In situ removal of iron, manganese, and radium from groundwater
This project was undertaken to determine if radium coprecipitates with iron and manganese during in situ oxidation of ground water and whether there are locations in Wisconsin where the coin...
Renovation of pesticide contaminated rinse waters
Many instances of severe contamination of groundwater by pesticides have been traced to spills at pesticide mixing/loading sites. Under Wisconsin law, farmers and commercial applicators han...
Describing Connected Fracture Flow with Pressure Waves – Oscillating Flow Interference Testing
The state of Wisconsin is blessed with abundant groundwater resources resulting from the thick, high-porosity and high-permeability sedimentary aquifers that underlie the state, as well as the humid climate it experiences.
Using the New Rome Formation as a Geologic Weighing Lysimeter for Water Management in Wisconsin’s Sand Plain
This project tested the concept of using geologic weighing lysimeters (GWLs) to estimate components of the water balance in parts of Wisconsin’s central sand plain where the New Rome Formation (NRF), a regional aquitard, occurs.
Subsurface Fate and Transport of Cryptosporidium in Soils of Wisconsin’s Carbonate Aquifer Region
Cryptosporidium parvum is a waterborne pathogen that has been demonstrated to have a significant reservoir in cattle manure. As agriculture in Wisconsin is famous for its dairy industry, there are approximately 1.3 million dairy cows in Wisconsin in addition to about 250,000 beef cattle.
Groundwater Pumping Effects on Groundwater Levels, Lake Levels, and Streamflows in the Wisconsin Central Sands
The study summarized here examined the impacts of groundwater pumping on Wisconsin Central Sands water resources. Prominent hydrologic studies in the 1960s and 1970s warned that the growth in groundwater pumping for agricultural irrigation in the region
