Current Site Status
The JFD Electronics/Channel Master site includes an area where an antenna, amplifier and booster manufacturing facility operated from 1961 to 1984 and a packaging and distribution facility for electronic parts operated from 1984 to 2003. EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated ground water, sludge and soil resulting from operations and waste handling practices at the site. EPA, the North Carolina Department of Environment and Natural Resources (NCDENR), and the site’s Potentially Responsible Party (PRPs), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. By treating and monitoring ground water, performing additional studies, preventing exposure and undertaking Five-Year Review, EPA, NCDENR and the site’s PRPs continue to protect people and the environment from site contamination.
The 13-acre site is located at 620 West Industry Drive, two miles southwest of downtown Oxford in Granville County, North Carolina. The site includes the concrete slabs and foundations of two industrial buildings, the former Channel Master main building and the former Bandag Warehouse building. Pine Tree Road borders the site to the north. West Industry Drive borders the site to the west. A Norfolk Southern rail line borders the site to the south. A residential area borders the site to the east. The residential area includes homes and an apartment complex, which includes low-income and minority residents.
From 1961 to 1984, an antenna, amplifier and booster manufacturing facility operated at the site. Beginning in 1964, operations disposed of sludge generated by treating wastewater from conversion and electroplating processes, primarily rinse water from a chromate conversion process and copper/nickel electroplating into an on-site lagoon covering approximately 23,400 square feet. In 1989, EPA listed the site on the NPL.
From 1984 to 2003, a packaging and distribution facility for electronic parts operated at the site. In 2008, buildings on site were demolished. The site is not in use, except for ongoing ground water treatment activities. The concrete slabs and foundations from the former facilities remain on site. Zoning limits the site to industrial land use. The North Carolina well permitting statute prohibits access to ground water within the plume of contamination.
Site investigations found contamination in ground water, sludge and soil that could potentially harm people in the area. Contamination resulted from waste handling practices at the site. Contaminants of concern include metals, hexavalent chromium, cyanide and volatile organic compounds.
The site’s PRPs have cleaned up contaminated soil and sludge.
Ground water contamination remains on site and has migrated off site.
In 2006, EPA assessed whether residents or workers might be at risk from harmful ground water vapors in buildings. EPA found vapor intrusion at low levels. Vapor intrusion no longer poses a threat because parties demolished on-site buildings in 2008. Based upon the results of a December 2012 investigation, contaminated ground water hasa migrated off site and extends under the western portion of the Oak Ridge Apartments. A vapor intrusion study was conducted in 2012 and 2013 for the apartment units in closest proximity to the ground water plume. The results indicated that the apartment residents were not impacted by site-related contaminants present in the ground water.
Investigation and Cleanup Responsibility / Oversight
JFD Electronics Corporation and Channel Master Satellite Systems, Inc., the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by the EPA and NCDENR.
Site Cleanup Plan
In 1992, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Using a pump and treat system to address contaminated ground water.
- Treating ground water on site usin alkaline-chlorination, precipitation/filtration, air stripping and carbon adsorption to remove organic contaminants.
- Discharging treated ground water to the local water treatment plant or a nearby surface water pathway.
- Monitoring ground water.
- Digging up contaminated sludge and soil.
- Treating contaminated sludge and soil on-site using reduction, oxidation and stabilization.
- Backfilling treated sludge and soil in dug-up areas on site.
- Capping the backfilled areas to minimize people coming in contact with any residual contamination, to impede the infiltration of any residual contamination into the ground water aquifer, and to minimize the possibility for surface water runoff from the area of contamination.
- Installing additional monitoring wells.
In 1996, EPA issued an Explanation of Significant Difference (ESD) that updated the ground water treatment approach approved in the 1992 cleanup plan (ROD).
In 1999, EPA issued an amendment to the cleanup plan (a ROD amendment). The plan included the following activities:
- Digging up 1,750 cubic yards of contaminated sludge.
- Disposing of contaminated sludge off site at a treatment and disposal facility.
- Reducing any hexavalent chromium present in contaminated sludge to trivalent chromium.
- Stabilizing contaminated sludge to meet disposal requirements for the off-site disposal facility.
- Disposing of treated and stabilized sludge at an off-site facility.
In 1996, EPA issued a second ESD to update cleanup activities for addressing contaminated soil and sludge. The ESD included digging up and disposing of contaminated soil at an off-site landfill, backfilling the dug-up areas with clean soil, and grading and seeding the backfilled areas.
The site’s PRPs began operating the ground water pump-and-treat system in 1998. The PRPs temporarily suspended the system due to cyanide concentrations above surface water discharge criteria. The PRPs modified the system and restarted it in 2000. The system treats and discharges 22,000 gallons per day.
In 2000, the PRPs dug up and transported contaminated soil and sludge off site for treatment and disposal. The PRPs filled the dug-up areas with clean soil, compacted and sloped the area for proper drainage, and planted grass.
The site’s second Five-Year Review, completed in 2010, found there was a need for additional work before EPA could make a statement about the protectiveness of the cleanup approach. Recommendations included determining how far contaminated ground water had spread, evaluating the need for additional ground water pumping wells, and completing a ground water well survey to confirm that people are not drinking water from a well located within the area of contaminated ground water. EPA and the PRPs began these activities in 2011. A significant finding was that the pump-and-treat system was not functioning as intended. The extent of the ground water plume is not captured with the current system and off-site contaminant migration is ongoing. The PRPs are currently preparing a work plan to conduct additional investigative activities to address items noted in the 2010 Five-Year-Review and in the December 2012 investigation.
EPA negotiated legal agreements with the site’s PRPs to investigate and clean up the site. The PRPs continue to fund site cleanup, monitoring and oversight activities.
EPA is working 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 is conducting 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 included public notices, interviews, and public meetings.
EPA and the site’s PRPs are working to address the issues identified in the second Five-Year Review.
Ground water treatment and monitoring are ongoing. EPA and the PRPs plan additional investigations to further characterize the contamination in the ground water treatment system in place. The PRPs are preparing a work plan to address these items. Additional remedial actions are anticipated.
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.
