I trust that they're working within frameworks they already have. Like when BPA blew up, lots of assurances that it was safe and tons of manufacturers saying their levels were "below allowed," completely sidestepping the issue that the question is: are the allowed levels even safe?

Similarly here, many of these chemicals don't have allowable levels or it's not known if the allowed amount is the right number. So someone certainly can say that the water being tested is passing tests. It's avoiding the question that the tests aren't right.

But ysk that EPA controls for city tap water are MUCH more rigorous than bottled water.
