Site Background
The Geigy Chemical Corporation site is an approximately 1-acre parcel of land located in Aberdeen, Moore County, North Carolina. From 1947 to 1967, the site operated as a pesticide blending and formulation facility. In 1968, the site began to operate as a retail distribution facility for agricultural chemicals, and continued operations until 1989. Sampling investigations revealed the presence of site-related pesticides in the soil and ground water.
Threats and Contaminants
Soils and ground water have been contaminated with pesticides and volatile organic compounds (VOCs). Soil contamination is restricted to the facility while the ground water plume is over one mile long. The city of Aberdeen obtains its water from municipal ground water wells; residents in the area also have private drinking water wells.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1992. Major cleanup elements for the site included:
- Extraction of ground water across the site in the upper aquifer and the second uppermost aquifer that is contaminated above maximum contaminant levels or the North Carolina Ground Water Standards, whichever are more protective.
- On-site treatment of extracted ground water with carbon adsorption to remove contaminants.
- Discharge of treated ground water to the local publicly owned treatment works or an infiltration gallery.
- Continued analytical monitoring for contaminants in ground water.
- Demolition of the former warehouse’s foundation with off-site disposal at a municipal or secure landfill.
- Excavation of the top foot of on-site soils that are contaminated above the performance standards.
- Testing of excavated contaminated soil with off-site incineration of soils that fail the toxicity characteristic leaching procedure (TCLP) test and off-site disposal in an approved hazardous waste landfill of soils that pass the TCLP test.
- Backfilling, grading and revegetation of excavated area.
- Additional sampling and analyses of the second uppermost aquifer to determine the extent of pesticide contamination, and to determine if the trichloroethylene found in two wells is site-related.
Cleanup Progress
The potentially responsible parties (PRPs) conducted three removal actions in 1989, 1991, and 1996 to remove all the contaminated soil from the site. The property was then landscaped to the specifications of the area's beautification committee. The soil remediation at the site has been completed.
The ground water treatment system was completed in 1996 and became fully operational in January 1997. An explanation of significant differences was signed in January 1998 which added additional downgradient monitoring to the remedy. Ground water treatment and monitoring is ongoing.
Enforcement Activities
EPA entered into a Consent Decree with three PRPs in March 1993 to conduct the design and construction of the remedy.
Community Involvement
EPA has conducted a range of community involvement activities at the Geigy Chemical Corporation 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
This site is subject to Five-Year Reviews (FYRs). The second FYR for this site was completed in September 2008. Efforts to address the recommendations of the FYR, including preparation of an Institutional Control implementation plan and updating ground water performance standard models, are currently underway. The third FYR is to be completed by the end of September 2013.
