What the violations mean
Surface Water Treatment Rule
9 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
Riverview CG draws water from 1 surface water intake.
Annual water quality report
Riverview CG 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 Riverview CG for a copy.
