j NLS§ 2.2, 3.1, SSS§ 2.1, 4.2. Since surrounding properties have been intensely farmed for several <br /> V decades, the potential for nitrate contamination in the underlying shallow groundwater aquifers is <br /> significant. This is illustrated in the original (old) well analyses, found in Appendix E, and <br /> summarized below in Table 3. The nitrate and DBCP concentrations were over the Maximum <br /> Contamination Levels (MCL). However, well water obtained from the new well indicate no DBCP <br /> or nitrate concentrations. This may be attributed to sufficient intervening clay layers attenuating the <br /> downward migration of nitrate and DBCP, and sufficient denitrification potential within the <br /> underlying aquifers, as referenced above. <br /> ✓ NLS§ 2.3, SSS§ 4.3, 4.4, 4.5. On October 12, 2007, the new domestic well was sampled under <br /> the following procedures: The well was pumped for one-half hour and cycled five times. <br /> Consequently, aquifer water and not stagnant well water was sampled. Well water was sampled <br /> from a sampling port on top of the discharge pipe from the well casing. A one pint plastic bottle <br /> was used for the nitrate analysis, a 100 ml plastic bottle was used for the bacteriological sample, <br /> and two VOA vials with preservative for DBCP analysis. <br /> After sampling, the sample bottles were placed in a cooled ice chest after sampling, and then <br /> transported to FGL Environmental Laboratory in Stockton under the attached Chain of Custody. <br /> As referenced, the constituents tested were for nitrate, bacteriological (Total and Fecal Coliform), <br /> and DBCP. The recently drilled new well yielded the findings that are found in Appendix F. The <br /> following Table summarizes and illustrates the test results: <br /> TABLE 3 <br /> UNDERLYING GROUNDWATER ANALYSIS FROM THE ORIGINAL OLD WELL <br /> AND THE RECENTLY DRILLED NEW ON-SITE DOMESTIC WELL <br /> ANALYTE NEW WELL ORIGINAL OLD WELL <br /> Nitrate ND 76.1 mg/L(45 mg/L=MCL) <br /> No ct <br /> DBCP ND 0.41 gg/L(0.2 gg/L=MCL)Noll <br /> Detect <br /> Bacteriological: Fecal: Absent <br /> Total and Fecal Coliform Total: Present Not Tested-Well Destroyed <br /> October 12,2007 Analysis <br /> Bacteriological: Fecal: Absent <br /> Total and Fecal Coliform Total: Present Not Tested-Well Destroyed <br /> October 29,2007 Analysis <br /> Bacteriological: Fecal: Absent <br /> Total and Fecal Coliform Total: Present Not Tested-Well Destroyed <br /> November 6, 2007 Analysis <br /> Bacteriological: Fecal: Not Analyzed <br /> Total Coliform Total: Absent Not Tested-Well Destroyed <br /> December 4, 2007 Analysis <br /> 5 <br /> Chesney Consulting <br />
