Site Description

BASF, formerly American Cyanamid Corporation (ACC) Agricultural Division, is a 683 acre site, located at the intersection of Quakerbridge Rd and US Route 1 in West Windsor, NJ. BASF bought the operations of ACC Agricultural Division from American Home Products (who purchased American Cyanamid in 1994) in 2000.  However, American Home Products retained ownership of the 683 acre property less the liability for the cleanup of the contaminated SWMUs on site.  American Home Products changed its name to Wyeth Corp in March 2002.  Real estate development company, Rouse Corp, purchased the property from Wyeth Corp for $35 million in 2006.

No manufacturing or production was conducted at the site, which is now shutdown.  The activities included research and development of agricultural chemicals and animal health and nutrition products. There are woodlands and farmland near the site. BASF is cleaning up the site under a New Jersey Department of Environmental Protection (NJDEP) order.

Potential Threats and Contaminants

The groundwater and soil at the site have been contaminated with pesticides, (4,4-DDT and 4,4-DDE, No.2. Delta-BHC), chloroform and carbon tetrachloride. The main source of contamination of the groundwater is a landfill (Landfill No. 2), which is located in a wooded area in the southern section of the site. It was used to dispose of laboratory glassware and small containers of laboratory wastes.

Cleanup Approach and Progress

The contents of Landfill No. 2 were completely excavated in 1995 and taken off-site for proper disposal. Because the source was removed, the contamination of the groundwater is expected to naturally degrade and dilute. BASF has been monitoring the groundwater near the landfill. It has found that pesticides and organic compounds have generally been decreasing since 1995, except that chloroform and carbon tetrachloride concentrations have fluctuated. There is some remaining soil contamination and therefore, the future use of part of the property is restricted to industrial use so that human exposure is limited.

BASF will continue to monitor the groundwater. If concentrations of chemicals begin to increase, BASF will be required to take additional measures to clean up the groundwater.
