Ground water beneath the facility is roughly 59 feet below ground surface. <br /> The water table has dropped almost 16 feet from December 1985 to <br /> December 1991 . The ground water flow direction in the first water bearing <br /> zone has varied over the last six years. However, it is generally in a <br /> southwatereinyto San Joaquinsterly County dare municipale beneficial and domestic,uses of theirrigation,9round <br /> stock <br /> watering, process and service supply. <br /> 4.
