Richmond County Water System standing, high SDWIS violation third
28% of 163 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 28% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #2,471 of 29,740 among systems serving 500+.
The verdict
Richmond County Water System sits in the upper third of the sitemap cohort by violation count (163), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (22,387; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 28% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 5 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
