Information about the Columbia Nitrogen Superfund Site

The Columbia Nitrogen Site is a 43-acre site located on the Ashley River in Charleston, S.C., surrounded by two other sites and industrial and commercial businesses. A phosphate fertilizer facility operated on the site from 1905 until 1972. In 1980, Columbia Nitrogen Corporation demolished all on-site structures. In 1985, Columbia Nitrogen Corporation sold the site to a company that leased it to container-storage companies. In 2003, Ashley II of Charleston purchased the site.

Site investigations found lead and arsenic contamination in ground water, surface water, sediment and soil that resulted from the former phosphate fertilizer manufacturing operations at the site. Contamination does not extend beyond the site boundary, and a water line connects residents and businesses near the site to the public water supply. More information on the Columbia Nitrogen Superfund Site.
