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.

That model was published while Waterkeeper Alliance was working up the report on the nationwide PFAS sampling, including the Suwannee Riverkeeper results on the Withlacoochee River in Georgia and Florida.

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.”

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

Tank fire shortage of toxic PFAS firefighting foam at Houston Ship Channel

This “special foam”: yes, it’s probably the same toxic PFAS chemicals spilled at the Ocala, FL firefighting school and at Moody AFB near Valdosta, GA. Massive ammounts of it were used at the ITC tank farm, with its own docks on Buffalo Bayou into Burnet Bay, leading to Galveston and the Gulf. Then a massive storm hit, closing that Houston Ship Channel and stopping cleanup operations. It’s so bad even the state of Texas and Harris County are suing ITC. Meanwhile, whoever heard of a solar farm fire?

Firefighters at Houston Chemical Disaster Scrambled for Foam, by Joe Carroll and Kevin Crowley, Bloomberg, March 29, 2019, 12:10 PM EDT Updated on March 29, 2019, 3:18 PM EDT,

Firefighters confronted with the worst Gulf Coast industrial disaster in 14 years had to call on outside sources to augment their supply of the special foam required to extinguish chemical blazes.

Intercontinental Terminal Co. confirmed it appealed to other companies for foam during the fire Continue reading

Georgia legislature passed a firefighting foam regulation bill 2019-03-28

Both houses of the Georgia General Assembly have passed a bill to regulate PFAS fluorinated firefighting chemicals, such as spilled at Moody Air Force Base and the other two Georgia AF bases. If the governor signs it, this bill will become law.

Passed both House and Senate, HB 458

The bill is rather limited in scope, basically only Continue reading

EPA kicks PFAS regulation a year down the road

Yesterday’s EPA PFAS plan does nothing except to study for a year or more what has already been studied. Where are the limits on amounts of these firefighting chemicals in water that would enable EPA or GA-EPD to test private wells, for example for the PFAS that got into groundwater from Moody Air Force Base’s Wastewater Treatment Plant, causing Moody’s report to say be careful eating fish caught in Beatty Branch or Cat Creek, upstream from the Withlacoochee River? Where are the funds and methods to remediate the problem and to stop it getting worse?
