Water Quality Snapshot: US DEPARTMENT OF ENERGY PANTEX PLANT

US DEPARTMENT OF ENERGY PANTEX PLANT is a federal-owned non-transient non-community water system that delivers drinking water to 4,600 residents in AMARILLO, Texas (Carson County) through 3 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 11 total violations for this system , of which 4 (36%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 5 monitoring and reporting violations are on file. The most recent violation on record dates to 2014.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 4 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 67.8 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. US DEPARTMENT OF ENERGY PANTEX PLANT's 11 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.
