kn K L E I N F E L D E R <br /> i <br /> 5 MONITORING RESULTS <br /> i - <br /> The depth to groundwater was measured in each monitoring well included in this event. The <br /> depth to groundwater data was converted to elevation in reference to mean sea level for the <br /> calculation of groundwater flow direction and gradient. <br /> The 6 groundwater samples were submitted under chain-of-custody procedures to Sequoia <br /> 1 Analytical Laboratories of Sacramento, California. Table 2 is a summary of the analytical results <br /> 3 for groundwater. For a complete report of the analytical results please refer to the chain-of- <br /> custody forms and laboratory analytical reports included.in Appendix C. <br /> 5.1. WATER LEVELS <br /> On December 6, 2002, all 20 monitoring wells and three piezometers were sounded for depth to <br /> groundwater. On December 9, 2002 six monitoring wells were sampled. The depth to <br /> groundwater ranged from 44.51 feet below the top of well casing (T.O.C.) to 53.60 feet below <br /> T.O.C. <br /> The groundwater elevations ranged from —33.54 feet msl.to —34.19 feet msl at the site. The <br /> groundwater gradient was calculated to be relatively flat at 0.0005 feet/foot, and a general <br /> direction of flow to the southeast. Plate 3 shows the interpreted groundwater contours. The <br /> reported groundwater flow direction has been consistent with the historical data collected at the <br /> site. Please refer to Table 1 for the recorded groundwater elevations on December 6, 2002 and <br /> past monitoring events. <br /> f <br /> 12280.MON/ST03R225 Page 8 of 12 <br /> '2003,Kleinfelder,Inc February 5,2003 <br />
