LNovember 29, 2005 <br /> NOA Project Number: E05003B <br /> ` suitability of the soils for a septic disposal field. Please see the next section for percolation test <br /> results. Generally speaking, sandy soils have much greater potential for percolation than fine- <br /> grained or cemented soils. <br /> 6.0 PERCOLATION TEST INFORMATION <br /> L6.1 Percolation Test Locations <br /> LA site map indicating the location of the percolation test hole is included as Plate 1 in the appendix 6 <br /> of this report. <br /> L6.2 Number of Percolation Tests <br /> One shallow percolation test was conducted on the proposed parcel of the Site, for a total of one <br /> Lshallow percolation test <br /> L6.3 Boring Preparation and Presaturation <br /> A total of one shallow soil boring was advanced on the Site with a four inch diameter hand auger on <br /> LNovember 16, 2005. <br /> A 1.5-inch diameter PVC pipe with perforations on the bottom was used to measure the drop of <br /> water in the percolation test boring. Approximately 2 inches of"pea gravel" were placed in the <br /> bottom of the open soil boring,then the PVC pipe was installed on top of the gravel. "Pea gravel' <br /> was backfilled in the annular space. <br /> LPresaturation of the percolation test hole occurred on November 16,2005.The depth of water used <br /> to pre-soak was 12 inches above the bottom of the boring. <br /> 6.4 Condition of Borings After Presaturation <br /> L <br /> After the 24-hour soak period,the presaturated hole was found to be intact and dry on the day of y <br /> Ltesting. <br /> 6.5 Percolation Test Procedure <br /> I <br /> A percolation test was conducted for the boring on November 16, 2005, in accordance with the <br /> requirements of the EHD. A percolation test with a duration of four hours was performed for the 7 <br /> ` hole. The last half an hour of the four test was observed by Mr.Ted Tasiopoulas, Registered <br /> 1• Environmental Health Specialist, EHD. <br /> 8 <br /> L -44 <br /> L <br />
