_ August 31, 2004 <br /> NOA Project Number: E04060A <br /> Table 6. <br /> Summary of Percolation Tests. <br /> Test No., Parcel Percolation Percolation Test Comment <br /> Date Tested Test Depth Rate Duration (see notes) <br /> (ft) (minutes/inch) <br /> P-1 shallow, 8/5/04 24 3.26 6.4 4 hrs. Satisfactory percolation rate. <br /> P-2 shallow, 8/6/04 25 3.12 2.8 1 hr. Satisfactory percolation rate. <br /> P-3 shallow, 8/12/04 23 3.22 2.7 1 hr. Satisfactory percolation rate. <br /> P-4 shallow, 8/5/04 22 3.49 62.5 4 hr. Failed. <br /> _ P-5 shallow, 8/12/04 22 3.38 15 4 hr. Satisfactory percolation rate. <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes per inch. <br /> 6.5 Discussion of Percolation Test <br /> The soils within the areas tested have demonstrated satisfactory percolation rates in <br /> accordance with the requirements of the EHD. The soils of the Site appear to be suitable for a <br /> septic system utilizing shallow leach lines. Based on the ground water maps consulted, it does <br /> not seem likely that sumps will be appropriate. <br /> 6.6 Required Size of Septic System <br /> The EHD Sewage Standards should be followed to size the septic system. <br /> 7.0 PRELIMINARY NITRATE LOADING ANALYSIS <br /> Because of concerns about nitrate leaching into ground water from septic systems, a nitrate <br /> loading analysis was required by the EHD for the proposed facility to measure the potential <br /> concentration of percolating effluent and rain fall over the long term. Where percolating <br /> effluent leaches into the ground, ground water quality may be impacted to some degree should <br /> the effluent reach ground water. <br /> The nitrate loading analysis is considered preliminary due to the fact that no specific project <br /> has been proposed to date. Two scenarios were considered above to explore some potential <br /> uses of the property. <br /> 12 <br />
