Battle Creek Water Supply standing, high SDWIS violation third
43% of 142 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 43% is upper-third health share (> 23%). Population rank #24,279 of 29,740 among systems serving 500+.
The verdict
Battle Creek Water Supply sits in the upper third of the sitemap cohort by violation count (142), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (700; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 43% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.

How many violations vs. how serious, among peer systems
Battle Creek Water Supply 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.
