A recently released article “Hydrogeologic controls on groundwater discharge and nitrogen loads in a coastal watershed” by the Journal of Hydrology details the results of a joint groundwater simulation and water quality sampling study that focused on submarine groundwater discharge (SGD) to Indian River and Rehoboth Bays, part of Delaware Inland Bays.
David R. Wunsch, Delaware’s State Geologist and Director of the Delaware Geological Survey, presented a paper titled “Going with the Flow: Federal Funding Facilitates Progress for the U.S. National Ground-Water Monitoring Network” at the National Groundwater Association’s Groundwater Summit on Monday, April 25, in Denver Colorado.
David Wunsch, the Director of the Delaware Geological Survey, attended the Annual Pick & Gavel award banquet at the historic Cosmo’s Club in Washington, DC. The Pick & Gavel Award is presented by the Association of American State Geologists (AASG) to a national public policy official or other leader who has demonstrated support, leadership, and advancement of the geosciences in the public policy arena. This year's winner was Anne J. Castle, the former Assistant Secretary for Water and Science in the Department of Interior under President Obama. Dr. Wunsch was Ms. Castle’s nominator, and served as citationist and presented Secretary Castle with her award. Previous winners include U.S. Senators, Congressmen, and executive agency leaders.
Groundwater is essential to the health and well-being of humanity and the environment. Whether you’re on a public water system or a private well, whether you are a health care official, policymaker, regulator, an environmentalist or a groundwater professional, you can get involved in protecting this vital resource.
The Delaware Geological Survey released a new technical report entitled “Groundwater Quality and Monitoring of Rapid Infiltration Basin Systems, Theory and Field Experiments at Cape Henlopen State Park, Delaware” which was prepared by A. Scott Andres and Changming He of the Delaware Geological Survey, Edward Walther of the South Water Management District, Florida, Müserref Türkmen of the Izmir Water and Sewerage Administration, Turkey, and Anastasia Chirnside and William Ritter of the University of Delaware. DGS Bulletin 21C documents the results of a detailed study of groundwater quality at a rapid infiltration basin system.
A rapid infiltration basin system (RIBS) consists of several simple and relatively standard technologies; collection and conveyance of wastewater, treatment, and discharge to an unlined excavated or constructed basin. By design, the effluent quickly infiltrates through the unsaturated or vadose zone to the water table. During infiltration, some contaminants may be treated by biological and/or geochemical processes and diluted by dispersion and diffusion.
