PFAS fixes to wastewater treatment could keep drug residue out of rivers 2021-08-11

The PFAS problem may cause wastewater treatment that cleans up another bad problem: pharmaceuticals.

Tara Lohan, The Revelator (Center for Biological Diversity), August 11, 2021, What Happens to Wildlife Swimming in a Sea of Our Drug Residues?

Wastewater exposes plants and wildlife to hundreds of chemical compounds. Researchers are learning about potential side effects and solutions.

Effects range from obvious physical defects to behavior change. For example, bold crawfish are not safe crawfish.

PFAS in sewage sludge as fertilizer 2023-03-30

Human sewage sludge used as fertilizer is a huge problem in Florida, causing algae blooms when it runs off into waterways. In Georgia, distributing sewage sludge as fertilizer may not be as common, but some Land Application Sites (LAS) rent their spray fields for growing hay or other crops. Plus such waste may also carry cancer-causing forever chemicals: PFAS.

Jenny Staletovich, WLRN 91.3 FM, June 2, 2021, State Tightens Rules For Sewage Sludge Used As Fertilizer But Leaves A Loophole In Place,

As damaging algae blooms continue to afflict Florida, the state is taking steps to crack down on and track pollution from biosolids, the waste from sewage plants loaded with nutrients that can fuel blooms.

But the new rules, conservationists warn, continue to ignore a loophole for about 40% of the state’s waste.

PFAS forever chemicals are in everything –WUFT 2023-02-14

“This stuff is in everything,” said Suwannee Riverkeeper John Quarterman.

In the Withlacoochee River, in fish in the Alapaha River, maybe in your house. Georgia, Florida, and U.S. EPA should do something about it.

Fernando Figueroa, WUFT, February 14, 2023, Community members speak up about new “forever chemicals” study

A new study by the Environmental Working Group, an activist group focused on research, revealed that eating a single freshwater fish is equal to drinking water with high PFAS levels for a month.

Per- and polyfluoroalkyl substances, also known as PFAS or “forever chemicals,” are Continue reading

PFAS in fish in Alapaha River 2023-01-17

Largemouth bass caught in the Alapaha River at Statenville Boat Ramp had high concentrations of PFAS forever chemicals.

EWG summarizes the risk:

Eating just one PFAS-contaminated freshwater fish per month could be the equivalent of drinking a glass of water with very high levels of PFOS or other forever chemicals.

What does this map show?

From coast to coast, and in almost every state in the U.S., high levels of the “forever chemicals” known as PFAS contaminate freshwater fish. The potential harm is not limited to fish, but the pollution poses health risks to communities that catch and eat the fish.

This map, based on data from the Environmental Protection Agency, confirms the detection of PFAS at alarming levels Continue reading

Forever chemical residue can even be in your house lot 2022-11-27

That house you bought may come with forever chemicals, per- and polyfluoroalkyl substances (PFAS), which can harm human (and wildlife) health in many ways.

Florida permits shipping sewage sludge from south Florida to north Florida for agricultural fertilizer. It’s not clear how prevalent the same practice is in Georgia. But from fields it can wash into waterways, and subdivisions may be built on fields that had sludge applied.

At the end of Joy Road in Fairfield, a steep dead-end road climbs a hillside to a scattering of homes with distant mountain views and some of the higher concentrations of per- and polyfluoroalkyl substances (PFAS) the state has found to date in groundwater. The neighbors here live under what one resident, Nathan Saunders, called the “cloud of an unknown future,” fearing how PFAS exposure may erode their health.

PFAS contamination may be much more widespread than previously known 2022-10-12

A new model indicates sources of PFAS “forever chemicals” may be much more widespread than usually thought.

Abstract

While research and regulatory attention to per- and polyfluoroalkyl substances (PFAS) has increased exponentially in recent years, data are uneven and incomplete about the scale, scope, and severity of PFAS releases and resulting contamination in the United States. This paper argues that in the absence of high-quality testing data, PFAS contamination can be presumed around three types of facilities: (1) fluorinated aqueous film-forming foam (AFFF) discharge sites, (2) certain industrial facilities, and (3) sites related to PFAS-containing waste. While data are incomplete on all three types of presumptive PFAS contamination sites, we integrate available geocoded, nationwide data sets into a single map of presumptive contamination sites in the United States, identifying 57,412 sites of presumptive PFAS contamination: 49,145 industrial facilities, 4,255 wastewater treatment plants, 3,493 current or former military sites, and 519 major airports. This conceptual approach allows governments, industries, and communities to rapidly and systematically identify potential exposure sources.

Forever chemicals contaminate Withlacoochee River in Georgia and Florida 2022-10-18

Update 2022-12-24: PFAS contamination may be much more widespread than previously known 2022-10-12.

Hahira, GA, October 18, 2022 — A first-of-its kind study by Waterkeeper Alliance found 83% of the waters tested across the country, and 100% of tested waterways in Georgia and Florida, were contaminated by dangerous PFAS chemicals.

“The PFAS levels we found in the Withlacoochee River were lower than most sites in the U.S., but there should not have been any,” said Suwannee Riverkeeper John S. Quarterman. “WWALS is working on ways to do more tests to narrow down likely sources and to see how rain events affect the results.”

Figure 11: bigger circles indicate more contamination

The good news: PFAS levels in four test sites on the Withlacoochee River were among the lowest in the study. Still, there are currently no universal, science-based limits on the various PFAS chemicals and their presence is cause for further investigation. For many PFAS chemicals, the EPA has not set a health advisory limit that would give the public a baseline to determine what amount of PFAS is unhealthy in drinking water. In most cases, the EPA is not doing adequate monitoring for these chemicals, which is why these findings are so relevant and important.

The bad news: Continue reading

Forever chemicals in rainwater everywhere 2022-08-02

U.S. EPA may get around to mandatory limits for drinking water later this year.

Georgia and Florida have no mandatory limits for these per- and polyfluoroalkyl substances (PFAS). Georgia EPD is monitoring drinking water (mostly clean) and some surface water (in north Georgia, with some bad results). FDEP “ continues its efforts to investigate and understand PFAS in the environment and the ecological and human health risks associated with PFAS contamination.

My backup drinking water is rainwater collection. Probably the charcoal filters I use remove PFOAS, although Continue reading

PFAS testing, Withlacoochee River, Georgia and Florida 2022-06-30

Update 2022-10-18: Forever chemicals contaminate Withlacoochee River in Georgia and Florida 2022-10-18.

Update 2022-07-03: Withlacoochee River OK water quality except GA 133 2022-07-02.

WWALS Science Committee Chair Dr. Tom Potter and I took PFAS samples at four locations on the Withlacoochee River Thursday.

We shipped the samples to Cyclopure, a company with which Waterkeeper Alliance got a deal for test kits for all U.S. Waterkeepers.

We picked Thursday because it was after big rains Wednesday, reported in some places nearby as up to four inches. So if any of those forever chemicals were washing off of fields fertilized with biosolids, or coming out of Valdosta’s Withlacoochee Wastewater Treatment Plant, or just left over from Moody Air Force Base’s spills it documented in 2016, maybe we will detect them.
