Source report notes

  • Applies to: Copper, Lead, Haloacetic Acids (HAA5), Total Trihalomethanes (TTHM), Barium, Fluoride, Uranium, Xylenes, CL2

    Source-printed values are preserved without inferring current status, compliance, water safety, or household conditions.

  • Applies to: Haloacetic Acids (HAA5), Total Trihalomethanes (TTHM)

    Table note: *The value in the Highest Level or Average Detected column is the highest average of all TTHM sample results collected at a location over a year.

  • Applies to: Nitrate (measured as Nitrogen)

    The row continues from the page 4 table header. The printed Highest Level Detected value is 2 while the printed Range of Levels Detected is 2.08 – 2.2; both are preserved without reconciliation.

System profile limitations

  • This record is based on official City of Leon Valley utility/context pages, the city-hosted 2024 Annual Drinking Water Quality Report, TCEQ verification path, and an EPA ECHO identity cross-check path reviewed on June 8, 2026.
  • Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
  • Population served was not listed from a usable source; the local record omits the value rather than storing zero as a population count.
  • Source water is summarized from the city utility page and 2024 report as groundwater from the Edwards Aquifer or Edwards Formation wells; this is report and utility context, not a complete live source-water inventory.
  • 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.
