What the violations mean

Haloacetic Acids (HAA5)

33 incidents

Haloacetic acid byproducts exceeded the federal limit

Long-term exposure to HAAs may increase cancer risk

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.

Where the water comes from

Klawock draws water from 1 surface water intake.

Annual water quality report

Klawock 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 Alaska.
