Other posters in this thread who know more about these things than I do have suggested that the filters used in catchment systems should eliminate the plastic. What's not clear about all of this? What we all need to "do" is eliminate single-use plastic.
And in that article, it says:
"Nevertheless, based on the four PFAAs considered here, it is concluded that in many areas inhabited by humans the planetary boundary for PFAS has been exceeded based on the levels in rainwater, surface water and soil, with all of these media being widely contaminated above recently proposed guideline levels."
Now, I just did skim the article, but I don't think "many" equates to everywhere, which is why I'm asking if rainwater here is safe to drink. for instance, if the water here tests the same as those in Antarctica or the Tibetan Plateau, then I would agree there's a risk but those places only exceed the most stringent guidelines.
In other words, I'm trying to make this Hawaii-related which certainly wasn't how it started. And I agree eliminating single-use plastic is something that's needed, but Hawaii doing that on its own won't change much.
