In the Late Pleistocene, continental glaciers covered the area, and when they retreated they left behind a unique landscape. On the western side of the county the Silurian escarpment forms high cliffs along the Green Bay shoreline; only a few miles to the east the land meets Lake Michigan with sandy beaches and diverse wetlands.

Most annual recharge occurs over a few weeks following spring rains and snowmelt; during this period groundwater levels often rise by tens of meters. Thermal and geochemical data collected during specific recharge events show that recharge water can move from the land surface to tens of meters below the water table in a matter of hours or days.

In this environment, closing the water budget - balancing recharge processes with discharge processes - is extremely challenging, yet understanding recharge and discharge processes is essential for solving local groundwater contamination problems and for making wise land-use management decisions for the area.
