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.

[Worldwide, graph]
Worldwide, graph

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.

Estrogens and PFAS from cattle manure into rivers

We already knew E. coli was washing into the Withlacoochee (and other) rivers from cattle manure; that is one of the main reasons for our WWALS volunteer water quality testing program.

We also need to worry about estrogens and the PFAS forever chemicals, not only washing off of fields with cow-applied cattle manure, but also off of fields where manure has been applied as fertilizer.

Thanks to WWALS Science Chair Tom Potter for finding these articles.

Various forms of artificial estrogen are known to damage fish and other wildlife, and can affect humans. Lactating dairy cows produce natural estrogen. I have asked the Florida Department of Environmental Protection (FDEP) to add estrogen tests to its batter of DNA markers and chemical tracers. So far no response.

Report chemical constituents for forensic PFAS source identification –WWALS to U.S. EPA 2021-09-27

We requested much more labeling of chemical constituents of PFAS “forever chemicals”, to enable tracking PFAS contamination to its sources, when U.S. EPA held a public comment period about a PFAS rule.

The Atlanta Journal-Constitution brought this problem to our attention back in 2018, due to PFAS contamination from all three Air Force bases in Georgia, plus it turns out the Florida Fire College in Ocala. There are probably many more sources, including biosolids dried out from human wastes and used as fertilizer.

Jesup deja vu times two: DuPont, Chemours, Twin Pines, titanium mining, Folkston, Starke

Does this sound familiar? “DuPont planned to separate the mineral sands from the rest and then truck that to its facility in Starke for final processing.”

Multiple organizations also said Twin Pines Minerals (TPM) told them TPM planned to haul ore to Starke to process from TPM’s proposed mine in Charlton County, Georgia, but this was DuPont, in 2014, in Wayne County. And Chemours, starting about 2016, also in Wayne County.

Moody dummy bomb report from Suwannee Springs –WCTV 2019-07-02

Will Moody AFB find the dummy bombs an A-10C Warthog dropped near Suwannee Springs the other day?

Moody AFB and Lowndes County on U.S. PFAS contamination map 2019-05-06

Should we be proud? Lowndes County and Moody Air Force Base again made it onto a national map of PFAS firefighting foam contamination, as did the Florida State Fire College, Ocala Florida.
