FFThelastur of the four-hour tests was witnessed by Mike Escotto, R.E.H.S. of the San Environmental Health Deparhnent. Table summarizes the proposed Parcel number, septic system structure to be on depth of acceptable perc rates, Street Address, A.P.N. Number, post soak period status and percolation test results at the perc test depth: PERCOLATION TEST RESULTS AND RELATED DATA LOT NUMBER AND ADDRESS PERC TEST DEPTHS: POST-SOAK PERC TEST SEPTIC SYSTEM SHALLOW PERIOD RESULTS STRUCTURE TOBE INSTALLEDDA.P.N.NUMBER DEEP STATUS Lot 40 28655 East Via 42 INCHES _Io Inches FAILED Leachlines and Casilina Street Standing water (0 min/in) Seepage Pits (Domestic Well is 187-40044 264 INCHES(22 FEET) No Standing 16.7 min/in scheduled to be water in Hole constructed.) CONCLUSIONS Acceptable percolation was achieved in an area within 100 feet of the future effluent leachfield for the Daluz's home at the deeper test depths representative of seepage pits. The shallow percolation test results reveal that very little, if any effluent percolation will occur from the leachline trenches. Although the percolation test boring was terminated at 22 feet where the highest elevation permeable soil was encountered, seepage pits should be installed to the typical maximum depth of 25 feet. The well log for the domestic well being drilled across the street from the Daluz's house illustrates a soil morphology of intervening sand and clay strata. A significant clay stratum exists from 64 feet to 130 feet. This stratum should be beneficial in attenuating the downward migration of nitrate that may form from septic effluent.
