April 1, 2005 <br /> NNOA Project Number: E05034A <br /> Ff �'- G.4 Condition of Borings After Presaturatian <br /> After the 24-hour soak period, the presaturated holes were found to be intact on March 21, 2005. <br /> The percolation test hole contained water on the bottom. <br /> !�l 6.5 . Percolation Test Procedure <br /> .Percolation tests were conducted for the borings on March 21, 2005 in accordance with the <br /> requirements of the-EHD. The pre-test for the one hour test lasted10 minutes; since a satisfactory <br /> percolation rate was observed to continue with the one hour test, the pre-test became the first <br /> reading of the percolation.test.XP ercolation test with a duration of-one hour was performed the <br /> hole. The entirety of the one hour test was observed by Mr. Michael Escotto, Senior Registered <br /> Environmental Health Specialist EHD. <br /> Measurement of the water level during the percolation testwas from a fixed reference point on the <br /> r 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 /> F1bottom level of the percolation test hole. The readings were taken every 10 minutes for a period of <br /> one hour.. <br /> F1x/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 b the EHD as being between 36 and 42 inches in depth;a <br /> p Y g p <br /> satisfactory percolation rate fora shallow testis less than or equal to 60 minutes per inch drop. One <br /> percolation test must demonstrate a satisfactory percolation rate within the proposed septic system <br /> disposal field of each parcel to utilize a standard septic system. Details of the percolation test is <br /> 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): (minute inch) Duration (see notes) <br /> r <br /> P-1 shallow,3/17/05 3.20 16.7 1-hr Satisfactory percolation rate <br /> Note: A satisfactory percolatio tofora" hallo 'test is less th or equal to_60 minutes per inch. <br /> 9 <br />
