How the Portland Water Bureau Reduces Lead Exposure

The Portland Water Bureau:

  • Reduces corrosion of lead in plumbing by increasing the pH of the water. This pH adjustment has reduced lead in tap water by more than half.
  • Removes known sources of lead from the system. All known lead service connections (pigtails) were removed from the system by 1998.
  • Replaces large meters with lead components that serve water to at-risk populations. For more than ten years all replacement meters have been lead-free.


As part of our lead hazard reduction efforts, we provide resources through partnerships with community organizations and governmental agencies that conduct lead hazard reduction education and outreach services in the Portland-area. Grant application information is available here.

The Portland Water Bureau works cooperatively with the federal Environmental Protection Agency, the Oregon Health Authority, and Multnomah County to protect public health.
