Arrowhead is a spring water brand bottled from multiple sources. The 2025 water analysis report lists springs in California (including Arrowhead Spring in San Bernardino County), Colorado, Oregon and Arizona, and Hope Springs in British Columbia, Canada. As of October 2026 the brand belongs to Primo Brands Corporation, formed in November 2024 by the merger of Primo Water and BlueTriton Brands; labels and analysis reports are still issued in the name of BlueTriton Brands, Inc., which acquired Arrowhead from Nestlé Waters North America in 2021.
