CHICAGO -- Chicago Public School officials say testing has found high levels of lead in the water of 99 of the district's schools.
Officials say all the schools had at least one sink or water fountain that had water with more lead than the federal Environmental Protection Agency's "action level" of 15 parts per billion.
Testing of the water in Chicago's public schools began after the discovery of lead in Flint, Michigan's water. The brain development of young children can be impaired by small amounts of the metal.
Laboratory results have come back for 263 of Chicago's more than 500 public schools.
District officials say water at all public schools will be tested. However, they have said how the district will replace plumbing and fixtures that may have caused high lead levels.
