Superfund areas have contaminated water, air, soil, and/or living organisms. Some areas are being monitored, some have been cleaned up to the best of our abilities, some have no intervention due to lack of funds/etc. Some of these areas aren’t well contained and still leach into surrounding air/soil/water for miles.

Idaho: 6 sites
Illinois: 44 sites — Highest score area: 70.71 DePue/New Jersey Zinc/Mobil Chemical Corp. in the Village of DePue, Bureau County, Illinois. Contaminant souces include a residue pile, a waste pile, lithopone waste material ridges, a cinder fill area, contaminated soils, lagoons/cooling ponds, and gypsum stack ponds. All of the sources were found to contain elevated levels of metals, including zinc, lead, arsenic, cadmium, chromium, and copper. Elevated levels of cadmium were found in residential soil samples. In addition, contamination of a fishery, state wildlife refuge, and wetlands have been documented in Lake DePue.
Indiana: 34 sites
Iowa: 11 sites
Kansas: 12 sites
Kentucky: 14 sites
Louisiana: 9 sites

Maryland: 20 sites
Massachusetts: 32 sites — Highest score area: 72.42 250 acres in North Woburn, Massachusetts has over 170 years’ accumulation of industrial by-products and wastes. Many of the pits, piles, and lagoons are continuously leaching toxic metals into the environment.
Michigan: 65 sites
Minnesota: 25 sites
Mississippi: 8 sites
Missouri: 33 sites — Highest score area: 84.91 BIG RIVER MINE TAILINGS/ST. JOE MINERALS CORP. Desloge, Missouri approx 110 square miles. St. Joe Minerals Corp. who operated at the site, disposed of lead, cadmium, and zinc-rich mine tailings over approximately 600 acres in a rural area bordered on three sides by Big River. The air, water, soil, and living organisms have been contaminated. Missouri has numerous sites that score 70 or higher. They appear to be along an area called the “lead belt” which produced over 80% of all lead for the US. The EPA provides bottled water to many residences in this area. Sampling data has indicated elevated levels of lead, cadmium, barium, and arsenic in soil, surface water, and ground water. Hundreds of wells are contaminated.
