PERRY WATER & LIGHT DEPT (PWSID OK1021206) 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 5,230 people in Perry, OK, and is subject to primacy enforcement by the Oklahoma drinking-water program.
The system's federal compliance record contains 110 total violations, with 110 classified as health-based (MCL exceedances or treatment-technique failures). 8 distinct contaminants have been cited, including Chloroform, Total Trihalomethanes (TTHM), Haloacetic Acids (HAA5). Recorded violations span 1980–2025.
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.
