Geological rechnics Inc Page 2 <br /> Groundwater Monitoruig Report <br /> Project No 425 2 <br /> Apn1 18,2003 <br /> e All of the deeper screened wells MW-102 MW-105 MW-107 and MW-202) were <br /> p � <br /> non-detect for the event This is the ninth consecutive event that this condition has <br /> ' been documented <br /> ' 1.0 GROUNDWATER MONITORING <br /> 1.1 Hydrology of Site <br /> 1.1.1 Horizontal Groundwater Gradients <br /> The average water table elevation at the site on December 26, 2002, was 73 63 feet above <br /> mean sea level This represents an increase of 0 14 feet since the September 2002 event <br /> ' The water table groundwater gradient was 0 0009 ft/ft flowing NOSE <br /> The average groundwater elevation in the intermediate depth wells (MW-102, MW-105 & <br /> ' MW-107) for the December 2002 monitoring event was 73 52 feet above mean sea level <br /> and the intermediate depth groundwater gradient was 0 0037 ft/ft flowing S62°E <br /> A review of the groundwater gradients shows that the predominant groundwater flow vanes <br /> from north to northeast with the slope ranging from 0 0009 up to 0 0044 ft/ft in the water <br /> ' table wells Table 1 of Appendix A summarizes the water table groundwater gradients and <br /> levels to date, and Figure 2 illustrates the December 26, 2002, groundwater gradient The <br /> predominant groundwater flow is to the east-northeast with the slope ranging from 0 0016 <br /> to 0 0270 ft/ft in the intermediate wells Table 2 of Appendix A summarizes the <br /> intermediate groundwater gradients and levels to date, and Figure 3 illustrate the December <br /> 26, 2002, groundwater direction and gradient in the intermediate wells <br /> ' Table 2 also summarizes the groundwater level data from the deep well, MW-202 <br /> ' The historical water table and intermediate groundwater gradients are included in Figures 4 <br /> & 5- Shallow and Intermediate Rose Diagrams <br /> ' 11.2 Vertical Groundwater Gradients <br /> ' Vertical groundwater gradients were calculated using MW-2/MW-102 <br /> (shallow/intermediate well pair) and MW-102/MW-202 (intermediate/deep well pair) <br /> During the December 2002 event, the vertical groundwater gradient in the <br /> ' shallow/intenmediate well pair was in an upward or positive direction with a magnitude of <br /> 30 7 times that of the water table horizontal gradient The vertical gradient in the <br /> intermediate/deep well pair was upward or positive at a magnitude of approximately 7 6 <br /> times that of the intermediate horizontal gradient <br />
