BOSTON (AP) – 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.
Schools with higher levels have replaced water fixtures and plumbing, turned off taps or posted signs not to drink the water.
Officials say most water supplied to schools is below the regulatory limit but can be contaminated by lead in pipes, soldering or fixtures.
The state plans to sample water at 930 schools by January.
