Consumer Confidence Report status
CONCAN WSC must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for CONCAN WSC.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Texas’s official records. Always confirm current status with Texas before making decisions based on this information.

CONCAN WSC is one of 1,859 community water systems in Texas in the 501 to 3,300 people size category, serving 1,488 people from surface water.
As of August 1, 2026, its federal record holds 45 entries between 2005 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 45, 39 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.

Common questions
Is CONCAN WSC required to publish a Consumer Confidence Report?
- Yes. CONCAN WSC is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is CONCAN WSC’s next Consumer Confidence Report due?
- CONCAN WSC’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CONCAN WSC have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for CONCAN WSC.
What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
