Groundwater Quality

In Wisconsin, 70% of residents and 97% of communities rely on groundwater as their drinking water source. Wisconsin has a large amount of high-quality groundwater, but once this resource is contaminated, it becomes expensive and often nearly impossible to remove those contaminants. Because of this, we need to protect our groundwater from contamination. In order to do this effectively, we need to be aware of what areas are the most susceptible to groundwater contamination, and the factors that influence that susceptibility.

• Dunn County Groundwater Contamination Susceptibility
• County Groundwater Map

Many factors determine how susceptible any given location is to groundwater contamination- most of which are beyond our control. The most influential of these factors are:

• Soils
• Bedrock Type and Depth
• Location in the Landscape

There are however, two factors that we do have some level of control over, and those are Well Construction and Land Use
