LONG PRAIRIE CITY LIMITS
The Long Prairie Groundwater Contamination Site is a 7,000 square-foot source area underlain by a one-half mile long groundwater plume, located in Long Prairie, Todd County, Minnesota. The contaminant plume originates in the commercial area of Long Prairie and extends through an older residential area of the city. The Site is also located in the downtown commercial district of Long Prairie. The city of Long Prairie is a community of less than 3,000 residents, only a few of whom still have private wells. About 350 homes supplied by private wells were affected by the groundwater contamination until municipal water main extensions and service connections were provided. The site was discovered in 1983 during the Minnesota Department of Health's (MDH) statewide VOC analysis of public water supplies. The state's investigation identified the source of contamination to be a dry-cleaning facility at 243 Central Avenue, which operated from 1978 until mid-1984. Improper waste disposal of the dry-cleaning solvent tetrachloroethylene (PCE) and related sludges from the facility resulted in the eventual migration of volatile organic chemicals (VOCs) to the soil and groundwater. The municipal water supply of Long Prairie was found to be contaminated with PCE and its degradation products, trichloroethylene (TCE), cis-1,2-dichloroethylene (DCE), and vinyl chloride (VC). The Environmental Protection Agency (EPA) placed the site on the National Priorities List (NPL) on June 10, 1986. Site Responsibility This site is being addressed through federal and state actions.
