What the violations mean

Haloacetic Acids (HAA5)

18 incidents

Haloacetic acid byproducts exceeded the federal limit

Long-term exposure to HAAs may increase cancer risk

Total Trihalomethanes (TTHMs)

10 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

Interim Enhanced Surface Water Treatment Rule

8 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

Surface Water Treatment Rule

3 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.

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

Hydaburg draws water from 1 surface water intake.

Annual water quality report

Hydaburg 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 Hydaburg for a copy.

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 Alaska.
