Role of mobile colloids in the transport of chemical contaminants in groundwater
Mobile colloids in groundwater enhance the transport of chemicals which sorb to particle surfaces. This study addressed the potential for colloid-mediated transport in Wisconsin aquifers by ...
Integrated decision support for wellhead protection
This report describes a Geographic Information System application named WELLHEAD. It integrates geographic data on highways, townships and hydrography on flowing and standing water and wetl...
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.
Drawdown in the Northeast Groundwater Management Area (Brown, Outagamie, and Calumet Counties, WI)
In Eastern Wisconsin, water levels over large regions have decreased due to many wells pumping from beneath a confining layer. This combination of geology and cumulative pumping from the wells has resulted in a large regional drawdown cone centered around Brown County, Wisconsin.
