At the WGNHS, we carry out applied projects with specific and very practical goals, but most projects also contain a research component. Topics of general interest to me include groundwater quality in urban areas, water quality at municipal water systems, geologic and geochemical factors affecting trace metals in Wisconsin’s groundwater, and flow and contaminant transport across aquitards. Another area of interest is water table response to climate extremes. The WGNHS maintains, along with the USGS, a state-wide groundwater level monitoring network. You can explore these data here: http://wi.water.usgs.gov/data/groundwater.html
Part of the mission of the WGNHS is to collect, interpret, disseminate, and archive natural resource information. To help fulfill this part of our mission, I’ve worked to improve the ways in which we provide information to the public. Our GIS staff recently developed a web-based mapping application, the Hydro Data Viewer, to provide geologic and hydrogeologic data sets in an easy-to-use and broadly available format. The Viewer is currently used by the Wisconsin Department of Natural Resources, and we hope to have it on our web site soon.
My current projects include the fate and transport of artificial sweeteners and other novel wastewater tracers in groundwater, geologic sources of radium to public water supply wells, and redox conditions in heavily pumped groundwater systems. I participate in a project examining the hydrologic impacts of industrial sand mining in Wisconsin.
