Jackson Blvd. Chicago, Illinois 60604 Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin Cleanup Complete at Penta Wood Products Site Town of Daniels, Wisconsin September 2000 Excavation of the infiltration basin at the Penta Wood Site Soil Excavation, Building Demolition Included In Final Cleanup The Penta Wood Products soil and sediment cleanup will be completed this fall. To do this, the United States Environmental Protection Agency (U.S. EPA) conducted the following activities in 2000: • Demolishing all buildings and equipment on site; • Excavating and transferring pentachlorophenol (PCP) and arsenic- contaminated soil to an on-site disposal area; • Clearing trees and brush; • Excavating and transferring woodchips to an on-site disposal area; • Stabilizing arsenic-contaminated soil by mixing it with concrete and placing it in a 7-acre soil cover area; • Constructing a water-treatment system, building and infiltration concrete basin; • Installing pipes for the treatment system; • Installing bioventing and ground-water extraction wells; and • Erecting a fence around the 7-acre soil cover area. Final cleanup activities that will continue through October will include implementing land and water-use restrictions for areas beneath the soil cover area. Native trees and grasses will be planted next spring. ------- SSV10 ISdld t(l<;n<; p.u: \."i[i '\\ :_:_ ooe$ asn 34BAUJ joj X}[cu8j 'ssainsng Vd3 Once complete, U.S. EPA will have spent about $7.5 million on the project. It was only one of about 10 Superfund sites nationwide to receive cleanup monies this year. The Penta Wood site was considered a high priority because of the possibility of contaminated soil and ground water moving off site and because of the health risk associated with touching contaminated soil or drinking PCP or arsenic-contaminated ground wa- ter. Background U.S. EPA selected the Penta Wood cleanup plan in 1998. The plan included consolidating contaminated soil and sediment and bioventing. Bioventing is a process that blows air into the ground to speed up the breakdown of PCP-contaminated soil. The use of ex- traction wells to remove contaminated ground water for treatment was also part of the cleanup plan. Penta Wood Products operated the site, 3 miles west of Siren on Daniels 70 in the Town of Daniels, as a wood treatment facility from 1953 to 1992. The company treated wood posts and telephone poles with a PCP solution in fuel oil or with a water-borne salt treatment consisting of ammonia, copper II oxide, zinc and ar- senate. Over the years, PCP/oil-contaminated waste- water was discharged into a lagoon and onto a woodchip pile on site. Contaminants were found in site soil and ground water in 1994. After eliminating immediate threats to people and the environment, U.S. EPA placed the site on its Superfund list to clean up long-term problems, such as ground-water contamina- tion. ------- |
