1.4.3 Water Sample Location <br /> One domestic well exists on the site. No permits were found during a recent file review at EHD. <br /> A well water sample was taken on December 15, 2008 by Jessen Welch from the domestic well <br /> on the Site. <br /> 1.4.4 Water Sample Constituents <br /> a <br /> The water sample was analyzed for nitrate and DBCP. A sampling Chain-of-Custody is attached <br /> in the appendix. The results of these analyses are forthcoming. <br /> t <br /> I 1.4.5 Well Water Sample Collection, Handling, and Transportation <br /> The sample for nitrate was collected in a clean plastic container; the sample for DBCP was <br /> collected in two clean glass vials. The samples were then transported on ice and remanded <br /> under chain of custody to FGL Environmental, Stockton. <br /> 1.4.6 Chain of Custody <br /> The Chain of Custody document has been included in the appendix of this report. <br /> 1.5 Soil Profile and Geologic Information <br /> The Site is depicted on the California Geologic Survey Map of the San Francisco-San Jose <br /> Quadrangle as within the Quaternary Modesto Formation Upper Member (Qm2), which is <br /> composed of arkosic alluvium forming Mokelumne River terraces and alluvial fans (Plate 5). It <br /> is composed of chiefly sand with minor gravel and silt that is probably glacial outwash material. <br /> The surface and near surface soils located at the Site are reported by the San Joaquin County <br /> Soil Survey to be composed of (101) Acampo sandy loam with 0-2% slopes, and (130) <br /> Columbia fine sandy loam, drained with 0-2% slopes (Plate 6) (USDA, 1992).
