The verdict
Clarksville Water District lands in the middle third by violation volume (63), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (430; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 5% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.

How many violations vs. how serious, among peer systems
Clarksville Water District 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.
