Contamination of groundwater, sediments and surface water in the Indian River and Island Creek by a coal ash landfill on Burton Island. Levels of arsenic, chromium, and thallium in on-site groundwater exceeded federal primary drinking water standards (“maximum contaminant levels” or “MCLs”). Off-site concentrations of aluminum and iron in Island Creek exceeded EPA water quality criteria. Levels of aluminum, antimony, arsenic, barium, chromium, iron, manganese, selenium, thallium, and vanadium exceeded Delaware Uniform Risk-Based Standards (URS). Average concentrations of arsenic exceeded the URS in soil/ash; groundwater; shoreline sediments and surface water.
