What the violations mean
Total Trihalomethanes (TTHMs)
52 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Interim Enhanced Surface Water Treatment Rule

Inadequate treatment of surface water can let pathogens such as Cryptosporidium and Giardia through
CARBON, TOTAL
14 incidentsThe system did not complete a treatment step or action that federal rules require for CARBON, TOTAL (a treatment technique violation).
The utility had to notify customers about each of these violations.
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).

Where the water comes from
Wewoka Public Works Authority draws water from 1 surface water intake. 3 other community water systems buy water from Wewoka Public Works Authority.
Community systems that buy water from it
- Hughes Co. RWD #5 Holdenville, OK
- Seminole Co. RWD #1 Wewoka, OK
- Seminole Co. RWD #2 Wewoka, OK
Annual water quality report
Wewoka Public Works Authority 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.

Testing your own water
To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Oklahoma.
