Since the answer to both of those questions is no, it's more than a PR move.
Just like the water in the “milk” cartons.
They might as well just sell water like Canadians sell milk —in simple plastic bags and then you put the bag in your favorite mug or whatever.

> Each time EPA establishes a standard for a contaminant, FDA either adopts it for bottled water or finds that the standard isn’t necessary for bottled water.
> In some cases, standards for bottled water and tap water differ. For example, because lead can leach from pipes as water travels from water utilities to home faucets, EPA has set its limit for lead in tap water at 15 parts per billion (ppb). For bottled water, for which lead pipes aren’t used, the lead limit is set at 5 ppb.
So it could go in either direction though leans toward tight coordination. Enlightening to know there is more scrutiny there.
That aside, the horrible taste alone should be enough to dissuade people with a known safe alternative from drinking bottled water.
