DGS has released two new datasets. One dataset is a spreadsheet format file containing results of hydraulic tests from Appendix 3 of the soon to published DGS Open File Report No. 53, “Kent County groundwater monitoring project: results of subsurface exploration“.
This report presents a conceptual model of groundwater flow and the effects of nitrate (NO3-) loading and transport on shallow groundwater quality in a portion of the Indian River watershed, eastern Sussex County, Delaware. Three-dimensional, numerical simulations of groundwater flow, particle tracking, and contaminant transport were constructed and tested against data collected in previous hydrogeological and water-quality studies.
The Delaware Geological Survey (DGS) has published a new geologic map of the Millsboro and Whaleysville areas in central Sussex County titled Geologic Map of the Millsboro and Whaleysville Quadrangles, Delaware.
The geological history of the surficial units of the Millsboro Quadrangle and
Delaware portion of the Whaleysville Quadrangle was the result of deposition of the
Beaverdam Formation during the late Pliocene and its subsequent modification by
erosion and deposition related to sea-level fluctuations during the Pleistocene and late
Pleistocene upland swamp and bog deposition. The geology at the land surface was then
further modified by periglacial activity that produced dune deposits and Carolina Bays in
Scientists will sink more than 1.4 miles of wells into northern Kent County and southern New Castle County aquifers in the coming year, hoping to pump out a flood of new information about groundwater quantity and quality in current and future growth areas.
