It serves approximately 11,250 people in Ardmore, OK, and is subject to primacy enforcement by the Oklahoma drinking-water program.

The system's federal compliance record contains 182 total violations, with 182 classified as health-based (MCL exceedances or treatment-technique failures). 9 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Haloacetic Acids (HAA5), Turbidity. Recorded violations span 1986–2025.

A historical violation does not necessarily describe current water quality, systems must notify customers and remediate, and monitoring-type violations often reflect reporting lapses rather than contamination. The most authoritative real-time source is the utility's annual Consumer Confidence Report.
