Groundwater and Aquifers FAQs - 21 Found
Artesian well water is water from a well that taps an aquifer that is 'confined'. This aquifer is water-bearing rock below ground that is surrounded by other rock or material that does not allow water to pass through. So, the water in this aquifer is squeezed by the other rocks, creating pressure in the water-bearing aquifer. When an artesian aquifer is tapped by a well the pressure pushes the water up the well, sometimes all the way to the surface, creating a flowing well. Imagine it as a very wet sponge contained in a closed plastic bag. Put a straw through the bag into the sponge, hold the bag tightly around the straw, and SQUEEZE - that would be artesian water squirting you in the face.
