I <br />, F <br /> March 16, 2006 <br /> NOA Project Number: E0601 1A <br /> Measurement of the water level during the percolation test was from a fixed reference point on the <br /> PVC casing using an electric well sounder with an depth accuracy of 1/100th foot. All tabulated <br /> values on the field data sheet (appendix) are in decimal feet. After water drop was observed, the <br /> F1 holes were checked for refill. The refill level was approximately <br /> 0.5 ft 6 inches <br /> ( ) of water above the <br /> bottom level of the percolation test hole. The readings were taken approximately every 30 minutes <br /> for a period of four hours. <br /> P6.6 Percolation Test Forms and Results <br /> i F1 The completed percolation test form is included in the appendix of this report. i <br /> A shallow percolation test is defined by the EHD as being between 36 and 42 inches in depth; a <br /> satisfactory percolation rate for a shallow test is less than or equal to 60 minutes per inch drop. <br /> Details of the percolation test is summarized in the following table. <br /> F, Table 5 <br /> Summary of Percolation Tests. <br /> Test No., Percolation Percolation Rate Test Comment <br /> ri Date Tested Test Depth(ft) (minutes/inch) Duration <br /> P-1 shallow <br /> 2-7-06 3.79 2 97 4-hr (satisfactory p colation rate <br /> Note: A satisfactory percolation rate fora"shallo est is less than or equ u -per-"c . <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of the proposed parcels have demonstrated a satisfactory <br /> percolation rate in accordance with the requirements of the EHD. The soils of the Site appear to be <br /> suitable for a standard septic system. However, due to ground water being encountered at 8.7 feet <br /> below ground surface, a semi-raised filter bed septic system may be required by EHD for any future <br /> development. EHD requires a minimum of five feet separation between the bottom of the disposal <br /> field and ground water. <br /> 6.8 Discussion of Septic System Sizing <br /> See recommendation/mitigation measures in Part II, Nitrate Loading Study included in this report. <br /> 7.0 CONCLUSIONS f , <br /> In summary, a atisfactop. rcolation rate of the soil was achieved on the proposed parcel.
