"Laura Dumais with Public Employees for Environmental Responsibility (PEER) says the parks aren't properly maintaining their water distribution. "The way they're doing it is essentially just putting in a lot of chlorine and hoping that will take out anything that's bad in there" said Dumais. "What we're saying is what they really have to do is affirmatively go in, inspect and clean the tank in the first place. Then they'll have to use less chlorine, which obviously is a chemical that, in itself, can have harmful effects for people.""
