Hahira, Georgia, January 12, 2026 — For thirty years it was suspected that the Okefenokee Swamp leaks water into the groundwater from which we all drink. Now we have much stronger evidence, that the Swamp leaks not a little but a lot of water into the Floridan Aquifer.
At noon by zoom this Thursday, you can watch the UGA professors who published it explain that evidence.
They will also mention some consequences, such as nearby water withdrawals pull more water from the Swamp into the Aquifer.
Lead author Prof. Jaivime Evaristo will explain the isotope evidence. Prof. Todd Rasmussen will explain the water level evidence.

At noon, January 15, 2026, Suwannee Riverkeeper John S. Quarterman will give a brief introduction.
Prof. Evaristo and Rasmussen will speak for about 45 minutes.
Questions and answers will be at the end.

Here is more about their paper:
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:
