Site Background
The Davis Park Road TCE site includes approximately 20 acres of residential homes and private businesses in unincorporated Gaston County, southwest of the City of Gastonia. The site consists of a contaminated soil area that was reportedly behind an automobile transmission shop located at 2307 Davis Park Road and a plume of contaminated ground water that emanates from this property and extends south along Davis Park Road to Blackwood Creek. The plume of contaminated ground water underlies residences at the site along the plume's entire horizontal extent.
The approximate 20 acres that the site encompasses is mainly residential homes and private businesses. It is anticipated that the future land use will continue to be a mix of residential and commercial properties.
Threats and Contaminants
Tetrachloroethene, Trichloroethene, 1,1-Dichloroethene, Chloroform, and Methyl-ter-butyl ether are the ground water contaminants of concern identified for this site.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1998. Major cleanup elements for the site included:
- Connecting homes, churches, and businesses in the Davis Park Road Site area to the City of Gastonia public water supply.
- Optional wellhead treatment for affected private wells.
- Natural attenuation to restore the contaminated ground water.
- Continued analytical monitoring for contaminants in ground water.
- Develop contingency plans for ground water pump-and-treat if natural attenuation is not achieving expected levels.
An Explanation of Significant Difference (ESD) was signed in September 2000. Based on information gathered during cleanup design, EPA determined that the contingency pump-and-treat remedy was not needed. The ESD also extended the projected cleanup time for ground water to reach the remedial cleanup goals.
Cleanup Progress
On-site cleanup activities began in May 2000. A total of 63 residences were connected to the City of Gastonia water system and are now receiving water from that system.
EPA installed carbon filters at five residences where the homeowners did not agree to be connected to the public water supply system. Two residents with private wells in the impacted area elected not to receive either public water or a carbon filter.
EPA also physically abandoned 19 private wells by plugging the wells with a cement grout. Cleanup activities (construction) were determined to be complete in September 2000.
Long term monitoring of ground water is being conducted on a yearly basis each Spring, and an annual monitoring report is prepared. Ground water monitoring is expected to be ongoing for 30 years.
During the remedial design, a natural attenuation study was conducted to confirm that the contaminant plume is naturally attenuating. In a September 2000 memorandum report, EPA confirmed that natural attenuation was occurring at the site and would achieve remedial goals.
A Five-Year Review (FYR) was developed for the site in 2005. The FYR found that the remedy is protective of human health and the environment in the short-term but that ground water would need to be monitored to ensure long term protection.
Enforcement Activities
Community Involvement
EPA has conducted a range of community involvement activities at the Davis Park Road site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices, letters to property owners, and public meetings on cleanup activities and updates.
Future Work
EPA will continue to monitor the attenuation of the ground water contaminants.
The next FYR for the site is expected in 2010.
