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...

The City of Waupaca, Wisconsin, uses groundwater pumped from a network of seven high-capacity wells as its municipal water supply. Recent increases in the concentration of nitrate in the municipal water supply raised questions about the source of this contamination and whether it might eventually exceed standards for drinking water. This study combines...

The WGNHS and the U.S. Geological Survey characterized the hydrogeology and developed a groundwater flow model to assess groundwater resources in Columbia County. This report describes regionally extensive aquifers and presents several extensive datasets collected from deep wells across the county. The report also documents the construction and...

The Quaternary geology of Fond du Lac County consists of glacial deposits and landforms dating to the last part of the Wisconsin Glaciation (ca. 20,000 to 12,000 yr BP) and nonglacial deposits and landforms of Holocene age (11,700 yr BP to present). Glacial till and meltwater sediment were deposited by the Green Bay and Lake Michigan Lobes of the...

Cold-water trout habitat in Wisconsin is projected to substantially decrease as a result of climate change. The extent of habitat loss depends, in part, on groundwater discharge to streams, which can provide cool-water refuges for trout. Survey hydrogeologists used field measurements and models of groundwater flow and stream temperature to evaluate how...

Dodge County lies in southeast Wisconsin, an area almost entirely covered by glacial deposits. This map interprets the distribution of the buried bedrock units across the county. Geologist Esther Stewart’s refinement of the bedrock elevation contours may help land-use planners identify areas most susceptible to groundwater contamination from applications...

Door County, the narrow peninsula in eastern Wisconsin, is home to numerous wetlands, many of which are fed by groundwater. Poor-quality groundwater discharging to a wetland can alter the ecology of the wetland and harm native plant and animal communities. This report documents a one-year study of six wetlands. Researchers recorded water quality and...

Report, database, field protocol, photos, and site sketches documenting the multi-year project inventorying springs in Wisconsin with discharge rates of at least 0.25 cubic feet per second.

Analysis of the groundwater resources in Bayfield County, Wisconsin. Includes report, five plates, and digital data.

Results of regional study characterizing the elemental composition of rocks found at the Wonewoc-Tunnel City contact interval in west-central and southwest Wisconsin.

This report documents the groundwater flow model that was developed for western Chippewa County, Wisconsin. It also presents analyses that were run to evaluate how industrial sand (frac sand) mining and irrigated agriculture--might affect the water table and base flows of nearby headwater streams.

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.

The bulletin describes the state-of-the-art scientific tool that can be used to help make good decisions about high-capacity well placement and pumping, as well as land use in Wisconsin's Central Sands region. It can also be used to predict which wells and well locations would have the greatest impact on nearby lakes and streams. The user's manual...

Test hole drilled to 1,000 feet on Fort McCoy property provides data for understanding the geothermal gradient in Wisconsin and the hydrogeologic conditions found at Fort McCoy.

Details the current WGNHS approach to pXRF analysis, including usage guidelines, sample preparation, calibration, and plotting techniques.

The 2016 groundwater flow model is a three-dimensional model using state-of-the-art representation of the hydrogeology of Dane County. This report describes the model, appendices provide data, and the user's manual provides basic instructions and recommendations for running the model.
