City of Bossier City Water System standing, low SDWIS violation third
67% of 15 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 67% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #661 of 29,740 among systems serving 500+.
The verdict
City of Bossier City Water System is in the lower third by violation count (15; 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 (78,960; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 67% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.

How many violations vs. how serious, among peer systems
City of Bossier City Water System plotted against 29 peer public water systems (500+ people served), by total violation count (x) and the share of those violations that are health-based (y). The crosshair sits at this sample's own median on each axis. A high violation count does not automatically mean a serious record: most monitoring and reporting violations are minor, not health-based.
