Lead in School Drinking Water

To address the concerns about lead in drinking water, and to reduce children's overall exposure to lead in the environment, in 2021, the Legislature passed and governor signed Engrossed Second Substitute House Bill (E2SHB) 1139 (PDF). In passing the bill, the Legislature follows the advice of the federal Centers for Disease Control and Prevention (CDC) and Environmental Protection Agency that there is no known safe level of lead in a child's blood. Even low levels of lead exposure can cause permanent cognitive, academic, and behavioral difficulties in children. 

E2SHB 1139, now RCW 43.70.830 and RCW 28A.210.410, will require that drinking water outlets in school buildings built, or with all plumbing replaced, before 2016 be tested for the presence and level of lead contamination by June 30, 2026 and every five years thereafter. In addition, schools must notify community of lead test results and develop action plans for remediation if test results exceed the health-based standard of five parts per billion.

Concentration of lead in drinking water, even when it exceeds 15 ppb, is low compared to other sources of lead such as lead paint. The likelihood of drinking water at school alone causing an elevated blood lead level is very low. If you believe your child may have been exposed to lead in the environment, contact your healthcare provider.
