The following information describes the preparation of the percolation test borings and the actual <br /> Pere <br /> testing: (§ 6.2, 6.3 and 6.5) On June 18, 2005, 0800 his, one shallow perc test boring and one <br /> deeper test boring varying from 7 to 11.2 feet were drilled on proposed Parcels 1, 2, 3 and 4. The <br /> sidewalls of the shallow borings were scored with a pry-bar and the loose material removed. Two <br /> inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted in <br /> the test borings. All test borings were pre-saturated on June 22, 2005 at 0900 hrs with 12 inches of <br /> water. <br /> (§6.4) On June 23, 2005, 0800 hrs, percolation testing commenced for all eight borings. There was <br /> standing water after the 24-hour soak period in two of the shallow perc tests borings, as illustrated in <br /> Table 1 below. Consequently, EHD Pere Test Procedure#1 was conducted for these two borings. <br /> There was no standing water after the 24-hour soak period in the remaining six test borings. <br /> Therefore, Percolation EHD Test Procedure#2 was performed for these borings. The last half <br /> hour of the tests was witnessed by Michael Escotto of the San Joaquin County Environmental <br /> Health Department. <br /> (§ 5.4 and 6.8) The following Table illustrates the proposed Parcel number,potential septic <br /> t system structure based on depth of passing perc rates, proposed acreage, post soak period status <br /> and perc test results for the respective perc test depths: <br /> TABLE 1 <br /> MERCOLATIONITESTIRESUI.'S <br /> PROPOSED PARCEL PROPOSED PERC TEST DEPTHS: POST SOAK PERC TEST <br /> AND POTENTIAL ACREAGE SHALLOW PERIOD RESULTS <br /> SEPTIC SYSTEM DEEP STATUS <br /> STRUCTURE <br /> Parcel 1 2.2 Acres 42 INCHES --4 Inches FAILED <br /> Existing Leachlines Standing Water (125 min/in) <br /> ' and Seepage Pits No standing 4.1 min/in <br /> (Has Existing Well) 120 INCHES (10 FEET) <br /> Water in Hole <br /> Parcel 2 2.6 Acres 42 INCHES —1 Inches 50.0 min/in <br /> Leachlines and standing Water <br /> Sumps 84 INCHES(7 FEET) No Standing 4.2 min/in <br /> Water in Hole <br /> Parcel 3 2.5 Acres 42 INCHES No standing 35.7 min/in <br /> Leachlines and water in Hole <br /> Seepage Pits 114 INCHES(9.5 FEET) No Standing FAILED <br /> Water in[-tole (41.7 min/in) <br /> Parcel 4 2.4 Acres 36 INCHES No Standing 3.9 min/in <br /> Leachlines and Water in Hole <br /> Seepage Pits 134 INCHES(11.2 FEET) No Standing FAILED <br /> Water in Hole (41.7 min/in) <br /> Page -3- <br /> Chesney Consulting <br />
