For approximate location of the percolation tests see the <br /> Location Map in the Appendix. <br /> The percolation tests were performed in 8 inch diameter test holes. For the shallow <br /> tests, a 3 inch diameter perforated pipe measuring device was placed in each test hole and <br /> backfilled with 3/4 inch gravel. For the deep pit tests, a 4 inch diameter perforated pipe <br /> was placed in each hole and backfilled with 3/4 inch gravel. All test holes were filled with <br /> water 24 hours prior to running the tests. The last ten minutes or 30 minutes (whichever <br /> applied) of the test readings were witnessed by a San Joaquin County health official and the <br /> test data obtained is contained in the Appendix. A summary of the percolation test results <br /> is presented next: <br /> Diameter of Depth of <br /> Test No: Hol in Hole (feet)- Percolation R in in <br /> B1-1 8 3.0 ' 240 . <br /> ;I <br /> B1-2 8 X2.0 - - - 0.3 i <br /> B2-1 8° 3.0 ` 320 ; <br /> B2-2 8 425.0 4.3 <br /> B3-1 81 3.0 <br /> B3-2 8 20.0 .. 0.2 <br /> a <br /> VII CONCLUSION <br /> Based on the' results of the percolation tests, the soil profile, and the past <br /> performance of the existing septic systems on and around the surrounding property, it is our <br /> opinion that the subject property should be suitable for construction of typical on-site <br /> sewage disposal systems. Where cemented surface soils exist, these systems should consist <br /> of a septic tank, leach. field, and dry wells. It is recommended that leach lines terminating <br /> in a dry well should be a minimum of 80 feet long. Proposed systems should be property <br /> designed and installed according to current San Joaquin County criteria. <br /> �oesso� <br /> N <br /> � w <br /> 9SS 0GS <br /> P <br />
