STILLWATER UTILITIES AUTHORITY

STILLWATER UTILITIES AUTHORITY (PWSID OK1021220) is a cws water system drawing from a surface water source, regulated by the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act. It serves approximately 53,000 people in Stillwater, OK, and is subject to primacy enforcement by the Oklahoma drinking-water program.

The system's federal compliance record contains 45 total violations, with 45 classified as health-based (MCL exceedances or treatment-technique failures). 5 distinct contaminants have been cited, including Chloroform, Arsenic, Total Coliform (RTCR). Recorded violations span 1988–2023.

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.
