Reliable water-level measurements are essential for understanding groundwater flow systems and recharge/discharge processes and for managing Wisconsin groundwater resources.

Human gastrointestinal viruses are known to contaminate municipal drinking water wells. In one peer-reviewed study, 141 of 448 groundwater sites (31.5%) in 35 states were positive for viruses.

Understanding the spatial distribution of groundwater recharge is a basic prerequisite for effective groundwater resource management and modeling.

The State of Wisconsin requires aqueous environmental samples at solid waste landfills to be tested for chemical oxidation demand (COD).

This project involved geologic and hydrogeologic approaches to investigate the release of naturally occurring arsenic concentrations to well water in a confined sandstone aquifer in northeastern Wisconsin.

Production of sweet corn for processing in the Midwest is concentrated in Wisconsin, Minnesota, and Illinois with these three states accounting for over 60% of the 1991 national production of about 3.3 million tons.
