100% Natural Spring Water…And Proud of It. A lot has changed since we got our start in 1845, but at least one thing remains the same: Poland Spring Brand 100% Natural Spring Water is still sourced from our carefully selected springs in Maine. Helping Keep Maine Beautiful We treat each spring source with the great care and respect it deserves. Springs are regularly monitored by our natural resource managers and field experts for quality and sustainability. We’re proud to share their hard work. What Is Spring Water Anyway? Great question. According to the U.S. Food & Drug Administration (FDA): “Spring Water is water derived from an underground formation from which water flows naturally to the surface of the earth at an identified location.” To be able to label our product as “spring water,” we have to satisfy stringent standards — standards we proudly meet or exceed. That’s why every bottle of Poland Spring Brand water is labeled as 100% natural.
