Lead in Missouri school drinking water

What Missouri 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.

MissouriPublishes nothing (not confirmed at source)

Publishing status: Publishes no results
Coverage: No published results, so there is no coverage to rate
Data vintage: currency not established by the evidence we hold
Evidence: reported, not verified at sourceChecked 2026-08-09; not confirmed at source

Action level

Published action level, as verified in 2026: Not recorded by this survey.

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 published results

We found no school lead testing results published by Missouri. That is not confirmed at source. The evidence is second-hand — typically EPA's coming-soon marker, which means the jurisdiction has no WIIN-grant results portal, not that it publishes nothing anywhere.

An absence of published results is a fact about disclosure, not about water. It says nothing about whether schools here have been tested, and nothing about what a test would find.

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: No · verified 2026: No
Action level: 2021 baseline: Unknown · verified 2026: not recorded
Publishes resultschanged: 2021 baseline: Unknown · verified 2026: No

Changed since the 2021 baseline: publishes results.

Source and verification

What we checked: https://www.epa.gov/dwcapacity/voluntary-school-and-child-care-lead-testing-and-reduction-state-grant-program-contacts

Machine readability: T4 — a programme exists but no public results surface was found

Verified research note

Our field note for Missouri, 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.

Resolves a NASBE Unknown to: no published results. Listed by EPA as 'coming soon'. ⚠️ 'Coming soon' means no WIIN-GRANT results portal; it does NOT prove the state publishes nothing anywhere. Confirm before publishing this as a negative. EPA's Voluntary School and Child Care Lead Testing state grant-program contacts index (retrieved 2026-08-09) is the authoritative index of state RESULTS portals; it is where this URL comes from.
