The Crystalline Bedrock Aquifer

The crystalline bedrock aquifer is made up of a granite-type crystalline structure. This formation has the following characteristics:

• It was formed 600 million to 4,000 million years ago,
• It exists below the other aquifers throughout the entire state

As with the Eastern Dolomite Aquifer, the amount of water that can be obtained from a well drilled into the crystalline bedrock aquifer is largely dependent on the cracks and crevasses it intersects.
