Depth-to-bedrock mapping of Grant County provides baseline information on unconsolidated surficial sediment thickness across the county. Bedrock aquifers in Grant County are susceptible to contamination from various land use activities, and depth to bedrock represents one of several factors affecting aquifer susceptibility. The results of this study...

The depth-to-bedrock raster of Lafayette County is a continuous model of surficial sediment thickness with a cell size resolution of 32.8 ft (10 m). Results show that the depth to bedrock in Lafayette County varies depending on physiographic setting. The largest values occur in the Pecatonica River valley, where more than 100 ft (30.5 m) of unconsolidated...

Silurian-aged bedrock in eastern Wisconsin is shallow, fractured, and contains groundwater that is susceptible to surface water contamination. Revisions to Wisconsin state rules ATCP50 and NR151 to regulate manure spreading over this Silurian-aged bedrock create the need for a depth-to-bedrock map of eastern WI. The Wisconsin Geological and Natural...

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...

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...
