As required by the laboratory, the sample was collected in a plastic container and three <br /> glass vials for nitrate and DBCP analysis, respectively. The sample was placed on ice <br /> and transported under chain of custody to FGL Environmental, Stockton. <br /> Nitrate was detected in the water sample at a concentration of 6.1 mg/L-N, below the <br /> MCL of 10 mg/L-N. DBCP was detected in the sample at a concentration of 0.07 µg/L, <br /> below the MCL of 0.2 µg/L but over the MCLG of zero. The laboratory analytical results <br /> are attached as Appendix 5 of this report. <br /> Soil Profile and Geologic Information <br /> The Site is depicted on the Preliminary geologic map of the Lodi 30' x 60' quadrangle, <br /> California (Dawson, 2009) as within a map unit of the Modesto formation upper <br /> member, consisting of undivided alluvium (Plate 11). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Acampo sandy loam and Tokay fine sandy loam (USDA, <br /> 2026) (Plate 12). The table below presents some selected properties of these soil <br /> types: <br /> Table 1.

The boring was four inches in diameter, 2.01 feet deep, <br /> and was excavated by hand auger. The location of the boring is indicated on Plate 13. <br /> LOGE 2605 Page 5 <br />
