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 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.
