Test Hole Percolation Rate Minimum Usable <br /> NO . (Minutes Per Inch) Disposal Area <br /> ( Square Ft . ) <br /> 1 PH1 60 12 , 000 <br /> 2 PH2 60 12 , 000 <br /> The calculated minimum usable disposal areas are not recommended <br /> for design purposes , however , due to the high level of ground <br /> water . <br /> The Soil Profile : Three ( 3) Soil Profile Test Holes were dug to <br /> depths varying from 4 . 9 ft . to 5 . 6 ft for soil profile reporting . <br /> Groundwater was encountered in all of the excavated three ( 3) Soil <br /> Profile Test Holes and on 10-1-98 and 10-15-98 the water levels <br /> measured from 4 . 3 ft . to 5 .0 ft . below the ground surface as shown <br /> on the attached Site Plan "B" . See the attached Site Plans "A and <br /> B" and the "Field Percolation Data Sheet" , as well as the text of <br /> this report , for specific soil layer character and location <br /> details . <br /> Well Water Analysis : See the attached "Far West Laboratories , Inc . <br /> letter , dated October 5 , 1998 , as well as the text of this study <br /> report regarding Nitrate and DBCP well water concentrations . <br /> RECOMMENDATIONS : Due to the closeness of the ground water to the <br /> ground surface (4 . 0 ft . minimum to 5 . 0 ft maximum below the ground <br /> surface) the use of a leach field or seepage pit design is not <br /> acceptable . Instead , in any future development of this property <br /> involving the need for a septic system, a mound septic system <br /> design or a specially engineer designed septic system will be <br /> required . <br />
