The 16th annual National Groundwater Awareness Week will take place March 9-15, 2014. This is a time when National Ground Water Association (NGWA) and its partners educate the public about the resource of groundwater, its importance to public health, quality of living, and the environment, and for those who rely on groundwater from a household water well—how to take care of their water well system.
In 2015, DGS became aware of a situation east of Dover where there is potential for overpumping of the Columbia aquifer by the City of Dover’s Long Point Road wellfield (LPRW) and numerous large-capacity irrigation wells in the surrounding area (Figure 1).
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.
