- The EPA is currently conducting a Remedial Investigation and Feasibility Study (RI/FS) to determine the nature and extent of contamination, and the best way to go about cleaning up the site.
- The EPA completed an initial round of the Remedial Investigation in 2008, which determined the presence of Volatile Organic Chemicals (VOCs) in the groundwater.
- Home wells identified as having high concentrations of VOCs related to the site were installed with carbon filtration systems. Those systems continue to be monitored and are sampled quarterly by the EPA.
- For additional information about VOCs and vapor intrusion, see the Contaminants and Risks section.
- Additional information is still needed to fully characterize the site and EPA is exploring all available options to complete the final RI/FS.
- The Old Wilmington Road Groundwater Contamination site is an area where groundwater is contaminated with various volatile organic compounds (VOCs) located in the vicinity of Old Wilmington Road in West Caln Township, Pennsylvania.
- The groundwater contamination was discovered during an EPA Site Inspection (SI) completed for the Perry Phillips Landfill site located along Old Wilmington Road.
- During the investigation, 11 home wells were sampled. Laboratory results indicated that a home well located on the site and other wells in the vicinity were contaminated with VOCs and manganese at significantly high levels.
- A well that provided water to the 60 residents of a private mobile home park was found to be contaminated with elevated levels of trichloroethane (TCE).
- EPA also completed an initial vapor intrusion study at the site in 2010.
NPL Listing History
- This site is currently in the Remedial Investigation and Feasibility Study phase.
- EPA provided and maintains carbon filtration systems on residential wells that have contamination at levels of concern.
- In addition, EPA will continue to monitor those wells and several other residential wells in the area.
- Based on the results of a 1993 site assessment, EPA determined that there was an immediate and significant threat to human health caused by elevated concentrations of VOCs in the drinking water supplies of residents living in the vicinity of the Perry Phillips Landfill Site. VOCs are contaminants dissolved in liquids like groundwater that have the potential to turn into gasses.
- Three areas of high VOC concentrations were identified during a soil gas survey completed in the area by EPA in 1994 – two areas were on the Perry Landfill site, and the other was on an adjacent property.
- Due to the high VOC concentrations, EPA conducted an initial vapor intrusion study in 2010. For additional information about vapor intrusion, please check out, What You Should Know About Vapor Intrusion (PDF) (2 pp, 88.5K).
- Contaminant descriptions and associated risk factors are available at: (ATSDR web site).
