GARY WSC (PWSID TX1830008) 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 1,050 people in Gary, TX, and is subject to primacy enforcement by the Texas drinking-water program.

The system's federal compliance record contains 95 total violations, with 95 classified as health-based (MCL exceedances or treatment-technique failures). 3 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Combined Radium 226/228, Gross Alpha. Recorded violations span 2014–2025.

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 Texas state drinking-water program's public portal.
