Verification and Characterization of a Fracture Network Within the Maquoketa Shale Confining Unit, Southeastern Wisconsin
The Maquoketa Formation, a dolomitic shale, forms the most important aquitard in eastern Wisconsin, USA, isolating the water-table and Silurian aquifers from the underlying Cambrian-Ordovician aquifer.
Mechanical Controls on Fracture Development in Carbonate Aquifers: Implications for Groundwater Flow Systems
Carbonate aquifers form important regional sources of drinking water in eastern and southern Wisconsin. Previous work in Door County suggests that vertical fractures as well as horizontal partings and dissolution zones provide the primary pathways for groundwater flow
Health Effects of Arsenic-Contaminated Drinking Water
Inorganic arsenic is a well-known human poison that causes a wide array of adverse health effects. The World Health Organization and U.S. Environmental Protection Agency classify inorganic arsenic as a human carcinogen.
Analysis of Microbiological and Geochemical Processes Controlling Biodegradation of Aromatic Hydrocarbons in Anaerobic Aquifers
Benzene, toluene, ethylbenzene and xylenes (BTEX) are among the groundwater contaminants of greatest concern because of their toxicity, their solubility in water, and their resistance to degradation in anaerobic environments.
A Study of Fecal Indicators and Other Factors Impacting Water Quality in Private Wells in Door County, Wisconsin
The primary goal of this study was to obtain the percentage of wells impacted by contaminants based on three indicators studied by the Environmental Protection Agency (EPA) as tools to identify fecal contamination in groundwater.
Viral Contamination of Household Wells Near Disposal Sites for Human Excreta
Recent studies monitoring ground water for enteric viruses have focused on municipal wells, whereas the incidence of viruses in private household wells is unknown.
