What the violations mean

Groundwater Rule

7 incidents

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

White Swan draws water from 6 wells.

Annual water quality report

White Swan 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 EPA Region 10.
