Full Description

In late 1980 the Michigan Department of Public Health instituted a routine, statewide trihalomethane monitoring program. As a result, unacceptable levels of tetrachloroethylene were discovered in a portion of the city of Kalamazoo's water distribution system and in one of the city's well fields. Sequential test wells were drilled to identify the source of contamination and to plot its movement through the aquifer. In addition, a land-use study was conducted as well as a study of the theoretical piezometric surface. Initially, the two most contaminated production wells were used as purge wells. This practice proved beneficial in protecting the remainder of the well field from further increases in tetrachloroethylene. Therefore, the practice continues to be used. The source of the contamination was identified to be an abandoned dry cleaning business. An ongoing monitoring program tracks the progress of the contaminant. Includes 6 references, tables, figures.
