6 incidents

The system failed required surface water treatment or filtration standards

Untreated or inadequately treated surface water can contain bacteria and viruses

Revised Total Coliform Rule

1 incident

Annual water quality report

Grand Portage 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
