For the sites above, the EPA selected a clean-up level based on a target PCB concentration in sediments after removal action was taken. The Fields Brook, Ohio, and New Bedford Harbor are the top two contaminated sites, but they are dramatically different. New Bedford Harbor contained 900,000 cubic yards of sediment at PCB‐contamination levels of up to 10,000 parts per million. The Fields Brook is 53,000 cubic yards with maximum PCB‐contamination levels of 610 ppm. Fields Brook also is a relatively small site in active industrial use, which bears little, if any, resemblance to the complexity of residential, recreational, commercial and industrial land uses surrounding New Bedford Harbor.
