The U.S. Environmental Protection Agency announced on May 15 that seven sites have been added to the Superfund National Priorities List. All seven involve groundwater contamination.

The sites and its groundwater issues are:

  • McLouth Steel Corp. in Trenton, Michigan. Hazardous waste in leachate is contaminating groundwater.
  • Sporlan Valve Plant #1 in Washington, Missouri. Tank leaks have released TCE, benzene, vinyl chloride, and 1,1-DCE into groundwater.
  • Magna Metals in Cortlandt Manor, New York. Iron, lead, copper, nickel, zinc chlorides, cyanides, and sulfates were discharged to a series of leaching pits contaminating groundwater.
  • PROTECO in Peñuelas, Puerto Rico. A landfill is leaching mercury and solvents into the groundwater.
