What the violations mean
Total Trihalomethanes (TTHMs)
14 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Surface Water Treatment Rule
3 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.
Interim Enhanced Surface Water Treatment Rule
2 incidentsThe system did not meet a filtration or treatment requirement for surface water
Inadequate treatment of surface water can let pathogens such as Cryptosporidium and Giardia through
Haloacetic Acids (HAA5)
1 incidentHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Where the water comes from
Bryan Co. RWS & SWMD #2 draws water from 1 well, 2 surface water intakes and 1 reservoir. It also has an interim connection to Durant Utilities Authority.
Emergency or part-time connections to
- Durant Utilities Authority Durant, OK
Annual water quality report
Bryan Co. RWS & SWMD #2 must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
