What the violations mean
Groundwater Rule
2 incidentsThe 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
Sky Hi DWID draws water from 3 wells.
Annual water quality report
Sky Hi DWID 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 Sky Hi DWID for a copy.
