Risk from pathogens and exposure to antibiotic resistance genes in private wells in southwest WI
Private wells supply water for rural residents of southwest Wisconsin, where fractured rock aquifers are vulnerable to contamination from septic systems and agriculture. Our recent research ...
An experimental investigation on the leaching of per- and polyfluoroalkyl substances (PFAS) from contaminated soil
For per- and polyfluoroalkyl substances (PFAS) released into the natural environment, soil represents a major pathway for their transport to the underlying groundwater, which represents a ma...
Long-term threat of geogenic contaminants to water quality and quantity in the Midwestern Cambrian Ordovician Aquifer System
Regulatory and research efforts often focus on prevention and/or remediation of anthropogenic contaminants in groundwater; however, naturally occurring (geogenic) contaminants (e.g., U, Ra, ...
Biomanipulation of Groundwater Flooding
Changes in land-use/land management and climate perturb the balance of hydrologic fluxes in catchments around the world. In extremely flat, internally or poorly-drained landscapes, imbalance...
Aligning the Wisconsin Idea on water: Interpreting public perspectives and values
Rural land covers most of the state of Wisconsin and thus overlies the majority of aquifer volumes in the state. Rural landowners and land workers are thus intimately connected to the quanti...
Assessment of biochar application to reduce nitrate leaching through agricultural vegetative treatment areas
Nitrate (NO3-) is the most prominent contaminate of private wells in Wisconsin, and agricultural has been directly linked to contributing to NO3- contamination in rural areas. There are mult...
Measurement of bacterial transport and immobilization in variably saturated geologic materials of WI
The occurrence of bacteria and other microbial agents in private wells across the state of Wisconsin poses significant risks to human health. Discrepancies between bacteria measurements in d...
