Rainwater Is No Longer Safe to Drink

Bad News for Earth: Rainwater Is No Longer Safe to Drink Thanks to Plastic

Remember when you were a kid, and it was fun to tip your head back during a rainstorm and open your mouth to drink the drops? You shouldn’t do that anymore. That’s because you’ll be ingesting too many particles of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), the hazardous chemicals that leach from the ultra-durable plastics we’ve created for about the past 120 years.

Earth is officially past its safe zone for plastic contamination. The PFAS “boundary has been exceeded,” according to a study published August 2 in the journal Environmental Science and Technology. PFAS are known to be hazardous to both the environment and human health. At this point, these “forever chemicals” are all over the globe and have seeded the atmosphere. Most importantly, they don’t break down in the environment.

“Based on the latest U.S. guidelines for PFOA in drinking water, rainwater everywhere would be judged unsafe to drink. Although in the industrial world we don’t often drink rainwater, many people around the world expect it to be safe to drink and it supplies many of our drinking water sources,” Ian Cousins, a professor at Stockholm University’s Department of Environmental Science, and the lead author of the study, says in a news release.

The original study titled Outside the Safe Operating Space of a New Planetary Boundary for Per- and Polyfluoroalkyl Substances (PFAS) is here..

Still gonna ...

Maybe you can dig up about all the mask pollution next from the wasted past couple years. I bet its worse news and more topical.

Maybe you can dig up …

a study on the deleterious inability to recognize a difference between practical research, opinion, conspiracy, and wedge issues.

I saw this article about the rainwater. One of the saddest things I've ever read. I wonder if our catchment filters help. I imagine UV is worthless for this.
Certainty will be the death of us.

This article says they can be filtered but doesn’t go into detail whether that’s for homeowners, or municipal systems:

Currently, PFAS can be filtered out of water but then need to be destroyed somehow. If the chemicals are dumped in a landfill or tossed in an incinerator, they can still pollute the environment.

According to EPA , filters can remove PFAs. Since I already use charcoal filters I guess I'm okay. Just have to start incinerating my old filters.

I see no reason that RO would not remove PFAS. I send the RO brine back to my catchment tank so I would still get exposure through bathing and laundry. Not saying it is not bad news. It is. As far as filtering goes though, RO should do the job for drinking and cooking. Also I wonder what our exposure is here in Hawaii. It has to be somewhat less than mainland China for example.

Yea, thanks China, maybe we should all stop buying plastic junks. And educate our friends and family whose only news and views of the world come from mainstream media.

Great place to start.

China, or mainstream media?

"Oh, but that's from 5 years ago." Sure.

Can someone clarify if rainwater in Puna is no longer safe to drink? The subject of this thread certainly suggests that's the case.
