Conditions at proposal (October 15, l984): The South Cavalcade Street Site covers approximately 69 acres in Houston, Harris County, Texas. The site, located in an industrial area on the south side of Cavalcade Street, has a history of wood-treating operations dating to 1911. Contaminants at the site consist of polynuclear aromatic compounds associated with CREOSOTE, in addition to other similar contaminants. EPA's analysis of historical aerial photographs indicates there are at least three waste pits on the site that have been filled or paved over. Analyses conducted by EPA indicate widespread on-site contamination of soil (both on and below the surface) and shallow ground water with BENZOPYRENE, CHRYSENE, FLUORANTHENE, and ANTHRACENE. About l0,000 people use wells within 3 miles of the site as a source of drinking water. Status (June 10, l986): In March 1985, Koppers Co., Inc., which has been identified as potentially responsible for wastes associated with the site, signed an Administrative Order on Consent with EPA.  More...
