What the violations mean

Lead and Copper Rule

2 incidents

The system did not complete a treatment step or action that the Lead and Copper Rule requires (a treatment technique violation).

The utility had to notify customers about each of these violations.

Where the water comes from

Welches Water Company draws water from 2 springs.

Annual water quality report

Welches Water Company 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 Welches Water Company for a copy.

Find a posted report with EPA's Consumer Confidence Report search

Testing your own water

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