Current Site Status
Royal Adhesives & Sealants operates the Para-Chem Southern facility. EPA continues to refer to the Superfund site as Para-Chem Southern, Inc. for regulatory purposes. Para-Chem Southern, Inc. (now Royal Adhesives & Sealants) has operated at the facility since 1965. EPA placed the site on the National Priorities List (NPL) in 1990 because of contaminated ground water, soil and surface water resulting from facility operations. EPA, the South Carolina Department of Health and Environmental Control (SCDHEC), and the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. A water line connects the on-site facility to the public water supply. Site contamination does not currently threaten people living and working near the site. By treating and monitoring ground water, placing institutional controls on the site property, and undertaking Five-Year Reviews, EPA, SCDHEC and the site’s PRP continue to protect people and the environment from site contamination.
The 134-acre site is located on Highway 14 between Simpsonville and Fountain Inn, South Carolina. The site includes an active manufacturing facility (Royal Adhesives & Sealants), associated structures, paved parking areas, a grass-covered field, forested areas and an unnamed tributary of Durbin Creek. Residential land uses border the site to the southeast, east and north. Bryson Elementary School and Golden Strip Learning Center are located east of the Site, and a road borders the site to the west and northwest. New residential development is occurring near the site and current growth of the community suggests there will be further development of land surrounding the site. The site’s broader surroundings include a mix of industrial, residential and commercial land uses.
Since 1965, Para-Chem Southern, Inc. (now Royal Adhesives & Sealants) has operated a manufacturing facility at the site. Operations include production of acrylic polymers, thickeners, latex coatings and adhesives for consumer and industrial applications. From 1975 to 1979, operators buried industrial wastes in three areas on site. Until 1984, operations also discharged wastewater into two unlined ponds on site. In 1985, Para-Chem Southern, Inc.notified EPA and SCDHEC of the three waste areas on site. During 1985, two 3,515-gallon spills occurred west of the facility’s production area. The spills remained within the site boundary. In 1990, EPA listed the site on the NPL. In 1997, Para-Chem Southern, Inc.purchased additional land, which EPA considers part of the site. Following cleanup activities, EPA deleted parts of the site from the NPL in 1997.
The site’s zoning is for industrial uses and the manufacturing facility continues to operate on site. Fencing limits access to the site property.
Site investigations found contamination in ground water, soil and surface water that could potentially harm people in the area. Contamination resulted from manufacturing operations at the site. Contaminants of concern include polycyclic aromatic hydrocarbons (PAHs), base neutral acids, metals and volatile organic compounds (VOCs).
Contamination affected ground water, soil and surface water both on and off site. An estimated 1,500 people obtain drinking water from private wells within three miles of the site and the nearest well is located within one mile of the site. However, there are no private wells located within the area of ground water contamination. A water line connects the manufacturing facility on site to the public water supply.
Bryson Elementary School and Golden Strip Learning Center as well as residential areas are located upgradient from the site and not affected by site contamination.
Investigation and Cleanup Responsibility / Oversight
Para-Chem Southern, Inc. (now Royal Adhesives & Sealants), the site’s PRP, leads site investigation and cleanup activities, with oversight provided by EPA and SCDHEC.
Site Cleanup Plan
In 1993, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities.
- Digging up contaminated soil.
- Sampling remaining soil to confirm the removal of contamination.
- Using living organisms to break down contaminants in soil (also known as bioremediation).
- Disposing soil containing non-biodegradable contaminants at an off-site facility.
- Treating contaminated soil before disposal to meet off-site facility disposal restrictions.
- Extracting contaminated ground water.
- Treating contaminated ground water using air stripping to remove contamination from ground water.
In 1999, EPA issued an amendment to the cleanup plan (a ROD Amendment) to address two additional areas of contamination. The amended cleanup plan included the following activities:
- Implementing a soil vapor extraction system to address contaminated soil.
- Modifying the soil’s performance standards.
- Expanding the site’s ground water extraction and treatment system.
- Discharging treated ground water into a ditch on site.
In 1987, the site’s PRP removed approximately 3,000 tons of drums, waste materials, soil and debris from four former waste disposal areas on site.
The PRP completed investigation of the site in 1993.
In 1996, the PRP removed an additional 18,607 tons of contaminated waste from the site. The PRP completed upgrades to the site’s existing ground water extraction and treatment system in 1998.
In 2000 and 2001, the PRP conducted additional construction and installed additional wells.
The soil vapor extraction system operated during 2000 and 2001 until soil met site cleanup goals.
In 2006 and 2007, the PRP made operational changes to the ground water extraction and treatment system.
The site’s second Five-Year Review, completed in 2010, found that the ground water extraction and treatment system continues to remove and treat contaminated ground water. Further, no drinking water wells are in the area of contamination. The Five-Year Review also recommended that the PRP conduct additional investigation work to confirm the system’s effectiveness in reaching ground water cleanup goals.
Several recent activities have recently been completed or are currently underway. The groundwater treatment system has been modified to include oxidation treatment to eliminate 1,4-dioxane from treated groundwater. The on-site pond was sealed and the discharge point for treated groundwater has been changed from the pond to the creek (unnamed tributary to Durbin Creek). A direct push investigation has been completed and has resulted in the discovery of additional sources of contamination, including near the production facility and under the production facility. The capture zone of the groundwater extraction system is under investigation. Several of the extraction wells have been repaired to eliminate air entrainment. Additional sampling has confirmed that no contamination exists east of the creek, and the institutional controls are being adjusted to ensure that all contaminated area is subject to groundwater and soil institutional controls, and the institutional controls are removed from areas that are not contaminated. The goal is to optimize the groundwater remedy in order to improve the efficiency and effectiveness of the remedy. Additional source removal is anticipated. Changes in the groundwater extraction system are anticipated.
EPA negotiated legal agreements with the site’s PRP to investigate and clean up the site. The PRP continues to fund site cleanup, monitoring and oversight 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.
The site’s PRP continues to conduct ground water extraction and treatment system operations, semi-annual sampling and monitoring.
EPA and SCDHEC are working with the PRP to evaluate the effectiveness and efficiency of the current ground water extraction and treatment system, and to determine if the PRP should modify the system to optimize its effectiveness. The PRP is modifying the existing ground water treatment system to address additional contaminants of concern. Parties are also investigating additional potential source areas.
EPA completed the last Five-Year Review in 2010 and plans to complete the next Five-Year Review in 2015.
