The verdict
Greenwood Isd sits in the upper third of the sitemap cohort by violation count (311), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (3,945; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 80% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
