February,15, 2006 NOA Project Number: E06006A A 1.5-inch diameter PVC pipe with perforations on the bottom was used to measure the drop of water in the percolation test boring. Approximately 2 inches of"pea gravel" were placed in the -bottom of the open soil boring; then the PVC pipe was installed on top of the gravel: "Pea gravel" was backfilled in the annular space. Presaturation of the percolation test-hole occurred on February 1, 2006. The depth of water used to pre-soak was 12 inches above the bottom of the boring. 6.4 Condition of Borings After Presaturation. After the 24-hour soak period, the resaturated hole was found to be intact and on February- p p -. dry 2, 2006. 6.5 Percolation Test Procedure A percolation test was conducted for the boring on February 2, 2006 in accordance with the requirements of the EHD, A percolation test with a duration of four hours was performed. The last half hour of the four hour percolation test was observed by Mr. Michael Escotto,Registered Environmental Health Inspector;EHD. Measurement of the water level during the percolation test was from a fixed reference point on the PVC casing using an electric well sounder with an depth accuracy of 1/l 00th foot. All tabulated values on the field data sheet (appendix) are in decimal feet. After water drop was observed, the holes were checked for refill. The refill level was approximately 0.5 ft (6 inches) of water above the bottom level of the percolation test hole. The readings were taken approximately every half hour for the four hour percolation test. 6.6 Percolation Test Forms and Results The completed percolation test form is included in the appendix of this report. A shallow percolation test is defined by the EHD as being between 36 and 42 inches in depth;a - p - satisfactory percolation rate for a shallow test is less than or equal to 60 minutes per inch drop. One percolation test must demonstrate a satisfactory percolation rate within the proposed septic system disposal field to utilize a standard septic system. Details of the percolation test are summarized in the table below. Summary of Percolation.Test. Test No., Percolation Percolation Rate Test Comment Date Tested Test Dep thfft).
