Source report notes

Source: Rochester 2025 Drinking Water Report. Retrieved 2026-08-08.

  • Applies to: Total Trihalomethanes (TTHMs)

    9 ppb, range 4.40 - 16.00, MCL 80, and printed Violation NO. Annual-report values and printed status describe only the cited report period. A range endpoint is not the compliance statistic. These fields are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion. The reviewed relationship does not identify the provider for an address or prove exclusive service.

  • Applies to: Total Haloacetic Acids (HAA)

    1 ppb, range 1.20 - 5.50, MCL 60, and printed Violation NO. The lead-monitoring documentation limitation on physical page 3 remains mandatory context. Annual-report values and printed status describe only the cited report period. A range endpoint is not the compliance statistic. These fields are not a current compliance feed, advisory determination, address-level result, household-tap result, exposure conclusion, or safety conclusion. The reviewed relationship does not identify the provider for an address or prove exclusive service.

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 TTHM and HAA from physical PDF page 5. The page 3 lead-documentation limitation, PFAS, service-line, and notice material remains visible context rather than additional preview rows.
  • The source's NO row flags and available lead results do not erase the incomplete-documentation statement or inability to establish firm lead levels at report time.
  • The 29 wells, reported depth range, and named aquifers are annual system-level context and do not identify which well or aquifer serves an address.
  • The official provider brand differs from the federal reported system name. This limited relationship does not prove the provider for every Rochester address.
  • Provider paths were reviewed on August 8, 2026. Those mutable observations support navigation only and do not establish that every relevant notice was found or that no notice exists.
  • Annual-report values and printed flags are historical report-period context only. They do not establish present-day compliance or absence of a current notice.
  • 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.
