The table below presents the soil log for the <br /> groundwater boring. Conditions were comparable in both shallow holes. <br /> Table 2 <br /> Soil Boring Log <br /> Depth Interval (ft) Soil Type unified Soil Classification <br /> 0 - 8.5 Medium brown, sandy silt SM <br /> 5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates potential for percolation because of <br /> the nature of the soils. A percolation test is the best method to determine the suitability of the <br /> soils for a septic disposal area. Please see the next section for percolation test results. <br /> Generally speaking, coarser-grained soils have much greater potential for percolation than fine- <br /> grained or cemented soils. <br /> 6.0 PERCOLATION TEST INFORMATION <br /> 6.1 Percolation Test Locations <br /> A site map indicating the locations of the percolation test holes is included as Plate in the <br /> appendix of this report. <br /> 6.2 Number of Percolation Tests <br /> One (1) shallow test was conducted on each parcel for a total of two (2) shallo percolation <br /> tests conducted on the property. <br />~ 6.3 Boring Preparation and Presaturation <br /> The soil borings were advanced on the property with a hand auger on July 10, 2008. <br /> A 1.5-inch in diameter PVC pipe with perforations on the bottom was used to measure the drop <br /> of water in the percolation test boring. Approximately 2 inches of "pea gravel" was placed in <br /> the bottom of the open soil boring and the PVC pipe was then installed on top of the gravel. <br /> "Pea gravel"was then used to backfill the annular space. <br /> Presaturation of the percolation test holes occurred approximately 24 hours prior to the day of / <br /> testing. The depth of water used to pre-soak was twelve (12) inches above the bottom of the <br /> boring. <br /> ,44 <br /> 902 Industrial Way• Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 ('2008 Nei/O.Anderson&Associates.Inc <br />
