What Connecticut 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.
ConnecticutPublishes nothing (not confirmed at source)
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.
We found no school lead testing results published by Connecticut. 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.
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.
Changed since the 2021 baseline: testing required, publishes results.
Our field note for Connecticut, 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.
STILL UNCONFIRMED, AND DELIBERATELY SO -- re-checked 2026-08-15 and left secondary. Of the three rows that rested on EPA's 'coming soon' marker alone, Alaska and Missouri both turned out to publish; Connecticut is the one where the search came back empty, and an empty search is NOT evidence of absence. That is this project's own rule and it is what put Ohio and Texas in the wrong column once, so the row keeps none-unconfirmed rather than being promoted to none-confirmed on a failure to find. WHAT WAS ACTUALLY CHECKED on 2026-08-15, which is the methodology 3 procedure in full: HEALTH -- DPH, the agency EPA's index names, across its rebuilt site and its own search twice; only guidance survives (Lead and Copper Rule pages, the schools/childcare fact sheet, the Lead in Drinking Water and water-cooler PDFs) and the Lead Poisoning Prevention and Treatment Working Group page carries meeting decks, no results. EDUCATION -- SDE publishes lead-poisoning education guidelines only, no water results. ENVIRONMENT -- DEEP's Potable Water Program is contaminated-site remediation, unrelated to schools. Also checked the Office of Early Childhood, which mandates biennial lead testing for licensed child care centres but takes the certified results as a LICENSING submission and publishes none, and data.ct.gov, which carries childhood blood-lead surveillance but no school water dataset. CONTEXT that makes the absence plausible rather than proven: Connecticut does not generally require schools to test -- only those on their own water source -- and its WIIN work is a voluntary DPH project targeting schools in the five cities with the highest childhood blood-lead levels (New Haven, Waterbury, Bridgeport, Hartford, Meriden), for which no public results surface was found even though EPA requires grant-funded results to be made public. ⚠️ TO CLOSE THIS: the standard Georgia met was affirmative evidence of emptiness, not a fruitless search -- so what is needed is either a DPH statement, or the WIIN project's results surface located and shown to be empty or absent. ⚠️ portal.ct.gov and DPH were both recently rebuilt and many old paths 404; a migration 404 is not evidence about disclosure.
