"Tests last summer showed troubling levels of lead in the water at Summit Township Elementary School, perched on a quiet hilltop outside Butler, Pa. But for the next five months, no one told the parents of Summit’s 250 students.

When officials alerted families to the potential lead contamination in January, the dominoes fell quickly. The district superintendent and assistant superintendent resigned. The school board hired an independent investigator. Administrators shuttered Summit and moved students to another building several miles away. And the mother of a kindergartner filed a federal lawsuit, saying the inaction had created “a school full of poisonous drinking water.”

Nearly two years after a water crisis in Flint, Mich., triggered renewed pressure for lead testing and remediation in schools across the country, many districts continue to stumble. "
