The water held in these spaces is under pressure because of the weight of water in the portion of the aquifer above it. If a well is drilled from the land surface through the overlying impervious layer into the aquifer, this pressure will cause the water to rise in the well.
In areas where the slope of the aquifer is great enough, pressure will drive the water above ground level in a spectacular, permanent fountain.
Artesian springs can occur in similar fashion where faults or cracks in the overlying impervious layer allow water to flow upward.
Water from an artesian well or spring is usually cold and free of organic contaminants, making it desirable for drinking.”
