Current Site Status
The U.S. Environmental Protection Agency is overseeing the cleanup of the Shriver's Corner site. The cleanup is being carried out by the Westinghouse Company, the potentially responsible party (PRP). Currently, the site does not pose any immediate public health risk. All area residents have been provided with safe drinking water, thanks to water filters and a new community well which four homes were connected to in February 2000.
The next step in the cleanup process is to clean the groundwater. All testing wells have been installed for the groundwater cleanup. A system built to pump and treat the groundwater was completed in the end of 2002. That same year, long-term groundwater cleanup began and will continue for more than 30 years. Soil cleanup at the Shealer Area and Culp Area was completed in August 1999.
The PRP has voluntarily conducted a screening process to investigate exposure pathways due to vapor intrusion (VI). PRP submitted VI assessment report in August 2005. The report findings indicated that there were no VI exposure threats to the near by homes. The first Five Year Review of the site was completed on August 8, of 2008 The Five Year review found the Site to be protective in short term and the remedy is expected to be fully protective of human health and the environment upon attainment of groundwater cleanup goals. In November 2012, second Five Year Review was initiated. The Site inspection was done on February 2013 and local residents and the Straban Township supervisor were interviewed about the Site.
The Shriver's Corner site has two areas covering about 10 acres located south of Route 394 (Shriver's Corner Road), in Straban Township, Adams County. Both areas have accepted drums of wastes from the Westinghouse Elevator Plant, a Superfund Site in Cumberland Township. Drums containing volatile organic compounds (VOCs) which are chemical components of solvents, liquid wastes, and paint sludge reportedly were dumped at the southern edge of the property.
Approximately 5,000 people use wells within three miles of the site as a source of drinking water. Approximately 250 people live within a mile of the site; the nearest residence is 100 feet away, and the nearest well is 10 feet from the site. The groundwater is contaminated with VOCs including chlorinated solvents, toluene, and xylene from former waste disposal practices.
Site ResponsibilityThis site is the responsibility of federal and state governments, the site owner and parties potentially responsible for site contamination.
NPL Listing HistoryOur 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 NPL on October 15, 1984 and formally added to the list on June 10, 1986.
Threats and ContaminantsThe groundwater is contaminated with VOCs including chlorinated solvents, toluene, and xylene from former waste disposal practices. Threats to the public include drinking contaminated well water and coming into direct contact with any remaining contaminated wastes left on the site. Westinghouse has provided carbon filters for affected residential wells in the area, and drilled a new community well.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
In April 1985, EPA ordered Westinghouse to remove about 80 surface drums and 250 cubic yards of contaminated soils and send the materials to an EPA-approved disposal site. A two-inch soil cover was placed over a contaminated area of the site. The company also provided carbon filters for some residential wells. These measures eliminated the immediate threats to the affected public and are controlling further site contamination. In 1995, after failed negotiations with PRPs, EPA built an eight-foot chain link fence to prevent nearby residents, including children, from coming in contact with newly discovered dangerous chemicals.
Under EPA supervision, Westinghouse finished the all studies of the groundwater and soil. These studies identify contamination types, locations, and concentrations. They also recommend a variety of approaches to dealing with the site pollution. On June 20, 1995, EPA released its proposed plan which explains the cleanup method chosen for the site. EPA's decision is formally described in a legal document (Record of Decision, or, ROD) that was issued on September 29, 1995. EPA's decision involves: 1) building a community well to supply water to affected homes, 2) removing approximately 1,800 cubic yards of soil contaminated with heavy metals, such as lead, 3) capping the excavated area, 4) extracting heavily contaminated groundwater, and 5) removing approximately 220 cubic yards of contaminated sediments.
The plans for the groundwater cleanup are finished, and PRPs are starting to do the work that is needed. Groundwater sampling done in February 1999 showed that the water pollution is moving as predicted -- slowly, heading downhill toward the westward creek. The path of this pollution movement will not impact any water supplies.
The soil cleanup at the Shealer Area and Culp Area was finished in August 1999. The community well was drilled and tested; affected residences were connected to it in February 2000. Installation of test wells for the groundwater pump and treat design was completed in the fall of 2001. A total of forty-nine groundwater monitoring wells and six recovery wells were installed during the design of the groundwater cleanup. In October 2002, the groundwater treatment system was constructed and completed. All the construction activities for Site cleanup were successfully completed. EPA issued a Preliminary Close Out Report (PCOR) on January 7, 2003. The groundwater treatment system is fully functional and operating successfully. The system will need to operate many years to restore the groundwater to drinking standard.
PRP has voluntarily conducted screeing process to investigate exposure pathways due to vapor intrusion. A report on finding was submitted to EPA in August 2005 and it is under EPA review. PRP submitted VI assessment report in August 2005. The report findings indicated that there were no VI exposure threats to the near by homes. The first Five Year Review of the site was completed on August 8, of 2008 The Five Year review found the Site to be protective in short term and the remedy is expected to be fully protective of human health and the environment upon attainment of groundwater cleanup goals. In November 2012, second Five Year Review was initiated. The Site inspection was done on February 2013 and local residents and the Straban Township supervisor were interviewed about the Site.
