Water Quality Snapshot: TUTTLE

TUTTLE is a local-owned community water system that delivers drinking water to 4,500 residents in TUTTLE, Oklahoma (Grady County) through 2,485 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 288 total violations for this system , of which 120 (42%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 140 monitoring and reporting violations are on file. The most recent violation on record dates to 2024.

The most frequently cited contaminant at this system is Nitrate-Nitrite, recorded in 80 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 25 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Oklahoma, EPA tracks 1,262 public water systems serving 3,699,452 people, with 336,706 cumulative violations and 113,804 health-based violations on record. About 98% of systems in the state carry at least one violation, and state-wide the average per system is 266.8 violations. TUTTLE's 288 violations sit above the Oklahoma average. Statewide, 101 of 166 UCMR5-tested systems have reported PFAS detections (60.8%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
