Groundwater Rule

2 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

Dillingham Water System draws water from 3 wells. 1 other public water system has a seasonal connection to Dillingham Water System.

Annual water quality report

Dillingham 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.

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.
