We propose to sample and analyze leachate from and groundwater near the Eastham MA landfill for perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perchlorate, and 1,4-dioxane. The Environmental Protection Agency (EPA) lists these chemicals as contaminants of concern or emerging contaminants that are known or suspected to have serious health effects. After initial site characterization, the fate and transport of these groundwater contaminants will be characterized using the Hydrocarbon Spill Screening Model (HSSM) and novel remediation methods such as using an electrochemical carbon nanotube (CNT) filter as a landfill liner will be evaluated.
