Site Background
The JFD Electronics/Channel Master site is a 13- acre property in Oxford, Granville County, North Carolina, that was the site of an antenna, amplifier, and booster manufacturing facility from 1961 to 1984. A lagoon covering approximately 23,400 square feet was built in 1964-65 to dispose of sludge generated by treating wastewater, primarily rinse water from a chromate conversion process and copper/nickel electroplating. In 1983, half of the lagoon was filled and used as a truck parking lot. The property is currently used as a warehouse and distribution center.
Threats and Contaminants
Site investigations confirmed the presence of soil and sludge contaminated with metals and cyanide, as well as ground water contaminated with volatile organic compounds (VOCs) and cyanide. This contamination appears to be associated with leaking underground tanks of waste oil used in former facility operations and with an area where trucks with waste oil had been rinsed.
An estimated 2,500 people obtain drinking water from private wells within three miles of the site, the closest approximately 2,000 feet to the southeast. The site drains to an unnamed tributary of Fishing Creek, which is used for recreational fishing within three miles downstream of the site.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1992. Major cleanup elements for the site included:
- Extraction of site ground water from the overburden/fractured bedrock aquifer that is contaminated above maximum contaminant levels (MCLs) or the North Carolina Ground Water Standards.
- On-site treatment of extracted ground water via alkaline-chlorination, precipitation/filtration, air stripping, and carbon adsorption to reduce contaminants to either MCLs or State Standards, whichever are most protective.
- Discharge of treated ground water to the local publicly owned treatment works or a nearby surface water pathway.
- Continued monitoring for contaminants in ground water.
- Excavation of contaminated sludge and soil and on-site treatment using reduction, oxidation and stabilization until the land disposal restrictions or treatability variance treatment levels established for the metals of concern have been met.
- On-site disposal, or backfilling, of the treated sludge and soil into the excavated area.
- Placement of a cap over the treated sludge and soil to: 1) minimize the potential for adverse health risks due to direct contact with residual contamination; 2) impede the infiltration of any residual contamination into the ground water aquifer; and 3) minimize the possibility for surface water runoff from the area of contamination.
- Installation of additional monitoring wells during the remedial design to further characterize the nature and extent of ground water contamination.
Cleanup Progress
The ground water pump-and-treat system was initiated in July 1998, but had to be suspended due to cyanide concentrations above surface water discharge criteria. Modifications were made so that the system would discharge to the City of Oxford wastewater treatment system, and the system was restarted in April 2000. Ground water treatment is ongoing and currently operates at the average rate of 22,000 gallons of water treated and discharged per day.
Contaminated soil and sludge were excavated and transported off site for treatment and disposal during the summer of 2000. The excavated areas were filled with clean soil, compacted, sloped for proper drainage and grass was planted.
Site cleanup activities are being led primarily by potentially responsible parties (PRPs) with oversight by EPA.
Enforcement Activities
The PRPs agreed to clean up the site under a consent decree signed in August 1993.
Community Involvement
EPA has conducted a range of community involvement activities at the JFD Electronics/Channel Master 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, interviews, and public meetings on cleanup activities and updates.
Future Work
The second Five Year Review was completed in September 2010. The issues raised in the review are currently being addressed by the PRP.
