A long-running Illinois science institution, this survey turns the state's hidden geology into practical knowledge for public safety, environmental planning, and economic development. Its work ranges from geologic mapping and drilling records to research that helps people understand land, water, minerals, and natural hazards.

Founded in 1851 and continuously operating since 1905, the Illinois State Geological Survey is one of Illinois's core public science organizations. It is part of the Prairie Research Institute at the University of Illinois Urbana-Champaign and serves the state with earth science research and information designed to support environmental quality, economic vitality, and public safety.
Its scientists and technical staff study Illinois geology in both basic and applied ways. The survey compiles geologic maps, gathers and manages statewide geologic data, and shares information about mineral resources, groundwater, drilling records, and geologic hazards with government agencies, industry, communities, and the public.
The survey is also a major keeper of the state's geologic memory. It maintains Illinois's official repository for drilling records, with more than 500,000 records for oil and gas wells, water wells, engineering borings, and other test holes. Alongside research, publications, field guides, and public outreach, that makes it an important source for anyone trying to understand how Illinois works below the surface.
