Simple ways everyone can act to protect groundwater
Everyone can and should do something to protect groundwater. Why? We all have a stake in maintaining its quality and quantity.
• For starters, 99 percent of all available freshwater comes from aquifers underground. Being a good steward of groundwater just makes sense.
• Not only that, most surface water bodies are connected to groundwater so how you impact groundwater matters.
• Furthermore, many public water systems draw all or part of their supply from groundwater, so protecting the resource protects the public water supply and impacts treatment costs.
• If you own a well to provide water for your family, farm, or business, groundwater protection is doubly important. As a well owner, you are the manager of your own water system. Protecting groundwater will help reduce risks to your water supply.

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

Date

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. Information about this project can be found at: http://www.dgs.udel.edu/projects/evaluation-rapid-infiltration-basin-sy…

DGS releases report on subsurface geology of Delaware City area

Date

The Delaware Geological Survey (DGS) has published a report that details new findings on the subsurface geology of the Delaware City area.

Titled Subsurface Geology of the area between Wrangle Hill and Delaware City, Delaware, Report of Investigations Number 78 presents the results of cooperative research between geological consultant John W. Jengo of the firm MWH Americas and DGS researchers Peter P. McLaughlin Jr. and Kelvin W. Ramsey.

RI78 Subsurface Geology of the Area Between Wrangle Hill and Delaware City, Delaware

The geology and hydrology of the area between Wrangle Hill and Delaware City, Delaware, have been the focus of numerous studies since the 1950s because of the importance of the local groundwater supply and the potential environmental impact of industrial activity. In this report, 490 boreholes from six decades of drilling provide dense coverage, allowing detailed characterization of the subsurface geologic framework that controls groundwater occurrence and flow.

Presentation on RIBS at Fall 2012 AGU meeting

Date

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.
