Bayleaf Master standing, high SDWIS violation third
29% of 415 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 #3,350 of 29,740 among systems serving 500+.
The verdict
Bayleaf Master sits in the upper third of the sitemap cohort by violation count (415), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (15,585; 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 9 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
