Filter your water if you live anywhere near an airport or military base anywhere, it's not just California. In Satellite Beach, Florida, the contamination from Patrick AFB was discovered after a group of Satellite Beach High alumni realized they all developed cancer around the same time and decided to start digging. [ https://pfasproject.com/2018/08/08/satellite-beach-florida-f... ] They dumped everything in a trench…

I'd also just filter/test your water everywhere :( I'm in Chicago, and my daughter and I decided to test some public water fountains near the city zoo for lead. Thought it would be an interesting way to expose her to more science. I also had a suspicion of water fountains I've been finding now "capped" and no longer working. One of the fountains we tested with a home test kit from Home Depot came up positive for lead…

FWIW I witnessed a tweaker perched on top of one those public water fountains on the LFT, washing his bottom. I'd need to be nearly dead from dehydration to drink from one at this point.

That might kill the algae but likely won't destroy most of the toxins in the water that the algae produce. https://en.wikipedia.org/wiki/Cyanotoxin

Do the toxins get carried on along with distillation as well? That's ridiculously energy-intensive and you'd probably have to re-mineralise it before storage or consumption to be on the safe side. Cooking might actually be the worst issue here, low-mineralisation cooking water would leech minerals out, leading to lower nutrient intake (unless yo keep the cooking water for drinking).

Distillation would make the water safe, reverse osmosis should also work. You don't need to remineralize water, you get minerals from food not from tap/mineral water and you don't need to worry about leaching your pots and pans.

The same problem exists with PFC foam used at military and civilian airports in Germany (and probably around the world): https://www.tagesschau.de/investigativ/report-muenchen/bunde... (in German)

It's a worldwide problem. I would safely guess just about every airfield in America is dealing with this issue, even if there hasn't been a specific article written about it yet.

There was a cancer cluster at the CFA Fiskville training facility in Victoria, AUS.

My uncle was station chief there for many years and recently died of complications after surgery to remove tumors. He was suffering back pain for a while and was diagnosed with spinal cancer. No one in the family was aware there was a cluster reported.

Yeah. I’ve been running 10 miles now at a time and I still refuse to use those things. I’m thankful the zoo has vending machine that that Apple Pay :)

EPA Superfund sites --- ok I did not know about this until this thread... omg!

I just recently found out the Shoreline Park in Mountain View used to be a landfill for most of bay area and SF. Today it is open to enjoy like it's some natural bird sanctuary.. yet there are pipes underground extracting methane 24x7 and I think I found a methane release valve last weekend right next to a jogging path... Can anyone confirm plz? => https://www.youtube.com/watch?v=kq3CnXU5OtU

No, you can't test for PFAS with consumer kit, it's dangerous at 70 parts-per-trillion levels and is tricky to handle without contamination. The test itself is expensive, too. I'm in the part of Rockford, Michigan contaminated by Wolverine/Hush Puppies/Caterpillar shoe leather tannery scraps, and they've paid Rose & Westra GZA to send techs to my house every 6 months. A friend just outside the supposedly affected are…

"In my case, however, a pair of 48"x10" granular activated carbon filters ..." Are those backwashing filters with a head unit that contains a pump ? What level (micron) of filtration does just that unit achieve ? Just curious ...

No pump, just passthrough. I don't believe they provide any filtration, just reaction mass/catalyst. I can take a picture tomorrow if you're curious.

Those sound like big filters. Where are they installed, and how often do you replace? Or is that just pitcher volume?

They're in my unfinished basement. Culligan (on Wolverine's dime) handles the service, had one replacement in almost 2 years. They just disconnect,install refurbished units, and bring my old ones back to contain the chemical waste and repack with fresh carbon.

Methane outgassing is a known issue within the Shoreline Amphitheatre itself! It's built on a former dump.

During the earliest events there in the 1980s, concertgoers seated on the lawn set it afire when trying to smoke!

(And, yes, it's misnamed. It's a theatre, not an amphitheatre.)

There are EPA Superfund sites all over the valley. One of the worst was across the street from the Ice Center and Spartan Stadium.

I pay nothing (monthly). But I am rural, and have my own well and septic system. Which cost, if I remember right, $5000 decades ago when built. Which amortizes to maybe $20/month.

Do you test your water for impurities and chemicals?

Sure. But the water is from 111' down, and got there 10,000 years ago. So probably not an issue.
