What the violations mean
Groundwater Rule
12 incidentsThe system did not complete a treatment step or action that the Groundwater Rule requires (a treatment technique violation).

Where the water comes from

Annual water quality report
Cobbs Lake Preserve 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 Cobbs Lake Preserve for a copy.
