PERCOLATION TEST RESULTS <br />SSS§ 6.2. To assess the permeability of the existing disposal area soils, three percolation test <br />borings were completed as illustrated on the aerial photo in Appendix C. The shallow boring at the <br />36 inch depth is representative of the permeability occurring at leachline depths. The 8 ft boring <br />depth represents permeability at the sump structure depth. The 20 ft exploratory boring was <br />converted to a percolation test boring after soil sampling procedures were completed to measure <br />percolation at the deeper depths. <br />SSS§ 6.3. After drilling, the sidewalls 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 all three borings and a three-inch perforated PVC pipe was inserted in each test boring <br />to prevent 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 December 30, 2021, percolation testing commenced. No standing water was <br />observed in the 36 inch and 8 ft borings after the 24-hr soak period. Approximately 3 inches of <br />standing water was measured in the 20 ft boring after the 24-hr soak period. Consequently, EHD <br />Perc Test Procedure #2 was conducted for the shallow borings and Procedure #1 for the 20 ft boring. <br />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: <br />Page -3- <br />Chesney Consulting
