Lead in Oregon school drinking water

What Oregon publishes about lead testing in its schools’ drinking water, what those numbers cover, and how we checked it. One row of a 51-jurisdiction survey, verified jurisdiction by jurisdiction rather than compiled from a single list.

Action level

Published action level, as verified in 2026: 15 ppb

Action levels are not comparable between jurisdictions: across the 51 we surveyed they run from 1 ppb to 20 ppb, so a share of results above “the action level” measures the threshold as much as it measures the water. We never rank states on it. Where a jurisdiction explains how its own level was set, the verified research note at the foot of this page records the explanation verbatim.

No statistics on this page yet

Oregon publishes results, but we have not yet ingested them row by row, so this page carries no counts or rates for it — only what the survey verified about the publication itself. We publish a figure once we hold the rows it is computed from, and not before. The jurisdiction’s own results are linked below.

What changed since 2021

The baseline is the National Association of State Boards of Education’s 2021 survey. Every 2026 value below was re-checked for this survey; a value that did not move is a finding too.

Testing required: 2021 baseline: Yes · verified 2026: Yes
Action level: 2021 baseline: 15 · verified 2026: 15
Publishes results: 2021 baseline: Yes · verified 2026: Yes

Nothing in this row moved between the 2021 baseline and our 2026 verification.

Source and verification

What we checked: https://www.oregon.gov/oha/PH/HEALTHYENVIRONMENTS/HEALTHYNEIGHBORHOODS/HEALTHYSCHOOLFACILITIES/Pages/data.aspx
Checked on: 2026-08-09 — confirmed at source
Machine readability: T2 — structured but needs extraction (dashboard or web app)

Verified research note

Our field note for Oregon, published verbatim rather than summarised. Where it quotes a figure from a source, that is the source’s own number reproduced as we recorded it, not a rate we computed — everything we compute states its denominator and its unit.

A THIRD failure mode, distinct from 'does not publish' and 'publishes almost nothing': Oregon publishes an ArcGIS MapSeries of school lead results, but it is a ONE-TIME 2016 dataset and OHA itself warns 'This map contains data submitted in 2016. Schools continue to test, fix problems and retest.' A parent checking it today learns nothing current. Counting Oregon as 'shares results publicly' without the vintage would be misleading.
