WATER LEVEL MEASUREMENT SYMBOLS
WL :Water Level WS :While Sampling
WCI : Wel Cave in WD :While Drilling
DCI :Dry Cave in BCR :Before Casing Removal
AB :After Boring ACR :After Casting Removal
Water levels indicated on the boring logs are the levels measured in the borings at the time indicated. In pervious soils, the
indicated levels may reflect the location of groundwater. In low permeability soils, the accurate determination of groundwater
levels is not possible with only short term observations.
DESCRIPTIVE SOIL CLASSIFICATION:
Soil Classification is based on the Unifed Soil Classification system and the ASTM Designations D-2487 and D-2488. Coarse
Grained Soils have more than 50% of their dry weight retained on a #200 sieve; they are described as:boulders, cobbles,
gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are described as:
clays, if they are plastic, and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and
minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse
grained soils are defined on the basis of their relative in-place density and fine grained soils on the basis of their consistency.
Example: Lean clay with sand, trace gravel, stiff (CL); silty sand, trace gravel, medium dense (SM).
