  • Superfund Investigates Land Pollution from the Past…and Present

    On September 7, 2016, we took steps to respond to states, tribes and citizens who asked for our help addressing contaminated sites. In response, we are adding 10 hazardous waste sites to the National Priorities List (NPL). The NPL is our list of more than 1,300 of the most contaminated sites in the country that we are addressing under the Superfund program. Superfund is one of the most important ...

  • Influence of a chlor‐alkali Superfund site on mercury bioaccumulation in periphyton and Low‐trophic level fauna

    In Berlin, NH, the Androscoggin River flows adjacent to a former chlor‐alkali facility that is a US EPA Superfund site and source of mercury (Hg) to the river. A study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic‐level taxa in the river. Surface sediment directly adjacent to the source showed significantly elevated MeHg (10–40x increase, ...

  • Treatment of Dense Non-Aqueous Phase Liquids Through Enhanced Bioremediation

    ProblemAs a result of trichloroethene (TCE) releases to groundwater during the 1960’s, TCE is now found in the sandy aquifer beneath the Site in the form of a dense, non-aqueous phase liquid (DNAPL). Testing for the vinyl chloride reductase (vcrA) gene (Gene-Trac-VC) and bench scale treatability testing indicated that native Dehalococcoides (Dhc) found at the Site were not uniformly capable of ...
