Assessing Potential Impacts of a Wastewater Rapid Infiltration Basin System on Groundwater Quality: A Delaware Case Study

DGS staff member A. Scott Andres along with J. Thomas Sims of the University’s Department of Plant and Soil Science have had a paper “Assessing Potential Impacts of a Wastewater Rapid Infiltration Basin System on Groundwater Quality: A Delaware Case Study” published in the Journal of Environmental Quality. This paper is the latest technical report from a DGS-led project “Evaluation of Rapid Infiltration Basin Systems (RIBS).” Four additional reports on this project are nearing release in the DGS bulletin series.

Delaware Geological Survey releases new geologic map of Harbeson area

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.

DGS honors retiring director, state geologist Talley

Talley is retiring after 38 years of service

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.

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

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

Study domain
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.

A GIS screening tool for assessing suitability of land for RIBS

Scott Andres and Edward Walther, of the Delaware Geological Survey, presented "Development and Application of a GIS Screening Tool for Assessing Suitability of Land for Rapid Infiltration Basin Systems" at the National Ground Water Association Summit, Denver, April 12-15. Andres also participated in a panel discussion co-sponsored by the U.S. Subcommittee on Groundwater, "National Groundwater Monitoring Network: Listening Session."
