HDPE Nalgene bottles probably leach PFAS: https://www.reddit.com/r/Nalgene/comments/wqdgbi/are_nalgenes_pfas_free/ https://www.reddit.com/r/Nalgene/comments/wqdgbi/are_nalgene... Glass or stainless steel would be a better choice (especially for storage).

Whats my risk of exposure to lead from improperly made glass or stainless steel?

  Stainless steel could easily contain quite some ppm of lead. Metals are frequently recycled, and hard to separate. Glass could also contain lead in contaminants - but actual metallic lead won't end up in the finished product - but lead oxides might well. Having said that... There are probably many devices in your house or supply chain which deliberately contain lead in double digit percentages. Worry about those before worrying about contamination.

Worry about those before worrying about contamination. I cycled pulverized lead paint around my alveoli as a kid doing construction and used to bite lead fishing weights when I was very young to make sure they stayed on the line. Thankfully it is now stored in my skeletal system for future use by my nervous system.

My old bottle with this same filter was glass, but it was very heavy and it also ended up shattering when I was climbing a mountain and lost my balance and had to toss it onto a nearby ledge. And the filter itself filters a lot of pfas and other microcontaminants. "That's why we've taken a layered approach, incorporating a variety of high-performance filter media into one powerful filter. Crafted and rigorously tested in the United States, this multi-layered filter is engineered to effectively target both tap water pollutants such as chlorine, microplastics, lead, PFAS, and more, as well as outdoor water contaminants like bacteria, viruses, and microbial cysts like cryptosporidium and giardia." And the lid and straw itself is also made of plastic. Life is hard and something is better than nothing.

Your own citation contradicts you. Nalgene bottles are now made exclusively from polyester, which is not subject to post-process fluorination, and even if it were, there would be no reason for a company to spend the money to fluorinate consumer water bottles.
