Where the water comes from

EPA lists groundwater as the main source for Bella Vista Water Sys but has no individual wells or intakes on record.

Annual water quality report

Bella Vista Water Sys 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 Bella Vista Water Sys for a copy.

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 California.
