Bostwick Lake Inn standing, mid SDWIS violation third

100% of 23 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 100% is upper-third health share (> 23%). Population rank #25,921 of 29,740 among systems serving 500+.

The verdict

Bostwick Lake Inn lands in the middle third by violation volume (23), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (612; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 100% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
