ASSURED INSPECTION MANAGEMENT <br /> AIM Or <br /> TESTING LABORATORY <br /> (Page 4 ) <br /> VII SOIL PROFILE AND PERCOLATION TESTS (Continued) <br /> Percolation tests were commenced on May 13, 1991 by a <br /> representative of our firm. Three ( 3 ) percolation tests <br /> conducted at a depth of 42" were disregarded as part of this <br /> report due to failure of water to percolate within the <br /> established requirements set forth by San Joaquin County. <br /> Three ( 3 ) percolation tests performed to the maximum depth <br /> allowed of 25 feet were found to be satisfactory upon completion <br /> of testing. Due to sandy soil conditions and faster percolation <br /> rates, readings were taken 10 minutes apart over a one hour <br /> period. The readings obtained during the last 10 minutes of <br /> testing were used to calculate the percolation rate in minutes <br /> per inch. The results were about one (1 ) minute per inch. See <br /> enclosed test data . <br /> VIII CONCLUSION <br /> Based on the past performance of existing septic systems on the <br /> property and nearby properties, the soil profiles encountered, <br /> and the results of the percolation tests; it is our professional <br /> opinion that the subject property is well suited for the <br /> proposed septic system and for the continued use of the present <br /> septic systems . <br /> Sinc el —� <br /> Y.
