At this pH, ammonium will have a propensity to remain in the ammonium form and not as ammonia. <br /> The CEC measures the ability of the soil to theoretically trap and hold ammonium molecules. The / <br /> CEC at 15.7 meq/100g illustrates a medium-high potential for the clay soil to retain ammonium <br /> molecules within thesoilenvironment. <br /> NLS§ 3.3 SSS§ 5.3,5.4/ Table 1 below summarizes the soil physical and chemical <br /> characteristics at the proposed soil-effluent interface: <br /> TABLE 1 <br /> SOIL PROFILE CHARACTERISTICS AND <br /> ANALYTICAL TEST RESULTS <br /> SAMPLEDF.PTII AND SOIL SOIL NTT'R.A'rE- PH AND <br /> (SAMPLE NUMBER ON CLASSIFICATION NITROGEN CONTENT CATION EXCHANGE CAPACITY <br /> TEST RESULT FORM).. .

To assess the permeability at the test depth which corresponds with the soil-effluent <br /> interface, the percolation test boring was completed in the location depicted on the Septic System <br /> design plans found in Appendix B. <br /> SSS§ 6.3. After drilling, the sidewall of the boring was scored with a pry-bar to open potentially <br /> smeared soil surfaces that may have occurred due to the clay soil. Two inches of pea gravel was <br /> placed at the bottom and a three-inch perforated PVC pipe was inserted in the test boring. After <br /> these procedures,the boring was pre-saturated with 12 inches of water approximately 24 hrs prior <br /> to the start of testing. <br /> l <br /> SSS§ 6.4, 6.5. On May 4, 2017, percolation testing commenced at 0600 hrs. No standing water <br /> was observed after the 24-hr soak period. Consequently, EHD Perc Test Procedure #2 was <br /> conducted. Testing was done over a four-hour period to induce maximum soil saturation. <br /> The test results indicate a perc rate of 11.5 mi'n/in after complete soil saturation. A perc rate of 60 <br /> min/inch or faster is considered acceptable. A summary of the perc test results with corresponding <br /> application rates in gallons of effluent accepted per square foot of soil per day are illustrated below: <br /> TABLE2 <br /> PERCOLATION TEST RESULTS WITH CORRESPONDING <br /> APPLICATION RATES IN GALLONS/FTS/DAY <br /> 36 INCH DEEP PERC TEST BORING 11.5 min/inch / 0.771 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> OFFICIAL PERC TEST <br /> Application Rates adapted from Waste Quality ConlroiforSMw Design,Operetim andM.., ,.of On-site Wastewater Treatment Systems,based on the Pero Rate. <br /> Page -3- <br />
