Saluda Co W&S Authority (4120001) standing, high SDWIS violation third
98% of 172 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 98% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #8,185 of 29,740 among systems serving 500+.
The verdict
Saluda Co W&S Authority (4120001) sits in the upper third of the sitemap cohort by violation count (172), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (4,535; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 98% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 6 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
