Ground-water data for Michigan 1982

Abstract

Water levels, locations, depths, and aquifers tapped are given for 117 observation wells. Tabulated data include extremes of water levels for 1982 and for the period of record, pumpage of most major groundwater users in the State, and quality data on selected wells. The largest reported user of groundwater , the city of Lansing, pumped 8.2 billion gallons from the Saginaw Formation and glacial deposits. INTRODUCTION Purpose This report makes available, through 1982, the records of water levels and related data for the principal aquifers of the State. It is written for municipalities, industries, institutions, consultants, drillers, hydrologists and other people interested in groundwater resources. Scope Data on yield of wells, pumpage, quality of water, and trends of groundwater levels for the past 5 years are shown in the text. Many hydrographs are included to illustrate changes in water levels. Records of water levels in observation wells, records of pumpage by most major groundwater users, and waterquality data from selected wells sampled during 1982 are given in tables 1, 2, and 3. Distribution of observation wells is shown in figure 1. Locations of wells selected for collection of water-quality samples and years sampled are shown in figure 2.

Model Refinement and Simulation of Groundwater Flow in Clinton, Eaton, and Ingham Counties, Michigan

“…For communities within the study area, data on withdrawals from 1970 to 1990 were primarily based on records furnished by municipal suppliers, published in annual data reports of the USGS Thompson, 1971, 1973;Huffman, 1974aHuffman, , 1974bHuffman, , 1975Huffman, , 1976Huffman, , 1977Huffman, , 1979aHuffman, , 1979b1980;1981;1982;1983;1984;1986;1988;Huffman and Whited, 1988;1991;1993), or included in previous studies of the area. Additional data are available in a report by Baltusis and others (1992), who summarized sources and annual withdrawals of groundwater for communities in the Lower Peninsula of Michigan.…”

Hydrologic provinces of Michigan

“…Province boundaries were adjusted by overlaying maps of Quaternary geology by Martin (1955Martin ( , 1957a and Farrand and Bell (1984) and delineating additional principal glacial-deposit aquifers on maps of thickness by Passero and others (1981); and maps of yield by Twenter (1966b). Province boundaries were further readjusted on the basis of analyses of ground water from 354 wells sampled by the U.S. Geological Survey from 1977 through 1988 (Huffman, 1978(Huffman, -86, 1988Huffman and Whited, 1988;Dannemiller and Baltusis, 1990). Areas were identified where ground water contained high dissolved-solids concentrations or where major differences in the natural ground-water quality were noted.…”
