6. u ..r <br /> L December 7,2005 <br /> NOA Project Number: E05141B <br /> A shallow percolation test is defined by the EHD as being between 316/and 42 filches in depth;a <br /> satisfactory percolation rate for a shallow test is less than or qual i X60 ti mutes per inch drop. A <br /> deep percolation test is defined as being between 3.5 `d 25 eet in depth;a satisfactory percolation <br /> rate for a deep test is less than or equal to 30 minutes per inch drop. One percolation test must <br /> demonstrate a satisfactory percolation rate within the proposed septic system disposal field of each <br /> 61 parcel to utilize a standard septic system. Details of the percolation tests are summarized in Table 4. <br /> L Table 4. <br /> Summary of Percolation Tests. <br /> Test No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minutes/inch) Duration (see notes) <br /> P-1 Shallow 3.2 83.3 4 hours Failing percolation rate <br /> P-1 Deep 12.18 4.55 4 hours Satisfactory percolation rate <br /> P-2 Shallow 3.12 35.71 4 hours Satisfactory percolation rate <br /> P-2 Deep 11.62 4.23 4 hours Satisfactory percolation rate <br /> P-3 Shallow 3.12 31.25 4 hours Satisfactory percolation rate <br /> P-3 Deep 15.98 20.83 r 4 hours Satisfacto ercolation tate <br /> Note: A satisfactory percolation rate for a"shallow'test is less than or equal t4 60 minutes per inch.A satisfactory <br /> L percolation rate for a"deep"test is less than or equal to 30 minutes per incl. <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of the site have demonstrate4 a sau f�rcolati <br /> rate in accordance with the requirements of the EHD for the use of a st t atd septic system. <br /> L <br /> 6.8 Discussion of Septic System Sizing <br /> LSeptic System Construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> Standards where applicable. <br /> L <br /> r <br /> L10 <br /> 4 <br />
