Public schools can order free testing to determine lead levels in drinking water under a new state program announced Monday. The testing program is in response to new requirements that all community water systems test public school drinking water upon request by school officials.  “Students should have access to clean drinking water at all times,” State Superintendent of Public Instruction Tom Torlakson said in a statement. “Students need fresh water, nutritious meals, and appropriate physical activity to be ready to learn in class.”
