The verdict
Mississippi Palisades St Park - Plateau is in the lower third by violation count (3; lower-third violation load (≤ 21 violations)). A low count does not mean the system is unmonitored - monitoring and reporting violations still appear in SDWIS. Population served is smaller (25; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 33% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
