DETROIT— Elevated lead or copper levels have been found in water in 19 Detroit schools amid ongoing testing at schools around the country in response to the crisis in Flint, Michigan.
Detroit Public Schools began collecting water samples two weeks ago. District spokeswoman Michelle Zdrodowski said then that a number of factors, including the lead-tainted water crisis in nearby Flint, led to “proactive and precautionary” testing.
