7400 W 15TH AVE

The 7-acre Midco I Superfund site is located at 7400 West 15th Avenue in Gary, Lake County, Indiana. The site is currently fenced and contains a groundwater treatment plant plus a contaminant source area and areas of contaminated sediment. The Midco I site was used to store, recycle, and dispose of industrial wastes from 1973 to 1979. In December 1976, a large fire destroyed an estimated 14,000 55-gallon drums of chemical wastes, resulting in spillage. Operations were resumed in October 1977. When the site was abandoned in 1979, thousands of full drums of waste were left behind in addition to the fire-damaged drums. There are a number of small businesses located within 1,000 feet of the Midco I site. A residential neighborhood of Hammond, Indiana, is located within 1,500 feet and a residential neighborhood of Gary is located 3,000 feet from the site. Several private drinking water wells were found to have been drawing water from the same aquifer beneath the site and were located in the direction of off-site groundwater flow. Site Responsibility The Midco I site is being addressed by a combination of federal and state actions and federal and state oversight of potentially responsible party (PRP) actions.
