Pilot Grove PWS standing, mid SDWIS violation third
768 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 15% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #23,093 of 29,740 among systems serving 500+.
The verdict
Pilot Grove PWS lands in the middle third by violation volume (39), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (768; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 15% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.

How many violations vs. how serious, among peer systems
Pilot Grove PWS 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.
