Did you know that DGS offers real-time groundwater level data? This service, operated in collaboration with the Delaware Environmental Observing System (DEOS) and the Delaware Solid Waste Authority (DSWA) has been available for several years. The most recent one-week of provisional data from three shallow wells in the Columbia Aquifer are easily accessed thru links to DEOS on the water resources page of the DGS web site at https://www.dgs.udel.edu/water-resources. The DEOS data access page then offers options to view data as a hydrograph and to download data in several graphics or data formats.

Well Kb32-75, installed in 2006, is located at the Central Solid Waste Management Center in Kent County. Well Oh51-09, installed in 2015, is located at the University of Delaware, College of Agriculture’s Warrington Farm in Sussex County, and well Pe54-51, installed in 2011, is located at the Southern Solid Waste Management Center in Sussex County. Each of these wells was installed by the DGS. DGS staff chose these sites because of the willingness of the landowner to allow long-term access, easy access to real-time data telemetry systems, but of equal importance, to be co-located with a multi-sensor weather station that facilitates direct comparison of groundwater response to weather conditions. An example of such a comparison appeared as a DGS news item in 2016, https://www.dgs.udel.edu/news/groundwater-response-extreme-rainfall-eve…

Similar to real-time data provided by the US Geological Survey, it is important to recognize that the real-time groundwater level data are considered provisional until DGS staff perform additional quality control operations. Fully processed and quality controlled long-term data and well metadata are available from the same location as other DGS-provided groundwater level data at:

The Delaware Geological Survey operates a groundwater monitoring network and provides the data to inform and educate resource managers and the public to better understand and manage our water resources.
