Field evaluation of near source transport of contaminants in heterogeneous media
This project extended the investigation "Near Source Transport of Contaminants in Heterogeneous Media" of contaminant plume and groundwater mounding behavior by applying this work to a field...
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...
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.
Assessing Seasonal Variations in Recharge and Water Quality in the Silurian Aquifer in Areas with Thicker Soil Cover
The fractured Silurian dolomite aquifer is an important, but vulnerable, source of drinking water in northeast Wisconsin (Sherrill, 1978; Bradbury and Muldoon, 1992).
