Passage of Microorganisms in Septic Tank Effluents Through Mound Sand in a Controlled Laboratory Environment
Pristine groundwater is a greatly treasured Wisconsin resource. Protection of this resource in part relies on removal of organisms from anthropogenic activities that are likely to contaminate ground water.
Improvement of Wisconsin Groundwater Monitoring Network
Reliable water-level measurements are essential for understanding groundwater flow systems and recharge/discharge processes and for managing Wisconsin groundwater resources.
Susceptibility of La Crosse Municipal Wells to Enteric Virus Contamination From Surface Water Contributions
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.
Refinement of Two Methods for Estimation of Groundwater Recharge Rates
Understanding the spatial distribution of groundwater recharge is a basic prerequisite for effective groundwater resource management and modeling.
Evaluating Options for Changing Groundwater Monitoring Requirements for Landfills to Reduce Mercury Used by Laboratories
The State of Wisconsin requires aqueous environmental samples at solid waste landfills to be tested for chemical oxidation demand (COD).
Geologic and Geochemical Controls on Arsenic in Groundwater in Northeastern Wisconsin
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.
