Ground-water Data for Michigan - 1984
Groundwater ; Wells
Water levels, locations, depths, and aquifers tapped are given for 114 observation wells. Tabulated data include extremes of water levels for 1984 and for the period of record, pumpage of most major ground-water users in the State, and water-quality data from 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.
This report makes available, through 1984, the records of water levels and related data for the principal aquifers of the State. 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 water-quality data from selected wells sampled during 1984 are given in tables 1, 2, and 3. Distribution of observation wells is shown in figure 1. Location of wells sampled for water-quality data and years sampled are shown in figure 2.
