Each local school board shall develop and implement a plan to test and, if necessary, remediate potable water from sources identified by the U.S. Environmental Protection Agency as high priority for testing, including bubbler-style and cooler-style drinking fountains, cafeteria or kitchen taps, classroom combination sinks and drinking fountains, and sinks known to be or visibly used for consumption. Such plan shall be consistent with guidance published by the U.S. Environmental Protection Agency or the Department of Health. The local school board shall give priority in the testing plan to schools whose school building was constructed, in whole or in part, before 1986. Each local school board shall submit such testing plan and report the results of any such test to the Department of Health. Each local school board shall take all steps necessary to notify parents if testing results indicate lead contamination that exceeds 10 parts per billion.
