PERCOLATION TEST RESULTS LINER CHARACTERISTICS SSS§ 6.2. To assess the permeability of the soils in the tested eDeertion tests were completed in the area depicted on the EHD Aerial Photo found in hese test depths represent the approximate depth elevation of a future soil-effluent oor of the leachline trenches, sumps and seepage pits). SSS§ 6.3. On October 9, 2007, the perc test borings were drilled in the referenced location with a Mobile Drill rig and solid-.stem auger and then covered. The sidewalls of the shallow boring was scored with a pry-bar since the soil contained higher percentages of silt and clay. Scoring the sidewalls is a critical procedure and"opens"potentially smeared surfaces. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted in each test boring. The borings were pre-saturated with 12 inches of water at 0900 hrs on October 25, 2007, 24 hrs before the start of testing. SSS§ 6.4, 6.5. On October 26, 2007, percolation testing commenced./o standing water was observed after the 24-hr soak period in any of the threet�ongs. Consequently, EHD Pere Test Procedure#2 was conducted in which testing was done over a four-hour period to induce maximum soil saturation. The EHD allows a maximum rate f 60 mini for a shallow perc rate and 30 min/in' for deeper perc tests. A percolation rate (actually t e inver of a rate) "faster" than 5 min/in requires modification to the disposal effluent interface soils. These changes are also pursuant to EHD regulations and EPA regulations found in the EPA Design Manual- Onsite Wastewater Treatment and Disposal Systems. Although the deeper tests approached this rate, they were not exceeded. A summary of the perc test result with corresponding application rate in gallons of effluent accepted per square foot of soil, per day are found in Table 2: 4 Chesney Consulting
