Whitehall Twp Authority standing, high SDWIS violation third
54% of 369 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 54% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #3,843 of 29,740 among systems serving 500+.
The verdict
Whitehall Twp Authority sits in the upper third of the sitemap cohort by violation count (369), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (13,063; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 54% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).

How many violations vs. how serious, among peer systems
Whitehall Twp Authority 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.
