An additional 33 schools in the Detroit Public Schools Community District have elevated levels of lead or copper in the drinking water — results that come less than a month after the district shut off water across all 106 school buildings.

The district released the latest round of test results for 52 schools Wednesday afternoon.

To date, 57 out of 86 schools where test results are in have been shown to have elevated levels of lead and/or copper this year. An additional 10 schools had been identified last year and new results are pending for them.

The district started the school year Sept. 4 using bottled water and water coolers. Superintendent Nikolai Vitti has proposed a $2-million plan to install water hydration stations in each school. He has said the hydration stations are better because they filter contaminants out of the drinking water.

"The hydration stations would be installed in all schools by the beginning of next school year districtwide and replace the need for water coolers," Vitti said in an email to staff.

Lead in drinking water goes well beyond Detroit

Fix the water, Detroit school officials are told

There would be a hydration station for every 100 students, in addition to one in each kitchen, faculty lounge and gym.

The hydration stations are being used elsewhere in the nation, including in Baltimore City Public Schools, where schools such as Hampstead Hill Academy have been using them. The school's principal, Matt Hornbeck, told the Free Press last week that parents, students and staff are fans of the system. He said it's tested one to two times a year for contaminants.

"It passes the test every time," Hornbeck said. "We’ve been really pleased with it. Kids and parents are excited to have the kids safely hydrated."

The district began testing all drinking water sources in every school — rather than randomly sampling sources — after tests this spring found elevated lead levels in eight schools.
