South Cavalcade Street Superfund site
EPA Extends Public Comment Period for Houston Superfund Site Proposal
The U.S. Environmental Protection Agency Region 6 (EPA) has issued the second Record of Decision (ROD) Amendment for the South Cavalcade Street Superfund Site, Houston, Texas. The ROD Amendment was signed by EPA on September 24, 2014. EPA's selected remedy stems from field investigations and evaluation of the data. The remedy selected for contaminated groundwater at the site is a Technical Impracticability Waiver with short-term and long-term monitoring and institutional controls.
The South Cavalcade Street Superfund Site occupies approximately 66 acres of land located approximately three miles north of downtown Houston, Texas, and about one mile southwest of the intersection of Interstate Loop 610 and U.S. Highway 59. Wood treating and coal tar distillation operations at the site from 1910 to 1962 contaminated both soil and groundwater. The site was added to EPA's national priorities list of contaminated sites in 1984. Since then, contaminated soils have been contained and capped onsite, protecting human health and the environment from exposure. There is no known exposure to groundwater in the area, as drinking water is provided from other sources by the City of Houston.
