buildings built before 1989 face a higher risk for lead contamination.

“When water stays stagnant for long periods of time like in contact with old plumbing materials that have lead in them, you’ve got three things acting together,” Fumerton explained. “You’ve got the properties of tap water itself, so some is soft and acidic and tends to leach metals out of pipes.”

“We know that lead can impact development in the brains in young children and fetuses… There’s no good amount of lead … so to the degree that we can reduce the level of lead in drinking water, we can and should do so,” she said. “And particularly for those vulnerable populations, so schools are an easy target to address.”
