The verdict
Quebrada Arenas is in the lower third by violation count (0; 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 large (4,451; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. No violations are on record in this extract. No UCMR5 PFAS test appears for this system in this extract.
