Lead Service Line Compliance in Oregon Water Systems
Overview
Oregon's water utilities serve nearly 4 million people across 2,531 public water systems. As of October 2024, these systems have completed their initial lead service line (LSL) inventories under the EPA's Lead and Copper Rule Revisions (LCRR). The inventory process is a critical first step: utilities must document which pipes are made of lead, which are not, and which remain unknown — then develop plans to replace the unknown and confirmed lead lines over time.
What the data shows
Oregon's water systems reported their October 2024 inventories to the state. The state primacy agency — Oregon Health & Science University's Drinking Water Program — oversees compliance with LCRR requirements and works with utilities to meet replacement timelines and public notification rules.
The inventory itself is just the beginning. Under LCRR, utilities must:
- Complete initial inventories (done by October 2024)
- Replace all lead service lines on the utility's side within 10 years
- Offer financial assistance to customers for replacement of the customer-owned portion
- Notify the public of findings and replacement schedules
What happens next
Once inventories are filed, the focus shifts to replacement. Utilities must prioritize lines serving schools, childcare facilities, and other sensitive populations. Oregon utilities should be developing and publishing their replacement plans, which residents can request from their local water provider.
If your utility has identified unknown lines in your neighborhood, you have the right to:
- Request testing or inspection of your service line
- Ask about replacement timelines and cost-share programs
- Access the utility's inventory data and replacement plan
State oversight
Oregon's Drinking Water Program monitors utility compliance and can take enforcement action if systems fail to meet LCRR deadlines or requirements. You can contact your water utility directly to learn your system's status, review the inventory findings for your address, and ask about replacement programs in your area.
Next steps for residents
- Contact your water utility and ask for the LCRR inventory results for your address and service line status
- Request a copy of your utility's LSL replacement plan and timeline
- Ask about financial assistance programs for private (customer-owned) line replacement
- Report any service line concerns (discolored water, slow flow, corrosion) to your utility promptly
