DGS and Delaware Environmental Observing System (DEOS) staff are pleased to announce that real-time groundwater level data from well Cb51-184 located next to the DEOS weather station on the University’s College of Agriculture Newark campus are now available. Recent data from the well can be accessed on the DEOS web site through this link deos.udel.edu/station/index.php?station=DAGF. Graphical and text displays of groundwater levels are updated hourly. A link to the DEOS page is also present on the DGS Water Resources web page (https://www.dgs.udel.edu/water-resources), making it convenient for DGS web site users to quickly find the data.

Cb51-184 is the fourth well in the DGS Groundwater Monitoring Network that provides real-time data. The others are Oh51-09 at Harbeson (DE-REC), operated by the DGS, and Pe54-51 at Jones Crossroads (DE-SSWMC) and Kb32-75 at Sandtown (DE-CSWMC) which are operated in cooperation with the Delaware Solid Waste Authority. All of these wells are in the Columbia aquifer and provide water table depth data. Real-time data are available from three additional wells operated by the US Geological Survey (https://waterdata.usgs.gov/de/nwis/current/?type=gw&group_key=NONE)

These real-time data can be useful for predicting and responding to flooding conditions such as occurred at Harbeson in September 2016 (see http://www.dgs.udel.edu/news/groundwater-response-extreme-rainfall-even…). For assessment of longer term trends, and current water conditions processed data and statistics from our groundwater monitoring network are updated on the DGS Water Resources Page at http://www.dgs.udel.edu/sites/default/files/data/recent-and-historical-… every few months.
