  • Rasmussen, W.C.; Haigler, E.B. (Newark, DE: Delaware Geological Survey, University of Delaware, 1953)
    This report discusses the occurrence of ground water in relation to certain problems in highway construction and maintenance. These problems are: the subdrainage of roads; quicksand; the arrest of soil creep in road cuts; ...
  • Groot, J.J.; Rasmussen, W.C.; Hulme, A.E. (Newark, DE: Delaware Geological Survey, University of Delaware, 1954-04)
    This report describes the geological and lithological conditions in the Newark area, and the occurrence, quantity, and quality of the available ground-water supply. Newark is located on the Fall Line, the boundary between ...
  • Organist, D.M.; Richards, H.G.; Groot, J.J. (Newark, DE: Delaware Geological Survey, University of Delaware, 1954-11)
    In the Coastal Plain of Delaware, the non-marine Cretaceous sands and clays are separated from the Tertiary formations by a series of marine formations of Upper Cretaceous age. The sedimentary and hydrologic characteristics ...
  • Marine, I.W.; Rasmussen, W.C. (Newark, DE: Delaware Geological Survey, University of Delaware, 1955-05)
    Delaware has an abundant supply of ground water of a quality suitable for most purposes. About 30 million gallons of water a day was pumped from the ground in 1954. It is estimated that this is roughly 1/16 of the optimum ...
  • Groot, J.J. (Newark, DE: Delaware Geological Survey, University of Delaware, 1955-07)
    The non-marine Cretaceous sediments of northern Delaware older than the Magothy formation cannot be divided accurately into formations or mappable geologic units because their lithologic characteristics are very similar. ...
  • DGS Staff (Newark, DE: Delaware Geological Survey, University of Delaware, 1956)
    This is a brief story about water and the ways in which the Delaware Geological Survey helps insure that you will always have a plentiful supply of this precious natural resource.
  • Rasmussen, W.C.; Groot, J.J.; Martin, R.O.R.; McCarren, E.F.; Behn, V.C. (Newark, DE: Delaware Geological Survey, University of Delaware, 1957-06)
    Northern Delaware, the area above the Chesapeake and Delaware Canal in New Castle County, is an area of rapidly growing population and expanding industry. In some places the demand for water has reached or exceeded the ...
  • Cohen, B. (Newark, DE: Delaware Geological Survey, University of Delaware, 1957-07)
    The purpose of this investigation was to obtain data on and study the factors affecting the salinity of the Delaware River from Philadelphia, Pennsylvania to Reedy Island, Delaware. The techniques of analyses of data and ...
  • Ward, R.F.; Groot, J.J. (Newark, DE: Delaware Geological Survey, University of Delaware, 1957-11)
    This investigation was undertaken to locate deposits of rock, sand, gravel, fill and borrow in northern New Castle County which may be potential sources of material for highway construction, and to prepare maps and ...
  • Rasmussen, W.C.; Groot, J.J.; Depman, A.J. (Newark, DE: Delaware Geological Survey, University of Delaware, 1958-06)
    A thick aquifer of Eocene age underlies the Dover area, Delaware at depths ranging from 250 to 400 feet below the land surface. The aquifer is about 250 feet thick beneath the Dover Air Force Base and is composed of fairly ...
  • Rasmussen, W.C.; Groot, J.J.; Beamer, N.H. (Newark, DE: Delaware Geological Survey, University of Delaware, 1958-08)
    Three test wells were drilled near the banks of the Chesapeake and Delaware Canal, in aquifers formed by sand beds in two geologic units, the nonmarine Cretaceous sediments and the Magothy formation, which crop out along ...
  • Rasmussen, W.C.; Wilkens, R.A.; Beall, R.M.; Others (Newark, DE: Delaware Geological Survey, University of Delaware, 1960-12)
    Sussex County is in the Atlantic Coastal Plain. Its relatively flat, featureless topography is characterized by two terrace-like surfaces; the lower one rises from sea level to about 40 feet above sea level, and the higher ...
  • DGS Staff (Newark, DE: Delaware Geological Survey, University of Delaware, 1961-02)
    In order to obtain sufficient data which will enable the State to develop its water resources to the fullest extent of which they are capable, a series of systematic investigations is necessary. A long-range plan describing ...
  • Adams, J.K.; Jordan, R.R. (Newark, DE: Delaware Geological Survey, University of Delaware, 1961-05)
  • Jordan, R.R. (Newark, DE: Delaware Geological Survey, University of Delaware, 1962-02)
    The uppermost Cretaceous and lowermost Tertiary planktonic Foraminifera obtained from cores taken in a deep well near Dover, Delaware are studied. The Cretaceous foraminifers are of the Heterohelix-Globotruncana assemblage ...
  • Jordan, R.R.; Groot, J.J. (Newark, DE: Delaware Geological Survey, University of Delaware, 1962-02)
    A series of cores was obtained from a boring in the sediments of the Delaware River near the Delaware Memorial Bridge. The mineralogy, texture and palynology of these samples have been studied. The sedimentary and palynological ...
  • Jordan, R.R. (Newark, DE: Delaware Geological Survey, University of Delaware, 1962-11)
    The stratigraphy of the Coastal Plain of Delaware is discussed with emphasis placed upon an appraisal of the stratigraphic nomenclature. A revised stratigraphic column for Delaware is proposed. Rock stratigraphic units, ...
