In 1977, the Department relocated all laboratory operations and personnel to Illinois, and declared the New Jersey facility surplus. Partial remediation of the site was performed in 1978 and from 1981 through 1983. The site poses no health risks. The only remaining areas of contamination are the area where the old rail siding was filled in and two small subsurface areas. A fence with locked gates restricts public access.
Vegetation covers the surface to prevent contaminant migration via runoff from contaminated soils.
Gamma activity from the contaminated areas is low, and site contaminants do not affect local ground water. Because the Department of Energy owns the site, future use of the site after remediation depends on disposition of the property by the General Services Administration. If the property is released for private ownership, it is likely to be developed for industrial uses because of zoning restrictions and prevalent use of surrounding property. The New Brunswick Site is being cleaned up under the Comprehensive Environmental Response, Compensation, and Liability Act. Key regulators include the New Jersey Department of Environmental Protection, Environmental Protection Agency Region II, and the local health department.
