3,903 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 10% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #9,012 of 29,740 among systems serving 500+.

The verdict

North Brookfield Water Department sits in the upper third of the sitemap cohort by violation count (78), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (3,903; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 10% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.

How many violations vs. how serious, among peer systems

North Brookfield Water Department 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 North Brookfield Water Department. 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.
