What the violations mean
Haloacetic Acids (HAA5)
4 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
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
Total Trihalomethanes (TTHMs)
1 incidentDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
LEAD AND COPPER RULE REVISIONS
1 incidentThe 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.
Where the water comes from
Creek Co RWD # 7 draws water from 1 surface water intake. It also has an emergency connection to Creek Co RWD # 2.
Emergency or part-time connections to
- Creek Co RWD # 2 Jenks, OK
Annual water quality report
Creek Co RWD # 7 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.
