Abstract

The purpose of this study was to determine the hydraulic connection between the upper and lower confined glacial drift aquifers. The results of this study are based primarily upon the geologic profiles, a comparison of the head differences within each aquifer, potentiometric surfaces and different lag times for precipitation to reach each aquifer.

Results of the aquifer test showed that the upper confining layer pinches out in the western part of the well field. This area also provided significant recharge to the well field during the aquifer test. Data collected during the aquifer test and the increases in water levels as a result of precipitation in all aquifers towards the end to the aquifer test established that the lower confined aquifer is hydraulically connected to the overlying aquifers.

This study demonstrates that long term monitoring of water levels, precipitation and barometric pressure can provide valuable information on the interrelationship of aquifers.
