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 t...
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 Formati...
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, the...
Assessing Seasonal Variations in Recharge and Water Quality in the Silurian Aquifer in Areas with Thicker Soil Cover
The goal of this project was to gain an understanding of seasonal variations in recharge, the timing of recharge events, and the resulting water-quality variations in the Silurian dolomite a...
