(2/10/06) On Feb. 3, 2006, EPA posted additional data from samples taken at the DuPont-DeLisle plant in Bay St. Louis, Miss. EPA compared samples with sampling conducted before Hurricane Katrina to determine whether the site was impacted by Hurricane Katrina.

Five locations were resampled and analyzed only for dioxin/furans. None of the three surface soil samples exceeded residential preliminary remediation goals (PRGs) in the vicinity of the residential development. One of the two sediments samples exceeded the industrial PRG.

Original samples were analyzed for volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), pesticides/PCBs, and metals. Low levels of metals, VOCs, pesticides, and SVOCs were detected in samples and no PCBs were reported.

Based on these sampling results, EPA does not believe the site was impacted by Hurricane Katrina.
