The Tuchman Cleaners Site is located at 4401 N. Keystone Avenue in Indianapolis, Marion County, Indiana, 46205. The Site is located in an area that is commercial and residential. Approximately 10,000 people live within one mile of the Site. The Fall Creek well field is less than ¼ mile from the Site. Fall Creek, a major tributary to the White River, is located approximately 500 feet south of the Site.

Historical data documented volatile organic compounds (VOC), including chlorinated solvents, in soil and groundwater at the Site. Several VOCs, including tetrachloroethene (PCE) and trichloroethene (TCE), were detected above the Indiana Department of Environmental Management (IDEM) Risk Integrated System of Closure (RISC) industrial levels. PCE was detected in near-surface soil at a maximum concentration of 2,400 milligrams per kilogram (mg/kg) at 1 foot below ground surface. In July 2007, PCE was detected in groundwater at a maximum concentration of 135 milligrams per liter (mg/L) in monitoring well MW-2i.
In September 2012, EPA began a time-critical removal action that included removing soil that poses a direct contact threat; backfilling excavated areas; conducting vapor intrusion assessment and mitigation; and transportation and disposal off-site of hazardous substances, pollutants and contaminants.
