There's a lot of glass bottled water too, at least in Germany.

And plenty of aluminum cans of water as well, not to mention aluminum recycling is perhaps the most implemented recycling effort of any materials.

  Aluminum cans are typically lined with plastic.

    But it doesn't get released as easily. I've read a few weeks ago a thread on an ultralight backpacking forum where they were discussing cooking in beer can. They were pulling spec docs and Lab tests of how much plastic gets released if they cook in those cans. The results was that they release about 0.01% of FDA limit. So, according to ultralight backpackers on that forum, it should be safe.

  I'm not really sure how much glass or aluminum containers would matter to the fundamental point? The plant that purifies the water and puts it into the glass and aluminum containers almost certainly uses plastic or rubber tubing in its machinery. So you'd likely get some plastic particles transferred there as well. In the end, I'd be willing to bet that tap water has fewer micro plastics than water bottled in glass or aluminum. Problem, of course, is that your municipality likely uses some form of metal piping to get water to your tap. Which, depending on what all that is, could mean elevated lead levels etc. It's a tough problem.

    In a similar vein, does anyone know of any conclusive studies on the safety of PEX plumbing wrt releasing microplastics into our drinking water. My home is primarily PEX. It would be nice to know if I'm slowly poisoning my family.

(that's carbonated water in glass bottles)

  Since the parent comment says "Germany" I can say with confidence: We have both, so that qualifier is not true unless you specifically buy exactly carbonated water. It is true though that for whatever reason that I just cannot comprehend the majority of water sold in bottles in this country (Germany) is carbonated. nor can I understand why so much of it is sold - tap water is very good in most places. I know a water engineer at the local municipal water company and she too only drinks tap water. On the other hand so many Germans are extremely fixated on price, it's even more incomprehensible how irrational it is that my fellow Germans buy so much bottled water. I googled for "why do Germans buy bottled water instead of tap water" and unsurprisingly found that I'm not the first one to ask that question (first link of several, as an example, which sums it up pretty well: https://www.telegraph.co.uk/expat/expatlife/10661118/Why-do-the-baffling-Germans-bottle-out-of-drinking-tap-water.html https://www.telegraph.co.uk/expat/expatlife/10661118/Why-do-...). Oh and if somebody asks about "but what about chlorinated tap water" - that is less common in Germany. I cannot detect anything but "water" in the places I visit in various German states. Anyone concerned about such things can get a water filter, they are plentiful in supermarkets, mostly these types: https://i.pinimg.com/736x/31/ed/ff/31edff1af777601ac16d3329295d646b.jpg https://i.pinimg.com/736x/31/ed/ff/31edff1af777601ac16d33292... The website of my own municipal water company (of a large Bavarian city) says water is chlorinated only when it is absolutely necessary, and that if they do it they will also stop as soon as possible. So that is a temporary measure when something happened but not usually done. We (in Germany) do have a nitrate problem in a lot of places. We even got reprimanded by the EU about that only recently. The reason is agriculture, of course.

    > It is true though that for whatever reason that I just cannot comprehend the majority of water sold in bottles in this country (Germany) is carbonated. When I was a kid, my parents would only buy carbonated water. Still water was available from the tap. Today, I stopped buying even that, I can carbonate my water myself. As to why we buy so much bottled water: Marketing. Some waters have a distinct taste, but at least for me, it’s just a matter of getting used to a different tap water taste when moving.
