| Abstract |
The 55-acre Golden Strip Septic Tank (GSST) site is an inactive waste hauling and disposal facility in Simpsonville, Greenville County, South Carolina. Land use in the area is predominantly residential. From 1960 to 1975, GSST used the site to dispose of industrial and septic wastes in five unlined lagoons. In 1975, GSST applied for an industrial solid waste permit to dispose of liquid wastes, but the State denied the permit because the proposed disposal method was unacceptable. The State continued its monitoring after the lagoons were filled and graded in 1978, and the results of the monitoring led to additional investigations by EPA in 1984 and 1986 and an RI and supplemental RI from 1989 to 1990 and 1990 to 1991, respectively. EPA identified metal contamination in lagoon soil and sludge, and limited contamination of ground water on the east side of the site. The Record of Decision (ROD) addresses remediation of contaminated soil, as well as sludge and surface water from the lagoons, as a final remedy. Ground water contamination is expected to naturally attenuate within 2 to 5 years after source remediation occurs. The primary contaminants of concern affecting the soil, sludge, and surface water are VOCs including benzene, PCE, toluene, and xylenes; other organics; and metals including arsenic, chromium, and lead. |
