Works in theory! Practice? That's something else
If you've been watching the news you've probably seen things about "rainwater being unsafe to drink" because of PFAS.
It's in the air, in the rain, and in the ground soil. A recent study found most rainwater on Earth now contains PFAS exceeding safe levels
Because it's in the water it affects animals:
And it also gets into the plants we eat:
So, how bad is it?
What can you do?
Although it's global, concentrations differ. I'm not sure anything can be done about the food you consume. ZeroWater claims they can filter out most of it. You can also send water samples to Water testing labs to see about local concentrations.
I don't know if it's hype or karma, but possibly you know more about the subject and can share?
What are PFAS?
Per- and polyfluoroalkyl substances, or PFAS, are a large group of human-made chemicals that have been used in industry and consumer products worldwide since the 1950s. Some have half-lives of a few years, some are extremely persistent lasting thousands of years and have been dubbed "forever chemicals".
It's in the air, in the rain, and in the ground soil. A recent study found most rainwater on Earth now contains PFAS exceeding safe levels
Because it's in the water it affects animals:
PFAS have been linked with adverse health effects in lab animals, including reproductive, developmental, liver, kidney and immunological effects. That raises concerns for humans, but because these chemicals are often found in bodies of water and elsewhere in the environment, it raises additional concerns for wildlife.
And it also gets into the plants we eat:
How can PFAS get into my garden plants?
PFAS can get into your garden plants if they are grown in soil or water containing PFAS. Usually, this happens when PFAScontaminated water is applied to the plants. When this happens, PFAS can be transferred from the water through the soil, where they may be taken up by the plant’s roots. ref
So, how bad is it?
A recent review from the U.S. Centers for Disease Control and Prevention (CDC) outlines a host of health effects associated with PFAS exposure, including cancer, liver damage, decreased fertility, and increased risk of asthma and thyroid disease. A June 20, 2018 ProPublica article noted that the CDC report recommends an exposure limit for one PFAS compound that is 10 times lower than the U.S. Environmental Protection Agency’s current limit. ref
