The soil <br /> boring was later used as a percolation test hole, see Plate 1 for the boring location.A groundwater <br /> boring was drilled adjacent to the percolation test boring. <br /> 5.2 Soil Boring Dimensions <br /> ! + The soil boring was approximately three and a half feet deep, as noted above, and was four inches in <br /> + diameter. <br /> Fi 5.3 Soil Lithology Observed <br /> Generally, the soil encountered in the boring is similar to the soil reported by the San Joaquin County <br /> 1 Soil Survey for the area (USDA, 1992).
