Ellen Ishkanian of the Boston Globe has this update.
Last month [Chief Operating Officer Dori] Zaleznik told the Globe  test results showed no problems.
On Thursday, Zaleznik clarified those remarks, saying the tests showed that there were no problems with the water at the drinking fountain tested. But, she said, the 2010 tests did show a level above the EPA standard of 15 parts per billion from water at one faucet at a sink in the school.
“When I answered that question about 2010 I was talking about the water tested at the drinking fountain, which was not above the threshold,” she said. “The sink where the level above the threshold was found was not used in food preparation, or for drinking water.”
