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 Castle Hills provider context, the SAWS Castle Hills report page, the official 2025 SAWS Castle Hills Water Quality Report, TCEQ verification path, and an attempted EPA ECHO identity cross-check reviewed on June 8, 2026.
- Address-level service can vary. Confirm the serving provider with a bill, account portal, utility, city, or state source.
- EPA ECHO returned a throttled response, so no field in this record relies on ECHO.
- 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 2025 report as groundwater from the Edwards Aquifer; this is report 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.
