Reported measures, ranges, regulatory criteria, and source-printed violation fields remain distinct from current notices, address-level service, exposure, household-tap conditions, compliance, or safety. A reviewed city relationship does not identify the provider for an address or prove exclusive service.

Lewiston identity, service-line, lead, and UCMR context: Official data snapshot August 9, 2026

The PDF does not print a PWSID; the official City archive and EPA identity record provide the bounded ID2350014 crosswalk. The report says no lead service lines had been found to date and a few hundred service lines were listed as unknown for verification by the end of 2026. Its 2025 lead row prints 1 ppb, a high of 3.8 ppb, zero samples exceeding the 15 ppb action level, and No. Additional monitoring prints lithium 0.02988 mg/L, PFBS 0.0000056 mg/L, PFHxA 0.0000043 mg/L, and PFPeA 0.0000047 mg/L. These report fields do not establish present-day inventory completeness, compliance, exposure, household-tap conditions, or safety.

This is a point-in-time official regulatory data snapshot, not a live notice, current compliance conclusion, or tap-level safety conclusion. Open the official source , then open Review City of Lewiston news . The official report archive and city news path are bounded current-information resources, not a complete notice inventory or proof that no alert, advisory, outage, or instruction exists.

EPA identity information reviewed August 9, 2026 lists population 15,001 and 5,963 service connections; these system-level counts do not establish service at an address.
The summarized entries remain separate from service-line inventory, lead sampling, and UCMR report context.
The Clearwater River and well statement is annual system-level context and does not establish the source serving an address.
The reviewed city relationship is navigation context only. It is nonexclusive and does not identify the provider for an address.
Idaho and provider paths were reviewed on August 9, 2026. These mutable observations do not establish that every relevant notice was found or that no notice exists.
Annual-report values, source-printed row fields, supplier context, sampling footnotes, and mutable alerts are distinct source types and must not be collapsed into one current-status statement.
Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
This page shows summarized entries from the available report. It does not include a complete contaminant or violation table.
Missing fields are not findings. They mean the field is not shown on this page from the records currently available.
