Another way I'm potecting my family is voting.
We need elected officials who prioritize people over profits at the federal, state, and local level. We're turning the wrong way on dealing with a dangerous contamination in our environment. x/
TL;DR: get a water filter

Studies found up to 84% of dietary PFAS coming from seafood, but many of these are in countries with lower enviornmental pollution. The benefits of eating seafood outwiegh the risk from PFAS, but lower consumption of shellfish and tuna in favor of things like salmon helps.

Ironically, stain resistant cotton has more PFAS than polyester. (Regular cotton has less.) I'm choosing a PU polyester rain suit for the kids over a goretex-type one. Sorry, sweaty babies.

Avoiding clothes with PFAS: I live in the Northwest and we need a lot of waterproof clothing. While you’re not likely to get significant exposure from your hiking boots, it's still adding more to the environment. We wear Keens, and I like Nikwax for waterproofing.

FDA has a list of 35 PFAS ingredients that companies add to cosmetics. I avoid these. Rulemaking was underway to remove them from the market, but that is now stalled. Many are present in makeup, haircare, and sunscreen.

Regular handwashing reduces PFAS concentrations on the hands. For infants and toddlers, up to 40% of their PFAS exposure if through hand-to-mouth dust exposure. Along with vacuuming, make sure babies and toddlers are washing their hands before eating.

All drinking and cooking water goes through the filter. I’d love a house filter, but that’s not an option at this time.
Dust and vacuum regularly, preferably with a HEPA filter. In adults, inhalation and ingestion of PFAS dust makes up 10-15% of exposure.

The current administration makes the future of PFAS removal more concerning, as funding constraints on states and municipal budgets are delaying infrastructure projects. Testing and research funding has also been cut.

You can also ask your local water utility what they're doing about PFAS, and ask your state representatives to address the issue. Many utilities are working on filtration systems to remove PFAS from the water, but those are often a couple years away.

Filter your water. Now. Please. I like ZeroWater because it's economical and effective, but anything helps. A Brita gets about 80%. A reverse osmosis system is great, but expensive. The lowest rated filters remove ~50% of PFAS, but that's still 50% less exposure from water.

For all the "crunchy" concerns about our food, most claims about hormone disruption and immune function center around non-specific and unproven vibes, usually because they want to sell you something to "detox". But we have evidence for the toxicity of PFAS, and a solution:

Even low-level PFAS exposure is linked to immunotoxicity in children. PFAS in pregnant women can increase blood pressure and result in low birth weight infants which leads to developmental disorders. PFAS can disrupt fertility, cause cancer, and disrupt hormone function.

Yes, PFAS is now ubiquitous in the environment and our food supply, and it’s still used in many products.
But, dose makes the poison, and the largest dose is coming from your drinking water.

The EPA found that most PFAS exposure was in drinking water (~50-70% of total),
followed by diet (~40%),
inhalation and ingestion of dust (~10-15%),
and dermal exposure (~2-5%).
Local contamination can significantly increase your overall exposure from drinking water.

PFAS degrades in the environment over time and the degraded form is easier for the body to absorb. A generation of neutral PFAS in our environment has now become more persistent and toxic ionic PFAS.

A difficulty in public health is getting people to understand how additional resources and knowledge are improving outcomes, but you never see how fully because there's always something else. It’s like new holes keep opening up in the ship hull.

PFAS is found in food, water, clothing, cookware, cosmetics. And dermal exposure and inhalation are significant, it's not just ingestion.
The message is: you're getting it from other sources, so your water contamination isn't that big of a deal. This is dangerously misleading.

To be clear: We don’t have a fertility collapse happening right now. We had the first generation knowingly picking worse for their children (see Greenspan Commission), "higher taxes for everybody— after me" or insolvency.
If there’s a crisis, it’s one of selfishness, not birth rates.
