Equipment Company <br /> 1245 West Charter Way <br /> Stockton, California <br /> Project No 507 2 <br /> July 28, 2000 <br />�. EXECUTIVE SUMMARY <br /> This report summarizes the 2"d Quarter 2000 round of groundwater monitoring and testing <br /> that took place on June 16, 2000 The analytical results of groundwater samples show that <br /> detectable concentrations of BTEX and TPH-G were present in five of eight groundwater <br />' monitoring wells The fuel oxygenate compound MTBE was detected in two of the eight <br /> wells, and the concentrations detected had increased since the March 8, 2000 sampling event <br />' On June 16, the average depth to groundwater at the site was 13 07 bgs and the groundwater <br /> flow was N6°W at 0 0005 ft/ft <br />' 1.0 GROUNDWATER MONITORING <br /> 1.1 Hydrogeology of Site <br />' The geology of the site is predominately clays and sandy clays with lesser amounts of silts <br /> and sands The average groundwater elevation was 5 60 feet below MSL on June 16, 2000 <br />' MSL is approximately 7 37 feet below ground surface <br />' A groundwater gradient was calculated for the event and found to be flowing N6°W at <br /> 0 0005 ft/ft Gradient direction for the monitoring event 2s shown in Figure 2 The <br /> . groundwater elevation data is summarized in Table 1, Appendix A <br />
