A recent study (made it to HN) used a novel sensor to count microplastics in bottled water. The numbers were 10x higher than expected, but the real surprise was that 50% were shed from the plant filtration system.
I’m guessing RO is similarly bad (the membrane is made from one of the plastics in question).
