Hydrogeology of the sandy uplands of the Bayfield Peninsula, Wisconsin
The sandy uplands of the Bayfield Peninsula are primary contributors to regional groundwater recharge and provide baseflow to streams in the area. Few data exist, however, to characterize upland hydrogeology or its susceptibility to groundwater contamination. Here, data from two new cores and wells, one existing well, and a lake in the sandy uplands...-

Applications of the Columbia County, Wisconsin, Groundwater-Flow Model
Computerized groundwater-flow models provide scientific analysis of water resources. Since its initial development in 2014, the Columbia County groundwater-flow model has been used to respond to requests for information about specific groundwater and land use issues. This companion report to the Hydrogeology and simulation of groundwater flow in Columbia... -
Assessing Groundwater Quality in Kewaunee County, Wisconsin, and Characterizing the Timing and Variability of Enteric Pathogen Contamination within the Dolomite Aquifer in Northeastern Wisconsin
Documentation of two studies looking at the Silurian dolomite aquifer in northeastern Wisconsin. Researchers quantified the extent of contamination from coliform bacteria, E. coli, and nitrate in Kewaunee County’s private wells. They also examined how wastewater from septic systems and livestock manure interact with environmental conditions and geology... -
