What the violations mean
Groundwater Rule
1 incidentThe 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 this violation.
Where the water comes from
Jade MHC draws water from 2 wells (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Jade MHC 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 Jade MHC for a copy.
