PERCOLATION AND INFILTRATION TEST RESULTS SSS§ 6.2. To assess the permeability and the infiltration capabilities of the proposed mound system area,two percolation tests were completed in this area as depicted in the Site Plan. As referenced, the test depths were 24 and 36 inches below existing grade, giving a comparatively detailed observation of subsurface permeability at these two strata. Only the 36-inch test depth is recognized as "official'by EHD. The 24-inch test depth represents infiltration properties of the soil near the surface._ SSS§ 6.3. On August 8, 2016,the two perc test borings were drilled. The sidewalls of each boring were scored with a pry-bar to open potentially smeared sidewalls. Two inches of pea gravel was placed at the bottom and three-inch perforated PVC pipe was inserted in each test boring. Each boring was then pre-saturated with water at 3x each bore hole volume at 0900 hrs; 24 hrs before the start of testing. This greatly exceeds EHD pre-saturation standards. SSS§ 6.4,16.5. On August 9, 2016, percolation testing commenced. No standing water was observed after the 24-hr soak period in either of the two test borings. Consequently, EHD Perc Test Procedure#2 was conducted in which testing was done over a four-hour period to induce maximum soil saturation. The test results indicate comparatively rapid perc rates considering the soil type at 10.0 minutes per inch(min/in) and 17.8 min/in as noted below. A summary of the perc test results with corresponding application rates in gallons of effluent accepted per square foot of soil per day are found in Table 2: TABLE 2 PERCOLATION TEST RESULTS FOR THE DISPOSAL AREA MOUND SYSTEM WITH CORRESPONDING APPLICATION RATES IN GALLONS J FTS/DAY 24 INCH DEEP PERC TEST BORING 10.0 min/inch / 0.800 gallons/ft'/day PERCOLATION RATE/APPLICATION RATE , 36 INCH DEEP PERC TEST BORING 17.8 min/inch / 0.686 gallons/ft2/day PERCOLATION RATE/APPLICATION RATE ' Application Rates adapted from Water Quality Control Policy for Siting,Design,Operation,and Maintenance of Onsite Wastewater Treatment Systems. 4 Chesney Consulting
