I've had the suspicion that a lot of chemicals are leaking into the water because plumbing is an old enough field that there's a lot of "that's how we always did it".. If you've ever sniffed at new plumbing supplies, you're not doubting that they will leak something, after all, if something has a smell, it's giving off something to its surroundings. My principles when drinking tap water is to let it run until cool and never use warm water for drinking or eating.
