U.S. Environmental Protection Agency Region 3
Havertown PCP Superfund Site
Havertown Township, Delaware County, Pennsylvania
August 2007
EPA Recommends Proposed Remedy
The U.S. Environmental Protection Agency (EPA) continues to clean up contamination at the
Havertown PCP Superfund Site (the "Site"), which is located in Havertown Township, Delaware
County, Pennsylvania. EPA has developed a Proposed Remedial Action Plan (Proposed Plan) for
the third and final Operable Unit (OU) for the Site. OU3 has been divided into two separate units,
OU3A and OU3B. OU3A addresses the deep groundwater in the source area and OU3B addresses
the contaminated soil and groundwater in the Recreational and Open Space (ROS) area, which is
located behind Rittenhouse Circle and adjacent to Washington Avenue in Havertown.
The Proposed Plan identifies EPA's preferred alternative for cleaning up the contamination of OU3,
and explains the rationale for this preference. In addition, the Proposed Plan includes summaries of
other cleanup alternatives evaluated for use at the Site.

Proposed Plan Overview
EPA's preferred cleanup remedy for
OU3A - deep groundwater in the source
area - is Alternative 3A. This cleanup
alternative (remedy) includes:
>	Groundwater containment:
•	Installing an additional
recovery well to enhance
performance of the current
groundwater remediation
system;
•	Upgrading/retrofitting the
existing groundwater
remediation plant to increase
its treatment capacity.
>	In-situ chemical enhanced flushing:
•	Injecting an aqueous solution
into a zone with contaminated
soil and groundwater;
•	Extracting groundwater and
injected fluids downgradient of
the injection point;
•	Treating the extracted water
above-ground;
•	Discharging or re-injecting the
treated water.
EPA's preferred cleanup remedy for OU3B
- the ROS area - is Alternative 4B. This
cleanup remedy includes:
>	Excavating an area about 50 ft. by 50 ft.
in the ROS area, and a narrow zone
along the abandoned sewer line (about
200 ft. long by 20 ft. wide);
>	Removing the portion of the abandoned
sewer that is not sealed with grout;
>	Backfilling the excavated area with
clean soil and re-vegetating it;
>	Installing three extraction wells, which
will extract contaminated groundwater
and transport it to the current
groundwater remediation facility;
>	Establishing institutional controls to
ensure that the engineered remedy will
not be compromised.
The final remedy for cleaning up OU3 at
the Site will be selected after the 30-day
Public Comment Period. The public is
encouraged to review and comment on all
of the alternatives presented in the
Proposed Plan. EPA will hold a Public
Meeting to explain the Proposed Plan and
the preferred remedy. Oral and written
comments will be accepted at the meeting.
Comments may also be submitted by e-
mail or regular mail, postmarked by
midnight on September 21, 2007.

Site History
The Site is located approximately 10 miles west of Philadelphia and is surrounded by a mixture
of commercial establishments, industries, parks, schools, and private residences. The Site covers
approximately 12 to 15 acres with no distinct boundaries. It is roughly bordered by Lawrence
Road and Rittenhouse Circle to the south, the former Penn Central Railroad tracks to the north,
the fence line of the Continental Motors property to the west, and Naylors Run to the east.
The Site was occupied by National Wood Preservers (NWP) in 1947. Treatment of wood
products was the main practice. During the period from 1947 to 1963, NWP allegedly disposed
of waste materials, such as diesel-type oil and pentacholorophenol (PCP) in a well. The exact
location of the well has not been identified.
The Proposed Plan discussed above is for the final OU for the Site. The Site was divided into
three OUs. 0U1 included the installation of an oil-water separator as an interim remedy. The
separator was installed in 1991 to reduce the oil in the storm sewer discharging to Naylors Run.
Removal and disposal of the on-site containerized wastes at the NWP Site was also performed.
0U2 included the implementation of an on-site pump and treat system, together with a
groundwater collection trench and recovery wells. This was an interim remedy to address the
shallow groundwater aquifer in the source area of the Site. In addition, during the 1992
investigation, soil at the NWP facility was found to be contaminated with arsenic and dioxins.
Accordingly, EPA implemented a "Removal Action" in 1998. The waste soils from the NWP
facility were capped in place.
