The North Penn – Area 6 site is located in and around the Borough of Landsdale in Montgomery County, Pennsylvania. The site is largely a groundwater contamination problem. Trichloroethene (TCE) and perchloroethene (PCE), the chemical components of solvents and degreasers, are the primary contaminants in the groundwater, although several other contaminants are present. Twenty-six facilities in the Lansdale area were originally identified as possible sources of contamination due to their use of site-related solvents. Groundwater cleanup is ongoing at some of the facilities. Design work for remedy implementation at the other facilities is ongoing.
What Is Being Done to Clean Up the Site?
The site is being addressed through federal, state and PRP actions.
Since site discovery, about 20 homes have been connected to public water supplies. Beginning in the fall of 2004, EPA sampled private wells for site-related contaminants. Additional private wells were found to be impacted and PRPs will be offering connections to those well users pursuant to the site’s May 2005 Consent Decree.
In addition to groundwater contamination, there are also properties with contaminated soil. EPA removed contaminated soil from Keystone Hydraulics, Rogers Mechanical and Electra Products. Site restoration activities are complete. A fourth property owner, John Evans and Son, conducted a soil cleanup in 2003, under EPA oversight.
Presently, two PRPs are conducting studies to determine if soil cleanup is necessary at their properties. These properties are the former Parker Hannifin company at 422 West 6th Street and J.W. Rex at 8th & Valley Forge Road.
EPA transitioned operation and maintenance of the treatment systems at the Keystone Hydraulics and Royal Cleaners properties to the Pennsylvania Department of Environmental Protection (PADEP) in February 2014.
What Is the Current Site Status?
The long-term remedy for groundwater, selected in a 2000 Record of Decision (ROD), included groundwater extraction and treatment, and connection of affected residences and businesses to the public water supply. EPA completed construction of five groundwater extraction and treatment systems at separate properties within the site (the former Keystone Hydraulics at 834 West Third Street, Royal Cleaners at 1315 North Broad Street, Westside Industries at 5th & Mitchell Streets., the former Electra Products at 200 West Fifth Street and the former Rogers Mechanical Company at 135 East Hancock Street). Construction of the most recent system at the former Rogers Mechanical Company finished in May 2011.
EPA has reached agreement with the following parties for work related to groundwater contamination: the John Evans Property at Maple & Spring, the Parker Hannifin Corporation at 422 West 6th Street, the J.W. Rex Heat Treat property at 8th & Valley Forge Road and Tyco International at 451 North Cannon Ave. A remedial design for the J.W. Rex property has been completed and a groundwater extraction system currently operates on the property. The remaining potentially responsible party (PRP)-lead properties are in the remedial design phase.
During cleanup, a site can be divided into a number of distinct areas depending on its complexity. These areas, called operable units (OUs), may address geographic areas, specific problems, or areas where a specific action is required. Examples of typical operable units include construction of a groundwater pump and treatment system or construction of a cap over a landfill.
