October 11,2005 <br /> NOA Project Number: E05111B <br /> EHD. Some of the tests were observed by Mr. Michael Escotto, Registered Environmental Health <br /> Inspector,EHD and the rest were observed by Lisa Medina,Senior Registered Environmental <br /> Health Inspector,EHD. Please see percolation forms in the appendix of this report for specific <br /> details. <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 /> holes were checked for refill. The refill level was approximately 0.5 ft (6 inches) of water above the <br /> bottom level of the percolation test hole. The readings were taken every 30 minutes for a period of <br /> four hours. <br /> 6.6 Percolation Test Forms and Results <br /> The completed percolation test form is included in the appendix of this report. <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. A <br /> deep percolation test is defined as being between 3.5 and 25 feet in depth;a satisfactory percolation <br /> rate for a deep test is less than or equal to 30 minutes per inch drop. One percolation test must <br /> demonstrate a satisfactory percolation rate within the proposed septic system disposal field of each <br /> parcel to utilize a standard septic system. Details of the percolation tests are summarized in Table 5. <br /> Table 5. <br /> Summary of Percolation Tests. <br /> Test No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minutes/inch) Duration (see notes) <br /> P-1 Shallow 3.28 17.86 4 hours Satisfactory Perc Rate <br /> P-2 Shallow 3.14 7.14 4 hours Satisfactory Perc Rate <br /> P-3 Shallow 3.17 8.93 4 hours Satisfactory Perc Rate <br /> P-4 Shallow 3.22 83.3 4 hours Failing Perc Rate <br /> P-4 Deep 24.70 3.84 4 hours Satisfactory Perc Rate <br /> P-5 Shallow 3.17 19.23 4 hours Satisfactory Perc Rate <br /> P-6 Shallow 3.03 4.10 4 hours Satisfactory Perc Rate <br /> P-7 Shallow 3.13 4.55 4 hours Satisfactory Perc Rate <br /> P-8 Shallow 3.05 no movement 4 hours Failing Perc Rate <br /> P-8 Deep 24.52 4.63 4 hours Satisfactory Perc Rate <br /> 9 "004 <br />
