UPDATE: The operations supervisor for Bradley County Schools says lead was found in 23 water sources.

A new law requires all Tennessee schools to test for lead in drinking water.

The schools that tested positive for lead are unknown at this time.

The report says the state tested 12 buildings, nine of which had lead levels above the limit allowed by the state.

The law specifically states schools built before 1998 must have water sources tested for lead.

Bradley County Schools says 141 water sources were tested back May.

One of the sources tested was considered to have a dangerous amount of lead.

Lead poisoning can cause serious problems. It can cause delayed development and learning issues in children. It can also cause other issues like fatigue, weight loss, and possible hearing loss. 

School officials say they took immediate action and shut off the water in those buildings to fix the problems before the school year started.

School officials say they are now in complete compliance with the state.

Director of Bradley County Schools Linda Cash told Channel 3, she is satisfied with how her staff handled the issue, saying they couldn't have responded in a better way.

As for Hamilton County Schools, they are coming up with a new policy to meet the state requirement.

They plan to present the policy by September and adopt the policy by October


ORIGINAL STORY: During summer testing, 23 water sources at Bradley County Schools were shown to have lead at or above standards established by the Environmental Protection Agency.

The tests were conducted in accordance with state law, which requires testing of drinking water sources for schools built before 1998.

The school system tells Channel 3 it took corrective action to fix each water source, and all Bradley County Schools are now in compliance with water safety standards.
