|Lusher Street Ground Water Contamination||Elkhart, Indiana|
The site is located within Elkhart, Indiana. The contaminated ground water plume is moving primarily north, towards the St. Joseph River.
The site consists of a ground water plume contaminated with 1,1,1-trichloroethane (1,1,1-TCA), trichloroethylene (also called "TCE"), 1,1-dichloroethylene (1,1-DCE) and some other chlorinated solvents. In 1987 and again in 2006, EPA worked with the State to provide the community with alternate water supplies (municipal water supply line extension or carbon filtration units for the drinking water wells). This action only partially addressed the source(s) and did not address the contaminated ground water. The State and the EPA are working to find a comprehensive solution to the contaminated ground water plume.
The ground water plume is contaminated with 1,1,1-TCA, TCE, and 1,1-DCE. 1,1,1-TCA and TCE are typically used as degreasing agents, parts cleaner, foam plastic blowing agents, and engine cleaner.
Potential Impacts on Surrounding Community/Environment:
Thirty-four drinking water wells are contaminated in the area. Ten drinking water wells were found to exceed U.S. EPA's Maximum Contaminant Level (MCL) for TCE and 1,1-DCE. An additional twenty-four drinking water wells have low concentrations (below the MCL) of chlorinated solvents.
Response Activities (to date):
EPA and the State provided alternate water supplies (municipal water supply line extension or carbon filtration units for the drinking water wells) to residents and businesses in this area in 1987 and again in 2006.
Need for NPL Listing:
Applicable federal and state cleanup programs were evaluated to determine the best program to clean up this site. The State of Indiana referred the site to EPA because a long-term comprehensive solution is needed to protect the private drinking water wells in the area. It was determined that the NPL program provides the best approach to investigate and address all of the source(s) and associated plumes to protect human health and the environment at this site. EPA received a letter of support for placing this site on the NPL from the state.
