Water Quality Snapshot: SJWTX TRIPLE PEAK PLANT

SJWTX TRIPLE PEAK PLANT is a private-owned community water system that delivers drinking water to 32,973 residents in CANYON LAKE, Texas (Comal County) through 10,412 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 107 total violations for this system , of which 24 (22%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 72 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is TTHM, recorded in 16 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 4 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 28.4 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Texas, EPA tracks 7,351 public water systems serving 33,253,313 people, with 746,210 cumulative violations and 162,945 health-based violations on record. About 90% of systems in the state carry at least one violation, and state-wide the average per system is 101.5 violations. SJWTX TRIPLE PEAK PLANT's 107 violations sit above the Texas average. Statewide, 1,068 of 1,147 UCMR5-tested systems have reported PFAS detections (93.1%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
