MCINTOSH CO. RWD #5 (PWSID OK3004939) 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 1,900 people in Checotah, OK, and is subject to primacy enforcement by the Oklahoma drinking-water program.

The system's federal compliance record contains 146 total violations, with 146 classified as health-based (MCL exceedances or treatment-technique failures). 2 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Gross Alpha. Recorded violations span 2015–2025.

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. For enforcement history and corrective-action orders, consult EPA ECHO and the Oklahoma state drinking-water program's public portal.
