Septic & well water services in Winona County, MN

Sheer Mississippi River bluffs and the deeply eroded Whitewater valley define this Driftless county, with thin loess over St. Peter Sandstone and Prairie du Chien dolomite on the ridgetops. Slope, shallow bedrock, sinkholes on the Lewiston and Altura uplands, and springs feeding trout streams make bedrock separation and setbacks the dominant siting rules. Wells reach the Jordan or deeper Cambrian sandstones at 150 to 450 feet, with nitrate and bacteria the usual concerns.
