I'm guessing that the rap against bottled water is the carcinogenic nitrosamine emittance from the new plastic.I realize that getting refills in glass bottles is best, but I try to reuse the same old plastic bottle at the machines, probably in error, thinking most of the emmissions are spent??
The same situation, I think, exits with a new car, with loads of gaseous nitrosamines being emmitted from the new plastic interior. In fact, I get an adverse reaction the second I step into a new car!!!
