Inventory and Analysis of Flowing Artesian Wells in Bayfield County, Wisconsin
This report presents a county-wide inventory of flowing artesian wells in Bayfield County. Flowing artesian wells are a remarkable resource of high-quality water that both community members and tourists value. This report provides baseline water quality data that are a valuable resource for future assessments. Data collection occurred in 2022. Includes... -
Geologic Carbon Sequestration: Assessment of Mid-Continent Rift Core Porosities and Permeabilities in Wisconsin
This report presents results from a study investigating the potential for carbon dioxide sequestration in the ancient Keweenawan sedimentary formations in northern Wisconsin. Bedrock drill core from the Copper Harbor and Nonesuch formations were examined for their properties to store carbon dioxide (Copper Harbor) and seal that carbon dioxide (Nonesuch).... -
Geologic Map of the Fennimore and Mount Hope 7.5-Minute Quadrangles, Grant County, Wisconsin
The geologic map of the Fennimore and Mount Hope quadrangles includes 1:24,000-scale mapping of both surficial and bedrock geology. The mapping was initiated to support groundwater studies in the area. The map and accompanying report present the Paleozoic bedrock stratigraphy, including structures, as well as data from three new bedrock drill cores...-

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...-

Elemental Chemostratigraphy of the Cottage Grove Hole MP-18 Core: Implications for Litho- and Hydrostratigraphy in Southcentral Wisconsin
Part of a larger regional study of the Eau Claire Formation, the core, from Dane County, Wisconsin, was tested using a portable x-ray fluorescence (pXRF) elemental analyzer. The report presents the data set and discusses lithologic interpretations, subsurface lithostratigraphic correlations, and hydrostratigraphic frameworks. Includes photos of the core. -
