A. Based on the material passing the 3 inch (75 mm) sieve.

B. If field sample contained cobbles or boulders, or both, add "with cobbles or boulders, or both" to group name.

C. Gravels with 5 to 12% fines require dual symbols:

GW GM well graded gravel with silt GW GC well graded gravel with clay GP GM poorly graded gravel with silt GP GC poorly graded gravel with clay

D. Cu = D60 / D10 Cc = 30 2 / 10 60)

E. If soil contains 15% sand, add "with sand" to group name.

F. If fines classify as CL ML, use dual symbol GC GM or SC SM.

G. If fines are organic, add "with organic fines" to group name.

H. Sands with 5 to 12% fines require dual symbols:

SW SM well graded sand with silt SW SC well graded sand with clay SP SM poorly graded sand with silt SP SC poorly graded sand with clay

I. If soil contains 15% gravel, add "with gravel" to group name.

J. If Atterberg limits plot in hatched area, soil is CL ML, silty clay.

K. If soil contains 15 to < 30% plus No. 200, add "with sand" or "with gravel", whichever is predominant.

L. If soil contains 30% plus No. 200, predominantly sand, add to group name.

M. If soil contains 30% plus No. 200 predominantly gravel, add to group name.

N. PI 4 and plots on or above line.

O. PI < 4 or plots below line.

P. PI plots on or above line.

Q. PI plots below line.

Drilling Notes:

Blows/N value: Blows indicate the driving resistance recorded for each 6 inch interval. The reported N value is the blows per foot recorded by summing the second and third interval in accordance with the Standard Penetration Test, ASTM D1586.

Partial Penetration: If the sampler could not be driven through a full 6 inch interval, the number of blows for that partial penetration is shown as #/x" (i.e. 50/2"). The N value is reported as "REF" indicating refusal.

Recovery: Indicates the inches of sample recovered from the sampled interval. For a standard penetration test, full recovery is 18", and is 24" for a thinwall/shelby tube sample.

WOH: Indicates the sampler penetrated soil under weight of hammer and rods alone; driving not required.

WOR: Indicates the sampler penetrated soil under weight of rods alone; hammer weight and driving not required.

Water Level: Indicates the water level measured by the drillers either while drilling ( ), at the end of drilling ( ), or at some time after drilling ( ).

Moisture Content:

Dry: Absence of moisture, dusty, dry to the touch.

Moist: Damp but no visible water.

Wet: Visible free water, usually soil is below water table.
