Current Site Status
The Palmetto Wood Preserving site includes the area where the Palmetto Wood Preserving Company operated a wood preserving facility from 1963 until 1985. EPA placed the site on the National Priorities List (NPL) in 1984 because of contaminated ground water and soil resulting from facility operations. EPA and the South Carolina Department of Health and Environmental Control (SCDHEC) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. A water line connects residences and businesses to the public water supply. By monitoring ground water and undertaking Five-Year Reviews, EPA and SCDHEC continue to protect people and the environment from site contamination.
The 5-acre site is located on Dixiana Road in the rural community of Dixiana in northeastern South Carolina, approximately one-and-a-half miles southeast of West Columbia, four miles south of Cayce and six miles southwest of Columbia. The site includes the former wood preserving facility and two adjacent areas, which are 3.6 acres and 1.3 acres in size. Undeveloped land borders the site to the north, south and west. Residences border the site to the northeast and east. Site surroundings include single-family homes, which include low-income residents, and light industrial businesses.
From 1963 until 1985, a wood preserving facility operated at the site. In 1984, EPA listed the site on the NPL. When operations ended in 1985, EPA removed all equipment and structures from the site. The site is currently vacant.
Site investigations found contamination in ground water and soil at the site that could potentially harm people in the area. Contamination resulted from wood treating operations at the site. Contaminants of concern include arsenic, chromium and copper.
Investigation and Cleanup Responsibility / Oversight
EPA leads site investigation and cleanup activities in cooperation with SCDHEC.
Site Cleanup Plan
In 1987, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Using a pump-and-treat system to address ground water contamination.
- Discharging treated ground water to the City of Cayce's wastewater treatment plant.
- Digging up and flushing contaminated soil with an acidic water solution.
- Placing treated soil back in dug-up areas and solidifying the soil.
In August 2008, EPA issued a ROD Amendment to change the ground water cleanup plan from a pump-and-treat system to a system involving the injection of nutrients into ground water to enhance the natural breakdown of remaining contaminants.
In 1985, EPA provided a temporary alternative drinking water supply to a residence until a permanent water supply could be provided. EPA also removed all equipment and structures from the site. From 1988 until 1989, EPA dug up, treated, solidified/stabilized, placed on site and covered approximately 12,700 cubic yards of contaminated soil. EPA formed and placed approximately 20 concrete structures made of the solidified/stabilized material on the two on-site areas next to the former wood preserving facility.
EPA completed construction of the ground water pump-and-treat system in 1997. The system operated until 2004 when it shut down for EPA to complete a long-term monitoring study of the aquifer system. In March 2009, EPA implemented an injection treatment system to address ground water contamination. EPA decommissioned the system in October 2009, after ground water met cleanup standards.
SCDHEC began annual monitoring of site wells in 2010.
The site’s third Five-Year Review, completed in 2007, found that while the cleanup remains protective of human health and the environment, institutional controls need to be placed on the site property.
EPA and SCDHEC negotiated legal agreements with Palmetto Wood Preserving Company, the site’s PRP, to investigate and clean up the site. The PRP has not been involved in site cleanup activities. EPA and SCDHEC are using federal and state funds for site cleanup activities.
EPA has worked with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA has conducted a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices, interviews and public meetings.
Annual monitoring of site wells is ongoing.
EPA plans to place institutional controls on the site property.
EPA completed the last Five-Year Review in 2007 and plans to complete the next Five-Year in 2012.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
