Mineral Transformation and Release of Arsenic to Solution Under the Oxidizing Conditions of Well Disinfection
Guidance for disinfection of domestic wells in arsenic-sensitive areas of Wisconsin calls for a treatment at 20 percent of the chlorine strength and 10 percent of the contact time recommended for non-arsenic impacted wells.
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.
