February 3,2005 <br /> NOA Project Number: E040143A <br /> Escotto,Registered Environmental Health Inspector,EHD. On February 3,2005, a percolation test <br /> with a duration of one hour was conducted on Parcel 2, the entirety of the test was observed by Mr. <br /> Mike Escotto, 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 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 for the one hour tests were take every 10 <br /> minutes,the readings for the four hour test were taken approximately every 30 minutes. <br /> 6.6 Percolation Test Forms and Results <br /> LThe 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 8. <br /> Table 8. <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 /> P-1 shallow, 1-25-05 3.09 16.67 1-hr Satisfactory percolation rate <br /> (Parcel 1) <br /> P-2 shallow,2-3-05 3.10 16.67 1-hr.

The soils of these <br /> parcels appear to be suitable for a septic system utilizing shallow leach lines or filter beds. <br /> L <br /> 10 <br /> L '-'04 <br /> L <br />
