BUTLER, Pa. (KDKA/AP) – A prosecutor says state police will try to determine who knew what about problems with high levels of lead in water that forced a western Pennsylvania elementary school to close for two days earlier this week.

Butler Area School District Superintendent Dale Lumley apologized to Irate parents of Summit Elementary students on Monday. Students were given bottled water for two days earlier this school year after water tests in August found lead, but the school remained open until it closed for more testing over two days earlier this week.

Lumley says a maintenance supervisor overseeing the issue misunderstood a directive from state environmental officials, but district emails suggest Lumley knew or should have known about the continuing problem in September.

Butler County District Attorney Richard Goldinger wants to know whether anybody’s criminally liable.

Meanwhile, the Butler Area Board of School Directors have approved a contract with the Butler Health System to perform blood work on the students and staff to test their lead levels.

officials say there will be on-site testing at the elementary school on Tuesday, Jan. 31 and Thursday, Feb. 2 from 9 a.m. to 3 p.m. Testing can also be done at Butler Health System Labs.

Also, the board says they will reimburse families that have testing done at their own family doctor.
