Tennessee American Water standing, low SDWIS violation third
UCMR5 detected 2 PFAS compounds - lower-third PFAS panel (≤ 2 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #195 of 29,740 among systems serving 500+.
The verdict
Tennessee American Water is in the lower third by violation count (0; 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 (211,499; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. No violations are on record in this extract. UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).

Violation Count vs. the National Corpus
Tennessee American Water has 0 recorded EPA violations, 0% of the 29,740 public water systems serving 500+ people nationwide carry fewer, and 96% carry more. 0% of this system's own violations are health-based (0 of 0), and it ranks #195 of 29,740 by population served among that same cohort.

How many violations vs. how serious, among peer systems
Tennessee American Water 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.
