Health-based violations
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. Las Vegas's systems average 0.6 health-based violations each, ranking the highest of the 20 cities we track. Which specific system serves your address determines whether that history applies to you — check the list below rather than assuming.

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.
