Lower Darby Creek on EPA's National Priority List for Clean-Up
The incinerator, municipal dumps and sludge farm are long closed, and the oil tank farm with its refinery wastes has been inactive since the 1950's. But the waters of Lower Darby Creek remain hazardous to fish and wildlife: heavy metals, polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), and polychlorinaed biphenyls (PCBs) are unwelcome reminders of the area's industrial past. This sign, posted within Tinicum National Wildlife Refuge (now John Heinz NWR), warns people of the danger of eating the contaminated fish. In June 2001, the EPA included the site on its national priority list (NPL) and will be conducting comprehensive environmental sampling of the area.
