The U.S. Environmental Protection Agency announced 10 new Superfund sites Wednesday, including one in Indianapolis.
A contaminated ground water plume in the west central part of the city contains high levels of vinyl chloride.
The EPA is considering adding a site in Kokomo to the federal list of Superfund sites, which are deemed a threat to public health.
Groundwater from a contaminated site will have to be pumped out and treated for about 30 more years to remove chemicals.
Indiana is requesting Martinsville's wells be added to the Superfund National Priorities List so the city can receive federal assistance.
The new facility manufactures poly-tetra-flourine-ethelyne, which is used as a non-stick coating on many Cook products.
