THE

WATSON JOHNSON LANDFILL

SUPERFUND SITE

U.S. EPA Region 3 January 2015


-------
Site History

Contaminants Of Concern

	The Watson Johnson Landfill Superfund
Site is a former landfill on East Pumping
Station Road in Richland Township,
Bucks County, Pennsylvania. The entire
property consists of approximately 56
acres, of which approximately 32
acres were used as a landfill. The por-
tion of the site that was used as a
landfill was active from the late 1950s
until the early 1970s. The landfill ac-
cepted both industrial and municipal
wastes

	In June 1998, concerned citizens con-
tacted the U.S. Environmental Protec-
tion Agency (EPA) and requested that
the agency do an investigation of the
former landfill. EPA conducted field
investigations at the site from 1998
through 1999, collecting samples from
on-site soils, adjacent wetlands, To-
hickon Creek and groundwater moni-
toring wells. Local residential and
Quakertown Borough municipal wells
were also sampled. The results from
these tests determined that the former
landfill was a potential threat to
human health and the environment

	On September 13, 2001 the EPA listed
the former landfill on the National Pri-
orities List (NPL). When a Site is listed on
the NPL it is eligible for federal cleanup
money. Sites on the NPL are referred
to as Superfund Sites

Samples from the on-site soils, adjacent
wetlands, Tohickon Creek and groundwa
ter monitoring wells detected the follow-
ing hazardous substances:

	Volatile organic compounds
(VOCs)

	Semi-volatile organic compounds
(SVOCs)

	Polychiorinated biphenols (PCBs)

	Metals

	Perchloroethene (PCEj

	Trichloroethene (TCE)

Descriptions of the contaminants and risk
factors can be found at:

Please feel free to confacf us at anytime.
We are happy to answer any questions
you may have.

Cleanup Progress

Next Steps

A Quakertown Borough drinking water
supply well, down gradient from the
Site, is equipped with an air stripper to
remove any VOC contamination.

In 1999 a drum found on site revealed
high levels of PCE and lead. EPA re-
moved the drum and the surrounding
contaminated soil in 2000

Approximately 35 residential wells af-
fected and/or potentially affected by
TCE contaminated groundwater, were
connected to the public water main.
This was completed in 2006

EPA continues to monitor groundwater

The above image, taken in November 2014,
shows waste still present on the former landfill.

Construction for the cleanup remedy is

due to begin in 2015.

The cleanup will include:

1.	A multi-layer cap for the landfill

	All waste located outside the landfill
will be removed or put below the cap

	The landfill will be vegetated, and
landscaping will be designed around
the Site

	The cap will prevent exposure to all
landfill contaminants

	A drainage system for the landfill wiil
be installed

2.	Groundwater cleanup

	Installation of injection wells to treat the
contamination

	Installation of additional monitoring
wells to monitor cleanup effectiveness
