=======================
It
is to be noted that, whereas the test borings are drilled and sampled by experienced
drillers, it is sometimes difficult to record changes in stratification within narrow limits.
In the absence
of foreign substances, it is also difficult to distinguish between discolored
soils and clean soil fill.
Soil Conditions
Boring B-1 - The subsurface soil conditions consist
of an upper stratum of fine sand,
an intermediate stratum of clayey sand, and a deeper stratum of silty clay.
From the mudline
to an approximate depth of six (6) feet, an upper stratum of
medium sand with shells was encountered. Standard penetration values (N) obtained within
these soils ranged from one (1) to four (4) blows per foot. These soils are non-plastic and
contain between 12 and
23 percent silt and clay size particles as indicated by minus #200
sieve tests.
From six (6) feet below the mudline, to a depth
of 7.5 feet, an intermediate stratum
of clayey sand was encountered. A standard penetration value (N) obtained within these
soils
was two (2) blows per foot. These soils contain approximately 42 percent silt and clay
size particles as indicated by minus
#200 sieve tests.
From 7.5 feet below the mudline and extending
to a depth of nine (9) feet, a stratum
of silty clay was encountered. A standard penetration value (N) obtained within these soils
was four (4) blows per foot. These soils are high in plasticity as indicated by an Atterberg
limit test. The tested liquid limit was 53 percent and plasticity index
(PI) was 31. These
soils contain approximately 22 percent sand size particles as indicated by a minus
#200 sieve
test.
Boring B-2 - The subsurface soil conditions consist
of an upper stratum of fme sand,
intermediate strata
of clayey sand and silty clay, and a deeper stratum of sandy clay.
From the mudline
to
an approximate depth of six (6) feet, an upper stratum of fine
sand was encountered. Standard penetration values (N) obtained within these soils ranged
from zero (0) to one (1) blow per foot. These soils are non-plastic and contain between five
(5) and 14 percent silt and clay size particles as indicated by minus #200 sieve tests.
From six (6) feet below the mudline, to a depth
of 10.5 feet, intermediate strata of
clayey sand and silty clay were encountered. Standard penetration values (N) obtained
within these soils ranged from one (1)
to
11 blows per foot. These soils are low in
plasticity as indicated by Atterberg limit tests. Liquid limits ranged from 24 to 27 percent
and plasticity indicies
(PI) ranged from seven (7) to 12.

Professional Service Industries
=========================
From 10.5 feet below the mudline and extending to a depth of 13.5 feet, a stratum
of sandy clay was encountered. Standard penetration values (N) obtained within these soils
averaged
10 blows per foot. These soils are low in plasticity as indicated by Atterberg limit
test. The tested liquid limit was 34 percent and plasticity index
(PI) was 13. These soils
contain approximately
50 percent sand size particles as indicated by a minus #200 sieve test.
Boring B-3 - The subsurface soil conditions consist
of a stratum of silty clay.
From the mudline
to an approximate depth of 10.5 feet, an upper stratum of silty
clay was encountered. Standard penetration values
(N) obtained within these soils ranged
from zero
(0) to 11 blows per foot. These soils are high in plasticity as indicated by
Atterberg limit tests. Liquid limits averaged
68 percent and plasticity indicies (PI) averaged
29. These soils contain between one
(1)
and eight
(8)
percent sand size particles as
indicated by minus
#200 sieve tests.
Boring
B-4
- The subsurface soil conditions consist
of an upper stratum of clayey
sand and fme sand and a deeper stratum
of silty clay.
From the mudline to an approximate depth
of six (6) feet, an upper stratum of clayey
sand and fine sand
was encountered. Standard penetration values (N) obtained within these
soils ranged from zero
(0) to three (3) blows per foot. These soils are generally non-plastic
and contain between one
(1) and 34 silt and clay size particles as indicated by minus #200
sieve tests.
From six
(6) feet below the mudline and extending, a stratum of silty clay was
encountered. Standard penetration values
(N) obtained within these soils ranged from seven
(7) to 12 blows per foot These soils are high in plasticity as indicated by an Atterberg limit
test. The tested liquid limit was
77 percent and plasticity index (PI) was 34. These soils
contain approximately five (5) percent sand size particles as indicated
by minus #200 sieve
tests.
CONTAMINATION
ASSESSMENT
Analytical test results indicate concentrations of Total Petroleum Hydrocarbons
(TPH) in the four (4) composite soil samples collected from soil boring locations B-1, B-2,
B-3, and B-4. The levels
of TPH concentration encountered in the soil samples from soil
boring locations B-1 and B-2 are those typically associated with the biodegradation
of
naturally occurring organic matter and do not represent an adverse environmental concern.
