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.
The DGS has begun a multi-year project to install new groundwater monitoring infrastructure and collect baseline data in Sussex County, Delaware. This project is a continuation of a larger effort to construct a statewide groundwater monitoring network.
Groundwater is the sole source of drinking water and the main source of water for agriculture and industry in central and southern Delaware. This study mapped the depth and thickness of thirteen aquifers in Kent and Sussex Counties, used these maps to assign groundwater withdrawals for 2004 to 2008 to the appropriate aquifer, and analyzed withdrawals for each type of water use by geographic area.
Due to low elevation and a shallow water table, the Delaware Bay coast is highly vulnerable to sea-level rise. Numerical simulations of rising sea levels, groundwater flow, and salt transport through year 2100 indicate significant impacts on land use due to a rising water table and localized impacts due to saltwater intrusion in the surficial aquifer.
