PERCOLATION TEST RESULTS <br />SSS§ 6.2. As referenced, to assess the permeability of the proposed effluent disposal area soils, <br />percolation test borings were completed as noted above. Three perc tests were conducted within the <br />disposal area to adequately assess the underlying soil characteristics. <br />SSS§ 6.3. After drilling, the sidewall of the shallow 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 at <br />the bottom of each test boring, and a three-inch perforated PVC pipe was inserted in each boring to <br />mitigate cave-ins. After these procedures, the borings were pre -saturated with 12 inches of water <br />approximately 24 hrs prior to the start of testing. <br />SSS§ 6.4, 6.5. On July 30, 2021, percolation testing commenced at 0700 hrs. No standing water <br />was observed in any of the three test borings after the 24 -hr presaturation period. Consequently, <br />EHD Perc Test Procedure #2 was conducted. Testing was done over a four-hour period to induce <br />maximum soil saturation. A summary of the perc test results with corresponding application rates in <br />gallons of effluent accepted per square foot of soil per day, are illustrated below: <br />TABLE 2 <br />PERCOLATION TEST RESULTS WITH CORRESPONDING <br />APPLICATION RATES IN GALLONS / FT'/ DAY <br />83.3 min/inch / 0.123 gallons/ft`/day <br />3 Ft Perc Test <br />25.0 min/inch / 0.589 gallons/ft=/day <br />12 Ft Perc Test <br />41.7 min/inch / 0.400 gallons/ftZ/day <br />23 Ft Perc Test <br />Average Application Rate =0.371 gallons/W/day <br />Application Rates adapted from: Water Quality Control for Siting, Design, Operation and Maintenance of On-site Wastewater Treatment Systems <br />Page -3- <br />Chesney Consulting <br />
