The latest on lead in Hillsborough school water

The Hillsborough County School District has wrapped up its water testing and posted detailed results, school by school, on its website.

District spokesmen say all issues were corrected. Fewer than 2 percent of the 11,595 fixtures tested showed readings of more than 15 parts per billion, a standard they consider safe according to guidelines by the U.S. Environmental Protection Agency.

However, a Times investigation found that the 15 parts per billion measure comes from public utilities regulation. Public health experts do not consider that threshold to be safe, especially for young children. District leaders took issue with the Times, which criticized them for keeping the water testing under wraps for more than a year.

Shortly after the Times report appeared, the district began posting the full results, school by school, so parents, students and employees could research the lower amounts of lead as well.

The detailed reports show that some schools were retested to make sure the levels were sufficiently low after repairs were made. "There were NO school-wide issues," the district said in a news release. "The majority of the issues were found in fixtures like hand washing sinks or backflow prevention devices."
