More environmental concerns are being raised in the Gulf Coast region. The magazine Solid Waste & Recycling reports that New Orleans may be facing a dramatic pollution issue related to a 95-acre toxic landfill site in downtown New Orleans that is still underwater. The landfill is a federally registered Superfund site and is considered highly contaminated requiring cleanup and containment. The flood has increased the chances that the toxic waste in the landfill could leach out and contaminate the surrounding area. Two Superfund sites in neighboring Mississippi may also have sustained water damage. According to the Washington Post, the flooded Superfund sites contain a range of contaminants that include heavy metals linked to increased cancer risk and developmental problems as well as other carcinogens.
