Site Background:
At one time, the 2-acre South Carolina Recycling and Disposal, Inc. (SCRDI) Dixiana site contained over 1,100 drums of materials such as paints, solvents, acids, waste oils, phenols, and dyes. In 1978, SCRDI leased the site for drum storage of industrial wastes. Instances of poor handling practices, leaky drums, and exposure to the weather created a number of discharges to the environment prior to drum removal. As a result of several investigations conducted by SCDHEC, volatile organic compounds were found in the groundwater and visibly contaminated soil containing high levels of metals and volatile organic compounds located throughout the site. Approximately 1,200 people use water supply wells within 3 miles of the site. And results from to residences adjacent to the site had detectable concentration of volatile organic compounds.

Cleanup Progress: Construction Completed
A 1978 SCDHEC suit against SCRDI resulted in a Court Order which banned further shipments of waste to the site. Thereafter, SCRDI removed all drummed wastes from the site. In addition to moving drummed wastes, visibly contaminated surface soil was stockpiled and later removed from the site. SCDHEC also informed the owners of the residential wells located adjacent to the site of the contamination and advised them to seek an alternative drinking water supply. These residences now utilize municipal water from the City of Cayce. During 1984 and 1985, EPA conducted a Remedial Investigation/Feasibility Study for the site. The remedial investigation results confirmed that the site did not contain buried wastes or significant contamination in the surface water, sediments, or soils and air-borne contaminants were not a problem at the site. The remedial investigation did however further confirm volatile organic compound contamination in the groundwater underlying the site. Some semi-volatile organic compounds and metals were also detected at low concentrations in the groundwater. EPA issued a Record of Decision (ROD) on September 26, 1986, which selected a groundwater interception and extraction system as the remedy for groundwater contamination at the site. Construction of the remedy for the site commenced on October 15, 1990 and completed September 23, 1992. In addition, a five-year review for the site was completed on September 29, 1995 which determined that the selected remedy for the site was protective of human health and the environment. While the system was performing as designed, additional modifications were made to improve the overall effectiveness of the treatment system and control off-site migration of the groundwater plume. All work conducted to enhance the system was performed by the potentially responsible parties. The potentially responsible parties under EPA oversight, are also performing operation and maintenance of the system. Over 100,000,000 gallons of groundwater have been extracted, treated, and discharged to the local publicly owned treatment works. A second five-year review was completed September 28, 2000. Based on the results of the second five-year review, the treatment system is operating and functioning as designed. Levels of contaminants are decreasing and the migration of the groundwater plume is under control. The third five-year review was completed in September 2005. Based on the results of the third five-year review, the treatment system is operating and functioning as designed. Levels of contaminants are decreasing and the migration of the groundwater plume is under control. The fourth Five-Year Review will be completed by September 2010.
