�. Soil Suitability Study**MS-01-01** APN: 255-100-07**3Parcels,Each 43.67 Acres**139.11 Acres Total PERCOLATION TEST: Three percolation test holes were determined to be needed to create three(3) parcels out of a larger single parcel as a result of inquiries made to the San Joaquin County Public Health Service,Environmental Health Division. On Wednesday, August 8, 2001, I dug one (1) shallow 8" diameter percolation test hole thirty-seven inches deep on Parcel 3. On the same day the property owner excavated a Soil Profile Test hole on Parcel 3 and two (2)percolation test holes with a backhoe. One percolation test hole was on Parcel 1 and the other percolation test hole was on Parcel 2. The Soil Profile Test hole on Parcel 3 was excavated to a maximum depth of twelve feet and four inches(12'04")and the percolation test holes on Parcels 1 and 2 were dug to a depth of twenty(20)inches and then I hand augured each of the percolation test holes on Parcels 1 and 2 to an additional sixteen inches (16")for a total depth of thirty-six(36") on each of the two (2) holes. Also on Wednesday, August 8, 2001,the percolation test holes on Parcels 1 and 3 were presoaked overnight and percolation readings were conducted on August 9, 2001. The percolation Test hole on Parcel 2 was presoaked on August 9, 2001 and percolation readings were conducted on August 10, 2001. The percolation test holes are identified as 1, 2 and 3 on the attached"Percolation Data Sheets"and the"Tentative Parcel Map". The percolation tests conducted were performed in accordance with the percolation test procedures outlined in the "Manual Of Septic Tank Practice" published y by the Department Of Health Education And Welfare and the requirements of the San Joaquin County Public Heath Service,Environmental Health Division. Percolation Test Holes 1, 2 and 3 shown on the attached"Parcel Map"were tested over a four-hour period and the results of the four-hour percolation tests are tabulated below: TEST RESULTS: Parcel No. Test Hole No. Percolation Rate Minimum Usable Area (Minutes Per Inch) (Square Feet) 1 1 30 10,000 2 2 20 8,000 } 3 3 30 10,000 RECOMMENDATIONS: 10,000 square feet minimum usable disposal areas are recommended for both Parcels 1 and 3 and a 8,000 square feet minimum usable disposal area is recommended for Parcel 2 to accommodate subsurface horizontal leach fields. WELL WATER ANALYSIS: Well water was tested for Dibromochloropropane (DBCP),Nitrates (NO3)as well as some other chemical concentrations. The results of this testing is contained in the Michael M.
