Current Status

The Mathis Brothers Landfill (South Marble Top Road) site includes an area where a landfill operated from 1974 until 1980. EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated debris, ground water and soil resulting from landfill operations. EPA, the Georgia Environmental Protection Division (Georgia EPD) and Velsicol, the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. A water line connects nearby businesses and residents to the public water supply. By monitoring ground water, inspecting the site and undertaking Five-Year Reviews, EPA, Georgia EPD and the site’s PRP continue to protect people and the environment from site contamination.

Site Location and Background

The 10-acre site is 0.6 miles south of Highway 136 and 0.2 miles east of South Marble Top Road in Kensington, Walker County, Georgia. The site includes a 1.25-acre, grass-covered landfill area and forested land. A mobile home residence is located 400 feet southwest of the site. Undeveloped forested land surrounds the site. The site’s broader surroundings include agricultural and undeveloped land as well as low-density residential areas.

From 1974 until 1980, a landfill operated at the site. The landfill included three disposal areas: Areas A, B and C. In 1974, Georgia EPD identified a milky discoloration on the ground near the northeast portion of the landfill and required that the property owners stop accepting latex wastes and industrial solid wastes. In 1980, Georgia EPD determined the landfill did not meet the requirements of the Resource Conservation and Recovery Act (RCRA) and Georgia's Hazardous Waste Management Act and closed the landfill. In 1989, EPA listed the site on the NPL. Currently, the site is unused. The property owner has expressed interest in reusing the site for agricultural, industrial or commercial purposes.

Threats and Contaminants

Site investigations found contamination in debris, ground water and soil that could potentially harm people in the area. Contamination resulted from waste handling practices at the site.  Contaminants of concern include benzonitrile, dicamba, 1,4-dichlorobenzene and latex.

The site’s PRP has cleaned up debris and soil contamination. A soil cap and ground cover prevents people from coming into contact with remaining contamination. Fencing surrounds the site and limits access to the site.

Ground water contamination remains within the site’s boundary.

Site Cleanup Plan

In 1993, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. In 1996, EPA issued an amendment to the cleanup plan (a ROD amendment) to modify the cleanup plan. The modified plan included the following activities:

Summaries of site cleanup approaches are also available online in key site cleanup documents, including the ROD.

Cleanup Progress

The site’s PRPs conducted cleanup activities in 1997 and 1998, including digging up over 21,300 cubic yards of landfill material and contaminated soil, grading the site with berms around the dug-up area to prevent ground water from entering the area, regrading to divert surface water flow, and backfilling the dug-up area with 18,496 cubic yards of off-site soil. The PRPs also installed a liner and clean soil over the backfilled area, established a vegetative cover over the area, and transported 841,826 gallons of water off site for treatment and disposal.

The site’s second Five-Year Review, completed in 2007, found that the cleanup remains protective of human health and the environment. The Five-Year Review also recommended institutional controls to restrict use of ground water.

Summaries of cleanup activities are also available in Five-Year Reviews online.

Enforcement Activities

EPA negotiated legal agreements with the site’s PRP to investigate and clean up the site. The PRP continues to fund site cleanup, monitoring and oversight activities.

The ROD and Five-Year Reviews online provide additional information on specific legal agreements for the site.

Community Involvement

EPA has worked 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 has conducted 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 have included public notices, interviews and information meetings.

Future Work

The site’s PRP continues to monitor ground water, mow the vegetative cover, and inspect the cap and perimeter fencing semi-annually.

EPA is working to place institutional controls on the site property.

EPA completed the last Five-Year Review in 2007 and plans to complete the next Five-Year Review in 2012.
