The soil nitrate -nitrogen concentration is 20 ppm which is similar to what was observed _n the <br />original Study. From the data obtained from these original Studies and the data from the soil test <br />results for this Study, substantiate a 31 % denitrification potential which will be used in the <br />loading calculations below. <br />NLS§ 3.3, SSS§ 5.3, 5.4. Table 1 below summarizes the analyzed soil physical and chemical <br />characteristics from the retrieved soil sample: <br />TABLE 1 <br />SOIL PROFILE CHARACTERISTICS AND <br />ANALYTICAL TEST RESULTS <br />SOIL F 'XTURE <br />pH AND <br />NITRATE- <br />SODIUM <br />MAGNESIUM <br />NITRA'ITE:- <br />CLASSIFICATION <br />CATION <br />NITROGEN <br />CATION <br />CATION <br />NITROGEN <br />M <br />EXCHANGE: <br />PERCENTAGE <br />PERCENTAGE <br />SAND/SILT/CLAN' <br />CAPACITY <br />PERCENTAGES <br />36"_40" <br />Sandy Loam <br />5.7 <br />1 <br />20 ppm NO, -N <br />3.2% <br />18.8°/1, <br />20 ppm <br />74% 17% 9% <br />5.3 meq/1008 <br />C. PERCOLATION TEST RESULTS <br />SSS§ 6.2. To assess the permeability of the proposed effluent disposal area, a percolation test <br />boring was hand -drilled to a depth of 40 inches, as referenced above. Test location is depicted on <br />the Google Earth Aerial photo in Appendix C. <br />SSS§ 6.3. After drilling, the sidewall of the boring was scored with a pry -bar to open potentially <br />smeared soil surfaces and the cuttings removed. Two inches of pea gravel was placed at the <br />bottom and a three-inch perforated PVC pipe was inserted in the boring to prevent cave -iris. 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 />SSS§ 6.4, 6.5. On April 21, 2022, percolation testing commenced. No standing water was <br />measured after the 24 -hr soak period. Consequently, EHD Perc Test Procedure #2 was conducted. <br />Testing was done over a four-hour period to induce maximum soil saturation. A summary of the <br />perc test results with corresponding application rates in gallons of effluent accepted per square foot of <br />soil per day are illustrated in Table 2 and discussed in the Conclusions Section: <br />TABLE 2 <br />PERCOLATION TEST RESULTS WITH CORRESPONDING <br />APPLICATION RATES IN GALLONS / FT / DAY <br />40" PERC TEST 1 250 min/inch / 0.100 gallons/ft2/dlay <br />Application Rates adapted from Waste Quality Control for Siting, Design, Operation and Maintenance of On-site Wastewater Treatment Systems, based on the Perc Rate. <br />Chesney Consulting <br />
