Under natural conditions, water levels in wells completed in many confined aquifers rise above the land surface, resulting in artesian flow. The well shown in the photograph was drilled near Franklin, Virginia, in 1941 to a depth of about 600 feet in confined aquifers. The initial water level in the well was about 7 feet above land surface.
