L .WO, <br /> LNovember 3, 2004 <br /> NOA Project Number: E040118A <br /> LMeasurement 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 approximately every 30 minutes <br /> for a period of four hours. <br /> L6.6 Percolation Test Forms and Results <br /> 1 The completed percolation test forms are 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 /> l L 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. 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 /> 1S shallow,10-12-04 3.18 1.66 1 h Satisfactory percolation rate <br /> (Parcel 1) <br /> 2S shallow,10-13-04 Water was found in hole <br /> - (Parcel 2) 3.4 4-hr. overnight.No movement, / <br /> failed test.
