Datacenter water use and Irwin County Planning Commission and Industrial Authority @ WALB TV 2026-02-16

In an interview yesterday by WALB TV:

Meanwhile, WWALS Watershed Coalition Suwannee Riverkeeper John S. Quarterman said his own research raises concerns about what large-scale data centers could mean for local water resources and river health.

Quarterman said data centers typically require significant water for cooling and large amounts of electricity to operate, which he argues can indirectly affect water resources through increased demand on power generation. He said the Suwannee River Basin and surrounding aquifer systems are closely connected, meaning impacts to surface water can also affect drinking water supplies, agriculture and recreation.

Quarterman adds that water levels in some rivers and springs are already low during drought conditions, and he said he worries additional industrial demand could place further strain on natural resources.

Consent Order on JEA Buckman Wastewater Treatment Plant –FDEP 2025-09-15

This is an FDEP Consent Order on the plant that is supposed to pipe treated wastewater from Jacksonville to wetlands in the Suwannee Basin in the Water First North Florida (WFNF) project. How can such a plant be safe to water the Ichetucknee and Santa Fe Rivers and their springs? Through the Floridan Aquifer which is the source of all local water for drinking, agriculture, industry, and recreation?

According to the Florida Department of Environmental Protection (FDEP), the JEA Buckman Wastewater Treatment Plant exceeded limits on Chronic Whole Effluent Toxicity (WET), Aldrin and Total Cyanide, Fecal Coliform, Enterococci, and Ultraviolet Light Dosage, Total Recoverable Iron, Nickel, Copper, and Total Suspended Solids.

[Consent Order on JEA Buckman Wastewater Treatment Plant --FDEP 2025-09-15]
Consent Order on JEA Buckman Wastewater Treatment Plant –FDEP 2025-09-15

JEA also had to pay “$24,750.00 in settlement of the regulatory matters addressed in this Order.”

The Consent Order was issued September 15, 2025, so this is a current problem.

So it turns out the JEA Buckman plant is a typical failing wastewater treatment plant.

Does that seem safe to you for replenishing Suwannee Basin groundwater that we use for drinking, agriculture, industry, fishing, swimming, and boating?

Thanks to Joe Squitieri for sending this Consent Order. Continue reading

So-called AI hallucinates no matter how good its training data –OpenAI 2025-09-18

Update 2026-02-17: Sen. Carden Summers tries to amend to weaken GA SB 34 that would require datacenters to pay their own electric bills @ GA Sen. Comm. on Regulated Industries and Utilities 2026-02-12.

This is according to research by the creator of ChatGPT, the bot that started the “AI”boom.

Is this what we want in datacenters sucking up our water?

If not, see a previous post for some bills in the Georgia legislature.

So-called AI hallucinates, no matter how good its training data –OpenAI 2025-09-18

Gyana Swain, Computerworld, September 18, 2025, OpenAI admits AI hallucinations are mathematically inevitable, not just engineering flaws,

In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limits.

OpenAI, the creator of ChatGPT, acknowledged in its own research that large language models will always produce hallucinations due to fundamental mathematical constraints that cannot be solved through better engineering, marking a significant admission from one of the AI industry’s leading companies.

The study, published on September 4 and led by OpenAI researchers Adam Tauman Kalai, Edwin Zhang, and Ofir Nachum alongside Georgia Tech’s Santosh S. Vempala, provided a comprehensive mathematical framework explaining why AI systems must generate plausible but false information even when trained on perfect data.

“Like students facing hard exam questions, large language models sometimes guess when uncertain, producing plausible yet incorrect statements instead of admitting uncertainty,” the researchers wrote in the paper. “Such ‘hallucinations’ persist even in state-of-the-art systems and undermine trust.”

The admission carried particular weight given OpenAI’s position as the creator of ChatGPT, which sparked the current AI boom and convinced millions of users and enterprises to adopt generative AI technology.

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

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

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.

Mill Creek Sink 2025-01-13

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.

The dye trace is according to MILL CREEK and LEE SINKS DYE TRACE ALACHUA COUNTY, FLORIDA JULY-DECEMBER, 2005,

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

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.

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.
