Soil sampling conducted in conjunction with a major PCB contamination removal revealed residential soil lead concentrations equal to or above the EPA Region 4 residential action level of 400 parts per million (ppm).
As a result, EPA has sampled approximately 2,150 properties (residential, parks, school areas, etc;) to access lead contamination. Soil samples with lead levels equal to or above 400 ppm have been identified for removal under this action with priority being given based on a combination of soil lead levels and presence of sensitive receptors such as children and pregnant women.
