Delaware Geological Survey releases new geologic map of Harbeson area

Date

The Delaware Geological Survey (DGS) has published a new geologic map of the area east of Georgetown in Sussex County entitled Geologic Map of the Harbeson Quadrangle, Delaware. Geologic Map 17 presents the results of research by Kelvin W. Ramsey and Jaime L. Tomlinson of the DGS.

The map shows and describes the geologic units found at the land surface and in the shallow subsurface in the map area. The map includes cross sections that show stratigraphic units that lie beneath the surficial units and detailed descriptions and ages of all units presented on the map.

DNREC raises capital request - Sixfold hike includes beach, water projects

Date

More money would go to projects that make Delaware cleaner, greener and safer under a mostly no-growth budget outlined Monday by the Department of Natural Resources and Environmental Control. Agency Secretary Collin P. O'Mara asked the Office of Management and Budget for about $35.2 million in general funds for the fiscal year that begins July 1, with health care costs accounting for most of the nearly $2 million increase from the current year.

Wastewater Reuse: Benefits and Risk Assessment in Inland Bays Indian River Basin

Project Contact(s)

The goal of this project is to develop a three-dimensional (3D) numerical groundwater flow model to evaluate the potential impacts to surface- and groundwater resulting from the disposal of treated wastewater in a portion of the Inland Bays drainage basin.

By developing a sub-regional, fresh, groundwater flow model and analyzing results, several issues will be addressed that are related to state policy, regulation revision, and proposed projects associated with land-based wastewater disposal (LBWD) in Sussex County.
