Water Quality Snapshot: SARDIS LONE ELM WSC

SARDIS LONE ELM WSC is a local-owned community water system that delivers drinking water to 20,736 residents in MIDLOTHIAN, Texas (Ellis County) through 6,768 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 17 total violations for this system , of which 6 (35%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 6 monitoring and reporting violations are on file. The most recent violation on record dates to 2015.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 4 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 5 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 179.5 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. SARDIS LONE ELM WSC's 17 violations sit below 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.
