The source water you receive does not contain lead or copper. However, lead and copper can leach into your water from building plumbing systems. Brass fixtures, regardless of age, generally contain some lead also.
Compliance is determined on a regional system basis.
As shown in the table below, the lead concentration value currently exceeds the Action Level, requiring annual public education and additional treatment improvements. Because the concentration level is not expected to change significantly until after the new Tolt River treatment facilities are in operation, Seattle entered into a Bilateral Agreement with the Department of Health in May 1997, allowing us to suspend home tap water sampling until the new facilities are in operation. Infants and children who drink water containing lead in excess of the action levels could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
