• May 2007 permit for out-of-service well. A comment at the bottom reads. "Note: Out of service well permit for ag well," though the pump for the domestic well is depicted in the sketch. • September 2018 permit for new irrigation well. The permit notes that the well is 400 feet deep, with a grout seal at 50 feet. These documents have been included in Appendix 4 of this report. Water Sample The domestic well on the Site is not yet operable. No water sample was collected. Soil Profile and Geologic Information The Site is mapped on the Preliminary geologic map of Cenozoic deposits of the Bellota quadrangle, California (Marchand, D.E., and Bartow, J.A., 1979). It is depicted within a map unit of the Riverbank formation middle unit, defined as "arkosic alluvium forming Mokelumne River terraces and alluvial fan; chiefly sand; probably glacial outwash" (Plate 9). The surface and near surface soils located at the Site are reported by the USDA Web Soil Survey to be composed of Bruella sandy loam, hard substratum, and San Joaquin loam (Plate 10) (USDA, 2020). The table below presents some selected properties of these soils: Table 1.
