THALIA WSC (PWSID TX0780013) 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 125 people in Crowell, TX, and is subject to primacy enforcement by the Texas drinking-water program.

The system's federal compliance record contains 100 total violations, with 100 classified as health-based (MCL exceedances or treatment-technique failures). 3 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Nitrate, Haloacetic Acids (HAA5). 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.
