rNLS§3.3, SSS§ 5.3, 5.4. Table 1 below summarizes the soil physical and chemical characteristics <br /> at the proposed soil-effluent interface: <br /> 1 TABLE 1 <br /> y SOIL PROFILE CHARACTERISTICS AND <br /> ANALYTICAL TEST RESULTS <br /> SAMPLE DEPTH AND SOIL SOIL NITRATE- pH AND <br /> r (SAMPLE NUMBER ON CLASSIFICATION NITROGEN CONTENT CATION EXCHANGE CAPACITY <br /> TEST RESULT FORM) I In meq/100g <br /> 3 FT DEPTH Clay Loam 73 ppm NO -N 7.9 20.9 me /100 <br /> C. PERCOLATION TEST RESULTS <br /> SSS§6.2. To assess the permeability at the test depth which corresponds with the soil-effluent <br /> interface,the aforementioned percolation test boring was completed in the locations depicted on the <br /> Site Plan found in Appendix D. <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 fine gravel was <br /> 1 placed at the bottom and three-inch perforated PVC pipe was inserted in the test boring. After these <br /> procedures,the boring was pre-saturated with 12 inches of water approximately 24 hrs prior to the <br /> start of testing. <br /> i <br /> SSS§6.4,6.5. On June 14, 2016,percolation testing commenced at 0600 hrs. No standing water <br /> j was observed after the 24-hr soak period. Consequently, EHD Perc Test Procedure#2 was <br /> t conducted. Testing was done over a four-hour period to induce maximum soil saturation. <br /> The test results indicate a perc rate of 62.5 min/in after complete soil saturation. A perc rate of 60 <br /> min/inch or faster is considered acceptable. The water level was not refilled to the starting level for <br /> the last 30 minute test,which slowed percolation due to lower head. This illustrates the effect that <br /> head pressure has on soil permeability. 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 in Table <br /> 2: <br /> TABLE 2 <br /> j 1 PERCOLATION TEST RESULTS WITH CORRESPONDING <br /> APPLICATION RATES IN GALLONS/FT'/DAY <br /> 36 INCH DEEP PERC TEST BORING 62.5 min/inch / 0.190 gallons/ft2/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> a OFFICIAL PERC TEST <br /> j Application Rates adapted from Waste Quality Control for Siting,Design,Operation and Maintenance of On-sire Wastewater Treatment Systems and is based on the Perc Rate. <br /> t <br /> j Page -3- <br /> Chesney Consulting <br /> Y <br />
