Southwest Wisconsin Groundwater and Geology (SWIGG) study

The fractured bedrock aquifers of southwest Wisconsin are often overlain by shallow soils, so private wells are potentially vulnerable to contamination by nitrate and pathogens from the land surface.  The goal of this study is to evaluate the extent and causes of private well water contamination in three southwest Wisconsin counties.

Water Quality Across Regional Stream Networks: The Influence of Land Cover and Land Use, Climate, and Biogeochemical Processing on Spatiotemporal Variance

Land cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. As LC/LU and climate continue to change we can expect changes in water quality. This project seeks to understand the drivers of spatial and temporal variability in water quality across scales using new and existing data to...
