The Springs: A Scientific Explanation
A mineral-rich natural reservoir deep underground produces Saratoga’s spring waters.
Local geology has created the only active carbonated mineral springs east of the Mississippi River. Several layers of limestone lie beneath the region’s topmost layer of shale bedrock. As deep underground water percolates through the limestone layers, it dissolves and absorbs some of the minerals from the rock. This explains the high mineral content found in the spring water.
Charged with carbon dioxide, the water forces its way up through faults, or cracks, in the shale bedrock, creating Saratoga’s springs.
This area’s shale bedrock separates the deep mineral water from the shallow groundwater that lies very close to the surface. Scientists have offered a number of explanations for how the reservoir is supplied, but no definitive answer to this question has yet emerged. Scientists agree, however, that all of Saratoga’s springs are fed by a single, interconnected reservoir network. This finding helped lay the legal foundation for the Saratoga Reservation that protects the springs.
