Cold Spring Minearal Water is filled at the source from a pure protected underground glacial lake. Twelve thousand years ago as the glaciers retreated, mammoth Lake Agassiz was formed in Minnesota and central Canada. Throughout the ages water percolated down into the deep crystalline granit reservoirs of central Minnesota creating unusually pure water. Filtered by nature and untouched by modern civilization, we invite you to experience the healthy refreshment that the glaciers left behind.
