The verdict
Alturas lands in the middle third by violation volume (53), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (6,242; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 4% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
