Seattle Public SchoolsDrinking Water Quality ProgramResults of Water Quality TestingforLAWTON ELEMENTARY SCHOOLUpdated September 2, 2019General Information:Plumbing piping materials: mainly copperRemediation plan:This remediation plan is based on a Water Quality policy approved by the School Board. The policy includes standards for the presence of lead, cadmium, copper, iron and other substances in drinking water.Sinks (S in the report) are not considered drinking water sources. We recognize that there is the potential for students to want to drink from classroom hand-washing sinks, so we test all of those. Where astudent’s choice to drink from a sink could be a problem, we post a reminder sign, as we do at all restroom sinks.Status:Policy Criteria:All sources meet the policy criteria. Drinking fountain in cafeteria will be removed.Follow-up monitoring: Will be performed in 2021-2022.Service: The school will be flushed after any breaks longer than five days.1
