• August 2005 permit for out-of-service well. The permit notes that the house is <br /> being demolished. <br /> These permits have been included in Appendix 4 of this report. <br /> Water Sample <br /> There is currently no operational well on the Site. No water sample was collected as <br /> part of this investigation. <br /> Soil Profile and Geologic Information <br /> The Site is depicted on the Preliminary geologic map of Cenozoic deposits of the <br /> Bellota quadrangle, California (Marchand and Bartow, 1979). The Site is depicted <br /> within a map unit of the Riverbank formation upper unit, described as "arkosic alluvium <br /> forming Mokelumne River terraces and alluvial fan; chiefly sand; probably glacial <br /> outwash" (Plate 8). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of San Joaquin loam, thick surface (Plate 9) (USDA, 2020). <br /> The table below presents some selected properties of this soil: <br /> Table 1.

See description of the map unit for <br /> composition and behavior characteristics of the map unit. <br /> Soil Borings <br /> On September 8, 2020, Live Oak observed the drilling of shallow and deep percolation <br /> test borings by Central Valley Septic Services. The borings were 12 inches in <br /> diameter, 3.25 and 25.11 feet deep, and were drilled with a Spiradrill LHD 50 (Table 2). <br /> The location of the borings is indicated on Plate 10. Because of the parcel size and <br /> location of existing wells on adjacent parcels, Mr. and Mrs. Nienhuis obtained <br /> permission from Wayne Fox, REHS, Interim Director of the San Joaquin County <br /> LOGE 20-41 Page 4 <br />
