F) <br /> PApril 1,2005 <br /> NOA Project Number: E05034A <br /> FI -/ 6.4 Condition of Borings After Presaturat ion <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 /> k <br /> kl�3 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. Tl e pre-test for the one hourtest lasted 10 minutes,since a satisfactory <br /> F1percolation rate was observed to continue with the one hour test, the pre-test became the first <br /> reading of the percolation test. A percolation 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 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 /> r holes were checked for refill..The refill level was approximately 0.5 ft (6.'inches) of water above the <br /> I bottom level of the percolation test hole. The readings were taken every 10 minutes for a period of <br /> ! one hour. <br /> pf`6.6 Percolation Tesi-Forrns 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 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 /> F1 Table 5. <br /> Summary of Percolation Tests.:. <br /> F1Test No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minuted inch) Duration- < _ (see notes) <br /> f <br /> P-1 shallow,3/17/05 3.20 16.7 1-hr Satisfacto percolation rate <br /> Note: A satisfactory.percolatio tofora" hallo 'testis less th or equal to 60 minutes per inch. <br /> F - <br /> 9 <br />
