The purpose of this study was to evaluate the potential effectiveness of proposed artificial recharge basins at the Garden Lane Well Field in Portage, Michigan. The area is underlain by 7 feet of muck, 27 feet of sand and gravel, and a 10 foot semiconfining till over a semiconfined aquifer.
The vertical permeability of the semiconfining layer, and the hydraulic head difference between the upper unconfined aquifer and the lower semiconfined aquifer were determined. This was accomplished by conducting a constant-rate pump test. Test data were interpreted by three methods: (1) drawdown vs. time (both logarithmic and semilogarithmic), (2) recovery vs. time, and (3) drawdown vs. distance.
Vertical permeability of the semiconfining layer was determined to be 1.617 gpd/ft2. The hydraulic head difference between the aquifers was found to be 4.09 feet. Calculations indicate that construction of the basin would increase vertical recharge from 162 gpm to only 280 gpm when pumping at 1000 gpm.
