Where the water comes from

Sundance Improvement Association draws water from 3 wells (1 of them for emergency, seasonal or other part-time use).

Annual water quality report

Sundance Improvement Association 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 Sundance Improvement Association 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 Washington.
