Distribution, Sources and Fate of Atrazine in a Sandy-Till Aquifer
A field study was initiated around an atrazine-contaminated private dairy-farm well to investigate sources and extent of contamination from atrazine and its metabolites in the shallow glacia...
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.
Ecological Limits of Hydrologic Alteration in Wisconsin Streams
Groundwater withdrawal can significantly affect the flow regime of streams and rivers, but it is difficult to predict how hydrologic changes affect stream biological communities.
