Delaware Geological Survey

The Delaware Geological Survey (DGS) is a scientific agency for the State of Delaware, located at the University of Delaware (UD) which conducts geologic and hydrologic research, service, and exploration. The mission of the DGS is to provide objective earth science information, advice, and service to citizens, policymakers, industries, and educational institutions of Delaware. The DGS became formally affiliated with the university's College of Earth, Ocean, and Environment (CEOE) in July 2008. Most DGS scientists have secondary faculty appointments in the College's Department of Geological Sciences.

The DGS is one of the 50 state geological surveys in the United States. By statute, the DGS is the state agency responsible for entering into agreements with its counterpart federal agencies, including the U.S. Geological Survey (USGS), the USGS Office of Minerals Information (formerly the U.S. Bureau of Mines), and the Bureau of Ocean Energy Management, Regulation and Enforcement (formerly the U.S. Minerals Management Service), and for administering all cooperative programs of the state with these agencies.
