Bay Harbor Islands Town Of standing, low SDWIS violation third

26% of 19 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 26% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #6,816 of 29,740 among systems serving 500+.

The verdict

Bay Harbor Islands Town Of is in the lower third by violation count (19; lower-third violation load (≤ 21 violations)). A low count does not mean the system is unmonitored - monitoring and reporting violations still appear in SDWIS. Population served is large (6,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 26% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
