The southwest Wisconsin groundwater and geology study (SWIGG) was a cooperative effort between Grant, Iowa, and Lafayette county governments, with scientists from the U.S. Geological Survey, U.S. Department of Agriculture, Marshfield Clinic Research Institute, and WGNHS. Researchers tested water quality in hundreds of private water wells across the three...

The Central Sands nitrate and neonicotinoid database consists of over 100,000 measurements of nitrate and neonicotinoid concentrations in groundwater from wells across Adams, Juneau, Marquette, Portage, Waushara, and Wood counties collected between 1953 and 2021. These counties comprise the Central Sands Groundwater County Collaborative (GSGCC), which...

The portable X-Ray Fluorescence (pXRF) instrument provides fast, real-time, non-destructive, multi-element geochemical data (i.e. elemental concentrations) on rocks and minerals at a relatively low cost and with minimal sample preparation. This study quantifies the precision and accuracy of measurements collected by the WGNHS pXRF on reference materials...

Elevation contour data and an accompanying report provide an updated interpretation of the elevation of the top of Precambrian bedrock in south-central Wisconsin. The elevation surface was developed from geologic and geophysical data, and provides new detail on the entrenched bedrock valleys that were incised into the north and south ranges of the Baraboo...

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 geologic map of the Bloomington and Brodtville quadrangles includes 1:24,000 scale mapping of both surficial and bedrock geology. There is little structural folding or faulting in this portion of the Driftless Area. Thus, it is ideal for studying the hydrostratigraphic framework of the mapped units. The accompanying report presents stratigraphic...

The Quaternary geologic map of Jefferson County, Wisconsin, provides details about the surficial sediment and landscapes that were formed largely in the footprint of the Laurentide Ice Sheet's southern Green Bay Lobe during the late Wisconsin Glaciation (ca. 20,000 years before present). These landscapes include lowlands underlain by glacial and...

This report documents work completed as part of a grant from the U.S. Geological Survey’s National Groundwater Monitoring Network (NGWMN) program. It provides an overview of the Wisconsin Groundwater-Level Monitoring Network (WGLMN) and provides detailed description of well evaluation and repair activities, and drilling of new monitoring wells across the...

The geologic map of the Castle Rock and Long Hollow quadrangles includes 1:24,000 scale mapping of both surficial and bedrock geology. The accompanying report presents new observations about bedrock folds and fracture sets in this portion of the Driftless Area that lies just north of the main Upper Mississippi Valley zinc-lead mineral district. The...
