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... -
