Current Site Status
The Aberdeen Pesticide Dumps site includes five separate areas impacted by industrial formulation and blending of pesticides and related waste disposal practices. EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated debris, ground water, soil, sediment and surface water resulting from facility operations. EPA, the North Carolina Department of Environment and Natural Resources (NCDENR), and the site’s potentially responsible parties (PRPs), 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. By treating and monitoring ground water, placing institutional controls on the site property and undertaking Five-Year Reviews, EPA, NCDENR and the site’s PRPs continue to protect people and the environment from site contamination.
The site, located near Aberdeen in Moore County, North Carolina, consists of five separate areas known as the Farm Chemicals Area, the Twin Sites Area, the Fairway Six Area, the McIver Dump Area and the Route 211 Area. The site includes an area where a pesticide formulation plant operated (the Farm Chemicals Area) and four areas where operations disposed of wastes from the formulation process. In 1989, EPA listed the site on the NPL. The Geigy Chemical Corporation (Aberdeen Plant) and the Aberdeen Contaminated Ground Water Superfund sites are located approximately 2.5 miles southeast of the site.
The 4-acre Farm Chemicals Area is located on the south side of N.C. State Highway 5 (Pinehurst Road), about 0.5 miles west of the road’s intersection with U.S. Highway 1. The Area borders the western edge of Aberdeen. Commercial and light industrial properties border the Area to the south and west. Residential land uses border the Area to the east; the nearest residence is approximately 200 feet away. Page's Lake is approximately 500 feet downhill from the Area. People use the lake for fishing and general recreation. From 1930 until 1987, a pesticide formulation plant operated at the Area. Parties demolished the facility in 1997. In 2004, part of the Area was redeveloped as a commercial mini-storage warehouse facility. An industrial and construction supply store and a coffee roaster also operate at the Area.
The four disposal areas include:
- The 22-acre Twin Sites Area is located north of N.C. State Highway 5, directly across from the Farm Chemicals Area. The area includes Disposal Areas A, B and C. Woods border the Area to the east; Page’s Lake borders the Area to the north; N.C. State Highway 5 and a Norfolk Southern rail line border the Area to the south; and Aberdeen and several residential properties border the Area to the east. From 1945 to 1971, operations at the Farm Chemicals Area disposed of pesticide-related waste at the Area. People currently use the Area for recreational purposes, including a public walking trail and fishing in Page’s Lake. View map.
- The 10-acre Fairway Six Area is located off N.C. State Highway 5 in a sparsely populated rural area, approximately 1.6 miles west-northwest of Aberdeen. From 1950 to 1971, operations at the Farm Chemicals Area disposed of dusts and granular pesticide waste as well as technical bags and containers at the Area. The Area is part of a golf Course. View map.
- The 80-foot Route 211 Area is located in a mostly rural and forested area approximately one mile east of Aberdeen. The Area was originally a sand borrow pit from a previous sand mining operation and later used for pesticide-manufacturing-related disposal. The owner currently uses the Area for storage of personal mechanical equipment and tools. Fencing and a locked gate control access to the Area. View map.
- The 1-acre McIver Area is located in a sparsely populated agricultural area west of Aberdeen. The Area consists of two sub-areas, Area B and Area C. A small stream, Patterson Branch, borders the Area to the north. A small community of single-family homes is located uphill from the Area. During the 1950s, operations at the Farm Chemicals Area disposed of materials containing pesticides and pesticide residues in Area B. Site investigations also discovered pesticide materials at Area C. Fencing and locked gates control access to the Area. The Area is not currently in use. View map.
Site investigations found contamination in debris, ground water, soil, sediment and surface water that could potentially harm people in the area. Contamination resulted from pesticide formulation and related waste disposal practices at the site. Contaminants of concern include benzene, hexachloride isomers, toxaphene, dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), dibromochloropropane, xylene, ethyl benzene and toluene.
Contamination affected ground water used for both the public water system and private water wells. EPA has contacted property owners with property overlying impacted ground water. A public water supply well is located downhill from the Route 211 Area; it is the only well known to be affected by site contamination. The site’s PRPs installed and maintain a ground water treatment system at the well used by the local water utility to provide water to area residents. At all other areas, ground water discharges to surface water. Sampling indicates there is no risk to people from coming into contact with contaminants in surface water.
EPA assessed whether residents or workers might be at risk from harmful ground water vapors in buildings. EPA found that vapor intrusion did not pose a threat to residents and workers. The use of fencing and warning signs addressed all other threats at the site.
Investigation and Cleanup Responsibility / Oversight
Bayer Corp., E.I. du Pont de Nemours and Co., Kaiser Aluminum & Chemical Corp., Syngenta (formerly known as Ciba Geigy Corp. and then Novartis Crop Protection Inc.), Olin Corp., Shell Oil Co., and Union Carbide Corp, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and NCDENR.
Site Cleanup Plan
The Agency has divided the site into four ongoing operable units (OUs):
OU1 & OU4 Soil at all 5 Areas
OU2 Renamed as OU4
OU3 Groundwater at Twin Site, Fairway Six and Farm Chemical Areas
OU5 Groundwater at Route 211 Area and groundwater, surface water, and sediment at McIver Dump Area.
In 1991, EPA issued a cleanup plan (a Records of Decision, or ROD) and ROD Amendment for the site. The plan included digging up contaminated soil and treating contaminated soil on site.
In 1992, EPA issued an Explanation of Significant Differences (ESD) to change the standards for the contamination levels in the dug-up soil.
In 1996, EPA issued a second ESD to change the depth for digging up contaminated soil and update the cleanup standard for arsenic in soils at the Farm Chemicals Area.
In 1993, EPA issued a cleanup plan (a ROD) to include the use of a pump-and-treat system for contaminated ground water at the Farm Chemicals, Twin Sites and Fairway Six Areas.
In 1994 and 1997, EPA issued ESDs to change the cleanup plan to include additional contaminants of concern and to use plants and their associated microorganisms to break down contamination as part of the cleanup plan.
In 2003, EPA issued a ROD Amendment that modified the cleanup plan to use monitored natural attenuation to address contaminated ground water.
In 1999, EPA issued a cleanup plan (a ROD) for contaminated ground water at the Route 211 Area and contaminated ground water, surface water and sediment at the McIver Area. The plan for the Route 211 Area included the following activities:
- Extracting and treating ground water in contaminant source areas.
- Using monitored natural attenuation to address ground water contamination.
The plan for the McIver Area included the following activities:
- Using monitored natural attenuation to address ground water, surface water and sediment contamination.
- Using plants and their associated microorganisms to break down contamination.
Between 1985 and 1989, EPA conducted cleanup activities at four of the site areas. EPA removed contaminated soil and either stockpiled it on site or took it off site for disposal.
In 1996, the site’s PRPs demolished 12 buildings at the Farm Chemicals Area. The PRPs used low-level heat to pull contamination from over 123,000 tons of contaminated soil from 1997 to 1998.
The PRPs completed cleanup construction at the Route 211 and McIver Areas in 1997 and 2000, respectively. EPA and the PRPs finalized the ground water cleanup plan design for the Farm Chemicals, Twin Sites and Fairway Six Areas in 1998.
Sampling of sediment, surface water and fish tissue from Page’s Lake in 2004 confirmed that site-related contaminant levels in the lake did not pose a threat to people.
In 2003, EPA issued the site’s Preliminary Close-Out Report, documenting the completion of all construction activities necessary to implement the site’s cleanup plan. EPA placed institutional controls on the Farm Chemicals Area to restrict land uses.
Prior to 2008, the PRPs conducted ground water sampling at the Farm Chemicals, Twin Sites and Fairway Six Areas on an annual basis. Since 2008, the PRPs have conducted sampling at the Fairway Six Area every five years as part of the Five-Year Review process. The PRPs sample and analyze ground water at the Farm Chemical and Twin Sites Areas every other year.
The site’s first Five-Year Review, completed in 2008, recommended development of a plan describing the approach for placing restrictive covenants, well drilling ordinances and institutional controls on properties affected by site contamination to prevent the installation of drinking water wells. The Agency with the assistance of NCDENR, is preparing the second Five-Year Review Report which should be completed by the end of September 2013.
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 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 fact sheets, public notices, interviews and information meetings.
The PRPs continue to conduct ground water cleanup activities. The PRPs continue to extract and treat contaminated ground water at the Route 211 Area and discharge the treated water back into the aquifer.
Ground water monitoring is ongoing.
EPA completed the last Five-Year Review in 2008 and completed the next Five-Year Review in 2013.
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.
