Ground-water Data for Michigan - 1982
Subject
Groundwater; WellsAbstract
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 ground-water users in the State, and quality data on
selected wells. The largest reported user of ground-water, the
city of Lansing, pumped 8.2 billion gallons from the Saginaw
Formation and glacial deposits.
Description
Data on yield of wells, pumpage, quality of water, and
trends of ground-water 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 ground-water 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.
