The shallow percolation test results reveal that very little effluent percolation will occur <br /> from the leachline trenches. Acceptable percolation was observed in the deep test boring at 19.2 ft, <br /> representative of seepage pits. The soil stratum at this depth will be conducive for effluent <br /> management with a perc rate of 14.7 min/in. Therefore, seepage pits will manage most of the <br /> effluent from a future house on this Parcel. Although the perc test was run at the highest i. 6 <br /> encountered depth of permeable material, 25 feet deep seepage pits should be installed. <br /> This report is in conjunction to my original Soil Suitability Study for this project, dated August 10, <br /> 2004, which is found in Appendix D.
