University assists with Delaware GIS Day field trip

The Earth Balloon was a popular feature at Delaware GIS Day.

Volunteers from the University of Delaware and the UD-based Delaware Geological Survey assisted with the Delaware GIS (Geographic Information Systems) Day field trip for fifth graders held Nov. 18.

RI40 Sodium Concentrations in Water from the Piney Point Formation, Dover Area, Delaware

RI40 Sodium Concentrations in Water from the Piney Point Formation, Dover Area, Delaware

In the greater Dover area sodium concentrations in ground water from the glauconitic Piney Point Formation commonly exceed 100 parts per million. Investigation of chemical characteristics of the water, and statistical analyses of the results, show that these high concentrations are due to a natural ion-exchange process. Calcium in water replaces sodium in the mineral glauconite and causes the sodium enrichment in ground water.

RI34 Long-Term Chemical-Quality Changes in Selected Delaware Streams

RI34 Long-Term Chemical-Quality Changes in Selected Delaware Streams

Data from three streamflow water-quality stations were statistically analyzed to determine the relationships of the major inorganic chemical constituents to specific conductance and to stream discharge. The results show that ion concentrations varied directly with the flow and with specific conductance. A set of regression equations defining these relationships were derived for each of the three stations: Brandywine Creek at Wilmington, St. Jones River at Dover, and Nanticoke River near Bridgeville.

B17 Geological Studies of Cretaceous and Tertiary Section, Test Well Je32-04, Central Delaware

B17 Geological Studies of Cretaceous and Tertiary Section, Test Well Je32-04, Central Delaware

A cored well 1,422 feet (433 meters) deep drilled two miles southeast of Dover is the basis for this integrated study of the lithology and paleontology of the Cretaceous-Tertiary section in central Delaware. The section is subdivided into lithostratigraphic, biostratigraphic, chronostratigraphic, and heavy mineral units. Data and results are presented on a common base in three plates.

RI26 Hydraulic Characteristics of the Piney Point Aquifer and Overlying Confining Bed near Dover, Delaware

RI26 Hydraulic Characteristics of the Piney Point Aquifer and Overlying Confining Bed near Dover, Delaware

The hydraulic properties of the Piney Point (Eocene) aquifer and overlying basal silt of the Chesapeake Group (Miocene) were determined by a 23-day aquifer test conducted at the Danner Farm Well Field of the City of Dover, Delaware. During the test, head changes were monitored continuously in the Piney Point aquifer, overlying Cheswold (Miocene) aquifer, and the intervening confining bed.

GM14 Geologic Map of Kent County, Delaware

GM14 Geologic Map of Kent County, Delaware

This map shows the surficial geology of Kent County, Delaware at a scale of 1:100,000. Maps at this scale are useful for viewing the general geologic framework on a county-wide basis, determining the geology of watersheds, and recognizing the relationship of geology to regional or county-wide environmental or land-use issues. This map, when combined with the subsurface geologic information, provides a basis for locating water supplies, mapping ground-water recharge areas, and protecting ground and surface water. Geologic maps are also used to identify geologic hazards, such as flood-prone areas, to identify sand and gravel resources, and to support state, county, and local land-use and planning decisions.

RI2 High-Capacity Test Well Developed at the Air Force Base, Dover, Delaware

RI2 High-Capacity Test Well Developed at the Air Force Base, Dover, Delaware

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 uniform medium to fine glauconitic quartz sand. The static water level in a test well at the
