Consumer Confidence Reports

The federal CCR rule requires all community water systems (CWS) to provide annual drinking water quality reports to their customers by July 1st.  CWS’s that serve more than 500 but less than 10,000 persons are required to publish their report in one or more local newspapers.  The Big Sky Water & Sewer District fits into this category, so the CCR is published in the Lone Peak Lookout each year.  Click the links above to view the CCR’s for the District’s water system for past years.  The office also has hard copies available upon request.

Each CCR has a summary table for each permitted public water system which includes- Aspen Groves, the Meadow Village and Mountain Village Water systems.  For more information about the CCR visit the EPA website below:
