Depth to Silurian Bedrock in Eastern Wisconsin
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...-
