DEP Site No. 4-0571 Progress Report Dear Mr. Boelitz: As you are aware, Hatheway and Patterson Company, Inc. has filed for bankruptcy and terminated its operations at their 15 County Street, Mansfield facility. The owners of the facility remain committed to fulfilling their obligations regarding the assessment and ultimately, the cleanup of the site. Penney Engineering, Inc has been retained by Hatheway and Patterson, as the debtor in possession, to continue to operate and maintain the existing Short Term Measure, proceed with the approved Proposed Interim Measure test pitting program, and to complete the supplemental Phase II - Comprehensive Site Assessment tasks for the site. Penney has been approved by the Bankruptcy Court to provide these services on a continued basis. The remainder of this progress report will summarize our activities at the site for the month of April. We have initiated a new reporting program to include sending copies of our reports to the Mansfield Board of Health. The monthly monitoring reports for the Short Term Measure (STM) will continue to be sent to you and the Mansfield Wastewater Treatment Plant. Interim Measure Proposal Status We are awaiting authorization from the bankruptcy attorney and court to proceed with the test pitting program for the approved Proposed Interim Measure. We are tentatively scheduled to begin the week of June 7. We will call your office in advance to inform you of the exact date so that you may arrange to be present. 125 High Street, Mansfield, MA 02048 (508) 261-1288 FAX (508) 261-1208 Recycled Paper Mr. Boelitz May 27, 1993 Page 2 A program of weekly bailing of free -phase oil from wells MW-6 and MW-12 was implemented in December, 1992. This program will continue until the completion of the Interim Measure which is intended to address the oil in the wells. The dates and quantities of oil recovered from the wells since our last update, measured by the thickness of the oil layer within each well, are summarized in Table 1. Table 1 Oil Measured (inches) Date MW-6 MW-12 3/19/93 film film 3/26/93 film 0.1 4/2/93 sheen film 4/9/93 sheen film 4/16/93 film 0.2 4/23/93 film 0.2 4/30/93 sheen 0.2 5/7/93 sheen 0.1 5/ 14/93 0.0 0.1 5/21 /93 0.0 film A breakout of free -phase oil to the wetlands south of well MW-12 was detected on March 29, during a weekly inspection of the area. Approximately 0.1 inch of oil was observed on the surface of the standing water within the same area previously described by the December, 1992 breakout. Absorbent pads were placed in the wetlands in order to recover the oil and prevent further migration. The Department was immediately notified of the condition and a site inspection was attended by you, Mr. Paul Vigeant, Mr. William Haynes, and Mr. Scott Leite on March 30, 1993. Our February 23, 1993 Interim Measure Proposal approved by the Department is intended to abate the breakout of oil to the wetlands. Phase II Comprehensive Site Assessment Progress Repairs were performed on two of the existing monitoring wells on May 4. A 12-inch, steel manhole was cemented into place around the top of well MW-1 to prevent the introduction of surface water to the well. The well is protected by a flush -mounted gate box which had been set lower than the surrounding ground surface. Also, a steel standpipe with a locking cap was installed over well MW-4 and cemented into place. The well was previously protected by a flush -mounted gate box which was set lower PENNEY ENGINEERING, INC Mr. Boelitz May 27, 1993 Page 3 than the surrounding ground surface, thereby providing the potential for the introduction of surface water into the well. An instrument survey has been performed in order to prepare a topography and groundwater contour plan. The plans will be used to evaluate the effectiveness of the existing STM and the final remedial measure for the site. On April 5, 1993 groundwater samples were collected from the top of the groundwater table at selected locations using a see -through plastic thief. The thief was decontaminated between sampling locations. The samples were inspected for the presence of free -phase oil in order to determine whether the high water table conditions, which were observed in early April, may have caused the release of oil from the subsurface contaminated soils into the groundwater. The locations sampled and the results of the sample inspections are presented in Table 2. The depths to groundwater were not measured, however, this information may be useful in the assessment of contaminant migration between soil and groundwater media.

The sampling event will include groundwater sampling and gauging from the 17 existing monitoring wells; surface water sampling from five stations along the Rumford River and backwash; and sediment samples from the bottom of the PENNEY ENGINEERING, INC Mr. Boelitz May 27, 1993 Page 4 Rumford River and backwash at four stations. The locations of all sampling stations are shown on the Site Plan which was included in our Monthly Progress Report dated February 10, 1993. (A copy is being sent to the Board of Health with this report.) Summary Penney Engineering continues to operate the existing groundwater treatment system defined as a Short Term Measure at the Hatheway and Patterson site. Since the shutdown of the facility, we have performed periodic inspections of the groundwater treatment system, and will continue to submit monthly monitoring reports. We will keep your office informed of the progress of our Phase II assessment and the Proposed Interim Measure activities. Please call us if you have any questions.
