Groundwater

Approximately two thirds of the people living in Wisconsin get their drinking water from groundwater. Adequate supplies of uncontaminated groundwater are crucial not only to the health of those families but also for the continued growth of agricultural production and cutting-edge industries in Wisconsin. We are continually confronted with new challenges in securing water of sufficient quality and quantity. Join us in working to protect and preserve the purity and quantity of Wisconsin's groundwater resources for today and future generations.

Pure, healthy groundwater is vital to our present, past and future economies.
