(a) Beginning in the 2018-2019 school year, and every school year thereafter, school facilities where children attend school may be tested for lead levels in the drinking water and any school facility whose testing shows lead levels in excess of the maximum contaminant level goal or milligrams per liter as set by the United States Environmental Protection Agency's National Primary Drinking Water Regulations shall immediately implement a plan to ensure no child or adult is exposed to lead contamination drinking water and that alternative sources of drinking water are made available.

(b) If a school entity does not test lead levels under paragraph (a) the school entity shall, at a public meeting, discuss lead issues in the school facilities.

(c) If a test of lead levels under subsection (a) is elevated, the level shall be reported to the Department of Education and posted on the department's publicly accessible Internet website.
