SRWMD & SJRWMD aquifer recharge project update @ SRWMD 2025-07-08

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

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

Update 2025-08-31: SRWMD purchased Rayonier tract with mineral rights leased to Chemours for TiO2 mining –SRWMD to Carol Mosley 2025-07-11.

A billion dollars to run Jacksonville and JEA treated wastewater through wetlands in the Suwannee River Basin and into the Floridan Aquifer: this proposal was presented to the SRWMD Board this month.

Nevermind that sewage effluent carries PFAS forever chemicals into wetlands. After contaminating all the wetland wildlife, PFAS would continue into the Florida Aquifer, from which we all drink.

A SRWMD Board member pointed out that desalination of seawater would cost less. Another pointed out that Jacksonville would just suck the water back out of the aquifer. More on board comments below.

Instead, how about Jacksonville and JEA treat their effluent to drinking water standards and reuse it for themselves? The money they save from pumping it to any of those recharge areas would be enormous. That would use less groundwater, so there would be less need for recharge.

The excuse for this project is increasing population needing more water. Continue reading →

PFAS in sewage effluent used to restore wetlands 2025-07-18

Update 2025-07-25: SRWMD & SJRWMD aquifer recharge project update @ SRWMD 2025-07-08.

It’s well-established that ordinary wastewater treatment does not remove PFAS forever chemicals. Yet two Florida Water Management Districts want to use treated wastewater from Jacksonville into wetlands to “restore” levels and flows in the Santa Fe River and many springs in the Suwannee Basin.

It’s hard to tell from that project’s map, but it sure looks like one of the target wetlands is at the top of Swift Creek in the Nutrien Phosphate Mine in Hamlton County. Continue reading →

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.

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 →

U.S. EPA recognizes sewage sludge on farmland among human health risks of PFOA and PFOS forever chemicals 2025-01-14

WWALS Science Committee Chair Dr. Tom Potter notes, “Finally EPA has recognized the risks of sludge application to farmland.”

Sewage sludge as fertlizer is a widespread problem in Florida.
https://wwals.net/?p=61560

These forever chemicals as in our rivers in Georgia and Florida. They collect in fish, including in the Alapaha River.

Waterkeeper Alliance encourages Waterkeeper groups to participate in the public comment period, which must be received on or before March 17. Individuals and other groups can also comment.

Retrieving PFAS samplers, Mud Swamp Creek 2024-10-29, Withlacoochee River 2024-11-23

Update 2024-11-30: Bad Sugar Creek, clean Withlacoochee River 2024-11-26.

Hurricane Helene destroyed three out of four PFAS samplers, and kept us from retrieving the fourth until long after time.

Hurricane Helene demolished PFAS samplers, Withlacoochee River 2024-11-23, Mud Swamp Creek 2024-10-29

Back on September 14 and 15 we deployed four PFAS samplers, upstream and downstream from two wastewater treatment plants, on the Withlacoochee River and on Mud Swamp Creek.

These are a new design that you leave in the flowing water for 28 days thereabouts, then retrieve, and effectively they were taking a sample a day.

But then came Hurricane Helene.

Thanks to Gee Edwards and Phil Royce for helping on the Withlacoochee River Saturday, after the chainsaw cleanup. Especially thanks to Phil for the tow back when the 9.9 hp outboard quit. We’ll investigate what is its problem this time.

We put the upstream sampler slightly up from Valdosta’s Withlacoochee Wastewater Treatment Plant (WWTP) Outfall.

That was the only one we actually could retrieve. Continue reading →

Pictures: Withlacoochee River Chainsaw Cleanup 2024-10-26

The water level was not too low on the Little River, but it was too low on the Withlacoochee River for the WWALS jon boat with outboard. So, there was no chainsawing.

We’ve been waiting for the Withlacoochee River to get down to a level where we can do a walking chainsaw cleanup. With no rain in sight, it will be plenty low next Saturday, so that will be the time.

Thanks to TJ Johnson for driving an hour from Live Oak to get there with chainsaws to lead this expedition, and for helping haul the jon boat back upstream on muscle and trolling motor batteries after the outboard did not restart after Trashy Shoals. Continue reading →

Upstream Withlacoochee River from Troupville Chainsaw Cleanup after Hurricane Helene 2024-10-26

Update 2024-10-27: Pictures.

Kayaks and canoes and jon boats are invited to join the WWALS jon boat with 9.9hp outboard seeking deadfalls to chainsaw and trash to collect. After Hurricane Helene, there are probably new ones. We will go as far up as we can and have time for with sawing, maybe to the GA 133 Bridge, the I-75 Bridge, or even Sugar Creek.

Nobody has to use a saw of any kind. You can collect trash, photograph, video, pull limbs out of the way, or just paddle.

First we will jaunt downstream past the cleaned-water Outflow of Valdosta’s Withlacoochee Wastewater Treatment Plant and Spring Branch to pick up a couple of PFAS water sample collection devices we planted on September 14. If they’re still there after the hurricane.

If you’re paddling, you can just turn left at the Little River Confluence and go on up the Withlacoochee River.

When: Gather 9 AM, launch 9:30 AM, end 2 PM, Saturday, October 26, 2024

Put In: Troupville Boat Ramp, 19664 Valdosta Hwy, Valdosta, GA 31602. I-75 exit 18, west on GA 133 (St. Augustine Road) away from the Valdosta Mall, at the traffic light for Val Tech Road, turn left down to the boat ramp, in Lowndes County.

PFAS Sampling Deployment, Withlacoochee River 2024-09-14, Mud Swamp Creek 2024-09-15

Update 2024-11-27: Retrieving PFAS samplers, Withlacoochee River 2024-11-23.

This weekend we deployed four PFAS samplers, upstream and downstream from two wastewater treatment plants, on the Withlacoochee River and on Mud Swamp Creek.

These are a new design that you leave in the flowing water for 28 days thereabouts, then retrieve, and effectively they’ve been taking a sample a day.

If you encounter them, please leave them be.

Ask for U.S. House co-sponsors for PFAS amendments to the National Defense Authorization Act 2024-06-07

You can help ask your members of Congress to protect military servicemembers, the surrounding community, agriculture, industry, and wildlife.

Numerous military bases in recent years have reported contamination of waterways and groundwater by PFAS, the so-called forever chemicals that do not degrade over time, and can cause a variety of diseases.

[Map: military sites with known or suspected PFAS discharges --EWG]
Map: military sites with known or suspected PFAS discharges –EWG

Right now is an opportunity to get a couple of amendments into the National Defense Authorization Act (NDAA) to require the Department of Defense to tell everyone about PFAS contamination, to test to see how far it has spread, including private wells, and to provide alternate water supplies if necessary.

That PFAS work will also bring federal dollars to the districts.

You can sign on to a request letter here:

Or write your own, or call or meet with your Representative.

Affected bases include: Continue reading →

PFAS in the Santa Fe River Basin in Florida

Some people are interested in whether PFAS from titanium dioxide (TiO2) mines or other sources is getting into the New or Santa Fe Rivers in Florida.

For example, the new Chemours Trail Ridge South Mine southeast of Starke, Florida, appears to drain into Double Run Creek, which runs into the Santa Fe River.

[PFAS in Santa Fe River from TiO2 Mines?]

Detail from WWALS map of the Suwannee River Water Trail.

We don’t know about those rivers yet, because nobody has tested them. We do have a few datapoints for a few city drinking water systems, and they’re all clean, although Newberry, just outside the Basin, is not.

No doubt it is possible to find that data in FDEP’s Oculus Document Management System, in the same way it is possible to win a jackpot in Las Vegas. If you already know about six very specific parameters, sure, Oculus will find it. Continue reading →
