The GMH Electronics site, formerly known as the Halifax Road site, is located in Roxboro, North Carolina. The sources of contamination associated with the site likely originated from at least three areas, including the former electronics operations area at the GMH property, a former gasoline station on the GMH property, and a former gasoline station across the intersection. The site includes a contaminated groundwater plume that extends beyond these two properties. Residential properties are located on the northeast and southwest corners of the intersection, as well as on all sides of the site. The U.S. Environmental Protection Agency placed the site on the Superfund program’s National Priorities List (NPL) in 2009 because of contaminated groundwater resulting from facility operations. EPA, the North Carolina Department of Environment and Natural Resources (NCDENR), and the U.S. Geological Survey (the USGS) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. By conducting groundwater studies and preparing a cleanup plan for the site, EPA, NCDENR and the USGS continue to protect people and the environment from site contamination.
What Has Been Done to Clean Up the Site?
The site is located at 1800 Virgilina Road, three-quarters of a mile northeast of Roxboro in Person County, North Carolina. The site includes the GMH Electronics building, which is located on the southeast corner of the Halifax Road and Virgilina Road intersection, and a former gas station, which is located on the northwest corner of the intersection. EPA believes these two buildings are the source areas of contamination found in residential drinking water wells. Site surroundings include residential properties, forested areas and commercial businesses. GMH Electronics operated an electronics facility at the site. In 2009, EPA listed the site on the NPL.
- EPA leads site investigation and cleanup activities in cooperation with NCDENR. The USGS has assisted EPA with site groundwater investigations.
- In 2007, EPA began immediate distribution of bottled water to 17 residences. EPA also installed filter systems at five homes with high levels of contamination in drinking water. NCDENR installed filter systems at two additional homes.
- In 2008, EPA sampled 89 private drinking water wells near the site and found contamination in 45 of the wells. In response, EPA provided bottled water to 13 additional homes.
- In 2009, EPA evaluated three cleanup alternatives to prevent people’s exposure to contaminated drinking water. EPA also published a Proposed Plan, which outlined connecting all residents with contaminated drinking water wells and residents in a 500-foot buffer zone around the last contaminated well to the public water supply. EPA then issued an interim cleanup plan to carry out these activities.
- In 2010, EPA and Person County completed construction of the water line, connecting 42 homes to the public water supply. Upon completion, EPA removed the site’s water filtration systems and terminated bottled water service to local homes and businesses. Person County has overseen the abandonment of private wells and several contaminated wells near the site area.
- In 2011, EPA and the USGS began an on-site groundwater study using existing wells.
- EPA is currently designing a remedial systems to treat the most contaminated portions of the site as outlined in the 2014 Record of Decision for the site.
- The week of April 2018, a monitoring sampling event was conducted at the site. Approximately 30 groundwater samples was collected. The data collected will help determine if the previously completed Remedial Design for the site requires any updates.
What Is the Current Site Status?
In April 2009, EPA issued an interim plan to mitigate risks at the site. The plan included connecting affected or potentially affected residents and businesses as well as residents living in a 500-foot buffer zone around the last contaminated well to the public water supply. If citizens elected to connect to the public water supply, then site contamination does not currently threaten them.
In September 2014, EPA issued a second interim site plan to mitigate risks at the site and clean up site areas called a Record of Decision. EPA is currently designing the site remediation and/or construction and operation of the remedy, performance monitoring, institutional controls, and any special requirements necessary to implement the September 2014 Record of Decision.
