Source report notes

Source: Missoula Water 2026 report covering 2025. Retrieved 2026-07-31.

  • Applies to: PFOA

    8 ppt, range 0 - 2.8, source-printed MCL 4.0 ppt. The table has no violation or compliance column, so no violation, compliance, advisory, exposure, or safety status is inferred. Annual-report values describe only the cited report sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

  • Applies to: PFOS

    5 ppt, range 0 - 3.5, source-printed MCL 4.0 ppt. The table has no violation or compliance column, so no violation, compliance, advisory, exposure, or safety status is inferred. Annual-report values describe only the cited report sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

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 PFOA and PFOS from physical PDF page 6. The source table has no violation column, so this profile does not infer a violation, compliance, advisory, exposure, or safety status.
  • The report separately lists lithium at 15 ppb, range ND - 15, with collection years 2023 - 2025. That material omitted-row context remains visible above and is not a current household result.
  • The report separately lists a PFAS mixture HI of 0.27, range 0 - 0.27, and prints a threshold of 1.0. The source units column prints ppt; this profile does not normalize or interpret that unit.
  • The report says the HI applies to PFHxS, PFNA, HFPO-DA, and PFBS and prints 'Compliance requires HI <= 1.0.' This is preserved as source wording, not an independent current compliance conclusion.
  • The report says enforceable violations for PFAS MCL exceedances will not be issued until the second quarter of 2029 and says EPA proposed extending the compliance deadline to 2031. These are report statements, not an independent current regulatory conclusion.
  • Missoula Water, PWSID MT0000294, is the reviewed municipal system. The City separately publishes a report for Phantom Hills Water System, PWSID MT0004379, says it serves the Ranch Club, and says it is not connected to the main Missoula Water system.
  • This profile does not identify the provider for every Missoula address. Confirm with a current bill or official lookup. Phantom Hills remains unpromoted and route-absent.
  • The Alert Center displayed no active alerts at the July 31, 2026 observation time. That can change and is not proof of current compliance or absence of a notice; check official paths for current instructions.
  • 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.
