USA - Blackhawk Foundry agrees to clean up Iowa facility

U.S. Environmental Protection Agency Region 7 and Blackhawk Foundry and Machine, of Davenport, Iowa, have reached an agreement that requires the company to address the presence of lead contaminated soils at its facility at 323 South Clark Street in Davenport. The specific requirements are outlined in an Administrative Order filed today in Kansas City, Kan.

The agreement requires Blackhawk to excavate and properly dispose of lead contaminated soil. Blackhawk will then construct a gravel cap over the excavated area. The cap will ensure that remaining soil does not run off during rainfall and flood events and that any contaminated dust does not fly away during dry and windy conditions.

EPA also requires Blackhawk to prevent future land uses of the facility that would cause unacceptable exposure to contaminated soil. There should be no residential use of the property without cleanup to EPA-approved residential standards (400 parts per million).

In any subsequently issued property deeds, Blackhawk must also identify the location of surface impoundments and prevent installation of water supply wells. EPA will monitor the effectiveness and protectiveness of the excavation and the institutional controls.
