PAPPAS & CO (MENDOTA) (PWSID CA1009039) 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 36 people in Fresno, CA, and is subject to primacy enforcement by the California drinking-water program.

The system's federal compliance record contains 176 total violations, with 176 classified as health-based (MCL exceedances or treatment-technique failures). 5 distinct contaminants have been cited, including Total Trihalomethanes (TTHM), Arsenic, Haloacetic Acids (HAA5). Recorded violations span 2008–2024.

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 California state drinking-water program's public portal.
