Water Quality Snapshot: EMHOUSE WATER SYSTEM

EMHOUSE WATER SYSTEM is a local-owned community water system that delivers drinking water to 1,146 residents in CORSICANA, Texas (Navarro County) through 382 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 37 total violations for this system , of which 19 (51%) 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 2025.

The most frequently cited contaminant at this system is TTHM, recorded in 15 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 0.0061 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. EMHOUSE WATER SYSTEM's 37 violations sit below the Texas average. Statewide, 1,068 of 1,147 UCMR5-tested systems have reported PFAS detections (93.1%).
