A Study of the Factors Affecting the Gross Alpha Measurement and a Radiochemical Analysis of Some Groundwater Samples from the State of Wisconsin Exhibiting an Elevated Gross Alpha Activity
Ninety eight groundwater samples from water utilities from around the state of Wisconsin were analyzed for uranium activity (U-234, U-235, and U-238), thorium activity (Th-228, Th-230, Th-232), radium activity (Ra-226 and Ra-228), polonium-210 activity (Po-210)
Precambrian Basement Topography Using 3D Modeling of Gravity and Aeromagnetic Data in Southeastern Wisconsin and Fond Du Lac County
Increased concerns about groundwater resources in Wisconsin have brought about the need for better understanding of the subsurface geologic structure that lead to developing conceptual hydrogeologic models for numerical simulation of groundwater flow.
