Where does Pure Flo water come from?
The Pure Flo Deep Well source is a 910 foot well at our bottling facility at the base of Cowles Mountain in Santee. The well source is stainless steel encased to a depth of 900 feet.
How often is Pure Flo water tested?
Pure Flo is tested by our own quality assurance personnel on an hourly basis. A weekly test of each product is sent to a California State approved independent laboratory for further testing.
