Ultrasonic verification technique for evaluating well seals
An ultrasonic nondestructive testing technique has been developed to assess the integrity of well seals. The pulse-echo inspection technique was used to evaluate the quality of the bond betw...
Impact of tunnel dewatering on surface water bodies in Mil. County
The interaction of Milwaukee County's Northshore Tunnel with surface water bodies was analyzed. Seepage meter measurements established that the tunnel induced recharge into the dolomite and...
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.
Hydrostratigraphic and Groundwater Flow Model: Troy Valley Glacial Aquifer, Southeastern Wisconsin
Groundwater is an important resource in Wisconsin, especially in areas of southeastern Wisconsin outside the surface water divide of the Great Lakes that are prohibited from using water from Lake Michigan by the Great Lakes Compact.
