CASSIE WATER SYSTEM

PlainEnviro's health-based SDWIS extract covers monitoring and reporting violations only -- it does not include unresolved enforcement actions in progress or corrective steps a utility has taken since the extract date. 4 distinct EPA contaminant codes appear in this system's record, including Long Term 2 Enhanced Surface Water Treatment Rule, Lead and Copper Rule, Surface Water Treatment Rule. Recorded violations span 1995–2025. Day-to-day primacy enforcement for this system runs through the Missouri drinking-water program, not EPA directly.

A historical health-based record does not necessarily describe current water quality or compliance. The most authoritative current source is the utility's annual Consumer Confidence Report. For enforcement history and corrective-action orders, consult EPA ECHO and the Missouri state drinking-water program's public portal.
