Ground-water data for Michigan 1989

Abstract

Water levels, locations, depths, and aquifers tapped are given for 108 observation wells. Tabulated data include a listing of groundwater reports in Michigan, extremes of water levels for calendar year 1989 and for the period of record, pumpage of most major groundwater users in the State, and water-quality data from selected wells. In 1989, 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 6.7 billion gallons from glacial deposits only. GroundWater Records and Reports Tabulations of water-level measurements, hydrographs of observation wells, 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. They can be

“…For 2001, data were averaged using available data from 1997 to 2001. For other communities within the study area, withdrawals were estimated using data supplied by municipal suppliers and included in annual ground-water data reports prepared by the USGS from 1970 to 1990 Thompson, 1971, 1973;Huffman, 1974a-88;Huffman and Whited, 1988;1989;1991;1993) or previous studies of this area others, 1972 andRheaume, 1990).…”
