February 2,2006 <br /> NOA Project Number: E05058B <br /> EHD. A percolation test with a duration of four hours was performed for each hole on Parcels 1, 2, <br /> 3 and 4.The final half-hour of each four-hour percolation test was observed by Mr. David Van <br /> Dyne and Mr. Ted Tasiopoulos,both Registered Environmental Health Inspectors,EHD. A <br /> percolation test with a duration of one hour was performed for each hole on Parcels 5, 6, 7 and 8 in <br /> accordance with the requirements of the EHD. The entirety of each one hour test was observed by <br /> Mr. David Van Dyne,Registered Environmental Health Inspector, 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-g--q with an depth accuracy of 1/100th foot. All tabulated <br /> values on the field data shee (appendix) #e in decimal feet. After water drop was observed, the <br /> holes were checked for refill. The refillrlevel was approximately 0.5 ft (6 inches) of water above the <br /> bottom level of the percolation tes -ole. The readings were taken approximately every 30 minutes <br /> for a period of four hours for the four hour test and readings were taken every ten minutes for the <br /> one hour test. <br /> 6.6 Percolation Test Forms and Results <br /> 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 /> satisfactory percolation rate for a shallow test is less than or equal to 60 minutes per inch drop. <br /> Details of the percolation tests are summarized in Table 4. <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 /> Parcel 1 3.07 5.81 4 hour Satisfactory Percolation Rate <br /> Parcel 2 3.19 7.14 4 hour Satisfactory Percolation Rate <br /> Parcel 3 3.12 4.8 4 hour Satisfactory Percolation Rate <br /> Parcel 4 3.06 15.63 4 hour Satisfactory Percolation Rate <br /> Parcel 5 3.0 1.85 1 hour Satisfactory Percolation Rate <br /> Parcel 6 3.12 2.14 1 hour Satisfactory Percolation Rate <br /> Parcel 7 3.03 1.24 1 hour Satisfactory Percolation Rate <br /> Parcel 8 3.11 2.69 1 hour i Satisfacto Percolation Rate <br /> Note: A satisfactory percolation rate for a"shallow'test is less than or equal to 60 minutes per inch. <br /> 8 "44 <br />
