L <br /> LJune 1, 2006 <br /> NOA Project Number: E05148B <br /> Leach hole. The last half an hour of each test was observed by Mr. Ted Tasiopoulos,Registered <br /> Environmental Health Specialist, EHD. <br /> L 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 /> L bottom 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 /> L The completed percolation test form is included in the appendix of this report. <br /> r- <br /> A shallow percolation test is defined by the EHD as being betweeh�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 testis defined as being between 3.5 and 25 feet in depth; a satisfactory percolation <br /> rate for a deep test is 30 min/in or less. One percolation test must demonstrate a satisfactory <br /> L 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 Table 4. <br /> Summa of Percolation Tests <br /> Test No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minutes/inch) Duration (see notes) <br /> ti.
