The Mallory Capacitor Company site is located on Belew Circle in the City of Waynesboro, Tennessee. The site is situated on the western bank of the Green River. The site comprises 8.6 acres and is located in a residential/commercial/industrial/business area in the eastern section of Waynesboro.
Originally developed in the late 1940s as a manufacturing facility for the footwear industry, in the late 1960s, P.R. Mallory acquired the site and began using it for electrical capacitor manufacturing. Facility operations ceased in 1984. Since cleanup actions in the late 1980s, all areas of the site became freely accessible to the public with the exception of the secured warehouse, which is currently unused.
Residential properties in the immediate vicinity of the site are serviced by municipally owned potable water and sanitary sewer services. Additionally, 54 private water sources have been identified within an approximate 1-mile radius of the site.
Polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs) have been detected in ground water. Off-site wells are contaminated with PCBs and VOCs such as trichloroethylene and dichloroethylene. Coming into contact with or accidentally ingesting contaminated ground water could pose a human health threat. The presence of PCBs and VOCs also poses a threat to the environment, as they are toxic to aquatic wildlife.
Site Cleanup Plan
Cleanup actions were first initiated in 1988. The Record of Decision (ROD), describing the cleanup approach for remaining site contamination, was issued in 1991. Major components of the cleanup approach included:
- Installation of approximately 14 ground water extraction wells in a phased approach.
- Pump and treatment of contaminated ground water on site.
- Investigations to better determine the northern extent of off-site ground water contamination.
- Investigations to determine possible impacts to Cold Water Creek.
- Institutional controls and monitoring.
- An effectiveness monitoring program.
From 1988 to 1989, a potentially responsible party (PRP) removed approximately 20,100 tons of PCB-contaminated soil and 3,400 cubic yards of plant debris. These materials were then sent to an EPA-approved disposal facility. Contaminated soils were excavated all the way to bedrock. In 1989, numerous monitoring wells were installed on and off site as part of the investigation to identify the nature and extent of PCB and VOC site contamination and cleanup alternatives.
Ground water extraction and treatment activities began in 1993 as specified in the 1991 ROD. Activities include ground water and sediment monitoring and periodic reporting to EPA.
In 2001, six additional monitoring wells were installed to better characterize and monitor the extent and cleanup of the ground water contamination. The 2003 Five-Year Review (FYR) concluded that the site cleanup approach was protective of human health and the environment.The 2008 FYR determined that the ground water extraction and treatment system continues to remain functional and effective. However, a protectiveness determination of the site cleanup approach could not be made until further information was obtained. Recommended follow-up actions included:
- Updating the 2002 private water well search to assure no potable water wells or drinking water sources exist within and immediately downgradient from the ground water plume emanating from the site.
- Determining whether a fish consumption exposure pathway from the Green River currently exists.
- Applying current statistical methods to confirm exposure point concentrations for PCBs in on site subsurface soils are protective of on site construction workers.
Follow-up research included as part of a FYR Addendum determined that:
- No potable water wells were identified downgradient from the site.
- The Green River adjacent to the site does not support a significant fish population for consumption since it is shallow, relatively fast-flowing, and the river bed consists of either exposed bedrock or bedrock covered by gravel/small stones, and there are no calm pools of deep water. The nearest location for edible fish habitat is thought to be approximately 5,000 feet downstream from the site.
- The potential risk and hazard to a construction worker from exposure to PCBs in site soil are within acceptable levels.
The FYR Addendum further noted that while the site cleanup approach currently protects human health and the environment in the short-term, additional actions are required to remain protective in the long-term. These include: implementing institutional controls and obtaining additional ground water samples to fully evaluate potential migration of the contaminant plume downgradient from the treatment area and towards the river.
Site cleanup activities are being led primarily by PRPs with oversight by EPA.
In 1988, a Consent Order was finalized allowing a PRP to conduct a Remedial Investigation/Feasibility Study of the site.
In 1992, EPA issued a Unilateral Administrative Order requiring a PRP to undertake the ground water cleanup effort at the site as presented in the 1991 ROD.
EPA has conducted a range of community involvement activities at the Mallory Capacitor Company 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 and information meetings on cleanup progress and activities.
Ground water treatment and related monitoring is ongoing.
The next FYR must be completed by 2013.
