The verdict
Siam Utility District sits in the upper third of the sitemap cohort by violation count (94), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (3,319; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is only 0% - almost all of this trail is monitoring or reporting. No UCMR5 PFAS test appears for this system in this extract.
