Old Bridge Mua standing, mid SDWIS violation third

29% of 56 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 29% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #768 of 29,740 among systems serving 500+.

The verdict

Old Bridge Mua lands in the middle third by violation volume (56), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (68,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 29% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 5 PFAS compounds (upper-third PFAS panel (> 4 compounds)).

How many violations vs. how serious, among peer systems

Old Bridge Mua 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 Old Bridge Mua. 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.
