Monitoring wells and groundwater sensors were installed and monitored in and around Holts Landing State Park on the Indian River Bay, eastern Sussex County, Delaware, between October 2009 and August 2012. Data from test drilling, geophysical logging, geophysical surveys, and well testing characterized the hydrogeological framework and spatial and temporal patterns of water pressure, temperature, and salinity in the shallow, unconfined Columbia aquifer. The work revealed a plume of freshened groundwater extending more than 650 ft into the bay from the shoreline.
DGS staff member A. Scott Andres made a presentation “Results of selected UD nutrient monitoring projects in the Nanticoke River watershed” at the inter-agency meeting Chesapeake basin water quality data, trends, and interpretations held August 11, 2016 at the Delaware Department of Agriculture in Dover.
David Wunsch, the state geologist for Delaware and director of the Delaware Geological Survey, served as a special consultant for the U.S. State Department at the South Asia Groundwater Forum in Jaipur, India, June 1-3.
The meeting, hosted by the government of India, in partnership with the World Bank and the International Water Association, brought together regional government and non-government stakeholders and experts from water, agriculture, energy and environmental sectors.
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.
