic compounds, volatile organic compounds (VOCs), PAHs, and dioxins and furans. According to EPA's Wood Preserving RCRA Compliance Guide, wastes generated at wood preserving plants that use or formerly used chlorophenolic preservative formulations are likely to contain dioxins. The majority of contamination at older facilities that operated for many years before current environmental regulations and disposal options existed was caused by poor management practices, including the allowance of excess preservation called "kickback" to drip onto the ground from treated-chargesof wood. Kickback is wood preservative that is generated from treated wood as the wood begins to return to normal pressure after a pressure treating process [ref. 48, pp. 3-7, 2-8, and 4-22]. This document also notes that preservative drippage and process residuals may accumulate in pathways over which treated wood is transported and in treated wood storage yards including preservative that is washed off treated wood by rainwater [ref. 48, p. 4-4]. This area of the site is level because of filling activities but drops off abruptly by 10 to 20 feet to the south in a line running east -west [ref. 7, p. 2). South of this fill line is a densely wooded wetland area bounded by the Rumford River backwash channel. The extensive filling of the site included the rerouting of the Rumford River from its previous course through this area of the site to its present course to the west [ref. 5, p. 2). The HPC facility originally included only the land between County Street and the railroad tracks as far west as the Rumford River. Land west of the Rumford River was used by Penn Central Railroad for bulk chemical transfer, storage of electric/utility poles, and storage of railroad ties [ref. 8, p. 1]. HPC purchased this land in 1978: In 1981, HPC purchased the land south of the railroad, which had been used for coal storage prior to 1955 [ref. 8, p. 1]. In 1972, a tar mat was discovered on the banks of the Rumford River on the southern portion of the HPC property. It appeared to originate from the eastern bank of the Rumford River [refs. 4, p. 8; 7, p. 7; 8, p. 1-2; 16, p. 2-1]. HPC took efforts to control the seep using booms and sorbents, installation of a system to pump oil -contaminated ground water, and a treated plywood bulkhead to trap the seepage. In 1973 seepage appeared farther downstream and in 1974, HPC installed four recovery pits along the river [ref. 16, p. 2-1]. By 1982, the recovery system was producing only traces of oil [ref. 4, p. 8]. However, analyses of soil samples by a prospective buyer of the property revealed "oily soils and/or oily groundwater" [ref. 7, p. 7]. According to HPC's consultant Keystone, vandals shot holes in several drums of recovered oil that'were stored on the HPC property along the east bank of the Rumford River and then tipped the drums over allowing the oils to seep into the ground and the river [ref. 16, p. 2-3). . In 1990, after "oily seepage" was again reported on the Rumford River in the vicinity of the HPC property, MADEP issued a request to IIPC for a Short Tenn Measurelo address the imminent hazard to the river caused by on -site operations [ref. 7, p. 7]. Keystone conducted an investigation, sampling stained soil along the river bank and found that a major constituent of the contamination was semi -volatile organic compounds (SVOCs) [ref. 17, p. 2-7]. UPC also collected soil samples during installation of three piezometers located along the river [ref: 17, p. 2-7]. In 1991, HPC constructed a collection trench along the eastern bank of the Rumford River; the intercepted contaminated ground water was used by HPC as process make-up water [ref. 8, p. 1-1]. During a 1993 EPA TAT investigation, EPA personnel observed a pile of contaminated soil, apparently excavated from the trench HPC dug along the Rumford River. Also during this investigation, EPA personnel observed "oily seeps" along the southern edge of the fill line and associated areas of stained soil and stressed vegetation [ref. 5, p.1-2]. EPA collected samples from the "oily seeps," the pile of contaminated soil, and stained soils adjacent to and south of the railroad right-of-way [ref. 5, p• 3]• July 2001 19 The EPA removal action report states that as part of the wood preservation process, HPC allowed chemicals to drip off the treated lumber onto underlying soils. In several portions of the southern area of the site EPA placed temporary caps of geotextile fabric and gravel, including a rectangular area next to a large bedrock outcrop, and areas adjacent to the roadway and near the former storage shed [ref. 4, p. 35]. Many investigations have been conducted to identify the extent of soil contamination in this area of the HPC site, including the following: • Keystone's 1988-89 Phase II Site Investigation required in allotice of Responsibility (NOR) letter from MADEP [ref. 16, pp. 1-1, 3-1, 3-7]• • EPA Region 1 Removal Program's 1993 PA/SI [refs. 4, p. 1; 5, p. 5]. • EPA's 1995 Emergency Removal Action (ERA) [ref. 4, p. 23). • EPA's 1998 Removal Branch sampling event (dioxin contamination assessment) [refs. 40; 49). 2.2.2 HAZARDOUS SUBSTANCES ASSOCIATED WITH THE SOURCE 2 The analytical results identified below come from two sampling events where soil samples were collected in the Source 2 area (contaminated soil south of the railroad tracks and east of the Rumford River). The VOCs and SVOCs in the first table are from the HPC Phase II sampling event [ref. 16), while the metals and dioxins/furans in the second table are from the 1998 EPA Removal Branch sampling event [ref. 40; 49). To identify the concentrations of hazardous substances -significantly above background, soil samples P-1 and P-2 were used to represent background levels for the non-dioxin/furan hazardous substances. The HPC Phase rI indicates that these two samples may represent concentrations associated with railroad bulk storage [ref. 16, p. 2-9]. The background sample is not used for comparison to chlorinated phenolic compounds because they are not naturally occurring and are directly associated with site operations and wastes at the site.

No evidence exists to indicate that a liner is present below the contaminated soil. The extreme depth of contamination also indicates that no liner is present. None of the borings within the source area appear to have encountered a liner. Release via overland migration and/or flood: The source contains neither of the following: a maintained, engineered cover or functioning and maintained run-on control system and run-off management system.

The vertical extent of Source 2 varies, but has beendetectedat 8-10 feet below ground surface [ref. 8, Table 4-2]. Extensive ground water contamination exists in the Source 2 vicinity, also indicating that soil contamination extends down to the water table in this area. Because the volume of Source 2 cannot be adequately determined, the volume of Source 2 is assigned a value of zero and the area (Tier D) measure will be used.

Some of these other possible sources are described below. These hazardous substances in theses other possible sources are described in the Site Description section of this documentation record. 1. ASTs and USTs: A total of 32 above or below ground chemical or waste storage tanks were identified on the property during the Emergency Removal Action performed by EPA from December 1993 to September 1995 [ref. 4, Appendix B, Table C-1]. 2. CCA. PCP, and Dricon`' drip pads: Large drip pads were used to allow excess CCA, PCP, or Dricon" to drip onto the ground from freshly treated wood. There were separate dip pads located in the main operating area of the HPC facility for wood treated with CCA, PCP, or Dricon" [ref. 49, p. 4, Figure 3]. 3. CCA, PCP, and Dricon" sumps: The sumps were used to capture excess drippings from the treated wood placed on the drip pads. There is a sump for each of the CCA, PCP, and Dricon" drip pads. According to the EPA's removal action report, these were filled with chemicals and sludge [ref. 4, Table C-1]. 4. Drums and miscellaneous small containers: Drums containing flammable liquids, contaminated dust and debris, small containers of spent batteries, and miscellaneous chemicals were found abandoned on the site when the EPA removal team first entered. These materials were disposed of off site by the EPA removal team [ref. 4, Table C-1]. 5. Other contaminated soil: A ditch from the treating area runs south of and parallel to the railroad tracks between the railroad tracks and the bedrock outcrop. Monitoring well MW-6, located in the vicinity of this former ditch; has shown high levels of PCP [ref. 8, p. 4-12]. Upon constructing the STM trench/recovery system, BPC contractors stored a pile of approximately 4 cubic yards of "oil -stained" soil near the construction location [refs. 18, p. 2-2; 19). This pile was again observed on the site during a START site visit in April 1998 [ref. 50, p. 7). July 2001 23 3.0 GROUNDWATER MIGRATION PATHWAY 3.0.1 GENERAL CONSIDERATIONS Ground Water Migration Pathwav Description The site is located approximately 30 miles west of the Atlantic coast. Present topography at the site has little relief, except the bedrock outcrop in the southern half of the site, which has an elevation approximately 20 feet above the surrounding terrain, and the river channel which bisects the plant from north to south. Because the site has been extensively filled, its original topography is unknown [ref. 8, p. 2-1]. The EPC site is located within the Mohawk Division of the New England physiographic province. The State of Massachusetts is characterized, geologically, by largely unconformable, exposed metamorphic and igneous bedrock, which have been further deformed and complicated by major faults and folds. The southeastern portion of the state and part of Rhode Island are dominated by a major depositional area, the Narragansett Basin, formed in the Triassic -Jurassic period [ref. 8, p. 3-1]. The site is located in Mansfield, which lies approximately four miles south of the contact between the Narragansett Basin and the adjacent igneous bedrock of the Proterozoic. The uppermost bedrock unit in the basin, the Dighton Conglomerate, has been identified only in the southwestern section of the basin east of Mansfield. The Dighton overlies the Rhode Island Formation of the Pennsylvanian, which is the uppermost bedrock beneath the site. Faults in the underlying crystalline bedrock near the _ border of the basin trend north-northeast and their impact appears to diminish within the basin due to the depth of the overlying sedimentary formations. The east -northwest trending Mansfield Syncline lies to the south of the Hatheway and Patterson facility and has a south-southwest dip, thus exerting a gentle south-southeast dip in the Rhode Island Formation [ref. 8, p. 3-1]. The unconsolidated deposits which immediately overlie bedrock throughout much of the Narragansett Basin are composed of -till from the various glacial episodes. In some areas this till layer is approximately 15 feet thick. The glacial till is highly permeable and composed of fine to coarse sandy gravel with lenses of sand, silt, and clay. Deposition of this material in preglacial valleys has provided thick sequences of permeable material which are a major source of ground water for public water systems. Near rivers and streams, the glacial till unit has been largely eroded and replaced by recent.alluvial sand and gravel channel deposits. The near -surface deposits (sometimes overlain by fill) at the Hatheway and Patterson facility are primarily composed of these alluvial materials deposited by the Rumford River. The alluvium is sometimes underlain by a thin layer of glacial till, but frequently it is in direct contact with the underlying bedrock. The bedrock beneath the site slopes steeply from north to south at a ratio of approximately 1:8, with an anomalous outcrop south of the railroad tracks [ref. 8, pp. 3- 1, 3-2, 3-3, Figures 3-2 and 3-3]. The saturated interval was encountered during drilling at an approximate depth of 6 feet below grade, throughout the site. At those locations where bedrock was encountered at shallow depths, the saturated interval was elevated, generally 3 feet below grade. Ground water elevations in shallow monitoring wells (MW-1, MW-2, MW-3, MW-5A, MW-6, and MW-7A) were used to determine ground water flow patterns at the site. The ground water elevations indicated that shallow ground water flows in a south/southwesterly direction in the eastern portion of the site, toward the Rumford River and the Rumford River backwash channel [ref. 8, p. 3-3 and Figure 3-41. The MADEP has reported that subsurface contamination likely flows through the former beds of the Rumford River (alluvial deposits) as indicated by seep outbreaks observed along south-central property areas, and historical outbreaks of tar mats along the Rumford River as it now passes by former riverbed flow paths. The flow course of the Rumford River has been altered several times in the past [ref. 5, p. 9]. Prior to 1850, it flowed west -to -east through the former operations area, turning southward between the current location of the Mill Building and the Cylinders No.I and 2 Building, continuing to the Rumford River backwash channel. Between 1945 and 1950, its flow was altered to its current course [ref. 8, p. 3-5]. To address imminent hazard, in 1990 the MADEP issued HPC a Request for STM. HPC's consultant installed a system to control ground water and oils migrating to the Rumford River from the oil -stained portion of the river bank [Refs. 5, p. 8; 7, p. 7, 8; 17, p. 1-1; 19, Figure 1]. In 1993, following HPC's bankruptcy filing, the ground water treatment system ceased operation. At that time, a layer of oil was detected floating on ground water in monitoring wells that had previously been clean. EPA and Penney Engineering, HPC's environmental consultant, speculate that the significant amount of water used to fight a fire at the adjacent agricultural supply facility in July 1993 affected the flow of contaminants in the ground water. It was also determined that the PCP contaminated oil was moving off the property to the southeast, into the wetlands, the Rumford River, and eventually to Fulton's Pond [Ref. 5, p. 8]. July 2001 24 GW-General Aquifer/Stratum 1 (shallowest): Alluvial/Glacial Deposits Recent alluvial sand and gravel channel deposits and glacial till comprise the uppermost stratum beneath the site. The near - surface deposits (sometimes overlain by fill) at the Hatheway and Patterson facility are composed of these alluvial materials. Site -specific geologic information generated during December of 1987 indicated that the uppermost unit generally encountered at the site is composed of various fill materials (approximately 2 feet in depth), underlain by the alluvial unit composed of sand with little to some gravel and little silt. The alluvial unit is sometimes underlain by a thin layer of till. The alluvial/glacial deposits range in depth at the site from 0 feet (at the bedrock outcrop) to more than 35 feet (MW-7B) closer to the Rumford River [Refs. 8, Appendix A;16, Appendix B]. No intervening layers exist between the alluvial/glacial deposits and the underlying bedrock aquifer [ref. 8, pp. 3-1 to 3-41. The ground water flow in this stratum is unconfined and generally to the south/southwest, parallel to the Rumford River. Flow gradients on the western side of the Rumford River were not determined due to too few measurement locations to triangulate the flow direction [ref. 8, pp.3-3, 3-4, Table 3-1, Figure 3-41. The average hydraulic conductivity of the alluvial deposits - beneath the site, as measured by contractors for HPC is 3.6 x 10' centimeters per second (cm/sec.), based on measurements from MW-2, MW-4, and MW-7A [ref 8, p. 3-4). Aquifer/Stratum 2 (deepest): Bedrock (Rhode Island Formation) The Dighton overlays the Rhode Island Formation of the Pennsylvanian, which is the uppermost bedrock beneath the site. Faults in the underlying crystalline bedrock near the border of the basin trend north-northeast and their impact appears to diminish within the basin due to the depth of the overlying sedimentary formations. The east -northwest trending Mansfield Syncline lies to the south of the HPC facility and has a south-southwest dip, thus exerting agentle south-southeast dip in the Rhode Island Formation fref. 8, p. 3-I]. Ground water in the bedrock stratum exists in faults and fissures and the bedrock has an average hydraulic conductivity of 5.66 x 10' cm/sec: [ref. 16, p. 2-2, Appendix D]. Ground water levels in the bedrock stratum are consistent with those in the overlying alluvial/glacial stratum, indicating that ground water in the bedrock and alluvial/glacial stratum act as a single hydrogeologic unit [ref. 16, Table 2-1, Figures 2-7 to 2-111. In addition, the hydraulic conductivities of the alluvial/glacial deposits (shallowest stratum) and the bedrock (deepest stratum) are within an order of magnitude [refs. 8, p. 3-4; 16, Appendix D]. Ground water contamination, attributed to the site, has also been detected in all three on -site bedrock monitoring wells [ref. 16, Table 2-6]. For HITS scoring purposes, these two stratum are evaluated as a single aquifer. July 2001 25 GW-General 3,1 LIKELIHOOD OF RELEASE 3.1.1 OBSERVED RELEASE Aquifer Being Evaluated: Alluvial/Glacial/Bedrock (from this point on referred to as the alluvium/bedrock aquifer) Direct Observation An observed release by direct observation is not evaluated in this documentation record. Chemical Analvsis In November 1987, as part of a Phase I investigation required under an MAEQE notice of noncompliance, HPC's consultant, Keystone Environmental Resources (Keystone) installed monitoring wells MW-1 through MW-4, MW-5A, MW-513, MW-6, MW-7A, and MW-713 to determine potential sources areas. MW-1 was installed at a location hydraulically upgradient of the other wells, and on a lateral gradient with, and adjacent to, the wood -treating area (ref. 8, p. 3-2). In response to a Notice of Responsibility from MAEQE, Keystone performed a Phase II investigation for HPC, including the installation of 6 additional monitoring wells MW-8A, MW-813, MW-9A, MW-913, MW-10, and MW-11. In addition, Keystone installed two piezometers P-I and P-2, and an additional pump test/monitoring well, PW-1 [ref. 16, pp. 2-2, 2-3]. Although numerous sampling events document hazardous substances in the alluvium/bedrock aquifer attributed to the HPC site, the analytical results of the December 1989 Phase II Site Investigation and Preliminary Health and Environmental Assessment (Phase II Site Investigation), prepared for HPC [ref. 16] are presented below to document the observed release to the alluvium/bedrock aquifer. The Phase II Site Investigation refers to three rounds of samples collected from each monitoring well (February 6, 1989, March 2, 1989, and April 5, 1989) [ref. 16, p. 2-6]. However, results from only selected wells were provided for the February and April events [ref. 16, Appendix C]. Therefore, this documentation record will use the results from the March 2 sampling event to document an observed release to ground water by chemical analysis. Additional ground water sampling events are summarized following the Phase 11 Site Investigation results. - Background Sample: One monitoring well (MW-11) is located hydraulically upgradient of the site and is less impacted by the site. Samples collected from MW-11 do show some contamination originating from the site (e.g., total copper and total chromium); however, it reflects background conditions for most site -related hazardous substances [ref. 16, pp. 2-10, 2-19, 3-25, App. C1. MW-I is considered an observed release well because although it is slightly upgradient of the operations at the site, it is immediately adjacent to, and hydraulically lateral from, the former treating area (part of Source 1). Samples from MWA also show significant contamination attributable to the site [ref. 16, Fig. 2-1, p. 2-14]. Two of the monitoring wells used to establish the observed release by chemical analysis are entirely screened in the bedrock; MW-813 and MW-9B [ref. 16, Appendix B]. Currently, there are no upgradient or "background" wells screened in the bedrock aquifer to establish a background level for the bedrock stratum. The analytical results from these two bedrock wells are compared to the background alluvium well results for two reasonsi (I) the water levels in these wells reflect water table (unconfined) conditions similar to those in the alluvium wells; and (2) HPC's Phase R Site Investigation states that contamination in these deep bedrock wells is a result of downward migration of contamination from the site [ref. 16, p. 2-19 and Table 2-1]. The slope of bedrock/alluvium interface beneath the site makes it possible for some of the alluvium wells to be deeper than some bedrock wells (e.g., MW-7B and MW-8B) [ref. 16, Table 2-1, Figs. 2-3 and 2-4].

By comparing the elevations to Appendix A ofreference 8 and confirming the general site elevations with the topographic map, it was determined that the monitoring well casing elevations listed in Reference 16 (Table 2-1 and Appendix B) are 75.4 feet too low. The reason for this error appears to be an incorrect transcription of elevations on the well logs in Appendix B of reference 16. Therefore, the well casing elevations for those wells that only appear in reference 16 Appendix B (i.e., M W-8A to MW-12, which were installed after the Soils and Hydrogeologic Investigation) have been corrected to account for this error. Therefore, 75.4 feet has been added to each of the screen intervals in the cited reference. 2 Well logs are not available for MW-7A, MW-7B, and MW-6. Screen intervals for wells MW-7A and MW-7B are estimated based on a cross-section [ref. 16, Fig. 2-3). Reference 16 refers to MW-6 as a "shallow" well. Other "shallow" wells discussed in Reference 16 are all screened in the alluvium. Therefore, MW-6 is evaluated as an alluvium well. July 2001 27 GW-Likelihood of Release Hazardous Substance Bkgd.

All samples were analyzed for base/neutral acid extractables (BNAs) using EPA Method 8270, metals (total and dissolved), phenol, and other substances using various methods [ref. 51, p. 24]. Samples collected from MW-5A and MW-12 were analyzed for dioxins and furans as part of this sampling event [ref. 51, p. 8). The sample collected from MW-12 was considered `oil," as it represented product floating on the top of the aquifer [ref. 51, p. 23]. Analytical results showed extensive contamination of various substances. Selected concentrations detected in a ground water sample from MW-12 include: 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TCDD) at up to 37.6 parts per trillion (ppt); 2;3,7,8- tetrachlorinated dibenzofuran (TCDF) at up to 211 ppt; 1,2,3,4,7,8-hexachlorinated dibenzo-p-dioxin-(HXCDD) at 14,860 pint, 1,2,3,6,7,8-HxCDD 352,060 ppt; total TCDD at 227 ppt, total TCDF at 2,460 ppt; total HxCDD at 790,840 ppt; and total heptachlorinated dibenzo-p-dioxin (HpCDD) at 4,316,360 ppt. Additional hazardous substances detected in the ground water samples include pentachlorophenol at 1,710 pg/L in MW-5A, at 1,700 pg/L in MW-7A, and 1,220 pg/L in MW-5B; and arsenic at 363 pg/L in MW-3 and at 219 pg/L in MW-6 [ref. 51, pp. 5-9]. No samples were collected from MW-I1, the background well, during this round of sampling, therefore, these concentrations are presented to further support the observed release documented by the 1989 Phase II Site Investigation. Attribution: The hazardous substances detected at observed release concentrations in ground water are attributed to operations and sources at the HPC site. They are found in sources at the site, which were not contained against a release to ground water [see sections 2.2.2 for Sources 1 and 2]. The substances detected in the observed release by chemical analysis consist of either the constituents of wood preserving materials used at the site or substances created by the transformation of constituents used at the site [refs. 16, p. 1-2; 52, Box C; 45, p. 1]. From 1953 to 1993, HPC preserved wood products using a number of chemicals, July 2001 29 GW-Likelihood of Release including: PCP in fuel oil, creosote, fluoro-chrome-arsenate-phenol salts in water, and chromated-copper-arsenate salts in water [refs. 4, pp. 5-8; 16, pp. 1-1, 1-2; 49, p. 4]. The wood products treated at HPC were allowed to drip onto the ground or onto concrete drip pads that were found to be riddled with cracks, gaps, and corroded areas during a RCRA inspection [ref. 7, p. 8]. The former General Manager and President of HPC (from 1973 to 1993) admits in sworn testimony that PCP, CCA, and other wood treating products were allowed to drip onto bare soil throughout the entire site [ref. 44, pp. 30, 32, 61]. HPC's Phase II report concludes that "...environmental impact from plant operations has been defined to the north, by MW-1 and MWA I and to the west by MW-4" fref. 16, p. 2-19]. HPC's Phase II report further concludes that deep wells MW-713 and MW-913 indicate vertical migration attributable to the site into the lower alluvial aquifer and the upper bedrock aquifer [ref. 16, p. 2-19]. HPC also admits that the ground water contamination plume extends within the Rumford River backwash channel area [ref. 16, p. 2-19). In addition, the ground water well closest to the Rumford River and the Rumford River backwash channel (MW-10) has consistently shown contamination (including PCP and PAHs) attributable to the HPC site, indicating contaminant migration toward, and even entering, surface water [ref. 16, Figure 2-17).

Figure 3 of this report shows the drinking water supply wells within 4 radial miles of the HPC site [Figure 3 of this report; ref. 9]. Nearest Well Factor Value: 5 (ref. 1, Table 3-11) July 2001 33 GW-Targets 3.3.2 POPULATION 3.3.2.4 Potential Contamination Although private drinking water wells exist within 4 miles of the HPC site, these private wells have not been scored in this documentation record [ref. 27]. Four municipalities have public drinking water wells within 4 miles of the sources at the HPC site [see Figure 3 of this documentation record]. The four municipalities are the Town of Marisfield, the Town of Foxborough, the Town of Sharon, and the Town of Easton [refs. 9; 20; 21; 22; 24; 26]. Each municipality's water supply system is described below. Town of Mansfield Water Department (MWD) The water supply system for the Town of Mansfield is provided by the MWD and serves a total population of 20,400 people (6,540 service connections) (ref. 20, p. 1, 3], The system includes eight wells: 1. Cate Springs Well No. 1; 2. Albertini Well No. 2; 3. Albertini Well No. 3; 4. Witch Pond Well No. 6; 5. Dustin Well No. 7; 6. Prescott Well No. 8; 7. Prescott Well No. 9; and 8. Walsh Well No. I 1 (considered a single well -as noted by its having only one water supply ID No.-, although it consists of 42 co -located, blended wells) [ref. 20]. All of the wells draw from the alluvium/glacial aquifer (referred to as the "overburden" in the reference) and the entire system is blended prior to distribution [ref. 20]. No one well contributes greater than 40% to the overall system (the total contribution of the largest well, the Walsh Well, is only 25% of the total system) [ref. 20, p. 3]. One additional well, Albertini Well No. 4, is no longer used [ref. 20, p. 1]. All eight wells are located within 4 miles of the HPC site [ref. 20, p. 3; Figure 3]. Calculation: 20,400 people/8 wells = 2,550 people per well. Town ofFoxboroueh Water Department (FWD) The water supply system for the Town ofFoxborough is supplied by the FWD and serves a total population of approximately 16,500 people [ref. 26, p. 1]. The system includes I 1 wells (Well Nos. 1, 2a, 4, 5, 6, 7, 8, 9, 10, 12, and 13) located throughout six well stations (Station Nos. 1, 2, 3, 3a, 4, and 5) [ref. 26]. Water is blended and pumped to two holding tanks, where it is gravity -fed to the system [ref. 26). All wells are screened in the "overburden" (alluvium/glacial aquifer) and no one well contributes greater than 40% to the total system [ref. 26]. All 11 FWD wells are within 4 miles of the HPC site [ref. 26; Figure 3). Calculation: 16,500 peopleA I wells = 1,500 people per well. Town of Sharon Water Department (SWD) The water supply system for the Town of Sharon is supplied by the SWD and serves approximately 16,000 to 17,000 people [ref. 22]. The system includes six wells (Well Nos. 2, 3, 4, 5, 6, and 7) [ref. 22]. No one well contributes greater than 40% to the overall system [ref. 22]. All but one well is screened to about 50 feet below ground surface, with one down to 80 feet below ground surface [ref. 22]. Other wells in the area screened at around 50 feet below ground surface are screened within the alluvium/glacial aquifer [ref. 21; 23; 26]. Three of the SWD wells (Well Nos. 5, 6, and 7) are within 4 miles of the HPC site [ref. 22; Figure 31. Calculation: 16,000 people/6 wells = 2,667 people per well. Town of Easton Water. Department (EWD) The water supply system for the Town of Easton is supplied by the EWD [ref. 24]. Although two of the EWD wells (Well Nos. 3 and 5, southeast of the site) appear to be within four miles of the site, EPA did not score them as being within the distance limit because their.exact distance from sources could not be confirmed and the additional target points for these wells would not affect the potential targets factor value [ref. 24; Figure 3].

The property is generally divided by the Rumford River into eastern and western portions [ref. 49, Figure 4]. The Rumford River flows generally north -to -south through the main UPC facility [refs. 3; 16, p. 2-6]. Two branches of the Rumford River converge near the northern -most portion of the property [ref. 31. Surface water runoff from the western and northern portions of the property flows over land into the Rumford River [ref. 16, Figures 2-14a and 2-14b]. Surface water runoff from the eastern and southern portions of the HPC property may flow directly to the Rumford River or southward into the adjacent wetlands and a shallow body of water, referred 10 as the Rumford River backwash channel [ref. 16, p. 2-6, Figure I-2]. Although the Rumford River backwash channel appears to be a stagnant body of water, it flows west anddischargesinto the Rumford River [ref. 6; 16, p. 3- 6]. At one time, catch basins located throughout the property discharged stormwater runoff to the Rumford River; however, during the on -site reconnaissance, START personnel noted that the catchbasins were clogged with debris [ref. 6, p. 41. See Figure 4 of this documentation record for an illustration of these surface water bodies. The Rumford River flows southward through Fulton Pond, Kingman Pond, and Cabot Pond, and into the Norton Reservoir [ref. 3; 49, Figure 4]. On the southeast side of Norton Reservoir, the Rumford, River continues to flow southward, and is called Threemile River, approximately 7.4 miles downstream of the probably point of entry (PPE) (ref. 3). Surface water continues to flow south for approximately 7.6 miles to the end of the 15-mile surface vyater TDL located on the Threemile River, approximately 0.3 mile downstream of Route 44 in Taunton, Massachusetts [ref. 49, Figure 5]. PPEs The surface water pathway PPEs are shown on Figure 4 of this documentation record. The most upstream PPE to surface water (referred to in this documentation record as PPE -I) is located approximately 300 feet upstream of the confluence of the two branches of the Rumford River immediately after they enter the HPC facility just southwest of County Street [ref. 8, Figure 1-2). PPE-2 is on the main (east) branch of the Rumford River that flows from the Glue Factory Pond, while PPE-1 is on the western branch. PPE -I and PPE-2 are located along the northern border of Source 1 [ref. 8, Figures 1-2 and 3-1; 49, Figure 2; and 53, Figure 21. It is approximately 1,500 feet (in the downstream direction) from PPE-1 totheconfluence of the Rumford River and the Rumford River backwash channel [ref. 8, Figure 1-2]. Another upstream PPE (PPE-3) is located along the wetlands surrounding the Rumford River backwash channel, approximately 1,500 feet upstream of its confluence with the Rumford River near the eastern edge of Source 2 [ref. 8, Figure 1�21. PPE-3 is located within the palustrine forested wetlands at the most upstream point likely to be impacted by Source 2 [ref. 8, Figure 1-2]. The farthest downstream PPE (PPE-4) is located just downstream from the confluence of the Rumford River and the Rumford River backwash channel. PPE-4 is the most downstream point likely to be impacted by Source 2 and is near the ground water treatment area. Many other PPEs exist between PPE-1 and PPE-4 along the Rumford River; the Rumford River backwash channel and the wetlands, where runoff from source areas is likely to enter these surface water bodies [ref. 3; 8, Figure 1-2]. The distance between PPE-1 (the farthest upstream PPE) and PPE-4 (the farthest downstream PPE) is approximately 1,500 feet [refs. 3; 8, Figure 1-2]. Although the surface water pathway HRS score is based on the overland flow/flood component of the surface water pathway, another significant contaminant migration path to the Rumford River is via ground water recharge [refs. 8, Figure 1-2; 49, p. 32, Figure 21. Rumford River Flow Near the HPC site, the course of the Rumford River has been altered several times in the past. Prior to 1850, the river allegedly flowed west to east through the former operations area of the HPC property before cutting toward the south between the current location of the Mill Building and the Cylinders No.I and 2 building [ref. 8, p. 3-5]. In 1850, to permit construction of the railroad tracks, the river was rerouted to flow to the Rumford River backwash channel. The Rumford River flow was altered to its present course, between 1945 and 1950, to allow for the construction of a major highway underpass [ref. 8, p. 3-5]. MADEP has reported that contaminants flow through the filled former riverbed sediments as evidenced by seep outbreaks observed along south-central property areas and historical outbreaks of tar mats along the Rumford River by former riverbed flow paths [refs. 7, Figure 2a, p. 7; 8, Figure 3-6]. July 2001 37 SW -General No USGS gaging stations are located along the surface water target distance limit; the flow rates are estimated for the various portions of the surface water within the 15 mile TDL. The flow rate reaches 100 cfs approximately 11.5 miles downstream of PPE-4. At several points along the TDL, the flow rate of the Rumford River was estimated using the USGS conversion factor of 1.8 cfs per square mile of drainage basin [refs. 3; 28; 29; and 30]. Approximately 7.4 miles downstream of the PPE-4, the drainage basin area is 22.3 mi'; the Rumford River at this point is estimated to flow at 40.1 cfs. Approximately 14.7 miles downstream of PPE-4, the drainage basin of the Threemile River is approximately 81.4 mi'; the flow rate at this point (near route 44) is estimated at 146.5 cfs [refs. 28; 29; and 30). Field observations indicate that the Rumford River backwash channel flow is less than 10 cfs [ref. 6); however, the HPC Phase 11 Site Assessment estimated that the flow of the Rumford River at the site is approximately 11.6 cfs [ref. 16, p. 3-6]. 4.1.2.1 Likelihood of Release 4.1.2.1.1 Observed Release Direct Observation - Basis for Direct Observation: Hazardous substances released from the HPC site have caused adverse effects to fish in the Rumford River, and also to the fishery. Tissue samples from fish caught downstream from the HPC site are contaminated with dioxins and furans released from the HPC site. In response to the fish contamination, the State of Massachusetts has closed the fishery, warning anglers not to eat fish caught in the Rumford River downstream of the HPC site [refs. 55; 57].

In October 1998, EPA's Removal Branch collected 12 sediment and five surface water samples from the Rumford River [ref. 49, p. 371. These sampling event results are summarized in the December 1999 HPC SI [ref. 49] and the validated data are presented in References 38 and 40. In September 1999, EPA's Removal Branch again collected samples from the Rumford River, this time upstream of the UPC site in and near the Glue Factory Pond [ref. 341. Four sediment and seven fish tissue samples were collected as part of this effort and analyzed for PCP, dioxins, and furans [refs. 34; 33; 14]. Because three of these sediment samples were collected upstream of the HPC site, they are used to further establish background levels for these hazardous substances [ref. 34, Figure 2]. These sampling events documented an observed release by chemical July 2001 39 SW -Likelihood of Release analysis of various dioxins, furans and PCP. Sediment and surface water samples collected by HPC are also presented following these EPA results and further document the observed release to surface water by chemical analysis. - Background Samples for 1998/1999 EPA Removal Program Sampling [ref. 38; 40; 49; 34; 33; 14]: Sample Sample Location Sample ID Medium Depth Date Reference RRUS-S sediment north of County Rd Surface 10/16/98 38; 40, Data Tables; 49, Figure 4, pp. 37-38 RRUS-2S sediment north of County Rd Surface 10/16/98 38; 40, Data Tables; 49, Figure 4, pp. 37-38 GFPS sediment south bank of Glue 0-3" 9/29/99 34, p.

These samples were analyzed for dioxins and furans using EPA Method 1613A [refs. 51, Jr. 24; 54, p. 11. The results revealed high concentrations of dioxinsandfurans in both surface water and sediment [refs. 51, pp. 8 and 9; 54, pp. 4, 5, and 6]. These results corroborate the EPA sediment and surface water sampling conducted four months later in October 1998 (see results above). Attribution The substances detected in surface water are attributable to the IIPC site. They are found in sources at the site, which were not contained against a release to surface water [see sections 2.2.2 for Sources I and 2]. The substances detected in the observed release by chemical analysis consist of either the constituents of wood preserving materials used at the site or substances created by the transformation of constituents used at the site [ref. 16, p. 1-2]. From 1953 to 1993, HPC preserved wood products using a number of chemicals, including: PCP in fuel oil, creosote, FCAP salts in water, and chromated-copper-arsenate salts in water [ref. 16, pp. 1-1, 1-2]. The wood products treated at HPC were allowed to drip onto the ground or onto concrete drip pads that were found to be riddled with cracks, gaps, and corroded areas during a RCRA inspection [ref. 7, p. 8]. The former General Manager and President of HPC (from 1973 to 1993) stated in sworn testimony that PCP, CCA, and other wood treating products were allowed to drip onto bare soil throughout the entire site [ref. 44, pp. 30, 32, 61]. -HPC's Phase II report concludes that PCP attributable to the site is present in surface water samples collected from the Rumford River backwash at levels below the proposed (at that time) EPA standard drinking water levels [ref. 16, pp. 2-6, 2-19]. HPC also stated that the ground water contamination plume extends within the Rumford River backwash channel area [ref. 16, p. 2-20). In addition, the ground water well closest to the Rumford River and the Rumford River backwash channel (MW-10) has consistently shown contamination (including PCP and PAHs) attributable to the UPC site, indicating contaminant migration toward, and into, surface water [ref. 16, Figure 2-17). In 1972, a tar mat was discovered on the banks of the Rumford River on the southern portion of the HPC property. It appeared to originate from the eastern bank of the Rumford River [refs. 4, p. 8; 7, p. 7; 8, p. 1-2; 16, p. 2-11. FIPC took efforts to control the seep but in 1973, seepage appeared again farther downstream [ref. 16, p. 2-1]. According to HPC's consultant Keystone, vandals shot holes in several drums of recovered oil that were stored on the HPC property along the east bank of the Rumford River and then tipped the drums over, allowing the oils to seep into the ground and the river [ref. 16, Jr. 2-3]. In 1990, after "oily seepage" was again reported on the Rumford River in the vicinity of the HPC property, Keystone sampled stained soil along the river bank and found that a major constituent of the contamination was SVOCs [refs. 7, p. 7; 17, p. 2-7]. Dioxins and furans are commonly associated with chlorophenolic compounds used in wood preserving and are present in contaminated soil on site [ref. 48, pp. 3-7, 2-8, and 4-22]. Dioxins occur as contaminants in the manufacturing process of certain chlorinated organic products such as PCP [ref. 46, pp. 3 and 8], In addition to their presence as contaminants in wood treating products, dioxins and furans can be produced by the combustion of wood treated with PCP and other chlorinated phenols [ref. 46, p. 3]. Finally, the State of Massachusetts issued a health advisory not to eat fish in the Rumford River downstream of the UPC site to Kingman Pond in 1999 [ref. 55]. This advisory, in conjunction with the ATSDR Health Consultation upon which the advisory is based, both attribute the dioxin, furan and PCP contamination in soil, ground water, surface water, sediment and fish tissue to the HPC site [refs. 55; 57, pp. 1, 2, 3]. The State's closure of the fishery due to dioxin contamination is directly attributed to UPC alone [refs. 51; 54; 55; 57]. In addition, the only other possible sources of dioxin and furan contamination are a former bleachery located upstream of the site near the Glue Factory Pond [refs. 3; 16; 34] and the Porter Estate , which received various unauthorized wastes including wastes from HPC [ref. 13, p. I]. Surface drainage runoff from both of these sites drains to the main branch of the Rumford River. Background samples sediment samples RRUS-S and RR1LJS-2S collected just upstream from the UPC site are located on this branch of the Rumford River and, therefore, account for any upstream contamination. Sediment samples GFPS, GFPN, and RRB, collected as part of the Glue Factory Pond investigation, are also used to establish background levels to account for any possible contamination originating at the former bleachery or the Porter Estate sites. In addition, EPA's removal branch collected seven fish tissue samples from the Glue Factory Pond [ref. 34, Table 1]. No dioxins, furans, or PCP were detected in any of these seven fish tissue samples, further proving that the dioxin, furan, and PCP contamination is originating, at least in part, from HPC [ref. 15]. Background surface water and sediment samples account for any migration from this possible upstream source (see section 4.1.2.1.1 of this documentation record).

Fulton Pond is a seven -acre impoundment with depths to 25 feet managed as a catchable trout pond and annually stocked with brook, brown, and rainbow trout, but also contains yellow perch, bluegill, largemouth bass, white sucker, white perch,. pumpkinseed, brown bullhead, golden shiner, black crappie, redfin pickerel, American eel, and chain pickerel [Ref. 35]. According to historical records, the Rumford River was also stocked at one time by HPC [Ref. 35]. The Rumford River is also a fishery and contains brook and rainbow trout and warm water species such as largemouth bass, chain pickerel, pumpkinseed sunfish, white and yellow perch, black crappie, and bluegill [Ref. 35].

B-16 16, Table 2-6 In October 1998, the State of Massachusetts Department of Public Health (MDPH) issued a Provisional Public Health Fish Consumption Advisory for the Rumford River and associated impoundments, i.e., Fulton, Kingman, and Cabot ponds and the Norton Reservior [ref. 561. The reason for issuing the provisional advisory is that "[d]ioxin compounds have been identified in surface water near the former Hatheway and Patterson sites in Mansfield." A provisional advisory was issued because it was not feasible at the time to obtain fish tissue sampling data in a timely way because of the limited availability of laboratory resources nationwide for these analytes and the technical requirements involved in the analysis. The MDPH felt that it was a "proactive and prudent public health measure to issue a provisional advisory without waiting for results of fish tissue sampling." [ref. 56). Following the U.S. EPA's October 1998 sampling and analysis of sediment, surface water (see observed release section above), and fish tissue samples, the MDPH, under cooperative agreement with ATSDR, issued a Health Consultation for the Rumford River Site [ref. 57]. The conclusions stated that "[t]he concentrations of dioxin in fish in the Rumford River below Glue Factory Pond to and including Norton Reservoir constitute a public health hazard. Therefore, based on these data and information about the HP [Hatheway and Patterson] site, a regular public health fish consumption advisory should be issued by MDPH in follow-up to the provisional advisory issued by MDPH in October 1998." [ref._ 57]. On June 30, 1999, the MDPH issued a regular public health fish consumption advisory [ref. 55; 47]. This updated fish advisory recommends that "[a]Il persons should refrain from consuming any fish caught in the Rumford River, downstream of Glue Factory Pond, Fulton Pond, Kingman Pond, Cabot Pond, or Norton Reservoir." [ref. 47) The advisory attributes the dioxin contamination to the HPC site (ref. 47). This fishery closure is therefore attributed to releases of hazardous substances at the HPC site and in the observed release by chemical analysis of sediment and surface water samples. - Level I Concentrations Seven fish tissue samples were collected from Fulton Pond (FPFISH001, FPFISH002, FPFISH003, FPFISH004, FPFISH005, FPFISH006, and FPFISH007) [ref. 57, p. 3]. These fish tissue samples were analyzed for dioxins/furans (EPA Method 1613B), pentachlorophenol, and inorganic arsenic [refs. 42; 43]. Although PCP was detected in each fish tissue sample, the concentrations detected were below the CRQL [ref. 42). Dioxins and furans were detected in each of the seven fish tissue samples. Those meeting Level I concentrations are listed below [refs. 2, pp. B-53, B-60; 43].

Wetlands PPE-3 is located on the northern boundary of the palustrine wetland that surrounds the Rumford River and the Rumford River backwash channel (see Figure 4 of this documentation record). This wetland is shown on the U.S. Fish and Wildlife Service National Wetland Inventory (NWI) map for the Mansfield quadrangle as "PFOI," or palustrine forested, broad-leaved deciduous [ref. 11). The length of this wetland is determined for HRS scoring purposes by measuring the perimeter of this entire wetland to the point downstream where the Rumford River exits the wetland as shown on the NWI map. This perimeter is approximately 1.25 miles in length [Ref. 11]. This yields an assigned wetlands value of 50 from table 4-24 of the HRS [Ref. 1). Because surface water sample RRKP-W is located downstream of this wetland, the entire wetland is scored as Level 1I.

News ContactsTarnela Harting-13arrat, Office of Community Affairs, 617-918-1318 For immediate release: October 1, 2001 EPA TO HOLD OPEN HOUSE AND INFORMATIONAL MEETING TO DISCUSS THE PROPOSED HATHEWAX & PATTERSON SUPERFUND SITE Boston- The U.S. Environmental Protection Agency is hosting a public information meeting on Thursday, October 181h at 7.00 pm at the Mansfield Town Hall to discuss the current status and future clean-up activities at the proposed Hatheway & Patterson Superfand Site, The site is located at 15 County Street in Mansfield, MA. The Hatheway & Patterson site was proposed for inclusion on the National Priorities List (NPL or Superfund) in September of 2001. The NPL is EPA's list of the of the country's most serious hazardous waste sites identified for possible long- term cleanup. The Superfund program makes public funds available to clean up listed toxic waste sites when private financing is unavailable. The proposed Hatheway & Patterson Superfund Site is a 40 acre site, bisected by the Rumford River and a Consolidated Railways rail line, From 1953 to 1993, the company used the site to treat wood using solutions ofpentachlorophenol (PCP) in fuel oil, and fluorochrome-arsenate-phenol salts in water as well as chromated copper -arsenate (CCA) salts in water. Prior to utilizing the pressure treatment process, Hatheway & Patterson allowed wood -treating chemicals to drip off treated lumber onto underlying soils, This practice caused surface soils to be contaminated with copper, chronumn, arsenic and PCP in various areas of the site. The company ceased operations in April 1993 after having filed for bankruptcy in February 1993. VISIT EPA's WEB SITE HOME PAGE FOR NEWS AND INFORMATION: http://www.epa.goy/regionol
