AGS Monthly Meeting

April 25, 2023 @ 6:00 pm - 8:00 pm

Speaker: John Clarke, Retired Assistant Director, U.S. Geological Survey (USGS), Ga Water Science Ctr.

Topic: Georgia’s groundwater wars

Abstract: Water is the lifeblood of our planet. Throughout history to the present day, wars have been waged over this precious resource, and Georgia is no exception.  The presentation will provide an overview of conflicts over groundwater resources of Georgia and adjacent South Carolina, Alabama, and Florida. This includes saltwater intrusion along the coast, groundwater contamination at the Savannah River Site, and effects of agricultural pumping on streamflow in the Chattahoochee-Flint River Basin.

Speaker Bio: John Clarke retired in 2014 after a 35-year career with the USGS Georgia Water Science Center. As hydrologist and Assistant Director for Hydrologic Investigations, he authored more than 50 papers on Georgia groundwater, and twice served as president of the Georgia Ground Water Association. Notable project work included assessment of groundwater contaminants at the Savannah River Site; development of a hydrologic overview of Israel, Jordan, and Palestinian territories as part ongoing peace initiatives; and design and implementation of the Georgia Coastal Sound Science Initiative to assess coastal area groundwater resources and address issues of salt-water intrusion and resource sustainability.
