Soil Suitability Study MIS-98-37 Parcel Nos . 1 , 2 , 3 , 4 , & 5 <br /> percolation test holes are shown on the attached "Site Plans" . The <br /> failure of these five shallow preliminary percolation tests <br /> determined the need for deep percolation testing. <br /> Three (3 ) deep percolation test holes were drilled on December 5 , <br /> 1997 and four (4 ) more were drilled on December 29 , 1998 . No <br /> further testing on two of these deep percolation test holes was <br /> determined to be needed after drilling by visual observation of the <br /> soil character . Only Deep Percolation Test Hole Nos . DP1A, DP2A, <br /> DP3B, DP4B and DP5A noted in the "Soil Profile And Percolation Test <br /> Hole Drilling" topic earlier in this soil suitability study report <br /> were formaly tested. <br /> Five ( 5) deep percolation tests were conducted and performed <br /> on Deep Percolation Test Hole Nos . DP1A, DP2A, DP3B, DP4B and DP5a <br /> in accordance with the percolation test procedures outlined in the <br /> "Manual Of Septic Tank Practice" , published by the Department Of <br /> Health, Education And Welfare and the requirements of the San <br /> Joaquin County Public Health Service , Environmental Health <br /> Division . <br /> The results of the deep percolation tests performed on the <br /> above mentioned five ( 5) test holes is summarized and tabulated as <br /> follows : <br /> TEST RESULTS : <br /> Parcel Test Bole Per Rate minimum Usable En�iner <br /> N0 .

One on Parcel No . 4 , 16750 <br /> Clements Road, and one on Parcel No . 3 , 16751 Clements Road, at the <br /> locations shown on the attached "Tentative Parcel map" and the <br /> "Site Plans" . Two samples were taken from each well . One sample was <br /> taken for testing for Nitrate (NO3 ) and the other sample was taken <br /> for testing for Dibromochloropropane (DBCP) . The results of the <br /> tests on the sampled water from the wells for Dibromochloropropane <br /> (DBCP) and Nitrate (NO3 ) are tabulated as follows : <br /> R.E.
