Aquifer recharge is needed, but Jacksonville pumping is the biggest problem –Dennis J. Price, P.G. 2026-02-22

This was an op-ed in the Lake City Reporter, February 19, 2026, by Dennis J. Price, P.G., of Hamilton County, Florida. It’s about Water First North Florida (WFNF), the SRWMD and SJRWMD plan to pipe treated wastewater from Jacksonville into wetlands in the Suwannee River Basin.

He does not want the Suwannee River Basin to continue to be a giant water tower for Jacksonville, through the Floridan Aquifer. He suggests JEA could get drinking water from the St. Johns River instead of withdrawing it from groundwater.

Of JEA could get on with seawater desalination, as south Florida already does.

LETTERS TO THE EDITOR

Aquifer recharge is needed

To the editor:

Recently the Suwannee River Water Management District (SRWMD) proposed a plan to recharge water into our drinking water aquifer, the Floridan Aquifer. The plan is being coordinated with the St. John’s River Water Management District (SJRWMD). Duval County has a private company that supplies almost all the water used in Duval County. With the city of Jacksonville and outlying suburbs using most of that water, the company is the Jacksonville Electric Authority (JEA). The SJRWMD is the permitting authority that controls the amount of water the JEA can pump. There are practically no restraints placed on the JEA. The amount of water the JEA pumps is enormous, 120 million gallons per day. Growth in Duval County is growing rapidly, extending those suburbs towards and into Baker County.

Aquifer recharge is needed –Dennis J. Price, P.G. 2026-02-22, but Jacksonville pumping is the biggest problem

Our aquifer is in limestone. It is cracked and fissured by several processes that occurred over the past several million years. The amount of cracks and connected fissures determine how fast water can move through the aquifer. The aquifer under Duval County has 2 problems. It doesn’t flow quickly from the north and from the south to the pumps and the Atlantic Ocean on the east is a barrier to fresh water flow. But water does flow easier from west to east, in other words from our direction to Jacksonville. Jacksonville is faced with a water problem. The wells closest to the coast are pulling salt water into the wells. USGS studies from 1990 based on 1980’s data shows that Jacksonville was already pulling water from underneath us and flowing to them. They have begun to move their production wells closer to Baker County. With Jacksonville’s growth, these new wells produce more water and therefore draws down the water in our aquifer.

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.

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 →

Alapaha Sturgeon Rescue –Kenneth Sulak 2010-09-12

Ken Sulak sent this story today, about rescuing Gulf Sturgeon from the dry bed of the Alapaha River, back in September 2010.

The Alapaha River often goes dry in late summer and fall, because what little water it has after evapotranspiration goes down the Dry River distributary into the Dead River Sink, and only emerges about 19 miles downstream at the Alapaha River Rise and Holton Creek Rise, both on the Suwannee River upstream from the Alapaha River Confluence.

Dug deep into photo files – found a few images from 12-13 Sept 2010 rescue of 4-5 sturgeon stranded in a pool in the otherwise dry Alapaha. I no longer have access to USGS files since the current regime has decided to cutoff all retired emeritus scientists from their stored data. So I could not determine exactly where this was located, exact number of fish rescued, or their lengths. This was a 2-day effort. I will ask Mike Randall to pull up the field logs and see if he can find the relevant data.

Sturgeon Rescue from Dry Alapaha River –Kenneth Sulak while at USGS, September 12-13 2010

We drove in on an SRWMD gated entry using one of their ATVs, followed a trail along riverbank, then up the dry river bed by 4-wheel ATV. Mike Randall and I waded into the pool with large landing nets (the smallest net shown here) and also a two-brail seine. After a lot of chasing the fish around we managed to net them all. I was in the water to begin with, but then took photos while the younger guys chased the fish around and managed to capture them. That was not easy. Continue reading →

Where does southwest Waycross drain? 2025-11-23

According to the U.S. Geological Survey (USGS), the Suwannee River Basin starts in Waycross, Georgia, around a line south down Gibbs Street, east on Walker Road, south on Gilmore Street, south down Swamp Road, then east along Washington Drive.

Where does southwest Waycross drain? Through Lees Branch, into Middle Fork, Suwannee River

But what about the drainage canal you can see running southwest from Brunel Street across Gibbs Street?

Looks to me like that goes into the Suwannee River Basin.

People who live in Waycross, tell me if I got this right.

Map: SW from Brunel Street on the WWALS map of the Suwannee River Water Trail (SRWT).

North across Washington Street, there is a network of ditches that drains into Caney Branch into the Satilla River. Continue reading →

Road costs, well risks, taxpayers should decide –Lisa Sumner for Wayne Nash 2025-09-18

Update 2025-09-22: Water issues, Bradford Road subdividing –WWALS to Berrien Planning Commission 2025-09-18.

The information Lisa Sumner presented to the Greater Berrien Planning Commission Thursday on behalf of Wayne Nash is on the WWALS website. This was in opposition to the proposed subdivision on Bradford and Strawder Roads and Old Valdosta Road in Berrien County, Georgia, draining into Gin Branch Creek to the Withlacoochee River, through an aquifer recharge zone above the Floridan Aquifer.

Images of each page are below.

I’ve also enlarged Wayne Nash’s groundwater withdrawal permit, which shows “Well Design Pumping Capacity 600 gallons per minute.” Continue reading →

Need more river testing and more types of testing 2025-09-13

Update 2025-09-17: Clean Santa Fe River 2025-09-10, Filthy Sugar Creek, Dirty upstream Withlacoochee River 2025-09-11.

E. coli is the canary in the coal mine for other contaminants in waterways.

For years WWALS has been asking the state of Florida to test frequently in many places on all rivers, to very little response FDEP did do some testing for chemical and biological tracers, including DNA tests, after Valdosta’s huge December 2019 spill, but that petered out. While FDEP was doing that, those results helped identify another source of contamination that was not Valdosta.

WWALS did test the Withlacoochee River for PFAS forever chemicals and round some, although much less than many other rivers, and no higher below the outfall of Valdosta’s Withlacoochee Wastewater Treatment Plant or PCA’s package plant.

FDEP continued with quarterly tests for a while, and put at least its fecal bacteria results online. But it stopped doing that last year.

The 2020 GA-EPD Consent Order on Valdosta required bacterial testing of the Withlacoochee River over 40 river miles three times a week, for four years. Once those four years were up, Valdosta dropped back to two locaitons once a week.

USGS ceased financial support for nitrate and pH monitoring in eight Florida springs this year. It is not clear whether SRWMD picked up the slack.

We need more testing, not less.

Need more river testing, and more types of testing, DNA, PFAS, metals, etc., by FDEP and others

Treated wastewater still has PFAS and other contaminants, as Joe Squiteri of Lee, Florida, pointed out in the recent meeting of the Florida Rivers Task Force with the City of Valdosta. Continue reading →

Nitrate monitoring and mining on SRWMD land –Suwannee Riverkeeper to SRWMD Board 2025-07-08

Update 2025-07-21: PFAS in sewage effluent used to restore wetlands 2025-07-18.

I did get answers from the Suwannee River Water Management District (SRWMD) about nitrate testing for springs, but no response about the Chemours application to mine on SRWMD land in Bradford County in the Santa Fe River Basin, using mineral rights retained by Rayonier.

Nitrate monitoring of springs and Mining on SRWMD land, –Suwannee Riverkeeper to SRWMD Board 2025-07-08

Surprisingly, nobody showed up to speak at the recent SRWMD Board meeting in item 6. Public Comment. See SRWMD’s YouTube video at 15:28.

River water and groundwater interchange interacts with drinking water treatment 2025-03-26

We all drink with straws from the groundwater here in the U.S. southeast coastal plain.

River water and groundwater interchange interacts with drinking water treatment in Georgia and Florida

So surface water interchange with groundwater produces problems for city and county drinking water treatment, and for E. coli contamination of private water wells. Continue reading →
