Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 13 total violations for this system , of which 13 (100%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. The most recent violation on record dates to 2014.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 9 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 14 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.
