Current Status

The Hercules 009 Landfill site includes the area where Hercules, Inc. operated a pesticide manufacturing facility and landfill from 1948 until 1980. EPA placed the site on the National Priorities List (NPL) in 1984 because of contaminated ground water, sludge and soil resulting from facility operations. EPA, the Georgia Environmental Protection Division (Georgia EPD) and Hercules Inc., 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 residences and businesses to the public water supply. By monitoring ground water, maintaining the landfill cover 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 16.5-acre site is located in Brunswick, Glynn County, Georgia, approximately two miles south of Interstate 95. The site includes a 7-acre inactive landfill. Site surroundings include commercial and residential land uses. An automobile dealership borders the site to the north; a forested area, several residences, a church, a school and a shopping center border the site to the south and east; and a road borders the site to the west. Altama Elementary School is located northeast of the site. EPA sampled soil from school grounds and determined that site contamination did not affect the school. In addition, three other Superfund sites are located in Brunswick. These include the Brunswick Wood Preserving site, the LCP Chemicals Georgia site and the Terry Creek Dredge Spoil Area / Hercules Outfall site.

From 1948 to 1980, a pesticide manufacturing facility and a landfill operated at the site. Operations disposed of wastewater from manufacturing processes at the 7-acre landfill on site. The landfill also received drums, glassware and other waste. Operations at the site ended in 1982.

In 1984, EPA listed the site on the NPL. Currently, the automobile dealership located next to the site uses a large portion of the site as a paved parking lot.

Threats and Contaminants

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 identified included volatile organic compounds (VOCs), toluenexylene, arsenicchromium benzenetrichloroethylene (TCE) and lead.

Investigation and Cleanup Responsibility / Oversight

Hercules, Inc., the site’s PRP, led site investigation and cleanup activities, with oversight provided by EPA and Georgia EPD.

Site Cleanup Plan

In 1991, EPA issued an interim cleanup plan (an interim Record of Decision, or ROD) to address potential ground water contamination around local private wells.

In 1993, EPA issued a second cleanup plan (ROD) for the site. The plan included the following activities:

In 1998, EPA issued an Explanation of Significant Differences (ESD) to address the construction of the landfill cap and the treatment depth of contaminated subsurface soil and sludge.

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

Cleanup Progress

In 1992, parties installed a water line to connect residential properties and a church near the site to the public water supply. Additionally, parties discovered contamination in the yards of residences next to the site. Parties temporarily relocated residents while the PRP dug up contaminated soil and replaced it with clean soil. From 1994 until 1995, the PRP dug up approximately 8,000 cubic yards of contaminated soil on site and stockpiled it on site for treatment. Between 1998 and 1999, the PRP stabilized contaminated sludge and soil from the landfill and constructed a cap over the stabilized sludge and soil. The PRP placed fencing around the site property and additional fencing around the landfill cap area.

In the mid-2000s, a local community group, the Glynn Environmental CoalitionExit Disclaimer, shared

concerns with EPA’s Inspector General that EPA’s approved test method was insufficient. Based on these concerns, EPA developed a new analytical test method. EPA developed this approach in collaboration with the site’s PRP as well as with input from other scientific groups. EPA then applied this new analytical approach to ground water samples collected at the site in 2006. EPA’s analysis determined that substances identified in the ground water samples did not pose a threat to people or the environment. For its work, EPA Region 4 received an EPA Scientific Achievement Award.

The site’s third Five-Year Review, completed in 2011, found that the cleanup remains protective of human health and the environment; however, institutional controls need to be put in place on the site property.

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.

RODs 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. EPA also issues a biannual environmental cleanup newsletter that addresses all Superfund sites in Brunswick.

EPA awarded the Glynn Environmental Coalition Exit Disclaimer multiple Technical Assistance Grants to support community outreach and engagement at the Superfund sites located in Brunswick, including the Hercules 009 Landfill site.

Future Work

EPA is currently working with the PRP and Georgia EPD to place institutional controls on the site property to restrict activities that could damage the landfill cap area as well as limit land and ground water use at the site.  

Monitoring of ground water and operation and maintenance of the landfill cap are ongoing.

EPA completed the last Five-Year Review in 2011 and plans to complete the next Five-Year Review in 2016.
