The reference point used to determine the final percolation <br /> rate for both the percolation tests on the two (2) parcels consisted of the upper edge of a <br /> small portion of a lath. <br /> 9.0 Test Results. <br /> Parcel !I Test Hole Shallow Test Tyne Of Septic System Minimum Usable <br /> No. No. Percolation Rate Disposal Area <br /> (Minutes/Inch) (Square Feet) <br /> j 1 PI 120 Mounded 12,000 <br /> i 2 P2 240 Mounded 12,000 <br /> I <br /> 10.0 Recommendations: The site restrictions on both Parcels 1 and 2 of the determined <br /> soil percolation rates not achieving a minimum water level drop of 1/z" drop in thirty(30) <br /> minutes (Percolation Rate=60 minutes per inch) and also the high ground water level. <br /> require that a mounded septic system elevated above the natural ground surface to be <br /> used.
