Fate of groundwater phosphorus from septic systems near lakes
As lakes become increasingly surrounded by conventional septic systems, it is important to be able to communicate the extent to which these systems will impact a lake’s long-term biological
Investigating sources of salinity associated with Ra and Sr in the Cambrian-Ordovician aquifer system of eastern WI
The Midwestern Cambrian-Ordovician aquifer system, an important drinking water source, contains elevated levels of radium (Ra) and strontium (Sr) in many Wisconsin municipalities. Radium is ...
Correlating bedrock folds and fractures to arsenic detection in drinking water, southeast Wisconsin
Arsenic release mechanisms into groundwater wells and bedrock sources of arsenic have been well studied in Outagamie and Winnebago counties in northeastern Wisconsin. A thorough understandin...
Source to sink evaluation of phosphorus in the hydrologic system in Wisconsin: Implications for lake eutrophication
Phosphorus loading in Wisconsin is responsible for significant lake eutrophication throughout the state, with severe societal and economic impacts, including a loss of recreational tourism, ...
Valuing groundwater quality: A cost function analysis of Wisconsin water utilities
With growing concerns about groundwater contamination and its effects on drinking water supply, it is becoming increasingly important to understand the costs and benefits of protecting groun...
Investigating in-season cover crops for reducing nitrate loss to groundwater below potatoes
In agricultural production, nitrogen fertilizers and other nutrient sources (e.g., manure, bio-solids, and legume credits) are valued for their ability to increase crop yields. However, some...
Impact of changing snow cover and frozen ground regimes on groundwater recharge
Understanding the multifaceted feedbacks between snow cover, frozen ground, infiltration and GW recharge are critical for predicting the ways in which our groundwater resources will be affec...
Microbially-mediated oxidation of trace element-bearing sulfide minerals in sandstones of Trempealeau County, WI
This is an experimental project designed to gain insight into the kinetics of biologically-mediated sulfide mineral (e.g. pyrite) oxidation in sandstone aquifer sediments from Trempealeau Co...
