[7] CONCLUSIONS <br /> The results of the percolation tests indicate that there is fast <br /> percolation at the 8. 5 foot depth (1. 6 min/in) and no percolation <br /> at the 42 inch depth since there was standing water in the test <br /> hole after 24 hrs. <br /> Although the percolation rate of 1. 6 min/in translates to a <br /> recommended sewage disposal area of 6, 000 square feet for the deep <br /> test boring, it is our recommendation that there be a 12 , 000 square <br /> foot leaching area with seepage pits due to the proximity of the <br /> Lone Tree Creek. This recommendation is primarily a protection <br /> measure of the underlying groundwater, and of Lone Tree Creek. <br /> The seepage pit and leach lines easily comply with the required <br /> separation distances of 150 feet from a flowing body of water. It <br /> is estimated that there will be an approximately 275 foot distance <br /> between the seepage pit and Lone Tree Creek. <br /> As noted above, the water table is approximately 80 feet below the <br /> soil surface. Therefore, the groundwater level in this area is <br /> unquestionably below the ten foot minimum distance between the <br /> bottom of the seepage pits (approximately 25 feet) and the highest <br /> anticipated depth to groundwater at this point in time. <br /> Based upon 1) the above documented information from the percolation <br /> testing pertaining to the recommended disposal structures and <br /> areas, along with the placement of the proposed seepage pit and <br /> leach lines within a percable soil profile, 2) the highest <br /> anticipated depth to groundwater, 3) the distance protection <br /> measure of the proposed septic system from the Lone tree Creek, <br /> there should not be any adverse impact to the quality of the local <br /> area surface water or groundwater from this proposed septic system. <br /> 5 <br /> S,t : 4alit� ontrol Inspection <br />
