The original design <br /> completed by SP Testing, Inc. shows 1 system with 18" of rock below <br /> the distribution pipe, only 6" & 12" of rock was found. The original soil <br /> through out #he site were soil borings #7, 10 & 11. The originat soil <br /> below the system from new SB#2 to SB#$ found a 2.4' drop from the <br /> west to the east. This indicates that prior to the system being <br /> installed, the soils were excavated o#f. Old SB #10 found mottled soil <br /> at 5.5' with 2.4' of soil removed, mottling would have been at 3.1'. The • <br /> new SB#5 is in the approximate same located & mottled soil was <br /> found at 3' into the original soit. <br /> At the time of the inspection 2 systems were found at 2 different <br /> elevations 94.9 to 95.7 for the west system � 92.1 to 92.2 for the east <br /> system. To repair the system, the west system will need to be <br /> removed to the bottom of the trenches & backfilled weth washed sand <br /> to meet a 3' separation from the moftled soil (redox featuresj. This <br /> will require additional soi! boring � design. <br /> Thank You <br /> Steven 6. Schirmers <br />
