  • Applies to: Barium

    The official HTML checksum, not the generated rendering, governs source identity. The table prints 0.043 ppm as the highest result, 0.024-0.043 as the range, and No in the violation column. Annual-report values and printed status fields describe only the cited report and sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

  • Applies to: Nitrate

    The official HTML checksum, not the generated rendering, governs source identity. The table prints 5.3 ppm as the highest result, 0.509-5.3 as the range, and No in the violation column. Annual-report values and printed status fields describe only the cited report and sample period. They are not a current compliance feed, advisory determination, address-level result, household-tap result, or safety conclusion.

  • Applies to: Nitrate

    Table note: The report says nitrate levels may rise quickly for short periods because of rainfall or agricultural activity and directs caregivers of infants to seek health-care-provider advice.

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 Barium and Nitrate from physical review page 37. Other report content is not reproduced.
  • The official source is web-native HTML. The 38-page generated PDF was used only to verify visual alignment and is not presented as the official source.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • The report's March 2026 turbidity-monitoring interruption remains attributed informational context and is not converted into a current advisory, compliance, resolution, or safety conclusion.
  • The linked official quality, main-break, contact, report, provider, and state pages can change after July 30, 2026. Check those paths for current instructions; this profile does not claim that no active notice exists.
  • Annual-report values and printed No fields describe only cited rows and periods. They are not a live compliance feed, advisory determination, household-tap result, or safety conclusion.
  • 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.
