EPA v. ANSUL INCORPORATED

Case summary

Administrative Order on Consent (AOC) Signed for the Ansul, Inc. Site in Marinette, WI An Administrative Order on Consent (AOC) between Ansul, Inc. and the EPA was signed on February 26, 2009 to implement the remedy that was selected last year. Significant arsenic contamination exists in soil, ground-water, and adjacent Menominee River sediment. The highest arsenic concentrations have reached 10,000 ppm or more. The remedy consists of 4 major parts: 1. cap contaminated soils on and off-site; 2. prevent the migration of contaminated groundwater into the Menominee River by constructing 7,000 linear feet of containment barrier wall to surround the site; 3. remove about 75,000 cubic yards of river sediment with arsenic concentrations in excess of 50 ppm; and 4. implement a 10-year period of monitored natural recovery in order to achieve a long-term cleanup goal of 20 ppm in river sediments
