NOTES - LOGS OF TEST HOLES
Test hole locations were detennined by compass bearing and pacing distances from known topographic points.
"Drilling Method" refers to the equipment utilized to advance the test hole. seven-inch outside diameter, continuous flight, hollowstem auger was utilized.
"S" under "Sample Type" indicates a Standard Penetration test (ASTM D-I586). The Standard Penetration sampler is 2 inches in outside diameter and 1 3/8 inches inside diameter.
"R" under "Sample Type" indicates a 3-inch outside diameter by 2.5-inch inside diameter sampler. The sampler is lined with I-inch high brass rings.
"B" under "Sample Type" indicates a bulk sample.
"Blows Per Foot" indicates the number of blows of a 140-pound hammer falling 30 inches required to drive the indicated sampler 12 inches.
!lNR" under "Blows/Foot" indicates that no sample was recovered.
"Dry Density PCF" indicates the laboratory detennined soil dry density in pounds per cubic foot.
"Water Content %" indicates the laboratory detennined soil moisture content in percent (ASTM D-2216).
"Unified Classification" indicates the field soil classification as per ASTM D-2488. When appropriate, the field classification is modified based upon subsequent laboratory tests.
Variations in soil profile, consistency, and moisture content may occur between test holes. SubsUlface conditions may also vary between test holes and with time.
