Third Five-Year Review to Begin, E. I. du Pont de Nemours and Company Superfund Site, (DuPont - County Road X-23), Lee County, Iowa
The U.S. Environmental Protection Agency conducts regular five-year reviews on Superfund sites where cleanups have been completed. These reviews are required by the Superfund law [42 U.S.C. Section 9621 (c)]. EPA Region 7 and the Iowa Department of Natural Resources have initiated their third five-year review of the E.I. du Pont de Nemours and Company (DuPont- County Road X-23) Superfund Site in Lee County, Iowa.
The Site consists of the Baier and McCarl subsites and is located approximately 3.5 miles south of West Point, Iowa.
From 1949 through 1953, an estimated 48,000 to 72,000 55-gallon drums of waste from DuPont's paint manufacturing plant in Fort Madison, Iowa were disposed at the two subsites. In addition to drummed wastes, paint waste was placed in trenches and burned. The Baier subsite was the primary disposal area; however, during inclement weather when the Baier site was not accessible, wastes were disposed at the McCarl subsite. Volatile organic compounds and metals contamination were found at the subsites.
Under EPA oversight from 1992 to 1993, DuPont excavated contaminated soil from both subsites and utilized a process of stabilization/solidification to treat the soil before placing all the treated soil into the excavated area at the Baier subsite. The treated soil was then covered with clean soil and grass. The Baier subsite was fenced to keep people off the site and to protect the cover. Restrictions were placed on both subsites to limit the land uses. DuPont continues to maintain both subsites.
EPA and the Iowa Department of Natural Resources will study site information during this third five-year review and inspect the site to determine if the remedy continues to protect human health and the environment. EPA and the state encourage members of the community to ask questions and report any concerns about the site.
A final report will be prepared at the end of the review and will be available at the site information repositories.
