The Water Loft Premium Spring Water is a natural resource from springs located atop Palomar Mountain in Southern California. Our pure spring water source is high on the mountain above the smog level and miles away from any Gasoline station and an analysis by a State Certified Laboratory prove that our source water complies with all of the requirements of California Proposition 65, the Food and Drug Administration (FDA), the National Sanitation Foundation (NSF), and the International Bottled Water Association (IBWA). The source water is free of MTBE and any other Synthetic Organic Chemicals. Our water goes down smooth and is extremely refreshing!
