The Illinois State Water Survey (ISWS) is a Division of the Institute for Natural Resources Sustainability (INRS)  of the University of Illinois at Urbana-Champaign (UIUC).  The Water Survey has flourished for more than a century by anticipating and responding to new challenges and opportunities to serve the citizens of Illinois. Today, the ISWS continues to demonstrate flexibility and adaptability by developing new programs, while continuing to provide long-standing services upon which Illinoisans have come to rely.

The long and distinguished history of the Water Survey took a new turn in July 2008 when the ISWS and the other Scientific Surveys were transferred to the UIUC as the INRS.  This, along with staff changes and facilities additions, have brought a new sense of dynamism. Overall, we are positioning ourselves to more effectively achieve our mission through a broader collaboration with UIUC faculty and organizations.

The organizational structure of the Water Survey includes four centers (Center for Atmospheric Science, Center for Chemistry & Technology, Center for Groundwater Science, and Center for Watershed Science), and one national program (National Atmospheric Deposition Program), together with central administration and management functions conducted in the Office of the Director. In addition to its traditional strengths, the Water Survey is enhancing its monitoring, analytical, and mathematical modeling capabilities to address issues with greater efficiency and productivity.

The Scientific Surveys of the University of Illinois at Urbana-Champaign are the primary agencies in Illinois responsible for producing and disseminating scientific and technological information, services, and products related to the environment, economic development, and quality of life. To achieve this mission the Scientific Surveys conduct state-of-the-art research and collect, analyze, archive, and disseminate high-quality, objective data and technical information. The information, services, and products provide a sound technical basis for the citizens and policymakers of Illinois and the nation to make wise social, economic, and environmental decisions.
