Table 1 below summarizes the main soil physical and chemical <br />characteristics of the sample depths obtained: <br />TABLE I <br />SOIL PROFILE CHARACTERISTICS AND <br />ANALYTICAL TEST RESULTS <br />SAMPLE DEPTH AND <br />(SAMPLE NUMBER ON <br />TEST RESULT FORM) <br />SOIL <br />CLASSIFICATION <br />SOIL NITRATE- <br />NITROGEN CONTENT <br />pH AND CATION EXCHANGE <br />CAPACITY <br />0"-6" Leachfield Soil <br />(0-6LF) <br />Clay Loam 11 ppm NO,-N 6.5 18.0 meq/100g <br />30"-36" Leachfield <br />Soil <br />(3036L) <br />Clay Loam 8 ppm NO,-N 7.4 16.8 meq/100g <br />0-6" Cropland Soil <br />(0-6CL) <br />Clay Loam 1 ppm NO,-N 6.7 17.6 meq/100g <br />30"-36" Cropland Soil <br />(3036C) <br />Clay Loam 1 ppm NO,-N 7.7 17.9 meq/100g <br />C. PERCOLATION TEST RESULTS <br />SSS§ 6.2. To assess the permeability of the subsurface soils in the proposed leachfield area, the <br />percolation test boring was completed in the location depicted on the Tentative Map found in <br />Appendix C. <br />SSS§ 6.3. After drilling, the sidewall of the perc test boring was scored with a pry-bar to open <br />potentially smeared soil surfaces and the cuttings removed. Two inches of pea gravel was placed <br />at the bottom and a 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 />SSS§ 6.4, 6.5. On June 3, 2019, percolation testing commenced at 0700 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 />A summary of the perc test results with corresponding application rates in gallons of effluent <br />accepted per square foot of soil per day are illustrated below in Table 2: <br />TABLE 2 <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 />Page -3- <br />Chesney Consulting
