In cooperation with DelDOT, DGS is investigating the physical and chemical impacts of de-icing practices (salting and brining) and stormwater infiltration best management practices (BMP) on groundwater.
The Delaware Geological Survey (DGS) has measured, managed, and distributed groundwaterlevel data for several decades using widely accepted procedures and practices, many of which were derived from interactions with staff of the USGS, consulting firms, and other state agencies. Many of the individual methods and procedures have been described in DGS reports, however, written documentation for these tasks have not been assembled in a single published document.
The DGS has been a data provider for the National Ground-Water Monitoring Network (NGWMN) since 2016. NGWMN is a consortium of state and local agencies and the U.S.
DGS and DEOS are pleased to announce that near real-time groundwater level data from well Oh25-09 have recently been made available on the DEOS web site through the Harbeson, DE-REC station found on the Current Conditions link (http://
