Cosden Chemical Coatings was a 6.7 acre paint formulation and manufacturing facility which produced coatings for industrial applications until 1985 and paints until 1989 when all operations ceased. The site is located in a suburban area that has some light industry. In the manufacturing process, pigments were mixed with resins and solvents to produce paints and coatings. Mixing tanks were washed out with solvents, and the rinsate was transferred to drums. As a result of leaking drums and poor operational practices, the soil, groundwater, and process building were contaminated with volatile organic compounds, polychlorinated biphenyls (PCBs), and heavy metals. In addition to an emergency cleanup action, the site cleanup is being conducted in three operable units.
Current Site Status and Cleanup Actions to Date
- In 1989, EPA initiated emergency cleanup activities at the site by constructing a fence around areas of soil contamination, and removing the approximately 600 drums, as well as paint cans, pigment bags, mixing tanks, and underground storage tank (UST) contents at the site. This action was completed in 1990.
- The site has been broken up into three Operable Units (OUs) or cleanup projects.
- OU 1 - In 1996, the building on the site was decontaminated and demolished. The building debris was disposed at an appropriate offsite facility.
- OU 2 - In 2002, soil contaminated with volatile organic compounds, inorganic compounds and PCBs was disposed at an appropriate offsite facility.
- OU 3 - The final cleanup actions planned for the site include the extraction of contaminated groundwater with an onsite treatment and recharge system and the installation of a soil vapor extraction (SVE) (PDF) (80 K, 2 pp) system.
- EPA continues to monitor the site to ensure there is no immediate threat to human health or the environment pending the start of the soil vapor extraction and groundwater pump and treat systems.
Current Funding Status
- EPA previously provided approximately $9.5 million to conduct cleanup work at the site.
- In Fiscal Year 2004, an additional $3 million was obligated to remove the remaining contaminated soil at the site with a soil vapor extraction system and to remove the remaining groundwater contamination with a pump and treatment system.

- Securing the Site with construction of a fence around areas of soil contamination, and the removal of approximately 600 drums, as well as paint cans, pigment bags, mixing tanks, and UST contents in 1990.
- Decontamination and demolition of the building on the site with disposal of the building debris at an appropriate off-site facility was completed in 1996;
- Offsite disposal of approximately 11,000 tons of soil and debris contaminated with volatile organic compounds, inorganic compounds and PCBs was completed in 2002.
- In the past EPA has provided approximately $9.5 million to conduct cleanup work at the site. In Fiscal Year 2004, an additional $3 million was obligated at this site.
