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 →

Chemours to blame for flooding rural Santa Fe River Basin? –Grist 2025-09-04

Update 2025-09-05: Clean Alapaha and Withlacoochee Rivers 2025-09-04.

What is overflowing in that floodwater from those five Chemours mines on Trail Ridge at the top of the Santa Fe River Basin?

“If I lived near Chemours, I’d be paranoid too,” said John Quarterman, who serves as the Suwannee Riverkeeper, a staff position for an organization of the same name that advocates for conservation of the numerous watersheds within the Suwannee River Basin. “Some of the stuff they’re paranoid about is probably actually happening, but it’s hard to document which of it is and which of it isn’t.”

Until the Florida Department of Environmental Protection takes frequent measurements up and down the state’s rivers, Quarterman said, it will be difficult to pin down the impact of Chemours’ activities. And without such studies, he said, it’s difficult to identify bad actors — let alone hold them accountable.

WWALS has a volunteer water quality monitoring program, and two recently-trained testers may start testing in the Santa Fe River Basin soon.

Is Chemours to blame for flooding rural Santa Fe River Basin? –Grist 2025-09-04

Sachi Kitajima Mulkey, Ayurella Horn-Muller, Grist, September 4, 2025, Waterlogged and contaminated: In rural Florida, locals suspect a mining company is to blame for their flooding troubles: Residents are trying to connect the dots between hurricanes, high radium levels, and a mineral mining giant next door.

The storm had passed, but the water kept rising. In September 2017, Hurricane Irma slammed into Florida, causing tides to surge and dumping about a foot of water across much of the state. A few days later, Jane Blais stood on a bridge with her neighbors near her High Springs ranch, watching the Santa Fe River below swell higher and higher.

“We had zero notice,” Blais said, Continue reading →

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

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.

SRWMD & SJRWMD aquifer recharge project update @ SRWMD 2025-07-08, What about PFAS? and limits on water withdrawals?

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.

PFAS in sewage effluent used to restore wetlands, Maybe into Nutrien Phosphate Mine wetlands on Swift Creek

See the Suwannee River Water Management District (SRWMD) YouTube video of its July 8, 2025, Governing Board meeting:

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 →

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.

Water too low for jon boat outboard, Withlacoochee River, Chainsaw Cleanup 2024-10-26

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.

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.
