What the violations mean
Long Term 2 Enhanced Surface Water Treatment Rule
27 incidentsThe system failed required surface water treatment or filtration standards
Untreated or inadequately treated surface water can contain bacteria and viruses
Total Trihalomethanes (TTHMs)
8 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Surface Water Treatment Rule
4 incidentsThe system did not complete a treatment step or action that the Surface Water Treatment Rule requires (a treatment technique violation).
The utility had to notify customers about each of these violations.
