The system did not complete a treatment step or action that the Groundwater Rule requires (a treatment technique violation).

The utility had to notify customers about each of these violations.

Where the water comes from

Tanacross Water System draws water from 1 well.

Annual water quality report

Tanacross Water System 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 Tanacross Water System 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.
