Book Description
This book discusses the karst and pseudokarst of the Upper Midwest, USA, consisting of the states of Minnesota, Wisconsin, Iowa, and Illinois—the first regional synthesis in 40 years. Starting with an overview of the regional geology of what is largely glaciated fluviokarst and paleokarst developed on Paleozoic carbonates, but including other lithologies such as the St. Peter Sandstone and the Ft. Dodge Gypsum, the caves, springs, sinkholes, and karst hydrogeology of each state are described. Special attention is devoted to the region’s longest caves: Coldwater Cave, Mystery Cave, and the Minnesota Cave Preserve caves. Application of tools such as data loggers and LiDAR, with new conceptual models such as hypogenic speleogenesis, has been transformative here. Special topics include lead and zinc mining in the Driftless Area, vertebrate and invertebrate cave fauna near the Laurentide ice limit, the impact and policies of nutrient and herbicide intensive modern agriculture on karst, and paleoclimate studies. The discovery, exploration, institutional history of caving organizations, and show caves of the Upper Midwest, from the year 1700 onwards, are brought up to date. The top 10 historical paradigms of cave and karst science in the Midwest are reviewed. Perspectives on paleontology, archeology, and Native American rock art are included.

Book Description
During an 8 month sampling campaign, 22 wells (11 private, 8 municipal, and 3 monitoring wells) completed in the fractured Silurian dolostone aquifers of southern Wellington County, Ontario, Canada were sampled for enteric viruses, fecal bacteria, artificial sweeteners, pharmaceuticals, and other common constituents of human and animal sewage. The vulnerability of fractured bedrock aquifers to sewage-derived contaminants was highlighted when 91% of the sampling wells exhibited at least one of the 49 sewage derived contaminants analyzed in this investigation. Low concentrations of viruses were found in 45% of the wells but each of these wells only exhibited viruses on one of the monthly sampling events. Current regulations in Canada and the United States require the monitoring of total coliforms and E. coli to determine the presence of a sewage influence in drinking water supplies, but statistical calculations of positive and negative predictive values, specificity, and sensitivity showed that the artificial sweetener acesulfame may act as a more effective tracer of sewage-derived contamination and the combination of ibuprofen and total coliforms may be able to indicate up to 70% of virus occurrences in southern Wellington County's fractured bedrock aquifers. While the results may suggest that private well owners consuming untreated groundwater are at risk of acute gastrointestinal illness, the scope of the current study does not permit an assessment with regards to the risk of consuming water from municipal supplies.
