The Pine River, which borders the main plant site on three sides and was known to contain significant levels of DDT and PBB was not required to be remediated by the 1982 Consent Judgment. The Pine River contamination was addressed by the state of Michigan with a no consumption advisory for all species of fish. The fish advisory continues to remain in effect. This site is being addressed through Federal, State, and potentially responsible parties' actions. On-site soil samples revealed contamination with pbbs, copper, chromium, zinc, and magnesium.
Potential risks exist for people who eat contaminated fish and wildlife in the vicinity of the site.
Cleanup Progress Velsicol completed the construction of the containment system at the main plant site in 1985. The containment system consists of a slurry wall around the fifty-four acre site and a clay cap over the site. The Consent Judgment also required that Velsicol maintain water levels within the containment system at less than 724.13 feet above mean sea level. Water levels within the containment system did not exceed 724.13 until 1993. In early 1994, Velsicol had to pump out 1.25 million gallons of water from the containment system.
