Due to the height of ground water in the area <br /> recommended systems should include shallow leach lines only. If the proposed septic system is <br /> not in the general area of our percolation tests, an additional test may need to be performed. Any <br /> proposed system should be properly designed and installed according to current San Joaquin <br /> County criteria. <br /> If the county minimum separation between the bottom of the leach lines and ground water <br /> is maintained and based on the size of the proposed lots, it is our opinion that the installation of <br /> the proposed septic system, if properly installed, should not adversely affect the quality of the <br /> ground water in the area. <br /> r PERS o <br /> D �+ <br /> Z W <br /> O � <br /> 4ssor� <br /> P <br />
