Current Site Status

The Geigy Chemical Corp. - Aberdeen Plant site includes the area where pesticide blending, formuation and retail sale operations took place from 1947 to 1989. EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated ground water and soil 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. A water line connects residences and businesses to the public water supply. By treating ground water and undertaking Five-Year Reviews, EPA, NCDENR and the site’s PRPs continue to protect people and the environment from site contamination.

Site Location and Background

The 1-acre site is located in Aberdeen, Moore County, North Carolina. The site has a triangular shape. Highway 211 borders the site to the north and the Aberdeen and Rockfish rail line borders the site to the south. Commercial businesses, residential properties and undeveloped forested areas surround the site. The Aberdeen Contaminated Ground Water Superfund site is located next to the site. The Aberdeen Pesticide Dumps Superfund site is located approximately 2.5 miles northwest of the site.

From 1947 to 1967, a pesticide blending and formulation facility operated on the site. From 1968 to 1989, a retail distribution facility for agricultural chemicals operated at the site. In 1989, EPA listed the site on the NPL.

The Aberdeen and Rockfish Railroad owns the site property. The site’s PRPs maintain the site. Grasses and trees cover the site, which is not in use.

Threats and Contaminants

Site investigations found contamination in ground water and soil that could potentially harm people in the area. Contamination resulted from pesticide blending and formulation operations at the site. Contaminant of concern include pesticides and volatile organic compounds (VOCs).

Contamination affected soil within the site boundary. Contamination also affected ground water, which extends southwest of the site and discharges into Aberdeen Creek. Ground water contamination associated with the site mixed with ground water contamination associated with the Aberdeen Contaminated Ground Water site.

The City of Aberdeen shut down one of the contaminated public water supply wells. A treatment system, installed immediately downhill from the site, removes contamination from the ground water. Contamination affected some private wells; however, a water line connects residences and businesses to the public water supply.

Investigation and Cleanup Responsibility / Oversight

Syngenta Crop Protection (successor to Novartis Crop Protection and Ciba-Geigy Corporation), Olin Corp, Kaiser Aluminum & Chemical Corp, Lebanon Chemical Corp, Aberdeen and Rockfish Railroad, and Columbia Nitrogen Corporation, the site’s PRPs, lead site investigation and cleanup activities, with oversight provided by EPA and NCDENR. Between 1988 and 1992, the PRPs conducted the Remedial Investigation and Feasibility Study at the site.

Site Cleanup Plan

In 1992, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:

In 1998, EPA signed an Explanation of Significant Differences to add monitored natural attenuation to the cleanup plan.

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 1989, 1991 and 1996 to remove all contaminated soil, debris and structures from the site. The PRPs completed soil cleanup activities in 1998 and EPA prepared a close-out report.
The PRPs completed construction of the ground water treatment system in 1996 and began operating the system in 1997.

The site’s first and second Five-Year Reviews were completed in 2003 and 2008, respectively. The third Five-Year Review was completed in September 2013 and found that the cleanup remains protective of human health and the environment in the short-term because soil contamination was remediated through source removal and groundwater contamination is being remediated by an active pump and treat system at the Site and MNA downgradient of the Site. The remedy currently protects human health and the environment because no human or ecological exposure pathways exist to contaminated groundwater. However, in order for the remedy to be protective in the long-term and for the completion of the requirements necessary to close out the remedy, the following action needs to be taken: issue an ESD that requires the implementation of the appropriate institutional controls at the Site.

The fourth Five-Year Review is planned to be completed in September 2018.

These Five-Year Review Reports can be viewed online at:  http://cumulis.epa.gov/fiveyear/?fuseaction=home.showSearchForm

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

Enforcement Activities

EPA negotiated legal agreements with the site’s PRPs to investigate and clean up the site. The PRPs continue to fund previous EPA and NCDENR response costs as well as 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 public meetings.

Future Work

Ground water treatment and monitoring is ongoing.

EPA completed the last Five-Year Review in 2013 and plans to complete next Five-Year Review in 2018.
