Source report notes

Source: City of Caldwell 2025 Annual Water Quality Report. Retrieved 2026-08-09.

  • Applies to: Arsenic

    The source prints 2025 arsenic 9.24 ppb, range 3.90 - 9.24 ppb, MCL 10, MCLG 0, and Violation No. The report's separate arsenic health information remains visible in the profile. Annual-report values describe only the cited report period. 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.

  • Applies to: Uranium

    The source prints 2025 uranium 20.00 ppb, range ND - 20.00 ppb, MCL 30, MCLG 0, and Violation No. Annual-report values describe only the cited report period. 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.

Review the linked source report for definitions, footnotes, and official wording.

Important limitation

Profile summary note

This page summarizes public records reviewed by this site. It does not replace official notices, utility updates, or state drinking water information.

System profile limitations

  • The bounded preview shows only 2025 arsenic and uranium rows from physical PDF page 5.
  • EPA identity information reviewed August 9, 2026 lists population 74,000 and 25,000 service connections; these system-level counts do not establish service at an address.
  • The summarized entries remain alongside arsenic health information, lead inventory and sampling, alpha-emitter, and lithium context.
  • The 15-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.
  • This page summarizes available public records. It may not include every update, notice, or urgent official advisory.
