Generally speaking, coarse-grained soil has a greater potential for percolation �7 <br /> than fine-grained or cemented soil. <br /> 1.6 Percolation Test Information <br /> 1.6.1 Percolation Test Locations <br /> A site map indicating the location of the percolation test hole is included as Plate 1 in Appendix •I' <br /> A of this report. <br /> 1.6.2 Number of Percolation Tests <br /> One percolation test, at 3.25 feet bgs (P1), was conducted on the project site (within the <br /> existing septic leach field area). P1 was recorded for county review, which is discussed in more <br /> detail below. The percolation test was performed for soil characterization to validate the <br /> adequacy of the existing on-site septic field. <br /> 1.6.3 Boris Preparation and Presaturation <br /> The soil boring was advanced on the subject property with a four inch hand auger on February <br /> 18, 2015. Approximately two (2) inches of "pea gravel" were placed in the bottom of the open <br /> soil borings, then 2.0-inch diameter PVC pipe with perforations on the bottom was installed on <br /> top of the gravel in the boring. "Pea gravel" was then used to backfill in the annular space. <br /> Presaturation of the percolation test hole occurred approximately 24 hours prior to the day of <br /> testing (February 19, 2015). The depth of water used to pre-soak was 36 inches above the <br /> bottom of the boring. <br /> 1.6.4 Condition of Borings after Presaturation <br /> After the 24-hour soak period, the presaturated hole was found to be intact and dry on the day <br /> of testing (February 19, 2015). <br /> 1.6.5 Percolation Test Procedure <br /> ..44 <br /> ©2015 Neil O.Anderson&Associates,Inc. <br /> A Terracon Company <br /> i <br />
