Jo Daviess County IL Karst Feature Database

<DIV STYLE="text-align:Left;"><DIV><P><SPAN STYLE="font-weight:bold;">Please see the individual layer/table below to access the detailed metadata.</SPAN></P><P><SPAN>In order to support science-based water resource management, a systematic effort was undertaken to characterize the nature and function of the hydrogeology in Jo Daviess County, Illinois. Jo Daviess County is a karst area. Karst is a geologically and hydrologically integrated or interconnected and self-organizing network of landforms and subsurface large-scale, secondary porosity created by a combination of fractured carbonate bedrock, the movement of water into and through the rock body as part of the hydrologic cycle, and physical and chemical weathering (Panno, S.V. et al, 2017). Springs, cover-collapse sinkholes, crevices, and caves are among the defining features of a karst terrain; each of these features is found in Jo Daviess County. Examples of these features have been located in the field and using other remotely-sensed data and characterized by scientists from the Illinois State Geological and Water Surveys (Prairie Research Institute, University of Illinois at Urbana-Champaign). For this project, groundwater samples were collected from springs and wells and analyzed for inorganic chemistry, dissolved organic carbon, stable isotopes of water, and tritium. The project objective was to initiate a karst feature database, to collect water samples from springs to determine groundwater background concentrations of major anions, cations, and field parameters, and to then characterize and group the different populations of groundwater within Jo Daviess County. This project was supported by Grant Awards F16AP00772 and F18AC00961, from the U.S. Fish and Wildlife Service to the League of Women Voters of Illinois Education Fund as well as support from the Prairie Research Institute, University of Illinois.</SPAN></P><P><SPAN>In addition to reports created for each sampling location (containing data, photographs and interpretation) and submitted to USFWS as grantee performance reports for Grant Award F16AP00772, the publication cited below references the data and provides interpretation:</SPAN></P><P><SPAN>Panno, S.V., W.R.
