The verdict

Heavener Utility Auth - Psg sits in the upper third of the sitemap cohort by violation count (290), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 3,000 (mid served population (≤ 3,309)). Health-based share is 58% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).

How many violations vs. how serious, among peer systems

Heavener Utility Auth - Psg plotted against 29 peer public water systems (500+ people served), by total violation count (x) and the share of those violations that are health-based (y). The crosshair sits at this sample's own median on each axis. A high violation count does not automatically mean a serious record: most monitoring and reporting violations are minor, not health-based.

30 public water systems (500+ people served), EPA SDWIS current release.

How to read this

Each dot is one public water system; the highlighted dot is Heavener Utility Auth - Psg. A system to the right has more recorded violations; a system higher up has a larger share of those violations classified health-based rather than monitoring or reporting.

Rare but serious: few violations, but most of them are health-based.
Frequent, mostly paperwork: many violations, but mostly monitoring or reporting, not health-based.
Clean record: below-median on both counts, the tinted corner.
