Cleanup remedies at five Long Island hazardous waste sites "continue to be effective in protecting human health," the U.S. Environmental Protection Agency said this week, though some of the toxic areas need continued monitoring.
The agency conducted the federally mandated reviews at Superfund sites located in Glen Cove, Port Jefferson Station, Franklin Square and East Farmingdale. Across New York, New Jersey and Puerto Rico, 32 federal Superfund sites were appraised, which happen every five years, the EPA said.
