    Table note: *Two or more coliform found samples in any single month.

  • Applies to: Haloacetic Acids (HAA5)

    Table note: The Range of Levels Detected is based on individual samples, whereas the Highest Level Detected is the highest average of all HAA5 sample results collected at a location over a year. The source attributes the row's printed No status to those averages not exceeding MCL.

  • Applies to: Total Trihalomethanes (TTHM)

    The row prints Violation Yes. Page 11 identifies the historical violation period as 04/01/2025 - 06/30/2025; this annual-report evidence is not a current-notice assertion.

    The row prints Collection Date 2025 and was checked on linked report page 8; the table does not display an MCLG column.

  • Applies to: Copper, Lead

    Table note: The lead/copper table is followed by explanatory lead text; the table does not display an MCLG column.

  • Applies to: Fluoride*

    Table note: *Fluoride compounds are salts that form when the element, fluorine, combines with minerals in soil or rocks. The City of Boerne does not add fluoride to its drinking water.

  • Applies to: Gross Beta Particle Activity

    Table note: *EPA considers 50pCi/L to be the level of concern for beta particles.

  • Applies to: Calcium, Chloride, Conductivity, Magnesium, Manganese, Nickel, Sodium, Sulfate, Total Alkalinity as CaCO₃, Total Dissolved Solids, Total Hardness as CaCO₃

Violation Records

Violation records shown on this page

This section shows 0 system-scoped violation detail records currently included for City of Boerne Water System. Annual reports and current notices can use different timing and terminology.

No system-scoped violation detail records are included in the available reviewed records for this system. This is not an official compliance finding. Check the official utility, state, or EPA source for current compliance and notice information.

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

  • This record is based on official City of Boerne utility/report pages, the city-hosted 2025 Annual Drinking Water Quality Report, TCEQ verification path, and an attempted EPA ECHO identity cross-check path reviewed on June 9, 2026.
  • The 2025 report identifies City of Boerne Water System / TX1300001 and describes surface water and groundwater sources, including Boerne Lake, Canyon Lake through GBRA, and groundwater wells.
  • The EPA ECHO endpoint returned a rate-limit response, so population served and other ECHO-derived fields were not listed.
  • Population served was not listed from a usable official/source source; the local record omits the value rather than storing zero as a population count.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • This page may show summarized entries from available annual reports. It does not include a complete historical contaminant table.
  • 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.
