Wharton Water Dept standing, high SDWIS violation third
6,342 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 1% is middle-third health share (≤ 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #6,571 of 29,740 among systems serving 500+.
The verdict
Wharton Water Dept sits in the upper third of the sitemap cohort by violation count (220), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (6,342; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 1% (middle-third health share (≤ 23%)). UCMR5 detected 4 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).

How many violations vs. how serious, among peer systems
Wharton Water Dept 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.
