What the violations mean
Surface Water Treatment Rule
17 incidentsThe system did not complete a treatment step or action that the Surface Water Treatment Rule requires (a treatment technique violation).
The utility had to notify customers about each of these violations.
Where the water comes from
Old Harbor draws water from 1 infiltration gallery.
Annual water quality report
Old Harbor 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 Old Harbor for a copy.
