Local Karst Geology and Drinking Water

June 11, 2011

How does our local karst geology affect the quality of our drinking water? On Saturday, June 11, a free presentation will be held at the public library in Soldiers Grove, located at 102 Passive Sun Dr., from 10:00 to 12:00. A field trip will be offered at 12:30 to view local karst features.

Karst refers to our cracked limestone and dolomite bedrock that is capable of quickly transporting surface water, and hence pollutants, into our drinking water. Learn about where our groundwater comes from and how it is recharged. Find out how local land uses can affect what comes out of your tap.

The presentation will be given by geology professor Kelvin Rodolfo of rural Viroqua, followed by a Q and A from the audience. He will also explain the Wisconsin Geological Survey's Interagency Karst Reporting Form that landowners can complete and submit for verification of karst features.

Attendees are encouraged to bring a bag lunch and stay for the field trip at 12:30. Southwestern Wisconsin is underlain with karst geology, and some of the most emblematic features of this rock formation are sinkholes, shallow soils, and springs.

The Soldiers Grove Public Library and the Crawford Stewardship Project are co-sponsoring the event as part of a regional effort to help residents learn about and identify karst features where they live. The karst presentation is free and open to all. For more information, call 735-4277.

The monitoring, supervision, clean-up, restitution, fines are not happening, thus the true cost of CAFOs never find the way onto the balance books." Talking point from the CAFO Conference.
