"The Environmental Protection Agency’s (EPA) proposal to address lead in water isn’t as aggressive as it could be, the agency’s independent science advisers, as well as outside groups, said Monday.
At a hearing of the EPA’s Science Advisory Board (SAB), both members and others from environment and public health groups said the agency should do more to replace the lead service lines that connect an estimated 6 million houses to the water main, contaminating water as it runs through the pipes.
The October proposal from the EPA doesn’t lower the 15 parts per billion (ppb) lead action level, instead adding a 10 ppb “trigger level” that pushes cities to add treatments to water to counter the lead."
