16th Annual National Groundwater Awareness Week - March 9-15, 2014

Date

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.

East Dover Groundwater Flow Model

Project Contact(s)

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).

RI80 Investigation of Submarine Groundwater Discharge at Holts Landing State Park, Delaware: Hydrogeologic Framework, Groundwater Level and Salinity Observations

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.
