What the violations mean

Surface Water Treatment Rule

63 incidents

The 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)

60 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

Haloacetic Acids (HAA5)

28 incidents

Haloacetic acid byproducts exceeded the federal limit

Long-term exposure to HAAs may increase cancer risk

Interim Enhanced Surface Water Treatment Rule

23 incidents

The 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

CARBON, TOTAL

22 incidents

The 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.

LEAD AND COPPER RULE REVISIONS

1 incident

The system did not complete a treatment step or action that the LEAD AND COPPER RULE REVISIONS requires (a treatment technique violation).

The utility had to notify customers about this violation.

Revised Total Coliform Rule

1 incident

The 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

Hominy draws water from 1 surface water intake. 1 smaller public system such as schools, businesses or campgrounds buys water from Hominy.

Annual water quality report

Hominy 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.

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.
