PERCOLATION TEST RESULTS <br /> SSS§6.2. To assess the permeability at prescribed depths of the on-site soils,the two <br /> aforementioned percolation test borings were completed in the locations depicted on the <br /> preliminary Site Plan found in Appendix C. <br /> SSS§ 6.3. After drilling the perc test borings, the sidewalls of the shallow boring was scored <br /> with a pry-bar to open potentially smeared sidewalls. The deep test boring could not be scored <br /> due to its depth. Two inches of fine gravel was placed at the bottom and three-inch perforated <br /> PVC pipe was inserted in each test boring. On June 25,2012, each boring was pre-saturated with <br /> 24 inches of water at 0900 hrs, 24 hrs before the start of testing. <br /> SSS§ 6.4, 6.5. On June 26,2012,percolation testing commenced. No standing water was <br /> observed after the 24-hr soak period in both of the test borings, consequently, EHD Perc Test <br /> Procedure#2 was conducted for both test borings. Testing was done over a four-hour period to <br /> induce maximum soil saturation. <br /> The test results indicat rapid ut not excessively rap'dtperc rates at the 42 inch and 96 inch depth <br /> test depths.
