The verdict
Hooker sits in the upper third of the sitemap cohort by violation count (210), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 1,788 (mid served population (≤ 3,309)). 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.
