The verdict
Minnewaukan City Of is in the lower third by violation count (18; 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 (224; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 22% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
