Cswa Chehalem Springs standing, high SDWIS violation third

130 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 22% is middle-third health share (≤ 23%).

The verdict

Cswa Chehalem Springs sits in the upper third of the sitemap cohort by violation count (110), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (130; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 22% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.

How many violations vs. how serious, among peer systems

Cswa Chehalem Springs 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.

How to read this

Each dot is one public water system; the highlighted dot is Cswa Chehalem Springs. 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.
