L <br /> November 21, 2006 <br /> NOA Project Number: E06045B <br /> 6.5 Percolation Test Procedure 0'g <br /> Percolation tests were conducted for the borings on October 27,2, accordance with the / <br /> requirements of the EHD. A percolation test with a duration of our h urs were performed for <br /> each hole. The last half an hour of each test was observed by . Ted asiopoulos,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 /> holes were checked for refill. The refill level was approximately 0.5 ft (6 inches) of water above the <br /> Lbottom level of the percolation test hole. The readings were taken every 30 minutes for a period of <br /> four hours. <br /> L6.6 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 betwee36 and 42 inches in depth;a <br /> satisfactory percolation rate for a shallow test is less than or equal 60 minutes per inch drop. A <br /> deep percolation test is defined as being between 3.5 an 25 feet in depth;a satisfactory percolation <br /> L rate for a deep test is 30 min/in or less. One percolation must demonstrate a satisfactory <br /> percolation rate within the proposed septic system disposal field of each parcel to utilize a standard <br /> septic system. Details of the percolation tests are summarized in Table 4.. <br /> L <br /> Table 4. ` <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 /> r <br /> Parcel 1 6.01 No movement 4 hour Failing ercolation Rate <br /> 10-27-06 <br /> Parcel l 3.07 250 4 hour Failing P colation Rate <br /> 10-27-06 <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes p ch. <br /> A satisfactory percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> L <br /> L 8 ".44 <br />
