In response to the reauthorization of the Safe Drinking Water Act of 1996, the United States Geological Survey and the Michigan Department of Environmental Quality are cooperatively assessing the safety of public water supplies from inland rivers, the Great Lakes, and the Great Lakes connecting channels. Assessments to identify activities that could adversely impact water quality will use local data on land use and contamination sources (sewer outfalls, leaking storage tanks); information from water plant personnel (influent chemistry, effects of weather, lake currents); and centralized state and federal data resources (census data, permitted discharges). Assessment of 60 Great Lakes and 13 connecting channels supplied systems will follow the "Assessment Protocol for Great Lakes Sources" developed by the Great Lakes States in United States Environmental Protection Agency Region 5. Assessments of nine river-supplied systems will be based on a modification of the "Assessment Protocol for Great Lakes Sources", an inventory of contaminants of concern, identification of potential contamination sources, and determination of susceptibility to contamination.

Learning Objectives: At the conclusion of the session the participant will be able to describe Michigan's source-water assessment program for public surface-water supplies.
