A road construction project on Warren and Brown streets near the hospital likely disturbed the sediment, officials said. The federal guidelines state lead levels must be under 15 parts per billion, and the water samples at the hospital tested within the range of 15 to 220 parts per billion.
Edwards, who exposed the massive lead water contamination in Flint, Mich., said more testing would be needed to pinpoint the exact cause of the “very high” levels of lead in the hospital water supply.

“What happened at that hospital is a mystery the likes of which I have never seen before,” he said. “There’s every indication it came from outside the hospital. Now, we did not have access — we were not able to get access to the samples that the utility has.”
He said the only reason the lead was found is because the hospital is required to test for lead and copper. The hospital is required to sample its water in the southeast addition every six months. The hospital met the current requirement for 2016, and will test again sometime in the first six months of 2017.
Officials said the valve connecting the hospital’s water supply to the main on Warren Street remains closed.
Michael Powell, the director of the city’s water department, said lead levels continue to test within acceptable ranges near the hospital.
