SEBRING, Ohio (AP) – Ohio regulators say two of 123 water samples taken at schools in a northeastern Ohio community are above the federal limits for lead and copper.

The state’s environmental agency said Tuesday that the latest tests from Sunday at three schools in Sebring near Youngstown found excessive lead levels in two drinking water fountains.

State officials say 22 samples showed evidence of lead below the federal limits while the rest had none.

Schools in the community are closed for a third day after officials said some homes showed high levels of contaminants this past summer.

Ohio’s environmental director has called for a criminal investigation, saying the local water plant operator failed to warn the public about the high lead tests and falsified reports.

The manager is denying the allegations.
