A poster "Modeling Engineered Approaches to Enhance Denitrification under Rapid Infiltration Basins" resulting from a collaborative research project between Paul Imhoff, Maryam Akhavan (UD Civil&Environmental Engineering), A. Scott Andres (DGS), and Stefan Finsterle (Lawrence Berkley National Lab) was presented at the Fall 2012 AGU meeting in San Francisco, CA on Dec. 3.
Two Delaware Geological Survey staff members attended the Source Water Assessment and Protection Program meeting held Sept. 14 in Dover, Del. Scott Andres made a presentation titled "Results of Field and Lab Experiments on High Rate Land Application of Wastewater" and John Callahan made a presentation titled "Web-Delivered Application for Hydrogeologic Data."
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.
John Talley joined the Delaware Geological Survey as a project geologist in 1972, became a senior scientist and hydrogeologist by 1986, and rose to director and state geologist by 2004. He’s consulted with dozens of university, state, and federal governments and groups and amassed a list of more than 50 publications and reports.
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.
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.
