In the 1940's the need to develop considerable water supplies led to the realization that little was known about the state of Delaware's ground-waters resources. The Chief of the USGS office in Salisbury, Maryland, William C. Rasmussen, encouraged State offficials to create a geological survey. Huber Denn of the Delaware Chamber of Commerce, George Simpson of the Farm Bureau, and the School of Agriculture of the University of Delaware's George M. Worrilow acknowledged and supported the creation of Geological Survey and its importance. Governor Elbert N. Carvel promoted legislation, with regard to water resources, with Seante Bill 129 which created the Delaware Geological Survey, introduced by State Senator William O. Cubbage in the 116 General Assembly and signed into law by Governor Carvel on June 4, 1951.
