Current Site Status
The Davis Park Road TCE site includes a residential and commercial area affected by contaminated ground water. EPA placed the site on the National Priorities List (NPL) in 1999 because of contaminated ground water. EPA and the North Carolina Department of Natural Resources and Environment (NCDENR) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. In 2000, EPA connected most residences overlying affected ground water to the public water system or installed filter systems. Site contamination does not currently threaten people living and working on or near the site. By monitoring ground water contamination and conducting required Five-Year Reviews, EPA and NCDENR continue to protect people and the environment from site contamination.
The 20-acre site is located along Davis Park Road, south of Hudson Boulevard and north of Blackwood Creek in Gastonia, North Carolina, a suburb of Charlotte. The site includes residential homes and an auto service shop. Residential areas, which include low-income residents, and commercial businesses surround the site.
The site includes an area of soil behind a building located at 2307 Davis Park Road and an area of contaminated ground water that spreads outward from this property and extends south along Davis Park Road to Blackwood Creek. After identifying contaminated soil during an initial assessment, investigators did not detect any contaminated soil during a more extensive follow-up investigation.
In 1999, EPA listed the site on the NPL.
Site investigations identified contamination in ground water that could potentially harm people in the area. Contaminants of concern include tetrachloroethylene (also known as PCE or PERC), trichloroethylene, 1,1-dichloroethene, chloroform and methyl-tert butyl ether.
The area of contaminated ground water has moved south, away from most of the residences previously affected, and toward Blackwood Creek. Investigators have not identified any contamination in the creek. Ground water treatment is underway through monitored natural attenuation. In 2000, EPA connected most residences overlying affected ground water to the public water system or installed filter systems. A few residents chose not to use these services. A well permitting program operated by the county health department prevents installation of new drinking water wells in areas impacted by the site.
NCDENR does not consider vapor intrusion to be a threat to people living or working on or near the site.
EPA considered children’s health issues as part of the site’s risk assessment.
Investigation and Cleanup Responsibility / Oversight
EPA leads site investigation and cleanup activities in cooperation with NCDENR. NCDENR will soon begin leading site cleanup activities.
Site Cleanup Plan
In 1998, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Connecting homes, churches and businesses in the site area to the Gastonia public water supply.
- Placing wellhead treatment systems on affected private wells, as an alternative to connecting them to the public water supply.
- Using natural attenuation to restore contaminated ground water.
- Monitoring ground water.
- Developing alternative plans to use a pump-and-treat system to address ground water contamination in case natural attenuation did not work as anticipated.
In 2000, EPA issued an Explanation of Significant Difference (ESD), which clarified that EPA would not need to use the alternative pump-and-treat cleanup approach to address ground water contamination. The ESD also extended the projected cleanup time needed for ground water to meet site cleanup goals.
In 2000, EPA began on-site cleanup activities, connecting 63 residences to the public water system. EPA also installed carbon filters at five residences where the homeowners chose not to connect to the public water system. Two residents with private wells in the affected area chose not to connect to the public water system or use a carbon filter.
EPA also physically abandoned 19 private wells, plugging the wells with a cement grout.
EPA conducts long-term ground water monitoring each spring.
In 2000, EPA issued a report confirming that natural attenuation is addressing ground water contamination and that ground water would meet site cleanup goals.
The site’s second Five-Year Review, completed in 2010, found there was a need for additional work before determining the protectiveness of the site’s cleanup approach. EPA is taking follow-up actions in response to the Five-Year Review recommendations.
EPA was unable to identify any viable potentially responsible parties for the site. EPA is using federal funds for site cleanup activities.
EPA worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA has conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices, letters to property owners, public meetings and community interviews as part of the site’s Five-Year Reviews.
EPA and NCDENR will continue to monitor the natural attenuation of ground water contaminants.
EPA completed the last Five-Year Review in 2010 and plans to complete the next Five-Year Review in 2015.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
