" <br /> <br />Under natural conditions, water levels in wells completed in many <br />confined aquifers rise above the land surface, resulting in artesian <br />flow. The well shown in the photograph was drilled near Franklin, <br />Virginia, in 1941 to a depth of about 600 feet in confined aquifers. <br />The initial water level in the well was about 7 feet above land surface. <br />The above-ground structure shown in the photograph (Cederstrom, <br />1945) was built in the 1940's as a creative solution to measure the <br />water level in this well. Measurements at the well were discontinued <br />in 1960. Today, measurements at other nearby wells indicate that <br />water levels are now 150 to more than 200 feet below land surface. <br />
