• NORTH CAVALCADE STREET, HARRIS County, TX

Stage of Clean-up: Construction Underway

Conditions at proposal (October 15, l984): The North Cavalcade Street Site covers approximately 23 acres in Houston, Harris County, Texas. The site is in an industrial area on the north side of Cavalcade Street. Houston CREOSOTE occupied the site from 1946 until the early 1960s, when the company ceased operations. Based on a review of aerial photographs and a contamination survey, EPA concluded that a filled-in CREOSOTE pit is located within the site. Contaminants at the site consist of polynuclear aromatic compounds associated with CREOSOTE and PENTACHLOROPHENOL, in addition to contaminants from metal wood-treating (wolmanizing) processes. Analyses conducted by a consultant to the City of Houston indicate that soils (both on and below the surface) and shallow ground water on the site are contaminated with CHRYSENE, FLUORANTHENE, ANTHRACENE, and wood-treating metals. About l0,000 people use wells within 3 miles of the site as a source of drinking water.  More...
