| Abstract |
The Ninth Avenue Dump is a 17-acre, inactive chemical and industrial waste disposal site in Gary, Indiana. There is industrial, commercial, and residential development in the surrounding area. Hazardous waste disposal occurred at the site from the early to mid-1970s, with some filling associated with cleanup activities continuing until 1980. A State inspection in 1975 revealed that there were approximately 10,000 55-gallon drums at the site. Additionally, the State estimated that 500,000 gallons of liquid industrial waste were dumped, and 1,000 drums were buried onsite and in contact with ground water. As a result of 1975 state orders and 1980 EPA orders to initiate surface cleanup, the site operator removed drums, tank cars, and some contaminated soil from the site's surface. The selected remedial action for the site includes excavating approximately 36,000 cu yds of the most severely oil-contaminated waste onsite thermal treatment of excavated waste, fill, and previously extracted oil; covering the area contained by the slurry well with a RCRA cap; pumping and treatment of ground water inside the slurry wall. |
