Thanks to UGA Professors Jaivime Evaristo (isotope data) and Todd Rasmussen (water levels) for reviewing their two lines of evidence that the Okefenokee Swamp leaks through the underlying limestone into the Upper Floridan Aquifer.
This webinar explains their recent scientific paper on this subject.
Note that this means that nearby water withdrawals draw more water down from the Swamp into the Aquifer.
This paper is more incentive to pass Georgia House Bill 561 to protect the Okefenokee Swamp from mining, at least on its east side. Georgians, please ask your statehouse delegation to pass HB 561. Floridians, please ask your Georgia friends and relatives to do the same. Here’s how to contact Georgia Statehouse members:
