A further 14 monitoring and reporting violations are on file. The most recent violation on record dates to 2023.
The most frequently cited contaminant at this system is TTHM, recorded in 4 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 4.7 ppt (parts per trillion). PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.
Across Tennessee, EPA tracks 762 public water systems serving 7,934,203 people, with 43,318 cumulative violations and 9,414 health-based violations on record. About 94% of systems in the state carry at least one violation, and state-wide the average per system is 56.8 violations.
