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.

NGWA Protect Your Groundwater Day

Date

September 11, 2012 is Protect Your Groundwater Day. This annual recognition is promoted by the National Ground Water Association (NGWA) to spotlight how individuals can protect and reduce health risks to an important drinking water source for rural America—groundwater.

Monitoring our water - Delaware Geological Survey improving groundwater monitoring efforts with new wells, sampling

Date

Delaware Geological Survey improving groundwater monitoring efforts with new wells, sampling. Scientists are digging for answers about the amount and quality of water available underground in central Delaware, where ongoing development will put increasing demands on water supplies in the coming decade.

The Delaware Geological Survey (DGS) is installing 7,700 feet of wells at eight sites in southern New Castle and northern Kent counties to improve groundwater-monitoring efforts, supported by a $600,000 grant from the Delaware Department of Natural Resources and Environmental Control (DNREC). Groundwater is the primary source of drinking water south of the Chesapeake and Delaware Canal, and populations there are projected to continue expanding.

Effect of tropical storms Irene and Lee on groundwater levels in well Qb35-08

Tropical storms Irene and Lee caused a 9-1/2 foot rise of the water table in western Sussex County near Laurel. Groundwater levels and temperatures in Qb35-08 were collected with an automated pressure-temperature datalogger system. At the same time, rainfall and soil moisture data were recorded by the DEOS Laurel Airport station located approximately 5 miles from the well.

David R. Wunsch appointed DGS Director

After a nationwide search, David R. Wunsch has been appointed the next Director of the Delaware Geological Survey (DGS) and Delaware State Geologist, effective Nov. 1. He will succeed John H. Talley, who retired on June 30 after more than 38 years of service. Wunsch holds a doctorate in hydrogeology from the University of Kentucky, a master’s degree in geology from the University of Akron, and a bachelor’s degree in geology, with a minor in chemistry, from the State University of New York, Oneonta. In 2011, Wunsch was elected a Fellow of the Geological Society of America. He is an Honorary Member and a past President of the Association of American State Geologists (AASG) and has previously served a term as Secretary of the American Geological Institute.
