Background: DuPont spun off "The Chemours Company" as a separate entity in 2014, just as the states' environmental departments were starting to raise alarms about PFAs.  Cynics now say this was a move to limit DuPont's liability.

GenX is the one in the news currently.

High concentrations of fluorinated chemical GenX found in watershed
https://phys.org/news/2018-04-high-fluorinated-chemical-genx-watershed.html

"Industrial sites, airports, wastewater-treatment plants and fire-training areas upstream from the water treatment plant can all contribute to higher PFAS levels"

QuoteWhat wasn't low in Wilmington, however, were levels of GenX and other "emerging" PFAS chemicals. GenX and related compounds originated from a flurochemical manufacturing plant upstream from Wilmington owned by The Chemours Company.

GenX, the trade name for the ammonium form of perfluoro-2-propoxypropanoic acid (PFPrOPrA), is used to make polymers, such as the non-stick coating Teflon, food-wrapper coatings and other products.

DuPont seeks to toss Chemours environmental liabilities suit
https://apnews.com/a57467492681ee14604f27ff6552ed5b

"Chemours faces more than $200 million in costs to address environmental issues at a North Carolina manufacturing facility, 100 times more than DuPont's estimated $2 million maximum liability. Chemours also has said that potential environmental liabilities in New Jersey far exceed the $337 million cited by DuPont at the time of the spinoff.

In a consent order with the state of North Carolina, Chemours agreed last year to pay a $12 million penalty and $1 million for investigative costs, and to sharply reduce air emissions of a compound known as GenX. The company says the total cost of the consent order will exceed $200 million."

I thought it was mostly Teflon. Nope, wrong.

"PFAS are a class of about 15,000 chemicals often used to make products resistant to water, stains and heat. The chemicals are ubiquitous, and linked at low levels of exposure to cancer, thyroid disease, kidney dysfunction, birth defects, autoimmune disease and other serious health problems.

They are called "forever chemicals" because they do not naturally degrade.

The chemicals are thought to be contaminating drinking water for at least 200 million Americans, while watchdogs have identified thousands of industrial polluters. Similar widespread contamination persists throughout Europe."

That's not how we roll in the US. Lots of places with terrible tap water, often from agricultural pollution with the surprise to many people that rural water quality is often much, much worse than in the cities (SFO, NYC and LA long ago "stole" the water they needed from the pure sources in rural areas and then protected those watersheds).

Do Brita Filters Remove PFAS – Real World Testing Data
QuoteIf you're wondering do Brita filters remove PFAS from tap water, the answer is no. While activated carbon in a Brita pitcher can remove some of these contaminants from drinking water, it does not reduce their concentration to drinking water standards. Brita filters are not designed to treat PFAS and should NOT be used for this purpose.

QuoteExperts agree that a reverse osmosis system installed under your kitchen sink is the best option available to consumers. Duke tested these systems and found they removed 96% or more of these toxins, with no difference among brands.

They also waste a lot of water – only about 20% of the contaminated water ends being treated. The rest is dumped down the drain.

For a long time, Costco sold Hexclad pans which proudly said PFOAS-free. Which was true. But they also tried to say they were a new compound that was toxic free. It was only after I bought them that I found out that what they mean is they use a different PFAS that has not, at that time, been banned YET.

Recently I got a letter saying there was a class-action lawsuit against them.

Normally, I am against these things - very little restitution for the customers, lots of money for lawyers and often bogus accusations.

In this case, though, I think Hexclad is getting what they asked for with their marketing that was clearly intended to deceive.

It will be interesting to see the results (I am not part of the class because I couldn't find proof of purchase, which is sort of stupid since they got my name from Costco as someone who purchased, but there it is).

Supplement could help remove 'forever chemicals' from the body
https://www.futurity.org/fiber-supplement-forever-chemicals-3289482/

QuoteSchlezinger wanted to reduce her cholesterol, but didn't want to take a drug, so she started researching dietary interventions and found that gel-forming dietary fibers might help. One such fiber is cholestyramine, which, when taken with food, binds to bile acid and leaves the body with it after digestion. The body then has to replace the bile acid lost, and draws cholesterol from the blood to do so, reducing cholesterol levels.

Schlezinger realized that PFAS, like bile acids, are surfactants, with a neutral end and a charged end, which is what makes the acids stick to the fibers. She wondered if gel-forming fibers could help us expel PFAS just as they do with bile acids.
Title: Re: PFAS
Post by: rcjordan on August 21, 2025, 02:09:49 AM
>cholestyramine

My wife was on it for 2 months. It's loose, large-ish granules of resin and is very inert ...doesn't mix with anything well.  Tough med to have to take every day.  I happened to be experimenting with 'overnight oatmeal' with 1 tbsp of chia seeds for a breakfast cereal.  She tried it and it completely replaced cholestyramine with the same good results. If she misses a day or two of chia seeds the bile acid starts kicking up right away.

Quotehe research shows that mothers receiving water from wells that are "downstream" (in groundwater terms) of PFAS-contaminated sites, as opposed to comparable mothers receiving water from "upstream" wells, had higher first-year infant mortality, more preterm births (including more births before even 28 weeks), and more births with infants weighing less than 5.5 pounds (including more births with weights less than even 2.2 pounds). These findings build on earlier laboratory and public health research but offer new evidence from real-world exposure across a large population.

Extrapolating to the contiguous US, PFAS contamination imposes costs of at least $8 billion on the babies born each year, which encompasses medical care, long-term health impacts and reduced lifetime earnings. The results indicate that the potential health benefits of PFAS cleanup and regulation may be substantial.
