PERCOLATION TEST RESULTS SSS§ 6.2. To assess the permeability at prescribed depths hof°the on-site soils, the aforementioned three percolation test borings were completed in the locations depicted on the Site Plan found in Appendix C. The deep test boring was terminated at 22 ft below grade because a more permeable soil was observed at this depth in the 25 ft exploratory boring than what was observed at the 25 ft depth. SSS§ 6.3. After drilling the perc test borings, the sidewalls of the shallow boring were scored with a pry-bar to open potentially smeared sidewalk. The deeper borings could not be scored due to their depths. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was I' inserted in each test boring. On June 2, 2008, each boring was pre-saturated with 12 inches of water at 0900 hrs, -24 hrs before the start of'testing. SSS§ 6.4, 6.5. On.June 3, 2008, percolation testing commenced, .Approximately four inches of standing water was observed after the 24-hr soak period in the 42-inch deep hole. -Consequently, EHD Perc Test Procedure#1 was conducted for this test baring. No standing-water was observed in the other two test borings, therefore EHD Perc Test Procedure ##2 was conducted. Testing was done over a four-hour period to induce maximum.soil saturation. Only the 42-inch test boring and the l` 264 inch deep boring are recognized as"official"by EHD. The 128 inch deep boring is unofficial v� and was conducted to measure the permeability of the encountered soil characteristics at this depth. The test results indicate a virtually nonexistent perc rate at the 42-inch depth test_depth after complete soil saturation, and favorable perc rates at the deeper depths. A summary of the perc test results with corresponding application ratesin gallons of effluent accepted per square foot of soil per day are illustrated in Table 2: i 4 Chesney Consulting
