(Condor) conducted annual domestic wastewater <br /> monitoring activities at the above-referenced Site. Data are provided in compliance with.Monitoring and <br /> Reporting Program (MRP) Board Order No. R5-2002-0034 dated March 7, 2002. Three domestic <br /> wastewater monitoring wells identified as DWS-1, DWS-2, and DWS-3 were installed by requirement of <br /> the SJCEHD to monitor groundwater quality .in the vicinity of the on-Site septic leachfield. Annual <br /> monitoring of these wells is-required by the MRP due to shallow groundwater conditions at the Site. <br /> Figures indicating the Site location, monitoring well locations, and groundwater elevation contours <br /> (Figures 1, 2,-and 3, respectively) are attached to this report. Also attached are field forms, historic <br /> groundwater monitoring data, and laboratory analytical results. . <br /> SAMPLING PROCEDURES AND FIELD OBSERVATIONS <br /> On May 9, 2006, a Condor representative measured water levels in the 10 on-Site monitoring wells and <br /> collected groundwater samples from the three domestic wastewatermonitoring wells. All down-hole field <br /> equipment was decontaminated in the field with a solution of laboratory-grade, non-phosphate detergent <br /> and deionized water and rinsed with deionized water prior to use in each well. All field instruments were <br /> calibrated to manufacturer-recommended standards.The water level'in each well was measured to the <br /> nearest 0.01 foot with a battery-operated, flat-tape, water-level meter. A new, disposable, polyethylene <br /> bailer was lowered into each well to collect a field inspection sample. The bailer samples were inspected <br /> for discoloration and odor. No odors were noted in the groundwater purged from the wells. The wells <br /> were purged with new, disposable, polyethylene bailers until at least three well-casing volumes of water <br /> were removed and the electrical conductivity (EC), pH, and temperature of the water stabilized. The <br /> groundwater purged from the wells was discharged to the ground surface. Field forms completed for the <br /> work are attached. <br /> The groundwater samples were collected by filling laboratory-supplied containers with groundwater <br /> directly from the disposable bailers. The sample containers were labeled, placed in a cooler chilled with <br /> �� colvooR <br />
