' ^ (Zf€e^ " >!€=■ a 5 /aj TO; Filcj PA47" iSpOAtp FROM: Mike Gaffron, Septic System Inspector DATE; May 16, 1978 SUBJECT; Septic Systems - Soil Testing, Stielow Subdivision A review of the soil testing information submitted by Hickock and Associates for the Stielow Subdivision leads me to the following conclusions; I I Lot 1 - Percolation rate 11 min,/inch; 5 min,/inch at secondary site; water table at 2-4 feet; mottled below 3 feet. Water table is too high for a standard system. Slopes of 6-12% on the primary site are too steep for a mound system. Possibilities for this lot are: 1) a mound system in the secondary drainfield area; 2) holding tanks; or 3) declare the lot as unbuildable, 2. I Lot 2 - Percolation rate 24 min,/inch; 23 min,/inch at secondary * site; water table at 3-7 feet. Primary site is near or within existing drainfield. Slopes of 0-6%, Due to high water table, a mound system or shallow trenches would be necessary, i 2-Lot 3 - Percolation rate 83 min,/inch; 83 min,/inch at*secondary site; water table at 3-7 feet; slopes of 6-12%, High water table indicates standard trenches will not be acceptable (soil mottling at 5 ft,, 3 ft,, and 1 ft. indicate a high seasonal water table). Slopes are too steep for a mound system, and perc rates are too slow for shallow trenches. I believe it may be possible to install a mound to the southeast of proposed drainfields where the slope is more level. Additional testing would be necessary. 1/ 4 - Percolation rate 100 min./inch; 33 min./inch at secondary * site. The lot is presently being retested to find a more suitable site. ^ Ubot 5 - Percolation rate 27 min./inch; 53 min./inch at secondary * site. Water table at 8 ft. Soil mottling below 6 ft., slopes 4-12%. A standard system could be installed on this lot. f ^iLot 6 - Percolation rate 67 min,/inch; 30 min./inch at secondary ^ site. Water table at 3.5 - 8 ft. Mottling at 3.5 ft. A mound system would be necessary on this lot due to high water table and slow perc rate. ^ S\T^ /Vo/ZTH S-Z/Xr I’Cir /OoT /\s SiTB bt^r TD S40CO feyecs
