This is a list of Superfund sites in Indiana designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.[1] These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation.[2] As of June 29, 2022, there have been 53 total Superfund sites on the National Priorities List in Indiana.[2] No additional sites are currently proposed for entry on the list.[3] Thirteen sites have been cleaned up and removed from the list.[4]
Concentrations of chlorinated volatile organic compounds at or above the Safe Water Drinking Act’s Maximum Contaminant Levels found in three municipal wells used for drinking water in Anderson.[8]
A variety of chlorinated compounds, including TCE and carbon tetrachloride escaped into the local aquifer as a result of accidents and other releases at this site. Groundwater contamination formed two distinct plumes migrating to the St. Joseph River.[13]
Chromium, cadmium, arsenic, lead, and iron constituents known to be in the impoundment, in on-site ground water. PCB, Vinyl Chloride, Benzofluoranthene.[14]
Unlined landfill in Mishawaka at Douglas and Grape Roads included solvents, fly ash, paper, wood stock, rubber and plastic wrap leading to soil and groundwater contamination.[15]
North of Zionsville, site contains resins, paint sludges, waste oils and flammable solvents stored in drums and storage tanks. Soil and groundwater were contaminated.[17]
Landfill site in the floodplain of the Maumee River contaminated soil with volatile organic compounds, heavy metals, PCBs, and polycyclic aromatic compounds.[19]
Allegedly, wastes were incinerated on-site. No records were kept of the types or quantities of wastes received. Of primary concern are large quantities of exposed capacitors containing PCBs.[32]
The largest well field owned by Elkhart, containing 70% of the city's drinking water, groundwater is contaminated with volatile organic compounds such as TCE.[34]
RCA, Bragg Construction Company, and Waste Reduction Systems combined to release 1.1 million cubic yards of wastes, including hazardous solvents, plasticizers, lead, and cadmium.[35]
After 14,000 drums of hazardous wastes burned in a 1976 fire, thousands of drums of hazardous waste were left at the facility following its abandonment in 1979. Soil, sediment, surface water and groundwater were contaminated.[36]
An estimated 50,000-60,000 drums of hazardous wastes were destroyed in the 1976 fire, which stored waste solvents, neutralized acids and caustics, and dumped waste. Soil and groundwater were contaminated.[37]
Former disposal site for industrial wastes produced by Westinghouse Electric, including electrical capacitors containing PCBs, capacitor parts, PCB-contaminated rags and sawdust, contaminating groundwater.[38]
Capacitors and arrestors containing PCBs, as well as PCB-contaminated capacitor insulation material, rags, and filter clay, were disposed of at the landfill by Westinghouse Electric.[39]
70-acre site along St. Joseph River contains volatile organic compounds. Five of 47 residences on site exceeded Safe Drinking Water Act Maximum Contaminant Levels.[42]
38-acre groundwater plume is contaminated with PCE and other chlorinated solvents, affecting one of Martinsville's municipal drinking water wells, serving 15,000 people.[44]
Prestolite Battery facility manufactured lead-acid batteries for the automotive industry, contaminated soil with lead and PCBs. Additionally contaminated groundwater, sediment and surface water with volatile organic compounds.[46]
A still active solid waste disposal facility, an estimated four million cubic yards of hazardous waste, including coal tar, asbestos, iron oxide and clarifier sludges, and paint waste, were buried, leading to soil and groundwater contamination.[49]
Lafayette landfill, which includes a wetland, contains 3.4 million cubic yards of solid waste, including industrial sludge with elevated levels of PCBs.[50]
Listed in 2009 on the NPL as one of the most contaminated sites in the country, the site includes parts of the former USS Lead facility and commercial, municipal and residential areas in East Chicago. The site's primary concerns are lead and arsenic.[52]
Wayne Waste Oil, a division of Wayne Reclamation and Recycling, Inc., deposited about one million gallons of oil-related wastes on site. Waste disposal operations contaminated soil and groundwater with hazardous chemicals.[54]
Used electrical equipment, including capacitors and transformers containing polychlorinated biphenyls, were stored at the Lebanon Wedzeb site. Water from a 1981 fire leaked into a sanitary sewer line.[55]
A truck washing and leasing company operated on site in South Bend. Detergents and solvents used by the operation were discharged to three dry wells on site, contaminating soil and groundwater with hazardous chemicals.[56]
