This <br /> was done so that the ground water table gradient could be <br /> determined. The writer constructed three point diagrams to j <br /> determine the groundwater gradient at this site. Diagrams were <br /> constructed to determine site conditions on 12/03 and 12/21/87. <br /> Diagrams were not constructed for conditions on 11/05/87 because <br /> the aquifer , had not had time to recover from drilling <br /> disturbance, so precise water table measurements were not <br /> possible. <br /> The graphic solution of the three point problems is shown on <br /> t`:e accompanying work.sheets.This analysis shows that the ground <br /> water tab1E gradient is to the northwest at 0. 14 ft. of drop <br /> 7Pr 100 ft. of plan distance, on 12/03/87. The ground water <br /> _,.'ila gradient has changed to the northeast at 0. 25 ft. of drop . <br /> per 100 ft. of pian distance on 12/21/87. This is probably <br /> dire to increased recharge coming into the ground water system <br /> from the west of the site <br /> Th= above represents my best professional opinion as to :`:•e <br /> urfi c:al geologic and shallow ground water conditi.nr:s <br /> t!r- l � `_tr <br /> e is site.
