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 prion 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,' ontained in the Appendix. A summary of the percolation test results <br /> is presented next: <br /> Diameter of Depth of <br /> Test No. Hole (in.) Hole (feet) Percolation Rate (min/in) <br /> B1-1 !$ 3.0 240 <br /> BI-2 !'8 22.0 0.3 <br /> B2-1 3.0 320 <br /> B2-2 i 8 25.0 4.3 <br /> B3-1 ,8 3.0 480 <br /> i, <br /> B3-2 ''8 20.0 0.2 <br /> 1 <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 Ibe a minimum of 80 feet long. Proposed systems should be properly <br /> designed and installed according to current San Joaquin County criteria. <br /> to <br /> 7 QE RS ti <br /> y w <br /> O � <br /> 4$SOG� <br /> P <br />
