What the violations mean
Haloacetic Acids (HAA5)
4 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Where the water comes from
Port Alexander PWS draws water from 2 surface water intakes (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Port Alexander PWS 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 Port Alexander PWS 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 Alaska.
