Source report notes
Source: Green Bay Water Utility 2025 Annual Drinking Water Report. Retrieved 2026-08-03.
- Applies to: TTHM Site D9
0, row-local range 18.6–48.6, MCLG 0, and MCL 80. D9 has the highest printed TTHM Detected Level, but this row is not a synthesized cross-site range or complete distribution summary. The table prints no row-level violation field. Annual-report values and printed status describe only the cited 2025 report period. They are not a live compliance feed, advisory determination, address-level result, household-tap result, exposure finding, or safety conclusion.
- Applies to: HAA5 Site D9
2, row-local range 6.6–14.0, source-printed Goal MCLG 60, and MCL 60. D9 has the highest printed HAA5 Detected Level. The unusual HAA5 MCLG 60 is preserved literally and flagged without correction. The table prints no row-level violation field. Annual-report values and printed status describe only the cited 2025 report period. They are not a live compliance feed, advisory determination, address-level result, household-tap result, exposure finding, 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 system preview shows only the D9 TTHM and HAA5 rows from physical PDF page 4. The complete report extraction separately retains the D15, D17, and D22 rows and all other report result rows without expanding the system preview.
- D9 TTHM preserves Detected Level 28.0 ppb and row-local range 18.6–48.6. D9 HAA5 preserves Detected Level 9.2 ppb and row-local range 6.6–14.0. No cross-site range or complete distribution summary is synthesized.
- The source-printed HAA5 Goal MCLG 60 is unusual and is preserved literally without correction or normalization.
- Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
- The old 2007 state fields conflict with completed underlying records and lack current utility corroboration. They are not converted into a live advisory, present-day noncompliance, or resolution claim.
- The utility flushing path is operational context, not a health advisory. Contradictory PFAS web prose is excluded from public claims.
- The reviewed Green Bay relationship is nonexclusive and does not identify the provider for an address.
- 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.
