Superfund Record of Decision (EPA Region 6): South Cavalcade Street Site, Houston, Texas (First Remedial Action) September 1988

摘要

The 66-acre South Cavalcade site is located in northeast Houston, Texas. The surrounding areas are a mixture of residential, commercial, and industrial properties. Stormwater runoff flows to two stormwater drainage ditches, which flow into Hunting Bayou, a limited aquatic habitat as classified by Texas Water Quality Standards. The site was used as a wood preserving and coal tar distillation facility from 1910 to 1962. The wood preserving facility consisted of an operations area, a drip track, and treated and untreated wood storage areas. The operations area included wood-treating cylinders, chemical storage tanks, and a waste water lagoon. Creosote and metallic salts were used in the operation. PAHs, VOCs, metals and components of creosote were detected in the soil, sediments, and ground water. The primary contaminants of concern affecting the ground water, soils, and sediments are VOCs including benzene, toluene, and xylenes, other organics including PAHs, and metal including arsenic, chromium, and lead. The selected remedial action for the site is outlined.
