Any recently-built home probably has plastic water supply pipes throughout. They're crazy easy (so, less and less-skilled labor required, so cheaper) to install, and the material's cheap. Unless you custom-build and pay a lot extra for copper, that's almost certainly what you're getting. Most anything canned in aluminum or steel is in contact with the plastic liner that ~all cans have. Veggies, beans, sauces, beer, et c. > Glass bottles are pretty rare for drinks these days You pay extra for it, but you can still easily find mineral water in glass. Soda, too, at least for Coca Cola and a bunch of alternative brands, is easy to find in glass. Beer and wine, obviously, though, at least for wine you pay a premium to get low-end wine in glass rather than in a plastic bag ("box wine").
