1 <br /> 1 <br /> Greer Proer <br /> p ty <br />' 15634 Steinegul Road, Escalon, California <br />' Quarterly Groundwater Sampling Report <br /> First Quarter, 2001 <br /> I <br /> Narrative <br />' On March 8, 2001, VVBF, Inc., conducted field measurements, well pumping and <br /> groundwater samphng at nine (9) groundwater monitoring wells and one (1) domestic well <br />' located at this site (Figure 1 & 2). <br /> Groundwater elevations were taken from nine (9) wells prior to pumping (Table 1 & <br /> I Appendix B). Monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-8, <br /> MW-9 and MW-10 were evacuated by means of a steam-cleaned, stainless steel bladder <br /> type pump Each well was sampled with a disposable bailer During the stabilization <br /> process for each well, samples were collected to measure field pH, electrical conductivity <br /> and temperature (Table 3, Appendix B) Once stability was achieved, the samples were <br /> collected for laboratory analysis The samples were then labeled and placed in an ice chest <br /> cooled with Blue Ice®. <br /> The samples were then logged on a Chain of Custody and transported to GeoAnalytical <br /> Laboratories, Inc , in Modesto, California for analysis (Appendix A) The analyses <br /> requested for the water samples was EPA method 8021B for BTX&E (Benzene, Toluene, <br /> Xylene, and Ethyl-Benzene), and EPA method (5030/Luft) for gasoline MTBE (Methyl <br /> Tertiary Butyl Ether),concentrations were analyzed by EPA method 8260B The analytes <br /> and concentrations detected are listed in Table 2 of this report. The laboratory analytical <br /> data, chain of custody report, and QA/QC documents can be found in Appendix A of this <br /> report. <br /> Groundwater Gradient <br /> Ile Groundwater elevations are referenced in Table 1 of this report. During tins quarter the <br /> groundwater gradient flowed in a southeast direction (S35°E) at 0 0210 ft/ft at (Figure 3) <br /> I <br />
