Progress Report for July 1993
Dear Mr. Boelitz:
This progress report is intended to update the Department on the activities involved in
the performance of the Supplemental Phase II Comprehensive Site Assessment and
the Interim Measure assessment being conducted by Penney Engineering at the
Hatheway & Patterson site.
Interim Measure Assessment
In order to obtain groundwater elevation data within the wetlands on the southern
portion of the site, two additional observation wells (OW-13 and OW-14) were installed
on July 30. As reported in our June progress report, the observation wells OW-1
through OW-7, previously installed to depths of approximately two feet in the wetlands
were dry when gauged on July 21. The two additional wells were installed to a depth of
four feet below grade and into the groundwater.
The wells were composed of five-foot lengths of six-inch diameter, perforated PVC
drain pipe and were installed by hand with the aid of a post hole digging tool. The
locations of the wells will be plotted on the Interim Measure Plan which will be
submitted with the Interim Measure Design Report upon completion.
The vertical elevations of the two newly installed wells were surveyed on July 30. The
wells were allowed to equilibrate and were gauged on the morning of August 2. The
results of the survey and gauging activities are presented in Table 1 below.

Supplemental Phase II Activities
As discussed in our August 5, 1993 letter to Mark Begley, Chief of DEP-SERO's Site
Remediation Section, Penney has been attempting to establish a consistent payment
program in order to continue our work at the Hatheway & Patterson site. In the
meantime, we are only conducting work tasks that are critical to maintaining the health
and safety of the public and the environment. We anticipate that work on the
Supplemental Phase II project will resume in early September. We will advise the
Department if such a payment arrangement cannot be reached, thereby forcing us to
suspend all work at the site.
We will continue to keep the Department informed of the progress of the Supplemental
Phase II assessment and the proposed Interim Measure activities. Please call if you
have any questions.
Yours truly,
