Video: Okefenokee Swamp leaks into the Floridan Aquifer peer-reviewed evidence, WWALS Webinar, 2026-01-15

2 Replies

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:

Six hours and no decision @ Alachua Planning Commission 2026-01-13

1 Reply

Update 2026-01-20: In the next meeting, Tuesday, January 20, 2026, the vote was 4:0 to deny, by the City of Alachua Planning and Zoning Commission. So it’s dead for now, but watch for it to come back later.

The City of Alachua Planning Commissioners seemed inclined to approve the Special Exception Permit for the Tara April detention ponds and trails next to I-75.

But after the applicant’s case was countered by the National Speleological Society (NSS) and others, the Commissioners seemed ready to deny.

However, at midnight the court recorder had to leave, so they had to adjourn until Tuesday, April January 20, 2026, at 6 PM, also at Alachua City Hall, 15100 NW 142 Terrace, Alachua, FL 32615.

Get there early. It was standing room only this Tuesday, with some people outside the doors.

Update 2026-01-17: Six hours and no decision @ Alachua Planning Commission 2026-01-13.

It took about 12 days for dye put into Mill Creek Sink to show up six miles northwest in Hornsby Spring. That spring is on the far side of High Springs. It runs into the Santa Fe River.

Anything that goes into Mill Creek Sink could affect drinking water for the city of High Springs, as well as Hornsby Spring and the Santa Fe River. And probably other things nearby over the Floridan Aquifer.

Update 2025-01-17: Video.

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.

The Floridan Aquifer in North Carolina 1996-01-01

Is Columbia, South Carolina, in the Floridan Aquifer?

Doesn’t look like it. But thanks for the question.

[Does the Floridan Aquifer include Columbia, SC? Apparently not. Nor the Tertiary sand aquifer.]
Does the Floridan Aquifer include Columbia, SC? Apparently not. Nor the Tertiary sand aquifer.

A WWALS member shared a post from Congaree Riverkeeper, asking,

“the Floridan Aquifer source, or terminus? Anyway, in S.C….”

The Congaree Riverkeeper post said:

We got out and did river patrol on the Broad River the other day.

We were able to check on a few projects happening along the river, including the construction of the City of Columbia’s new drinking water intake….

The Broad River comes down south into Columbia, SC, where it joins the Congaree River. Lake Murray just to the west of Columbia is easy to recognize on many of the other maps below. Continue reading →

Water First North Florida wetland locations: unknown –SRWMD 2025-12-17

Update 2026-01-08: SJRWMD hired a consultant to plan piping treated Jacksonville wastewater into the Suwannee River Basin (Water First North Florida) 2025-11-12.

Update 2026-01-03: Ask Florida statehouse and Water Districts to explain JAX treated wastewater into the Suwannee Basin or to stop it 2026-01-02.

Here’s a bit more about the Water First North Florida (WFNF) billion dollar project to pipe treated wastewater from Jacksonville into the Suwannee River Basin.

The Suwannee River Water Management District (SRWMD) seems to know surprisingly little about this joint project with the St Johns River Water Management District (SJRWMD).

They don’t know where the water would go into wetlands to “clean” it up some more, and they don’t know where it would go to infiltrate into the Floridan Aquifer.

They don’t have a pilot study and they don’t have wetland site assessments.

Turns out there are a couple of reasons why SRWMD does not know or have those things. But I have found out a few things.

And I have leads to find out much more.

Back on July 8, 2025, SRWMD Deputy Executive Director of Water Resources Amy Brown gave her board a Lower Santa Fe and Ichetucknee Project Update. It included a few slides on the WFNF, aka North Florida Regional Recharge Project. Continue reading →

Drought Workshop Presentation –SRWMD 2025-12-09

Update 2026-01-08: Water Shortage Advisory Order on agenda @ SRWMD 2026-01-13.

Update 2026-01-03: Ask Florida statehouse and Water Districts to explain JAX treated wastewater into the Suwannee Basin or to stop it 2026-01-02.

Update 2025-12-18: Water First North Florida wetland locations: unknown –SRWMD 2025-12-17.

In their Drought Conditions Workshop on December 9, 2025, SRWMD talked about starting an outreach campaign, “highlighting the water deficit that we are in, and our drought, and the need for efficiency, and here are some possible measures that you could implement, from a voluntary standpoint.”

But they are not yet willing to declare even the statutory Water Shortage Warning or Advisory, which has only voluntary measures.

[Drought Workshop Presentation --SRWMD 2025-12-09, No water withdrawal limits yet, Maybe an outreach campaign soon]

If the current drought is not severe enough to warrant even a statutory Warning, why are SRWMD and SJRWMD forging ahead with their billion-dollar Water First North Florida project to pipe treated Jacksonville wastewater into the Suwannee River Basin to recharge the Floridan Aquifer here? And what is being done to remove the PFAS, drugs, and articifical sweeteners that typically pass right through wastewater treatment?

Thanks to SRWMD Board members Charles Keith, Larry Sessions, and William Lloyd, they did talk about possibly instituing limits on water withdrawals, considering that the past 10 years have been the hottest on record.

The presenter, Amy Brown, Deputy Executive Director, Water Resources, was clear that they have not even advised voluntary limits for the biggest group of users, which are in agriculture.

Her slides, received from SRWMD in response to a WWALS public records request, are on the WWALS website, with images below in this post.

SRWMD Executive Director Hugh Thomas did note that the water withdrawal permits SRWMD issues have standard conditions that can require limits on water withdrawals. But “it’s never fun to engage with the permittee and say, hey, you’re going to have to cut back because we’re in a water shortage period.”

You can see Amy Brown, Deputy Executive Director, Water Resources, present these slides to the SRWMD Board in their own video of their December 9, 2025, Workshop, at 1:45:58:

https://www.youtube.com/live/6LDIIdFqxaY?si=LnRZUqNL0imphDJz&t=6358

What about reducing water withdrawals?

At 2:14:10, you can hear Charles Keith asking about increasing drought. Continue reading →

Hydrologic Conditions Report –SRWMD 2025-11-30

Update 2025-12-17: Drought Workshop Presentation –SRWMD 2025-12-09.

Every county in the Suwannee River Basin is in drought, according to SRWMD’s own Hydrologic Conditions Report for November 30, 2025 presented in their Board meeting of December 9, 2025.

But not droughty enough for SRWMD to declare even a voluntary Drought Warning, according to the Drought Workshop after the Board meeting. I have sent in a FOIA request for the Workshop slides. Both meetings are in the SRWMD YouTube post for 2025-12-09.

https://www.youtube.com/watch?v=6LDIIdFqxaY

Meanwhile, here is the SRWMD Hydrologic Conditions Report for November 2025, plus some related information.

Such as SRWMD actually does have “Year-Round Lawn & Landscape Irrigation Measures,” but nobody seems to know about them. And that page does not seem to include agricultural, mining, or water bottling water use. Continue reading →

Packet: SRWMD Board plus Workshop on Drought Conditions 2025-12-09

Update 2025-12-17: Drought Workshop Presentation –SRWMD 2025-12-09.

Update 2025-12-14: Hydrologic Conditions Report –SRWMD 2025-11-30.

Maybe you’d like to come to the Workshop on “Drought Conditions and Review of the District’s Water Shortage Process” that the Suwannee River Water Management District (SRWMD) is holding. That’s this Tuesday, December 9, 2025, at 9 AM in Live Oak, after the SRWMD Board meeting.

If I’m not mistaken, a drought declaration by the Suwannee River Water Management District would mean numerous water withdrawal permit holders would have to reduce their withdrawals.

Also, Board agenda item 26. Water Resources Division Updates, will probably include an update on the Water First North Florida billion-dollar aquifer recharge project. It would pipe treated wastewater from Jacksonville to wetlands in the Suwannee River Basin, and from there into sinks to recharge Ichetucknee Headspring and maybe others. Limiting water withdrawals would be less expensive and more effective, without risking contaminating our springs and aquifers with PFAS and other chemicals that wastewater treatment does not remove.

Two weeks ago I asked, Why hasn’t SRWMD declared a drought yet?

Already then, according to the U.S. Drought Monitor, the entire Suwannee River Basin in both Georgia and Florida was in drought.

Conditions have only gotten worse since then. Continue reading →
