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 />DESCRIPTIVE TERMINOLOGY <br />TERM <br />Very Loose <br />Loose <br />Medium Dense <br />Dense <br />Very Dense <br />RELATIVE DENSITY <br />No Value (corrected) <br />0-4 <br />5-8 <br />9-16 <br />16-30 <br />Over 30 <br />RELATIVE PROPORTIONS PARTICLE SIZES <br />TERMS <br />Trace <br />A little <br />Some <br />RANGE <br />0-5% <br />5 — 15% <br />15 — 30% <br />MATERIAL <br />Boulders <br />Gravel <br />Sand <br />CONSISTENCY <br />TERM No Value (corrected) <br />Soft 0-4 <br />Medium 5-8 <br />Rather Stiff 9 —15 <br />Stiff 16 — 30 <br />Very Stiff Over 30 <br />DESCRIPTION U.S. SIEVE SIZE <br />Coarse <br />Medium <br />Coarse <br />Medium <br />Fine <br />Over 3" <br />3" to /„ <br />3 " to #4 <br />#4 to #10 <br />#10 to #40 <br />#40 to #200 <br />Silt and Clay Determined by Hydrometer Test <br />
