What this means for your tap water: a "health-based" violation means a system exceeded an actual contaminant safety threshold at some point — different from a paperwork or reporting violation, which is far more common and far less concerning. Every system serving St. Louis has a clean health-based record in EPA's database — no exceedances on file, though homes on private wells aren't covered by this data at all.

Water-system-level records, not address-specific — homes on private wells or served by a different system than listed here aren't reflected. A resolved violation means the system returned to compliance; it doesn't mean water quality is currently at risk.
