Amy Wiersma

As a Hydrogeologist, I conduct local- and county-scale groundwater studies in Wisconsin and assist local and state governments, industries, and the public in interpreting and using the information to make informed decisions about groundwater. I develop educational groundwater materials and participate in outreach to increase awareness of the Survey’s groundwater resources and ensure they are easily accessible to stakeholders.
