The Delaware Geological Survey (DGS) was first established by the General Assembly in 1837. It was reestablished by that body in 1951 and is a senior natural resources unit in Delaware. The Delaware Geological Survey's mission is, by statute, geologic and hydrologic research and exploration, and dissemination of information through publication and public service.
