Key facts for Oregon
- Oregon Health Authority says public water suppliers must add service line inventory information to annual consumer confidence reports.
- Oregon's public inventory site says blank cells mean the state does not have inventory data for that water system and service line type.
- Portland says it never used lead pipes for service lines and removed all known lead service connectors by 1998.
- Portland says it submitted its service line inventory to the state in June 2024 certifying no lead service lines exist in its distribution system.
- Salem says it found no lead service lines in 402 inspected private service lines and reports a 95% confidence level for remaining not-inspected lines.
- EWEB says no lead service lines were found during its inventory and reports 95% confidence that there are no customer-owned lead service lines in its system.
What to do next
- Use Oregon's statewide service line inventory database first, then check your local utility's own map or lead page for address-level details.
- If your utility shows the service line as unknown, send the utility the photo or replacement documentation it requests so the inventory can be updated.
- If you are in Portland, Salem, or Eugene, review the utility's lead page for home-plumbing sources of lead because those systems report little or no lead service line presence.
