“Hydrogeology of Karst in NE Wisconsin” Presented at Door County Fire Company

Whether it is known as the bluff or the ledge or the great arc, the Niagara Escarpment was created more than 430 million years ago. Today, Door County has built its economy on the visitors who come to see these dramatic rock formations and the vistas they provide. However, despite all the benefits, the escarpment and the thin soil of the cuesta contribute to a very problematic situation. The highly fractured karst landscape of the dolomite geology of Door County is prone to groundwater contamination.

Maureen Muldoon

During the presentation titled “Hydrogeology of Karst in NE Wisconsin: Why are Some Areas More Vulnerable to Contamination than Other Areas?,” two experts in the fields of geology and groundwater quality will explain this critical situation. The presentation takes place at the Door County Fire County in Sturgeon Bay on June 8 at 7 pm. Maureen Muldoon, PhD, of University of Wisconsin – Oshkosh, and Kevin Masarik, of UW-Stevens Point, will lead the presentation.

Muldoon is Professor of Hydrogeology and Environmental Geology at UW-Oshkosh and has done her doctoral thesis on the Hydrogeologic Characterization of the Silurian Dolomite in Door County. Her topic will give an overview of how the Silurian dolomite aquifer behaves and its relation to groundwater quality.

Masarik is a groundwater education specialist with UW-Extension in the College of Natural Resources at UW-Stevens Point. His extension teaching focuses on groundwater and drinking water quality education targeted toward populations served by rural residential well water systems. He will present recent test results of local well water testing.
