MORO WATERWORKS (PWSID AR0000314) is a cws water system drawing from a groundwater source, regulated by the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act. It serves approximately 219 people in Moro, AR, and is subject to primacy enforcement by the Arkansas drinking-water program.

The system's federal compliance record contains 161 total violations, with 161 classified as health-based (MCL exceedances or treatment-technique failures). 2 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Total Coliform (RTCR). Recorded violations span 2005–2024.

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 Arkansas state drinking-water program's public portal.
