Shoot I can't remember where I read that offhand. I did find this paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6449537/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6449537/ In figure 1, untreated tap water ranked higher than bottled water in plastic particle count per unit volume. They conclude that standardization of micro plastic analysis and more studies are needed. It's said that we should never attribute to malice that which is adequately explained by stupidity, but, the plastics lobby has so much power that suggesting they had nothing to do with our ignorance of this issue is.. laughable at best.
