EPA Region 3 (Mid-Atlantic)
EPA ID# PAD980830897
19th Congressional District
Last Update: January 2015
Current Site Status
- The Site has been determined to be protective of human health and the environment because direct exposure pathways have been eliminated by the implementation of the remedy.
- The exposure pathways that could result in unacceptable risks are being controlled. Institutional Controls (ICs) to prevent future use of the property have been implemented and are in place as required by the ROD.
- EPA completed the site inspection for the third five-year review on November 10, 2014. All components of the remedy are functioning appropriately.
- The third Five-Year Review report is scheduled to be issued by September 2015.
Site DescriptionLocated in Adams County, Pennsylvania, several local companies sent waste for disposal to this three-acre site from 1970 to 1980. Throughout its history, the disposal operation had no permit. The majority of the waste, consisting of paint sludge and various solvents, was dumped on the site grounds. There are several small streams on site. Approximately 9,500 people live in the area and use wells within three miles of the site for drinking water.
- Site Responsibility
- This site is being addressed through federal, state, and potentially responsible parties' actions.
- NPL Listing History
- Our country's most serious uncontrolled or abandoned hazardous waste sites can be cleaned using federal money. To be eligible for federal cleanup money, a site must be put on the National Priorities List (NPL). This site was proposed to the National Priorities List on October 15, 1984. The site was formally added to the list on June 10, 1986, making it eligible for federal cleanup funds.
Threats and ContaminantsThe groundwater and surface water are contaminated with volatile organic compounds (VOCs) from wastes dumped on site. Soils are polluted with heavy metals and asbestos. Possible health threats include accidentally ingesting or coming in direct contact with contaminated soils and drinking polluted water.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
In 1984, EPA issued an administrative order, requiring Westinghouse Electric (now Viacom) to excavate a waste lagoon and contaminated soil and transport these materials offsite for disposal at an approved facility. EPA built a fence around the lagoon area and sampled soil and water both on- and off-site in 1985. That same year, EPA and the Commonwealth of Pennsylvania signed a multi-site cooperative agreement that provided funds for an investigation into the nature and extent of contamination at the site.
In 1987, Westinghouse signed a consent order agreeing to do more work at the site. This work involved studying the pollution locations, volumes and types and also the options for addressing this pollution, tailored to this site. In 1988, Westinghouse signed another consent order to remove more buried drums and contaminated soil. The drums were removed In 1989 and the area was filled with clean soil. A water line supplies nearby residents with water from the municipal system.
In August 1993 of that year, EPA issued a Record of Decision (ROD), selecting the approaches for addressing all of the site pollution. This ROD details the pump-and-treat approach that will be used to clean the groundwater. It also describes the excavation and capping plan for polluted soils. Highly contaminated soils and sediments will be excavated and sent off-site for treatment/disposal. A soil cover will be installed over all of the contaminated areas. Wetlands will be replaced on-site.
After long negotiations, EPA and the PRPs were unable to reach agreement on the terms of a consent decree for doing the cleanup work and the designs needed for the cleanup. EPA decided to proceed with the designs, using the trust fund and the Army Corps of Engineers. As the Corps was performing the design work, the EPA negotiated an agreement with the PRPs to do the site cleanup themselves. The PRPs are now paying for the site design work, the construction, and the cleanup.
In addition to Viacom, the PRPs include: Pfaltzgraff, Dal-Tile, Spectra-Kote, Inland Container, and Fred Shealer. These PRPs, except for Fred Shealer, are sharing the costs at the site. The agreement reached with the PRPs also include the EPA in sharing a portion of the costs for the site cleanup as well.
Work started on the soil cleanup in August 2000. This work was completed in the summer of 2001 except for some wetlands restoration which was completed in the spring of 2002. The ground water pump and treat system portion of the remedy has also been completed in 2003. EPA issued a Preliminary Close Out Report (PCOR) on September 30, 2003. The Site has achieved construction completion status and the remedy is operating as designed. EPA approved the Interim Remedial Action Report for the Hunterstown Site on December 13, 2004. Institutional controls must still be implemented to protect the soil cover installed at the Site in addition to preventing ground water use.
PRP has voluntarily conducted screening process to investigate exposure pathways due to vapor intrusion. The PRP has voluntarily conducted a screening process to investigate exposure pathways due to vapor intrusion (VI). A report on the findings were submitted to EPA in August 2005. The report indicated potential for a vapor intrusion exposure pathway exited for one home near the Site.The first five-year review of the implemented remedy was completed in September 2005. The first five-year review findings were that impelemented remedy is human health protective in short term and will be fully protective once groundwater cleanup completed, The findings also pointed out that there is potential for VI exposure pathway for a home near the Site. During February 2006, a mitigation system was installed for the effected home to prevent exposure due to VI.
The second five-year review was completed in September 2010. The Site has been determined to be protective of human health and the environment because direct exposure pathways have been eliminated by the implementation of the remedy. The exposure pathways that could result in unacceptable risks are being controlled. All threats at the Site have been addressed through groundwater pump and treatment, off-site disposal of highly contaminated materials including soils and capping of the remaining contaminated soils which did not require off-site disposal based on RCRA criteria at the Site. Institutional Controls (ICs) to prevent future use of the property have been implemented and are in place as required by the ROD.
