In <br /> sand,the indicated levels can be considered relatively reliable for most site conditions. In clay soils, it is not <br /> possible to determine the ground water level within the normal scope of a test boring investigation,except <br /> where lenses or layers of more pervious water bearing soil are present;and then a long period of time may be <br /> necessary to reach equilibrium. Therefore,the position of the water level symbol for cohesive or mixed soils <br /> may not indicate the true level of the ground water table. The available water level information is given at the <br /> bottom of the log sheet. <br /> IDESCIRIPTIVETERIMINOLOGY <br /> RELATIVE DENSITY CONSISTENCY <br /> TERM N60 Value(corrected) TERM N60 Value(corrected) <br /> Very Loose 0-4 Soft 0-4 <br /> Loose 5-8 Medium 5-8 <br /> Medium Dense 9—16 Rather Stiff 9—15 <br /> Dense 16—30 Stiff 16—30 <br /> Very Dense Over 30 Very Stiff Over 30 <br /> RELATIVE PROPORTIONS PARTICLE SIZES <br /> TERMS RANGE MATERIAL DESCRIPTION U.S.SIEVE SIZE <br /> Trace 0—5% Boulders Over 3" <br /> A little 5—15% Gravel Coarse 3"to%" <br /> Some 15—30% Medium %"to#4 <br /> Sand Coarse #4 to#10 <br /> Medium #10 to#40 <br /> Fine #40 to#200 <br /> Silt and Clay Determined by Hydrometer Test <br />
