Background

The 1-acre property where Geigy Chemical Corp. (Aberdeen Plant) and its predecessors operated is located in Aberdeen, North Carolina. It includes the area where pesticide blending, formulation and retail sale operations took place from 1947 to 1989. The U.S. Environmental Protection Agency placed the site on the Superfund program’s National Priorities List (NPL) in 1989 because of contaminated groundwater 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 groundwater and undertaking Five-Year Reviews, EPA, NCDENR and the site’s PRPs continue to protect people and the environment from site contamination.

The site is located in Aberdeen, Moore County, North Carolina. The one-acre property has a triangular shape. Highway 211 borders to the north and the Aberdeen and Rockfish rail line borders to the south. Commercial businesses, residential properties and undeveloped forested areas surround the property. The Aberdeen Contaminated Ground Water Superfund site is located next to this site. The Aberdeen Pesticide Dumps Superfund site is located approximately 2.5 miles northwest of this site. The Aberdeen and Rockfish Railroad owns the property. The site’s PRPs maintain the site. Grasses and trees cover the site, which is not currently in use.

What Has Been Done to Clean Up the Site?

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 completed the remedial investigation and feasibility study at the site.

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. The PRPs also completed construction of the groundwater treatment system in 1996 and began operating the system in 1997. EPA issued the Preliminary Close Out Report in July 1998 which documents the completion of all construction activities at the site.

EPA has conducted several Five-Year Reviews of the site’s remedy. These reviews ensure that the remedies, in place, protect public health and the environment, and function as intended by site decision documents. The most recent review completed in 2013 concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment in the short term. Continued protectiveness of the remedy requires the implementation of the appropriate institutional controls at the site. EPA plans to complete the fourth Five-Year Review in the fall of 2018.

What Is the Current Site Status?

The most recent Five Year Review was published by EPA HQs in 2018. Currently the Site is protective ofhuman 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 ofthe Site.

  • From 1947 to 1967, a pesticide blending and formulation facility operated on this property.
  • From 1968 until 1989, a retail distribution facility for agricultural chemicals operated at this property.
  • In 1989, the EPA listed the site on the NPL.
  • In 1992, EPA issued the site’s cleanup plan. It included extracting and treating groundwater on site and discharging the treated water to the local treatment facility or an infiltration gallery. In addition, the plan included demolishing the warehouse foundation and disposing of it off site; digging up the top foot of contaminated soil; and placing clean soil back in the dug-up areas. The plan also included monitoring groundwater and additional sampling and analyses of groundwater.
  • In 1998, EPA updated the cleanup plan to add monitored natural attenuation to address contaminated groundwater.
  • Ground water treatment and monitoring is ongoing. EPA is preparing an institutional control for the site and updating the ground water cleanup standard.
  • EPA completed the last Five-Year Review in 2013, which concluded the remedy is protective of human health and the environment.
