  • Jo Daviess County collaboration tackles water quality

    With its unique geology marked by sinkholes, crevices, and caves, Jo Daviess County is highly susceptible to water contamination. Scientists from the Illinois State Geological Survey (ISGS) and Illinois State Water Survey (ISWS) are using their expertise and collaborating with a local organization to help citizens understand water quality issues and protect their water supplies.

  • Initial results show Mt. Simon Sandstone in Macon County is suited to carbon storage

    Preliminary results from a stratigraphic characterization well drilled in December 2018 by the Illinois State Geological Survey (ISGS) and collaborators near Mt. Auburn, Illinois, indicate that the Mt. Simon Sandstone at this location has excellent reservoir characteristics for storage of CO2. The T. R. McMillen #2 well is part of the CarbonSAFE Illinois–Macon County project, which is intended to establish the feasibility of storage of 50 million tonnes or more of CO2.

  • Mahomet Aquifer Protection Task Force issues recommendations

    A task force formed by the Illinois General Assembly to identify gaps in protection of the Mahomet Aquifer has issued its final recommendations. Illinois State Water Survey hydrologist George Roadcap served as a member of the task force, and other Prairie Research Institute scientists provided data and expertise to support the group’s yearlong effort.

  • ISGS, ISWS install new wells for national groundwater monitoring

    Scientists and staff from the Illinois State Geological Survey and the Illinois State Water Survey  ollaborated with county and local governments in Kane County to install groundwater-monitoring wells in northeast Illinois as part of the U.S. Geological Survey’s National Ground Water Monitoring Network

  • 2018 Celebration of Excellence

    On April 11, the Prairie Research Institute honored employees for their outstanding achievements and excellent work. Selection committees composed of staff from across the organization reviewed multiple strong nominations before selecting the 2018 honorees.

  • PRI researchers gain new insights into how groundwater flows within the Illinois Basin

    A conceptual model of water movement in rock layers many feet underground, published by Prairie Research Institute scientists, shows for the first time that water is flowing steadily south through the thick sequence of rock layers that form the Illinois Basin.
