What the violations mean
Interim Enhanced Surface Water Treatment Rule

Inadequate treatment of surface water can let pathogens such as Cryptosporidium and Giardia through
Surface Water Treatment Rule
25 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.
Total Trihalomethanes (TTHMs)
25 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
CARBON, TOTAL
11 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.
Haloacetic Acids (HAA5)
9 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Revised Total Coliform Rule
1 incidentThe system did not meet a requirement of the Revised Total Coliform Rule
Coliform and E. coli rules protect against bacteria in the distribution system
Where the water comes from
Sardis Lake Water Authority draws water from 1 surface water intake. 4 other community water systems buy water from Sardis Lake Water Authority.
Community systems that buy water from it
- Clayton PWA Clayton, OK
- Latimer Co. RWD #2 Talihina, OK
- Pushmataha Co. RWD #1 Clayton, OK
- Pushmataha Co. RWD #5 (Nashoba) Nashoba, OK
Annual water quality report
Sardis Lake Water 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.
Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Sardis Lake Water Authority for a copy.
Find a posted report with EPA's Consumer Confidence Report search
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.
Certified drinking water labs by state EPA guidance for private wells
