Ground-water data for Michigan 1990

Abstract

Water levels, locations, depths, and aquifers tapped are given for 107 observation wells. Tabulated data include a listing of ground-water reports in Michigan, extremes of water levels for calendar year 1990 and for the period of record, pumpage of most major ground-water users in the State, and a map showing previous collected water-quality data from selected wells. In 1990, the two largest municipal users of ground water were Lansing and Kalamazoo. Lansing pumped 7.2 billion gallons from the Saginaw Formation and glacial deposits; Kalamazoo pumped 7.0 billion gallons from glacial deposits only. Ground-Water Records and ReportsTabulations and compilations of water-level measurements, hydrographs of ground-water wells, results of chemical analyses, water-temperature measurements, well records and logs, aquifer tests, records of pumping for public and industrial supplies, and water-resources reports are on file for public inspection.

Estimation of groundwater use for a groundwater-flow model of the Lake Michigan Basin and adjacent areas, 1864-2005

Some historical groundwater-withdrawal data from 1970 to 1990 have been supplied by public water-supply systems for annual groundwater-data reports prepared by the USGS Thompson, 1971, 1973;Huffman, 1974aHuffman, , 1974bHuffman, , 1979aHuffman, , 1979bHuffman, , 1988, 1991, 1993. Additional data were available from previously published reports, including those by the Michigan Department of Public Health (1943), the Michigan Department of Health (1961), Bedell (1982), Baltusis and others (1992), Holtschlag and others (1996), Luukkonen and Westjohn (2001), and Luukkonen and others (2004).…”
