The Floridan Aquifer is our main drinking water source under our entire WWALS watershed, east to south Carolina, west through Alabama to Mississippi, and under all of Florida.

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

Leave a reply

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.

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

2 Replies

Do you think a billion dollars to pipe treated wastewater from Jacksonville into the Suwannee Basin is a bad idea?

If so, please ask your statehouse delegation and Water Management District Board to explain why limiting water withdrawals would not be a better idea, or to stop this project.

Everybody is downstream from somebody else. But we don’t need the Suwannee River Basin to be downstream from Jacksonville. Sure, we’re poorer than Jacksonville, but we’re not their sacrifice zone.

Two Water Management Districts say this Water First North Florida project would replenish levels and flows in the Lower Santa Fe and Ichetucknee Rivers, including the Ichetucknee Headspring, by sending water into the Upper Floridan Aquifer through wetlands.

How can this expensive and risky project be the best way to conserve levels and flows in these Outstanding Florida Waters, which are supposed to be worthy of special protection because of their natural attributes?

How can risking the source of our drinking water be a good idea?

Also ask SRWMD to hold a Public Hearing explaining why this project is better and safer than limiting water withdrawals.

UGA Professors Jaivime Evaristo (isotope data) and Todd Rasmussen (water levels) review two lines of evidence that the Okefenokee Swamp leaks through the underlying limestone into the Upper Floridan Aquifer, and nearby water withdrawals draw more down.

This WWALS Webinar by zoom at noon will explain their recent scientific paper on this subject.

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 →

Valdosta groundbreaking on additional drinking water plant 2025-12-18

Valdosta has been talking about building a second drinking water plant for a long time, and this week they broke ground for it, just south of Valdosta Airport.

That’s a good thing, since it helps direct development close in to Valdosta, instead of sprawling into agricultural and forestry land.

Everyone please note: drinking water plant. Not wastewater plant.

[Valdosta groundbreaking on additional drinking water plant, on Race Track Road SE, South of Valdosta Airport]
Valdosta groundbreaking on additional drinking water plant, on Race Track Road SE, South of Valdosta Airport

Here’s hoping Valdosta’s contractors tested sufficiently to be sure the new wells will not draw in river water, like what happened at the old drinking water plant on Guest Road, where they had to sink the wells twice as deep.

Also, we shall see what effect withdrawing 2.5 million gallons a day of groundwater will have. This plant appears to be under the same permit number, GA1850002, as the old one.

Valdosta posted a YouTube video, with voiceover by Mayor Scott James Matheson:

https://youtu.be/8x-mtomtSX8?si=uGSwUsWMCJCj_Q5G

The Mayor said the plant may help direct growth to the south side of Valdosta. That is something that has been lacking for a long time.

The Mayor posted some pictures on facebook, including this one. 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.

Okefenokee Swamp exchanges water with the Floridan Aquifer –peer-reviewed evidence 2025-12-09

Update 2025-12-26: WWALS Webinar via zoom: Okefenokee Swamp leaks into the Floridan Aquifer, Prof. Evaristo & Rasmussen, 2026-01-15.

University of Georgia (UGA) Professor Todd C. Rasmussen is back after 30 years with peer-reviewed double evidence that the Okefenokee Swamp does exchange water with the underlying Floridan Aquifer from which we all drink in south Georgia and north Florida.

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.

[Packet: SRWMD Board, Live Oak, FL 2025-12-09, plus Workshop on Drought Conditions]

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 →

Videos: Bradford Road Denied @ Berrien County Commission 2025-11-04

The Berrien County Commission denied the subdividing issue before them: the six lots on Bradford Road, at their November 4, 2025, regular meeting.

However, many irregularities were raised.

[Bradford Road Denied @ Berrien County Commission. Many irregularities raised, 2025-11-04]
Bradford Road Denied @ Berrien County Commission. Many irregularities raised, 2025-11-04

The other lots on Old Valdosta Highway were already decided by the same Commission in 2024, and the minutes for that meeting say at the request of John and Tonia Beville.

At this meeting, John Beville said he and she had not requested that, and never saw any Public Hearing signs posted, even though they lived there at the time. When questioned by the Commission, Zoning Coordinator Teresa Willis said it was done for South Auction, and “Russ” brought the plat to her. She did not say who Russ was.

Della Gladieux pointed out that the three Planning Commission Public Hearings this year all had both plats advertised, for the lots on Old Valdosta Highway, and for the other lots on Bradford Road. She also pointed out other issues in the document she handed the Commissioners: Formal Complaint and Demand for Investigation Re Bradford Road –Della Gladieux 2025-11-04.

Lisa Sumner also spelled out numerous issues.

Below you can see the entire Berrien County Commission meeting of November 4, 2025 in the WWALS videos of each agenda item and speaker, plus a few still pictures, followed by a WWALS video playlist.

Drought in Suwannee River Basin? 2025-11-17

Update 2025-12-06: Packet: SRWMD Board plus Workshop on Drought Conditions 2025-12-09.

Why hasn’t SRWMD declared a drought yet?

According to the U.S. Drought Monitor, the entire Suwannee River Basin in both Georgia and Florida is in drought.

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

With the Floridan Aquifer and intermediate aquifers already low, reducing withdrawals would be prudent before some wells run dry and sinkholes appear.

SRWMD posted their monthly press release about the Hydrologic Conditions Report on November 17, 2025.

[Drought in Suwannee River Basin? Low Rain, Rivers, and Wells 2025-11-17, Aquifer starting to be low, What is the threshold?]
Drought in Suwannee River Basin? Low Rain, Rivers, and Wells 2025-11-17, Aquifer starting to be low, What is the threshold?

In the linked October 2025 Hydrologic Conditions Report, page 2:

CLIMATE AND DROUGHT OUTLOOK

La Niña conditions are present and favored to persist from December 2025 to February 2026, with a 55% chance of ENSO-neutral transition between January and March 2026.

The NOAA three-month seasonal outlook suggests above normal temperatures and below normal precipitation within the District from November 2025 to January 2026.

The U.S. Drought Monitor report released on Thursday, November 6th, shows Abnormally Dry (D0) conditions in the southern Levy County, Moderate Drought (D1) and Severe Drought (D2) indices across most central District counties, and Extreme Drought (D3) in all of Hamilton and parts of Suwannee, Columbia, Madison, and Jefferson counties.

That DM report was two weeks ago. And the Drought Monitor report released today, November 20, 2025, with data valid through November 18, 2025, shows Extreme Drought through all the Suwannee River Basin counties along the GA-FL line, adding parts of Baker, Alachua, and Lafayette to the above list, and Severe or Moderate Drought for the rest. Even Levy County no longer has any D0 conditions: it is completely D1 for Moderate Drought. Continue reading →
