BOSTON — Massachusetts officials say water tests at more than 160 of the state’s public schools showed levels of lead above the regulatory limit.

The Massachusetts Department of Environmental Protection says it has tested water at 450 school buildings as part of a statewide effort to eliminate lead from their drinking water. Tests at 164 schools found lead levels higher than 15 parts per billion, the level at which corrective action must be taken under federal rules.
