What the violations mean

Groundwater Rule

2 incidents

The 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

Cochiti Lake draws water from 4 wells (2 of them for emergency, seasonal or other part-time use).

Annual water quality report

Cochiti Lake 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 Cochiti Lake for a copy.

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by EPA Region 6.
