Erin Brockovich, the water-safety activist who was immortalized in the eponymous film starring Julia Roberts, had her say on the water-safety scandal in Flint, Michigan on the Bill Maher show.

They don't want to pay for it, so they've gone the cheap route, and they throw ammonia in the water system.
