Post-remedy Recontamination in Sediments and Floodplain

Gradient reviewed post-remedy data on locations PCBs and DNAPL in brook sediments and the floodplain at a Midwest Superfund site to determine the need for additional remediation. We determined whether the contaminants posed a risk to human health and the environment. Additionally; Gradient evaluated the transport mechanisms responsible for the recontamination of previously excavated areas. Gradient's results were presented to the US E
