The 66-acre South Cavalcade site is located in Houston, Texas. A former wood-treating plant operated on site from 1910 to 1962. A coal tar distillation plant also operated on site from 1944 to 1962. These activities contaminated soil and groundwater with volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and metal salts such as arsenic, chromium, copper, lead, and zinc. Following cleanup, operation and maintenance activities and groundwater monitoring are ongoing.
