EVALUATION OF SEDIMENT RECOVERY
COMMENCEMENT BAY NEARSHORE/TIDEFLATS FEASIBILITY STUDY
The formulation of the relationship between source loading and sediment
accumulation of problem chemicals is essential to the development of
sediment recovery scenarios. The following processes influence the sediment
concentration of contaminants:
Temporal changes in source input
Sediment accumulation and mixing
Biodegradation
Diffusive losses across the sediment-water interface.
An exact mathematical formulation of these processes would be extremely
complex and would require an extensive amount of data, much of which are not
available. The Sediment Contamination Assessment Model (SEDCAM) is a mass
balance equation that attempts to predict the sediment concentration of
contaminants in relation to source loading, sedimentation rates, mixing,
biodegradation, and loss across the sediment-water interface. The model
estimates the time required for sediment concentrations to decrease to
levels that are considered acceptable and is used to assess the potential
success of source control.
The rate at which sediments accumulate and the extent of mixing in
surface sediments influence natural dilution and attenuation of contaminant
input. Therefore, information on sediment accumulation and mixing processes
in a given problem area is essential to adequately predict how concentrations
of chemicals found in the surface mixed layer vary over time. The absence
of information on sediment accumulation and mixing in the Commencement Bay
nearshore/tideflats problem areas was identified as a major data gap during
the RI (Tetra Tech 1985). In order to expand the database, a sediment
profile survey was conducted as a part of the FS.
Total sediment accumulation comprises both natural "background"
particulates and participates derived from contaminated sources. In the
absence of contaminant input, the accumulation of natural sediments buries
contaminated surface sediments, and effectively decreases the toxicity of
the surface sediments. However, sediment mixing attenuates this effect by
mixing the deeper contaminated sediments upward to the surface. The
following variables are important in understanding the sediment accumu-
lation process:
Concentration of problem chemicals in recently deposited
material
A-l
-------
Concentration of problem chemicals in surface sediments
Sedimentation rate.
Depth of the surface mixed layer
Rate at which problem chemicals are lost because of bio-
degradation and diffusion.
The sediment recovery model uses the above parameters to predict contaminant
concentrations in surficial sediments as a function of time.
MODEL FORMULATION
The link between source and sink is illustrated schematically in Figure
A-l. The variation in contaminant concentration (C) in the surface mixed
layer with time (t) is derived from a mass balance described by the
differential equation:
dC CT * S C * S
- = kc * C (1)
dt D D
change in concentration = accumulation - burial - decay over time
where:
Cj = Concentration of contaminant in recently ieposited material
after source control (mg/g)
S = Rate of accumulation of solid material in the sediments (cm/yr)
D = Depth of sediments in the surface mixed layer (cm)
C = Chemical concentration in the surface mixed layer (mg/g)
kc = Combined first-order rate constant for contaminant loss by in situ
degradation and diffusive loss (1/yr).
The solution to this equation is:
-(kcD+S)t -(kcD+S)t
C = * CT * 1 - e Q + Cn * e D (2)
(S+kcD) l °
where:
t = time (yr)
CQ = Concentration of contaminant in the surface mixed layer at t=0
(mg/g).

DETERMINATION OF INITIAL CONTAMINANT CONCENTRATION ON SEDIMENTS (CQ)
The parameter CQ is the concentration of a chemical contaminant in
surface sediments at time = zero. The areal and depth distribution of
problem chemical concentrations in the study area sediments was determined
during the RI (Tetra Tech 1985) and the FS field study. During this study
of sediment recovery scenarios, the maximum concentration of a problem
chemical in surface sediments from a problem area was used to calculate
sediment recovery time. If dredging is conducted, CQ must be represented by
the contaminant concentration in the sediment horizon exposed by dredging
activity. The determination of other parameters (i.e., sedimentation rate,
mixing depth, and decay constant) is more complex, and is described in the
following section.
PARAMETER IDENTIFICATION
Sedimentation rate, mixing depth, chemical persistence (i.e., decay
constant), and chemical loading are important processes controlling the
concentration of contaminants in surficial sediments. During the FS, high-
resolution sediment core profiles were collected for the purpose of
evaluating the extent of sediment mixing and sediment deposition using
excess Pb-210 techniques. Chemical persistence was also evaluated during
the FS. The approach and resulting decay constants are briefly summarized
here. In addition, simplifying assumptions that eliminate the need to
specify all parameters which compose Cj are presented.
Sediment Accumulation and Mixing Layer
Sediment accumulation rates are necessary to determine the time that
will elapse between controlling sources of contamination and reducing
surficial sediment concentrations (i.e., the response time). The sedimenta-
tion rate S (cm/yr) is related to the mass accumulation rate R (mg/cm2/yr)
by the following expression:
R = S * (1-p) * d (3)
where:
p = porosity of sediments (unitless)
d = dry density of sediment (mg/cnv*).
A-4
-------
The mixing layer depth can also have a major influence on the response time
of contaminant concentrations in sediments after sources have been con-
trolled. The value of the depth of the surface mixed layer is important to
the application of SEDCAM because it effectively defines the size of the
reservoir that will attenuate concentration changes brought on by source
control. This is illustrated by considering the hypothetical case where the
mixed layer depth is measured to be zero. In terms of the model, this means
that any change in the concentration of a contaminant in incoming sediments
is instantly registered in the concentration of surface sediments.
The technique of measuring changes in excess Pb-210 activity with depth
is often used to estimate sediment accumulation rates and mixing layer
depths in nearshore sediments because lead has a strong particle affinity.
In addition, the half-life of the isotope (22 yr) is appropriate to the time
scale of sediment accumulation. The evaluation of excess Pb-210 sediment
profiles provided the basic framework for describing the depositional
environment in the waterways of Commencement Bay.
A hypothetical and idealized profile of log-transformed Pb-210 data is
presented in Figure A-2 to illustrate how the sedimentation rate and depth
of the mixed layer are derived from excess Pb-210 activity data. Mixing of
near-surface deposits attenuates the observed decay in excess Pb-210
activity and occurs as a result of several factors, including the activity
of benthic organisms. In Figure A-2, the horizontal dashed line locates the
interface between sediments and the surface mixed layer. The decrease in
excess of Pb-210 activity below the mixed layer can be related directly to
the half-life of Pb-210. The slope of the line relating excess Pb-210
activity to sediment depth can be directly related to the sediment accumula-
tion rate.
The accuracy of the technique depends in part on constant sedimentation
and Pb-210 accumulation rates. Factors unique to the environmental setting
of the Commencement Bay waterways complicated the application of this
technique. These factors include dredging activities, shipping traffic,
sediment slumps and slides, as well as temporal changes in depositional
rates influenced by anthropogenic activities. Because of these complica-
tions, sedimentation rates derived from Pb-210 techniques were verified with
secondary techniques. The most commonly used secondary technique involved
measuring the thickness of sediments overlying a distinctive feature in the
core, such as a dredging horizon or chemical interface.
Sedimentation rates determined for the waterways of Commencement Bay
ranged from 0.14 to 1.77 cm/yr, while the depths of the mixed layers ranged
from 0 to 20 cm (see Table A-l). A mixed layer depth of 10 cm was assumed
to best represent the average mixed layer depth in the waterways.
Chemical Persistence
SEDCAM incorporates a chemical-specific first-order rate constant (kg)
to represent the rate of total loss of contaminants from sediments that is
not accounted for by burial. The formulation of loss as first-order decay

assumes that loss is only a function of chemical concentration. The
processes considered most likely to cause contaminant losses from sediments
are microbial degradation and diffusion into the overlying water column.
In situ degradation and diffusion can effectively reduce sediment concentra-
tions when estimating recovery times. Microbial mediated degradation is
only a significant term for the most degradable of organic chemicals and may
be formulated as a zero- or second-order equation. The assumption of first-
order decay represents a generalized simplification of the degradation
process. Diffusive losses are considered significant only for the most
soluble of problem chemicals.
The approach used was to select the lowest, most environmentally
protective decay rate values. Such kc values will result in upper estimates
of recovery times for problem areas. Details of the derivation of the
chemical-specific first-order decay constants (kc) used are presented in
Section 4.0 of Tetra Tech (1987).
Incoming Contaminant Concentration
The parameter Cj, the incoming contaminant concentration, is the
concentration of a problem chemical in recently deposited sediments after
source control. SEDCAM is used to evaluate sediment recovery following a
reduction of Cj as a result of source control. Because the value of Cj is
difficult to determine, the formulation of the parameters depends on the
amount of information available and the applicability of the simplifying
assumptions. Cj can be formulated as a function of the following variables:
Source loading prior to source control
Fraction reduction in loading due to source control measures
Fraction of contaminant lost in transit between the point of
discharge and the point of deposition
Depositional area
Sedimentation rate.
However, simplifying assumptions that eliminate the need to specify all of
the parameters noted are desirable.
In many cases, a steady-state assumption may be applied (i.e., that the
system was in steady-state prior to implementation of source control
measures). This simply means that the input rate equals the removal rate,
so that the concentration of the contaminant in the well-mixed box (see
Figure A-l) does not vary over time. The steady-state assumption is a
useful simplification because the incoming contaminant concentration (Cj)
does not have to be quantified and can be represented by the equation:
C, CQ * fL Ğ 'S * kc°) (4)
A-8
-------
For the cases where kc = 0, Cj can be directly determined from CQ and the
degree of source control, f^ Thus, Equation 4 becomes:
Ci=C0*fL (5)
In general, there are three cases that represent the relationship
between source loading and sediment accumulation prior to source control:
Source loading is increasing over time, or surficial sediment
concentrations have not yet increased to levels supported by
accumulating contaminated particles
Source loading is decreasing over time, or surficial sediment
concentrations have not yet adjusted to recent decreases in
contaminant loading
Source loading is in steady-state with sediment accumulation.
Temporal trends in loading may be derived from source loading data, disposal
chronologies, and sediment profiles of problem chemicals. If source loading
has either increased or decreased recently, the steady-state approximation
(i.e., Cj = CQ) will underestimate or overestimate the concentration in
recently deposited sediments.
Estimating CT from source loading data was not practical in the
application of SEDCAM to the waterways of Commencement Bay for several
reasons:
Source loading data are only available for selected chemicals
Source loading data tend to be biased toward selected input
pathways (i.e., storm drains and industrial outfalls)
Contaminant sources are highly variable over time, and thus a
large number of measurements must be made to estimate average
loading.
Therefore, the steady-state assumptions were applied and Cj was formulated
as a function of CQ, as in Equations 4 and 5. For the indicator chemicals
used in this study, biodegradation was assumed to be negligible (i.e., kc=0)
over the time periods of concern. Therefore, prior to implementation of
source controls, Equation 5 suggests that CpCg, and after source controls
are implemented, CpCg*^, where f|_ is degree of source control assumed to
be feasible.
APPLICATION
Several important pieces of information may be derived from the
sediment recovery scenarios developed from the application of SEDCAM:
Recovery time if sources of contamination are completely
eliminated
A-9
-------
The reduction of contaminant concentrations in the surface
mixed layer over any given time period after implementation
of source control measures
The degree of source control required to effect sediment
recovery in the long term
Long-term effect of not controlling sources.
Recovery times predicted for complete source elimination provide a framework
for evaluating the effectiveness of source control and the relative severity
of contamination by different problem chemicals. The degree of source
control required to effect sediment recovery in a reasonable timeframe will
be greater than that required for long-term recovery because of mixing of
the surface sediments. The added time constraint must be compensated for by
more extreme source control measures. In some cases, recovery in a
reasonable timeframe may not be possible even with complete source elimi-
nation because chemical concentrations in sediments are too high or the
sediment accumulation rate of clean material is too low. The long-term
effect of not controlling sources is only of interest for chemicals
associated with sources that are not in steady-state with sediment accumu-
lation (i.e., sources that are relatively new, or have displayed pronounced
increases or decreases in loading rates).

CLAMSHELL DREDGES
Clamshell dredges are mechanical dredges. They are crane-operated
devices with a bucket attached to a cable and pulley mechanism at the end of
a boom. Anchors and spuds are secured, then the open bucket is dropped from
the dredge into the sediments. Material is dislodged and held in the bucket
by closing the jaws. The bucket is then raised from the water and swung
over the temporary storage area and released. As the bottom of the waterway
is dredged to the desired depth to remove contaminated sediments, the
anchors and spuds are released, the dredge is moved forward, and the process
is repeated. Clamshell dredges are barge-mounted or track-mounted (land-
based), depending on the accessibility of the site.
Effectiveness
Clamshell buckets range in capacity from 1 to 18 yd^ and have an
effective working depth of approximately 100 ft. Clamshell dredges have
limited production rates, typically 30 to 60 buckets/h (U.S. Army Corps of
Engineers 1985), but have an inherently high degree of position and depth
control. For these reasons, clamshell dredges are particularly effective
for removal of contaminated sediments in confined areas (e.g., around docks
and piers). They can effectively remove all but the most cohesive materials
at in situ densities.
The greatest disadvantage of the clamshell dredge is the excessive
suspended solids generated from agitation of the sediments. Watertight
clamshell buckets were developed by the Japanese and the U.S. Army Corps of
Engineers to minimize the resuspension of solids in the water column. This
type of bucket is sealed (tongue-in-groove) when the jaws close and the top
of the bucket is covered to minimize the loss of dredged material as the
bucket is pulled up through the water column. Studies performed by the
U.S. Army Corps of Engineers comparing watertight and conventional clamshell
buckets showed a 30-70 percent decrease in suspended solids generation
throughout the water column with the watertight bucket (U.S. Army Corps of
Engineers 1985). The studies also suggest that watertight buckets produce a
higher level of resuspension near the waterway bottom. This may be
attributed to the shock waves of water that precede the watertight bucket.
Conventional clamshell buckets can be converted to watertight buckets with
minor structural modifications (U.S. Army Corps of Engineers 1985).
Implementation
In general, it is recommended that clamshell dredges, if used to remove
contaminated sediments, have large buckets to minimize the resuspension of
B-l
-------
solids during dredging operations. Large clamshell dredges are a well-
established technology and are readily available in Puget Sound and the
Pacific Northwest.
Conclusions
Closed bucket clamshell dredges are retained for further evaluation.
DRAGLINE DREDGES
Dragline dredges are mechanical dredges. They are crane-operated
devices with a drag bucket connected by a cable to the boom. The boom is
extended and the bucket is thrust into the sediments. The bucket is then
filled by pulling it towards the crane through the material to be removed.
Dragline dredges are barge-mounted or land-based, depending on the location
of the dredging site.
Generally, a dragline dredge offers a longer reach than a clamshell
dredge operated by the same crane. However, control of the dragline is
inferior to that of the clamshell. A variety of bucket sizes and boom
lengths are available, depending on the type of material to be removed and
the depth of sediment to be excavated. The maximum digging depth of a
dragline is approximately equal to half the length of the boom, while the
reach is slightly greater than the length of the boom (U.S. EPA 1982).
Effectiveness
Production rates are somewhat limited with dragline dredges, and
resuspension of solids due to agitation of the sediments and bucket leakage
tends to be considerable. In general, the medium and larger buckets tend to
be more efficient and generate less suspended solids.
Implementation
Availability of dragline dredges is good in the Pacific Northwest.
Conclusions
Dragline dredges are not retained for further evaluation.
BUCKET LADDER DREDGES
A bucket ladder dredge is a mechanical dredge. It consists of a
submersible ladder supporting a continuous chain of buckets that rotates
around two structurally held tumblers. As the buckets rotate around the
bottom of the ladder, they scoop up the material to be removed and transport
it to the top of the ladder, where it is discharged into a storage area on
the dredge. Bucket ladder excavation has its most common application in
mining, quarry, and sand and gravel operations.
B-2
-------
Effectiveness
Although production rates for these types of dredges are generally
higher than for other mechanical dredges, they tend to have higher capital
costs and produce excessive suspended solids during operation. Resuspension
of solids results from mechanical agitation of the sediments and leakage of
dredged materials from the buckets. For these reasons, bucket ladder
dredges are not recommended for dredging of contaminated sediments unless
the dredging area is within a dewatered portion of a waterway (e.g.,
Wheeler-Osgood). Development of watertight buckets is being considered by
dredging manufacturers to reduce the suspended solids generated by this type
of dredge during transport through the water column. However, this improve-
ment would not mitigate suspended solids generated by agitation of the
sediments.
Implementation
Bucket ladder dredges are generally used for sand and gravel mining,
and are not applicable to contaminated sediments. Availability in the
United States is limited.
Conclusions
Bucket ladder dredges are not retained for further evaluation.
DIPPER DREDGES
Dipper dredges use mechanical dredges similar to backhoes. A bucket
attached to a long boom is forcibly thrust into the sediments to be removed.
Sediments are dislodged by the violent mechanical action, generating
considerable turbidity due to agitation of sediments.
Effectiveness
Production rates for dipper dredges are comparable to other types of
mechanical dredges. Dipper dredges have their most effective application
when excavating materials of soft rock and dense sedimentary deposits (e.g.,
clay or glacial till). Dipper dredges tend to produce higher levels of
suspended solids in the water column and are more expensive to use than
other mechanical dredges (U.S. Army Corps of Engineers 1985).
Implementation
Dipper dredges are not considered a very effective method of removing
contaminated sediments due to the additional suspended solids control
measures necessary and the potential for dissolved contaminants to migrate
from the site. Dipper dredges probably have little applicability for the
Commencement Bay problem areas.
B-3
-------
Conclusions
Dipper dredges are not retained for further evaluation.
BUCKETWHEEL DREDGES
The bucketwheel has characteristics of both mechanical and hydraulic
dredges. A bucketwheel dredge head mechanically dislodges the sediments and
a submerged pump conveys the dredged material from the bucketwheel to the
discharge point via a suction line. Dredged material is discharged to
hoppers on the dredge vessel, discharged to barges tethered to the dredge
vessel, or transported through floating or submerged pipelines to the
disposal area. Material is dislodged when buckets are pushed into the
sediments and then lifted, filled with sediments, as the bucket wheel
rotates through the excavation.
Bucketwheels are classified as suction or transport, depending on the
location of the hydraulic transport system. The suction chamber on a
suction bucketwheel is located just behind the cutting buckets in the lower
wheel area. This design allows immediate transport of loosened material and
probably minimizes the resuspension of sediments. The transport bucketwheel
is similar to the bucketwheels used on land in that the suction chamber is
located at the highest point of the wheel.
Effectiveness
Bucketwheel dredges are large vessels with very high production rates,
averaging approximately 2,100 yd*/h (range 845-3,965 yd^/h). Production is
dependent primarily on sediment type, which will dictate the type of
bucketwheel, cutting method (i.e., vertical or horizontal cut), and anchor-
ing arrangement. Dredging depths up to 330 ft are possible with floating
carrier bucketwheel systems. In general, bucketwheels can effectively
dredge sediment types ranging from moderately hard rock to adhesive soils
(Hahlbrock 1983). However, different sediment types will demand specifi-
cally designed wheels.
Transport bucketwheels were determined to achieve higher production
rates than suction systems under all simulated operating cases. This is
explained by the fact that entry into the suction chamber is aided by the
force of gravity, despite the buoyancy of the soil underwater (Hahlbrock
1983). Significant sediment resuspension is expected due to action of the
bucketwheel in water and sediments.
Implementation
The underwater bucketwheel was developed for application in marine
mining and dredging based on decades of experience with "dry" bucketwheel
excavators. Thorough testing of prototypes have proven that they can be
used successfully for these applications (Hahlbrock 1983). Bucketwheels are
used worldwide for deep-sea mining projects. Feasibility of this technology
for Commencement Bay also depends on the availability of the equipment and
production costs (cost/yd3). Based on a review of literature and related
B-4
-------
case studies, it appears that bucketwheels have not been used in the Pacific
Northwest.
Conclusions
Bucket ladder dredges are not retained for further evaluation.
SUCTION DREDGES
The plain suction dredge is the simplest type of hydraulic dredge,
relying entirely on the suction created by the centrifugal pump to dislodge
and transport the sediments. Sediments and dilution water are vacuumed off
the waterway bottom through the suction head and the slurry is discharged to
a stern-mounted pipeline leading to the disposal point. By adding devices
to dislodge sediments, the suction dredge can be converted to other types of
hydraulic dredges (e.g., cutterhead, dustpan, cleanup). The suction head is
mounted at the end of an adjustable ladder. Depth and position of the
suction head are controlled by cables attached to the ladder.
Effectiveness
Plain suction dredges are most effective in the removal of free-flowing
materials such as sands, gravels, and unconsolidated sediments. Since no
mechanical device is attached to the suction head, hard cohesive materials
such as clay and firm native bottom sediments are not readily removed by
this method. Plain suction also minimizes turbidity generated by mechanical
agitation of the sediments. Slurries of 10 to 15 percent solids by weight
can be achieved in appropriate applications (Hand et al. 1978).
Implementation
The plain suction dredge is a pipeline cutterhead dredge with the
cutterhead removed. It will not be considered as a separate technology, but
instead as a modification of a preferred technology.
Conclusions
Plain suction dredges are not retained for further evaluation.
PIPELINE CUTTERHEAD DREDGES
The cutterhead dredge is a modification of the plain suction dredge.
The cutterhead has spiral blades shaped in the form of a basket. The
cutterhead is attached to the end of the suction pipeline, which is mounted
on an adjustable ladder to facilitate depth control of the dredge head. As
the cutterhead rotates, sediments are dislodged allowing transport through
the suction line. A secondary purpose of the cutterhead is to screen out
debris that may enter and plug the suction line. There are many types of
cutterheads and modifications to cutters to allow dredging in different
types of materials. Cutter diameters range from 2 to 10 ft.
B-5
-------
Walking spuds are a preferred design option because the cutterhead
dredge is not self-propelled. Walking spuds advance the dredge up to 40 ft
without taking a step.
Effectiveness
Production rates for cutterhead dredges are governed principally by the
pipeline diameter and the dredge pump capacity. Production rates range from
approximately 71 yd-Vh for a small dredge (6 in) up to 3,600 yd-Vh for a
large dredge (30 in) (U.S. Army Corps of Engineers 1985). In general,
dredging depth and cut depth increase with dredge size. The maximum
dredging depth for a conventional large cutterhead is 50 ft below water
level. For dredging depths in excess of 50 ft, modification of the dredge
ladder is required (U.S. Army Corps of Engineers 1985). The maximum cut
depth for a large cutterhead is 36 in. Large set and very thick cuts should
be avoided since they will bury the cutterhead. This may create excessive
suspended solids if the suction cannot remove all of the material that was
dislodged (U.S. Army Corps of Engineers 1985).
A properly designed cutterhead will dislodge the bottom sediments and
guide them towards the suction efficiently. However, some resuspension of
solids is generated from mechanical agitation of the bottom sediments. The
level of resuspension from cutterhead operations is a function of the
quantity of material dislodged but not removed by the suction head. Field
studies indicate that levels of resuspended solids are highly variable,
depending primarily on operational controls. Technology development has
emphasized cutterhead designs that reduce resuspension of solids. This is
especially important in dredging contaminated sediments.
Implementation
The cutterhead dredge is the most widely used dredge in the United
States and in the Pacific Northwest (U.S. Army Corps of Engineers 1985).
Their widespread use and availability make them among the least expensive
dredging methods. Initial mobilization and set-up costs are considerable
because conventional cutterheads are not self-propelled and must therefore
be transported between dredging locations by towboats. The addition of
walking spuds is a preferred modification. These units are economically
feasible only when quantities to be dredged are sufficient to amortize the
initial costs to obtain a competitive average cost per cubic yard.
Conclusions
Pipeline cutterhead dredges are retained for further evaluation.
DUSTPAN DREDGES
The dustpan dredge is a modification of the suction dredge. The
dustpan has a widely flared dredging head upon which several high-pressure
water jets are mounted. The water jets dislodge the bottom sediments, which
are then removed by suction through the dustpan head as the dredge is moved
B-6
-------
ahead into the excavation. Like the suction and cutterhead dredges, this
unit is not self-propelled and must be moved along by winches or a towboat.
Effectiveness
The dustpan is most effective in removal of free-flowing granular
sediments like sands and gravel. This dredge was developed by the U.S. Army
Corps of Engineers to maintain navigation channels in uncontrolled rivers
such as the Mississippi River (U.S. Army Corps of Engineers 1985).
Typically, slurries of 10 to 20 percent solids by wet-weight are achieved
with this type of dredge. The dustpan dredge is not recommended for use in
waterways with fine-grained sediments because pressure from the water jets
creates excessive turbidity. However, the dredge may be operated with low
or no water pressure to minimize turbidity. Clogging of the suction line
may result if the dustpan is used to dredge sediments with a high clay
content (U.S. Army Corps of Engineers 1985). Most dustpan dredges have low
discharge pressures and are not well suited or designed to transport
slurries distances over 1,000 ft without the assistance of a booster pump
(U.S. Army Corps of Engineers 1985). The major advantage with dustpan
dredges is that they are able to excavate very deep cuts, up to 6 ft in a
single pass (U.S. Army Corps of Engineers 1985), which may help to expedite
projects. All dustpan dredges are classified as "large," with discharge
line diameters of 30 in or greater.
Implementation
Due to the specific design purpose of the dustpan dredge, there are
several limitations to its application.
Conclusions
Dustpan dredges are not retained for further evaluation.
HOPPER DREDGES
Hopper dredges are large, self-propelled, seagoing ships with sediment
containers called hoppers. These may be designed with barge-type hulls or
molded hulls similar to ocean vessels (U.S. Army Corps of Engineers 1985).
Unlike most hydraulic dredges, sediments are pumped and contained on board
these vessels rather than discharged to a barge or transported through a
pipeline. Hopper dredges also differ from other hydraulic dredges in that
these vessels move ahead of the excavation, dragging the dredged heads,
rather than pushing them into the excavation, as is typically the pro-
cedure. Suction-created by centrifugal pumps located on the dredge removes
sediments from the channel bottom and raises them through the draglines.
Dredged materials are then discharged into the hoppers.
Hopper dredges are generally classified into sizes according to hopper
capacities: large class hoppers have capacities of >6,000 yd3, medium class
hoppers have capacities of 2,000 to 6,000 yd3, and small hoppers have
capacities of 500 to <2,000 yd3 (U.S. Army Corps of Engineers 1985). The
pumping rates range from 15 to 150 yd3/min (3,030 to 30,300 gal/min).
B-7
-------
Hopper dredges have a maximum dredging depth of approximately 60 ft, and a
minimum dredging depth of approximately 10 ft depending on the fully loaded
draft depth.
Effectiveness
Hopper dredges are most effective for dredging deep, rough-water
shipping channels and they are one of the few dredges capable of dredging
waterways that are sloped or vary in elevation. Hopper dredges have good
maneuverability, but cannot dredge sediments from around piers, docks, and
other structures. Since hopper dredge heads are capable of removing only a
few inches of sediment, successive passes over the same area may be neces-
sary to achieve the desired dredging depth.
Normally, as the hopper is filled, overflow water is discharged at the
dredge site allowing solids to settle and concentrate. This is usually not
acceptable when removing contaminated sediments. When the economical load
is achieved, the hopper is considered to be full. The economical load is
specified as the maximum overflow pumping time that allows the greatest
amount of solids accumulation in the hopper considering pumping and non-
pumping times (travel to and from the disposal site) of the dredging cycle
and the volume of solids that are hauled to the disposal site (no overflow
loss) (U.S. Army Corps of Engineers 1985).
Implementation
When dredging contaminated sediments, hoppers are considered full at
the point of overflow (assuming no overflow is permitted). Therefore, it is
unlikely that an economic load will be achieved for these conditions.
Typical slurries of 20 percent solids are produced with no overflow as
compared with an average of 70 percent solids in an economic load. This
drastically impacts the economical feasibility of this method due to the
additional trips to the disposal site and increased volume of material to be
treated and or disposed. Hopper dredges have often proven to be the most
economical type of dredge when the disposal sites are not within economical
transport distances using pump and pipeline systems. These two methods may
become more comparable when handling contaminated sediments, which necessi-
tates less productive operation of hopper dredges.
Availability of small and medium hopper dredges is good in the Pacific
Northwest. They can be mobilized and initiate dredging in relatively short
periods of time (U.S. Army Corps of Engineers 1985).
Conclusions
Hopper dredges are retained for further evaluation.
PORTABLE DREDGES (MUD CAT)
The U.S. Army Corps of Engineers defines "portable" dredges as those
that can be transported intact over existing roads or that are constructed
in a modular fashion for easy dismantling and transportation (Clark 1983).
B-8
-------
Weight and capacity are excluded from the definition because these factors
are said to be too arbitrary. Dredges are not considered portable if they
must be transported via water, either by barges or under their own power.
Mud Cat dredges are portable hydraulic dredges manufactured by a
separate division of National Car Rental Systems Inc. (Clark 1983). The Mud
Cat is the most widely known and used portable dredge and is available in
several models. Dredging depths range from 10 to 25 ft and production rates
range from 60 to 200 cubic yards per hour. The Mud Cat (SP-810) is equipped
with a centrifugal pump mounted directly behind the 8-ft horizontal auger.
The pump and entire cutterhead can be buried in the sediments to facilitate
high solids/low dilution pumping (U.S. EPA 1982).
Effectiveness
The Mud Cat has a retractable mud shield surrounding the cutter
equipment for greater suction efficiency and minimal sediment resuspension.
Low turbidity production of the Mud Cat makes this technology particularly
applicable for removal of contaminated sediments. Production rates range
from 50 to 130 yd3/h.
Implementation
Portable dredges have their greatest application in shallow or isolated
waterways. Their characteristically low draft depths (under 2 to 6 ft)
enable them to dredge sediments in shallow waters, however dredging depth is
limited to 15 ft or less. Maneuverability is excellent with their relative-
ly small size, that enables them to operate efficiently in isolated or
congested waterways. Mud Cat dredges are available in the Pacific North-
west and their portability allows for easy transport via truck or air (U.S.
Army Corps of Engineers 1985). Due to limited dredging depths, use of Mud
Cats in Commencement Bay is restricted to intertidal areas or during low
tides.
Conclusions
Mud Cat dredges are retained for further evaluation.
SPECIAL DREDGE HEAD ADAPTATIONS
The primary focus on development of special head adaptations is the
design of systems that remove sediments at high solids concentrations and/or
minimize the resuspension of sediments. These systems typically have low
production rates, although when dredging contaminated sediments, this
feature is usually of secondary importance to reducing turbidity or achieving
high solids concentration. Since many of these special head adaptations are
relatively new, there may be many unknowns concerning their applications and
limitations. Additional research, development, and experience may be
necessary to fully define their usage. Among the most noteworthy special
head adaptations discussed herein are the DREX, the cleanup, the refresher
system, and the waterless.
B-9
-------
DREX Head
The DREX head was developed by the Japanese company Mitsubishi Heavy
Industries Ltd. Unlike most hydraulic dredges with a fixed head on an
adjustable ladder, the DREX head allows the suction mouth to move laterally
with respect to the dredge head and ladder. Once the ladder swings through
an arc removing sediments, the suction mouth can be moved prior to returning
to the ladder. This allows dredging in parallel arcs rather than intersect-
ing arcs as is the procedure for conventional cutterheads. Parallel arcs
are a more efficient tracking pattern since there is essentially no dead-
heading in the dredging operation. For this reason, use of the DREX head
increases solids content of sediment slurries because pumping of excess
water as the dredge head passes over previously dredged areas has been
eliminated. Use of the DREX head will reduce the total volume of slurry to
be treated and/or disposed, but it does not appear to have any significant
advantage over other conventional hydraulic methods in minimizing the
resuspension of sediments.
Cleanup System
The Cleanup system, developed by the Japanese company Toa Harbor Works,
is a unique method for dredging highly contaminated sediments. Design
emphasis for the Cleanup system was maximum control of turbidity, with
secondary importance on maximizing the solids content of the slurry. The
Cleanup head consists of a shielded auger mounted on a ladder at the front
end of a pipeline dredge. As the ladder moves through the excavation, the
shield guides the sediments towards the suction of a submerged centrifugal
pump (U.S. Army Corps of Engineers 1985). Resuspension of solids is
minimized by shielding the auger with a wing that adjusts vertically,
enabling the head to maintain contact with the surface sediments and
preventing the sediments outside the head from being influenced by the
turbulence within the head. The dredging operation is monitored by sonar
devices that indicate elevation and by underwater televisions that observe
effectiveness of the turbidity controls. The Cleanup system has proven
effective at removing contaminated sediments with minimal resuspension of
solids and with high solids concentrations. Suspended solids concentrations
around the Cleanup system ranged from 1.7 to 3.3 mg/L at the sediment
surface to 1.1 to 7.0 mg/L at 10 ft above the suction equipment, relative to
background near-surface levels of less than 40 mg/L (U.S. Army Corps of
Engineers 1985). These levels of suspended solids are approximately one-
fiftieth of those associated with conventional hydraulic dredging methods.
Since the Cleanup system is a Japanese manufactured system, its availability
in the United States may be limited. Domestic marketing is likely in the
near future due to the system's compatibility with existing American-made
equipment (U.S. Army Corps of Engineers 1985). Limited availability of the
Cleanup system is likely to result in higher mobilization and initial costs
for this method.
Refresher System
The Refresher system is a modification of the cutterhead recently
developed by the Japanese. The Refresher uses a helical-shaped gather head
B-10
-------
to feed the sediments into the suction. It is equipped with a curve to
reduce resuspension of sediments. The dredge ladder, articulated to keep
the head level with the waterway bottom, facilitates dredging over a wide
range of depths. Results of comparison tests in similar material show the
Refresher system generates one-fifteenth of the total resuspended solids
generated by the operation of a conventional cutterhead (U.S. Army Corps of
Engineers 1985). Since the refresher is a Japanese-manufactured system, its
availability in the United States may be limited. Domestic marketing is
likely in the near future due to the system's compatibility with existing
American-made equipment (U.S. Army Corps of Engineers 1985). Limited
availability of the Refresher system is likely to result in higher mobiliza-
tion and initial costs for this method.
Waterless Dredge
The Waterless dredge was developed by the American firm, Waterless
Dredge Company, for the removal of sludges from lagoons with minimal water
content. The dredge head is equipped with a shrouded "roll-over" cutter and
a submerged centrifugal pump. As the cutterhead is moved through the
excavation, sediments displace the water in the cutterhead and block entry
of water into the dredge pump inlet. At the limit of the cut in one
direction, the cutterhead rolls over 180 degrees so that the face of the
cutterhead is open to receive sediments in the return direction. The
Waterless dredge continues to be field-tested and its application in removal
of contaminated sediments has been limited. It is reported that the
Waterless dredge can pump slurries containing less than 10 percent water by
volume with little resuspension of sediments.
BACKHOES AND LOADERS
Backhoes are barge-mounted or operated from land. However, their
lateral reach is quite limited and their vertical reach restricted to the
boom length. Backhoes normally used for subsurface excavation are capable
of reaching 40 ft or more below the level of the machine. Additionally,
backhoes can operate in shallow water up to several feet to provide access
for larger or barge-mounted dredging equipment.
Loaders are used to excavate loose or soft materials in a limited
vertical range of a few feet above and below grade. Since loaders must be
operated within close proximity to the material being removed, barge-mounted
and land-based equipment are not usually practical. Loaders may be practi-
cal in shallow water, if material to be removed is sufficiently loose or
soft. Loaders may also be useful for removing sediments from dewatered
portions of a waterway (e.g., potentially, Wheeler-Osgood).
Effectiveness
In general, the production rates of backhoes and loaders are comparable
to those of other mechanical dredges. However, suspended solids in the
water column generated from the mechanical agitation of sediments is
considerable with these types of dredges.
B-ll
-------
Implementation
Backhoes (power shovels) and front-end loaders (bucket loaders and
tractor shovels) have limited application in the removal of sediments
contaminated with hazardous materials. They are more practical to excavate
and load dredged materials from a temporary storage area or dewatered site,
and therefore have little applicability for the problem areas of Commence-
ment Bay.
CAPPING
There are three overall groups of cover materials: inert materials,
active materials, and synthetic liner materials. Inert materials include
sand, silt, and clay and may be fine-grained, coarse-grained, or uncon-
taminated dredged spoils. Active cover materials include limestone,
greensand, oyster shells, alum, alumina, ferric sulfate, and gypsum. The
function of an active cover material as opposed to an inert material is to
react with the contaminant to neutralize or detoxify it. Specific active
cover materials should be selected on the basis of the contamination
present. Neutralizing acids can be accomplished with limestone, oyster
shells, or greensand. Bases can be neutralized with ferric sulfate or
alum. Gypsum or. ferric sulfate can be used for metal precipitation, while
alumina is useful for fluoride removal. Active cover materials can be
applied alone or with inert materials. However, care must be taken during
placement of active cover materials because they can harm biota outside the
contaminated area.
Synthetic liners are available in a variety of materials. Liners must
be selected on the basis of their compatibility with the contaminated
sediments and their ability to withstand temperature and seawater effects.
Synthetic liners such as butyl rubber and chlorinated polyethylene are not
compatible with oils and hydrocarbon solvents.
Effectiveness
The effectiveness of different cover/capping materials depends on a
number of factors. The principle determinants for inert and active covering
materials are 1) turbidity and dispersion generated during application of
the material; 2) impacts on benthic organisms; 3) scouring and resuspension
of cover material once in place; and 4) resistance to leaching of contami-
nants. Turbidity and dispersion are a function of the delivery system used
to place the cover material on the bottom. Impacts on biota are also
directly related to the method of material delivery, the area! extent
covered, and the toxicity of the material (particularly for active cover
materials). The ability of the cover material to be recolonized without
contaminant bioaccumulation depends on the type of cover material, its
resemblance to natural sediments, the thickness of the cap (it must be thick
enough to keep burrowing organisms from reaching the contaminated sedi-
ments), and the potential for contamination leaching through the cover.
There is also concern that biological organisms [e.g., deep burrowing shrimp
(Pemberton et al. 1976)] can penetrate the cap, enhancing contaminant
transport.
B-12
-------
The susceptibility to scouring and resuspension of cover materials is
related to the particle size and shape, slope of the bottom, angle of repose
of the cover material, degree of material cohesiveness, and the flow
dynamics. The diffusion of chemical contaminants through the cover material
is governed by the thickness of the cap, permeability of the capping
material (e.g., grain size, sorptive properties), and the mobility of the
individual problem chemical(e.g., particle affinity, solubility, persis-
tence) .
Besides these controlling influences on the effectiveness of cover,
active cover materials must also remain in place long enough to react with
and treat the contaminated sediments. Gypsum and limestone tend to form a
cement-like cover that resists erosion. Ferric sulfate, alumina, and alum
are fine-grained and susceptible to erosion, while oyster shells and
greensand are the most susceptible to scour. Inert cover materials can be
mixed with the active materials to add erosion resistance, although effect-
ive interaction with sediments may decrease due to the reduced contact
between the active cover material and sediments.
The effectiveness of synthetic liners is based on proper placement,
adequate bonding of adjacent strips of liner, durability of the synthetic
material, and provisions for venting gases that build up under the cover.
The material must be placed on relatively flat areas that are free of jagged
outcroppings and obstructions to prevent tearing. The liners need to be
weighted (preferably with natural sediments) to prevent displacement and
minimize tearing. This will also aid recolonization of the area. Adjacent
strips of liner must be bonded well to provide a continuous cover for the
contaminated sediments.
Implementation
Several methods are available for delivering cover materials to the sea
bottom. A barge-mounted roller apparatus has been proposed for laying
synthetic liners at depths of 25-30 ft, but has not been tested. For inert
and active cover materials, delivery can be accomplished by point-dumping,
pump-down, submerged diffuser, or spray/spreader systems. Point-dumping
involves barges or other vessels that release the cover materials from the
water surface, allowing them to settle over the contaminated sediments.
Such vessels have been extensively used for ocean disposal of dredged spoils
deposited in protected coastal waters. The major drawback of this system is
the high turbidity and possible dispersion as the material moves down
through the water column. Also, silts and clays with low moisture content
tend to fall in a clump, causing resuspension of contaminated sediments when
they impact the bottom. Although sand is less cohesive and has a higher
moisture content, a significant amount of turbidity and resuspension
occurs.
Pump-down systems involve a barge loaded with the cover material and a
telescoping tremie tube or similar means of conveying the material directly
to the sea bottom. Since the material does not pass through the entire
water column, turbidity and dispersion are not as significant a problem as
B-13
-------
with point dumping. Resuspension of contaminated sediments is also lessened
as long as the discharge pipe is maintained close to the bottom. Pump-down
systems are slower at covering a given area than are point-dumping systems
and may require monitoring to ensure complete coverage of the contaminated
sediments.
A submerged diffuser system can also be used to convey the cover
material directly to the bottom and is very effective at controlling the
material placement. The diffuser head reduces the velocity and turbulence
during the material discharge, thereby reducing scour and turbidity.
Thickness of the cover and impact velocity of the material can be controlled
by varying the discharge velocity and height above the bottom. Sediments at
depths of 100 ft can be covered with a submerged diffuser head.
Another system being tested is a spray or spreader system, which is
similar to the pump-down system. A slurry with 15-20 percent solids of the
desired cover material is pumped through a spreader pipe. The spreader pipe
is not necessarily kept near the sediment surface, but the use of a slurry
helps reduce turbidity.
Contaminated sediments can be removed and held on a barge while deeper
uncontaminated sediments are removed. The contaminated sediments are then
replaced in the excavated depression and capped with the cleaner dredged
material. This method has several advantages. A separate disposal site is
not required. The depression created by the deep excavation of uncon-
taminated sediment creates a confined disposal site with edges to contain
the contaminated sediments when they are deposited which will reduce or
eliminate lateral surges during bottom impact. The uncontaminated sediments
used as capping material are generally similar in character to the sur-
rounding sediments, creating a favorable habitat for recolonization of
organisms. This alternative has been proposed for evaluation for the new
Bedford Harbor Superfund site Feasibility Study. A modification of the
overdredging concept has been proposed as an alternative for the removal of
contaminated sediments at the U.S. Navy's Homeport Facility to be construct-
ed at Everett Harbor, WA. Contaminated sediments would be dredged to the
extent of their depth. Deeper dredging would continue into underlying,
clean sediments. The clean and contaminated sediments could then be mixed
resulting in a decreased concentration of contaminates per unit volume of
material. The contaminated sediments would then be disposed of at an open
water site and capped with additional clean material (U.S. Army Corps of
Engineers 1986). Overdredging was used for removing contaminated sediments
at a dredging project site in Budd Inlet, Olympia, WA.
Examples of Capping at Other Sites
Covering contaminated sediments has been considered or implemented at a
number of sites. At the Kepone contamination site in the James River,
covering some contaminated areas with an impervious blanket was considered
but later rejected in favor of several dredging options. For the Mill River
site with high lead concentrations in sediments, isolating the contamination
with a clay or synthetic cap was evaluated as a remedial alternative. It
was concluded that both short- and long-term environmental impacts would be
B-14
-------
moderate from the resuspension of sediment during the capping operation and
later from erosion of the cap, with possible release of the contaminated
sediments. Because of the river flow, there was also concern about anchor-
ing a synthetic cap. Dredging was identified as the preferred alternative,
despite estimated costs doubling those of the capping alternative. An
impermeable liner was considered for PCB-contaminated sediments in the upper
Hudson River, but was eliminated during initial screening because capping
had not been demonstrated 'as feasible for rivers. Capping and covering were
considered for the PCB contamination in Waukegan Harbor. An impermeable
membrane seal was rejected because it was still in the conceptual stage and
would have had a limited lifetime. Use of a clay cap was evaluated in
combination with dredged material containment. A cofferdam would be
constructed to contain contaminated sediments dredged from the upper
harbor. After dewatering, the containment area would be capped with 3 ft of
clay and 5 ft of fill. While not an in situ cap, this option was among
those recommended for the site.
Capping was selected and implemented to control Stamford Harbor
sediments contaminated with metals that were dredged from the harbor and
disposed of in the Central Long Island Sound Disposal Area. Capping the
material reduced impacts on the water column and benthic fauna. Two
materials comparing the effectiveness and durability of sand versus silt
caps were used to cap two disposal areas. Point dumping was used to deliver
both cover materials. The silt material did not spread too extensively
beyond the contaminated dredge spoils because of its cohesiveness. The sand
material was less cohesive and tended to flow upon impact with the bottom.
Both capping operations were judged successful, and subsequent efforts
focused on evaluating the stability of the caps. Recolonization proceeded
faster on the silt cap. A survey 5 mo after completing the covering
operation indicated that over 2 m of the silt cap was lost, although no
contaminated sediments were exposed. Hurricane storm waves and the rough-
ness of the silt cap may have been responsible for the eroded cap. The
nearby sand cap showed no evidence of material loss. It was concluded that
capping operations with silt should include smoothing the final cap surface
to improve erosion resistance. While more long-term monitoring is required,
the operation involving the Stamford Harbor sediments demonstrates that
capping is a viable alternative.
A capping demonstration project was conducted by the Army Corps of
Engineers on the Duwamish Waterway in the Seattle District. Contaminated
sediments were deposited at a 70 ft depth in an existing depression. The
contaminated sediments were then covered with clean, sandy fill material.
The contaminated sediments were removed using a conventional clamshell
dredge. The sediments were carefully placed in a split-hull bottom dumping
barge. The sediments were not allowed to free-fall from the clamshell
bucket into the barge minimizing resuspension of contaminated sediments
during dredging operations. The contaminated sediments were transported to
the existing depression and carefully deposited. The barge was positioned
using direction from personnel onshore with electrical optical distance
measuring equipment and theodolites (Sumeri 1984). The barge hull was
opened and the sediments were deposited rapidly (within 19 sec) as a
cohesive mass. The contaminated sediments were capped the following day
B-15
-------
with clean sands "sprinkled" over the disposal area. "Sprinkling" was
accomplished by slowly opening the barge hull in small increments (Truitt
1986).

Section 121(d) of CERCLA, as amended by SARA, designates RCRA as an
ARAR for evaluating onsite remedial actions. In addition for any offsite
storage, destruction treatment, or secure disposition of hazardous sub-
stances, U.S. EPA cannot provide any remedial actions pursuant to Section
104 of CERCLA unless U.S. EPA enters into a cooperative agreement on
contract with the state in which the release occurred. This would provide,
among other assurances, that the state will ensure the availability of a
hazardous waste disposal facility in compliance with the requirements of
Subtitle C of the Solid Waste Disposal Act, 42 U.S.C. 6921 et sea. The
primary requirements of RCRA that may not apply as ARARS to remedial
alternatives at the Commencement Bay site are:
Part B Permit: The application must contain information on
the site such as planned activities and site conditions that
may influence the transport and fate of contaminants. The
applicant is required to characterize the groundwater regime
and geology underlying the site.
Closure and Post-Closure Performance Standards (40 CFR
264.110-264.120, 265.110-265.120): Establish standards for
soil cleanup/removal, and specifications for containment
structures and caps for landfills. Specifications are
provided for post-closure site maintenance and include
monitoring, reporting, and maintenance of waste containment
systems. Other requirements include notification of the
local land use authority of the presence of contamination and
the locations of waste facilities. All property deeds must
identify the previous use of the site and restrictions on the
future use of the site.
C-l
-------
Groundwater Protection Standards (40 CFR 264.90-264.101,
265.90-265.94): Specify procedures for determining hazardous
constituents and maximum concentration limits (MCLs) for
metals and pesticides and establishes procedures for deter-
mining alternative concentration limits. A program of
groundwater monitoring must be implemented to detect the
presence of contaminants at the point of compliance, which is
usually at site boundaries. If concentrations of particular
compounds are detected above designated limits, more extensive
monitoring is necessary and corrective actions may be
required.
Design requirements for landfills (40 CFR 264.300-264.339,
265.300-265.319): Primarily specify design requirements
(e.g., materials, foundation, placement, capacity, operating
practices) for liners and leachate collection on treatment
systems. For example, a final cover must minimize the
migration of liquids through the landfill, require minimal
maintenance, promote drainage and minimize degradation of the
surface, accommodate settling and subsidence without the loss
of effectiveness, and have a permeability less than the
underlying materials.
Use and management of containers, tanks, surface impoundments,
and waste piles (40 CFR 264.170-264.269; 265.170-265.269):
Specify requirements for waste analysis and trial tests
(interim status facilities); inspections; containment;
monitoring; design and operation; emergency repairs; incom-
patible, ignitable, or reactive wastes; and closure and post-
closure care. For surface impoundments, waste liquids and
residues must be removed and appropriately managed and free
liquids must be eliminated. Wastes remaining at the site are
subject to requirements similar to those for landfills.
Land Treatment (40 CFR 264.270-264.299; 265.270-265.299):
Provide requirements for waste analysis (for interim status
facilities), development and demonstration of a treatment
program, design and operation, monitoring, closure and post-
closure, and cultivation of food chain crops.
Incinerators (40 CFR 264.340-264.999; 265.340-265.999):
Provide requirements for waste analysis, performance stand-
ards, hazardous waste incinerator permits, operation proce-
dures, and monitoring. For example, these sections require
chemical analysis of wastes to be burned, performance of
trial burns, 99.99 percent burn efficiency for principal
organic hazardous constituents, air emissions monitoring,
hydrogen chloride control to 99 percent removal or 1.8 kg/h,
maximum particulate emissions of 180 mg/m3, removal of all
waste and waste residues upon closure, and submittal of a
Part B permit application.
C-2
-------
Table C-l lists several RCRA guidance documents published by U.S. EPA
as part of its solid waste program. These documents are not promulgated, and
they do not have the status of potential ARARs; however, they may be
considered for designing and implementing remedial alternatives and
determining cleanup levels that are protective of the environment and human
health.
Toxic Substances Control Act (TSCA. 15 U.S.C. 2601 et sea.)
TSCA provides for U.S. EPA to regulate the testing, manufacture,
processing, and distribution of toxic chemicals. Title 40 CFR Parts 761.60-
761.79 provide requirements for maintaining records, reporting activities,
storage, handling, incineration, and landfilling of PCB-containing wastes.
TSCA is most applicable to the Commencement Bay site in terms of its
provisions for the control of PCB-containing material. TSCA also contains
provisions for managing material containing dioxin; however, dioxin has not
been documented as a contaminant of concern in Commencement Bay. Some
dredged material may be subject to material testing, handling, and disposal
requirements of TSCA. In addition, TSCA health data and data generated from
TSCA advisories may be relevant and appropriate to remedial action design
and implementation. TSCA requirements provide that:
Incineration must destroy 99.99 percent of PCBs and the
incinerator must be approved and operated under specific
conditions
Materials with PCB concentrations equal to or greater than
50 ppm must be disposed of in an approved chemical waste
landfill
Materials with less than 50 ppm PCBs may be disposed of in a
sanitary landfill
The following requirements are specific to chemical waste
landfills:
A synthetic liner may be required to contain hazardous
materials
The landfill must be located in impermeable formations
and away from floodplains, shorelands, and groundwater
recharge areas
The landfill must be located in areas of low to high
relief to minimize erosion
Groundwater and surface water at the landfill must be
monitored for at least PCBs, chlorinated organics,
specific conductance, and pH
A leachate collection and monitoring system must be
installed and maintained

Clean Water Act (CWA. 42 U.S.C. 1251 et sea. (Federal Water Pollution
Control Act)
The CWA is applicable to at least two categories of remedial alterna-
tives at the Commencement Bay site:
Dredging and dredged material disposal
Point source discharge controls.
Section 404 of the CWA provides guidelines and requirements for dredging
and dredged material management, including the designation of disposal
sites. Section 404 requirements may be applicable to all dredging and
dredged material disposal remedial alternatives. Section 402 of the CWA
establishes the National Pollutant Discharge Evaluation System (NPDES) for
issuing permits to point source discharges. Requirements under Section 402
may be applicable to alternatives that involve the issuance or modification
of existing NPDES permits. The following sections present descriptions of
pertinent guidelines and requirements of CWA.
Federal Guidelines for Specifying Disposal Sites--
Federal disposal site guidelines describe an evaluation process for
permits (e.g., general permits) for a category of activities if the activi-
ties have similar impacts and their separate and cumulative environmental
impacts are minimal. The following guidelines would be applicable under the
CWA to any designated (open-water) disposal site:
Criteria for Compliance with GuidelinesThere are four categories of
restrictions on discharges of dredged material. In summary, no discharge of
dredged or fill material shall be permitted if:
1. There is a practicable alternative to the proposed dis-
charge.
2. After consideration of dilution and dispersion, the action
contributes to a violation of a state water quality standard,
toxic effluent standard, or toxic effluent prohibition;
threatens the existence of an endangered species; or threatens
a marine sanctuary.
3. The discharge will cause or contribute to significant adverse
effects on human health, or cause or contribute to significant
degradation of the waters of the U.S.
C-7
-------
4. All appropriate and practicable steps have not been taken to
minimize potential adverse effects to the aquatic environment.
The guidelines also require several kinds of effects determinations
(e.g., for physical substrates and physical and chemical characteristics of
water and biota) and require consideration of several potential environ-
mental impacts (e.g., impacts to physical and chemical water characteristics,
aquatic biota and other wildlife, wetlands, recreational and commercial
fisheries, water-related recreation, and aesthetics).
Evaluation and Testing of Dredged Material--The guidelines state that
material shall be examined for the potential presence of contaminants based
on potential sources and routes of contamination from adjacent contaminated
material; upland sites; spills; industrial, municipal, or other point
sources; or natural mineral deposits. Testing is described for chemical-
biological interactive effects, water column effects, and effects on benthos.
Actions to Minimize Adverse EffectsThese guidelines describe actions
concerning discharge location; actual discharge of the material; control of
the material after discharge; methods of dispersion; available technology;
the effect of actions on plant and animal populations, and human use; and
other actions.
Federal Guidelines for Permitting Discharges of Dredged Material--
Guidelines for issuing permits for discharges of dredged or fill
material are specified in Parts 320 to 330 of Title 33 of the Code of
Federal Regulations, dated 13 November 1986 [Regulatory Program for the
Corps of Engineers 1986]. All dredged material discharge permits (also
known as 404 permits) are processed by the U.S. Army Corps of Engineers.
However, under Section 404(c) of the CWA, and U.S. EPA's regulations
codified at 40 CFR Part 231, the Administrator of U.S. EPA can prohibit or
withdraw a permit upon determination that the discharge would have unaccep-
table adverse effects.
State Water Quality Certification--
Under Section 301 of the Clean Water Act, a state water quality
certification is necessary for any project (e.g., dredging and dredged
material disposal) that may cause the violation of a state water quality
standard. For the Commencement Bay site, this certification would be
granted or denied by Ecology. Chapter 173-201 of the Washington Adminis-
trative Code (WAC) details water quality standards for waters of the state.
NPDES Discharge Permits--
Regulations codified at 40 CFR Part 122 establish a program and
guidelines for issuing permits for point-source discharges. Limits on the
discharge (concentrations and/or value) of contaminants are set on a case-
by-case basis. The Washington Department of Ecology currently administers
discharge permits in the Commencement Bay site. Effluent limitations and
standards for toxic pollutant effluent promulgated pursuant to Sections 301,
C-8
-------
302, 303, 306, 307, and 403 of the CWA are codified at Title 40 CFR Part
129. Several remedial alternatives involve modification of the terms and
conditions of NPDES permits.
U.S. EPA's Office of Water administers the Clean Water Act and has
published the following guidance documents that may be considered in the
evaluation of Commencement Bay remedial activities:
304(g) Guidance Document Revised Pretreatment Guidelines
(3 volumes)
Water Quality Guidance Documents
Ecological Evaluation of Proposed Discharge of Dredged
Material into Ocean Waters (1977)
Technical Support Manual: Waterbody Surveys and
Assessments for Conducting Use Attainability Analyses
(1983)
Water-Related Environmental Fate of 129 Priority
Pollutants (1979)
Water Quality Standards Handbook (1983)
Technical Support Document for Water Quality-Based Toxics
Control
NPDES Best Management Practices Guidance Manual (June
1981)
Case studies on toxicity reduction evaluation for the
NPDES program (May 1983)
Laboratory protocols developed pursuant to Clean Water Act
Section 30l(h).
Federal Water Quality Criteria (1976. 1980. 1984)
Federal water quality criteria are not legally enforceable. However,
state water quality standards are legally enforceable, and are based on
federal water quality criteria. When neither state standards nor MCLs exist
for a given pollutant, federal water quality criteria are applicable. Water
quality criteria may be applicable to all remedial activities affecting
water quality (e.g., point source and nonpoint source discharges, and
dredging).
Rivers and Harbors Appropriation Act (33 U.S.C. 401 et seq.)
The Rivers and Harbors Appropriation Act requires a permit from the U.S.
Army Corps of Engineers for construction, dredging, and filling below the
mean high-water line. Implementation of remedial actions involving such
C-9
-------
activities may require consideration of the substantive requirements of the
permit process that is now incorporated into Section 404 of CWA.
National Environmental Policy Act (NEPA 43 U.S.C. 1701-1782)
In general, NEPA requires the preparation of an Environmental Impact
Statement (EIS) for any major federal actions significantly affecting the
quality of the human environment. The requirements of NEPA are waived if
the functional equivalent of an EIS is achieved under another federal law,
such as CERCLA.
Safe Drinking Water Act (42 U.S.C. 300 et sea., as amended)
The Safe Drinking Water Act primarily establishes requirements and
guidelines for contaminant levels in drinking water and underground injection
control. Based on literature reviewed, there appears to be no groundwater
aquifers in the study area that would require implementation of requirements
under this act. However, certain guidance provided by the Act (e.g., recom-
mended MCL) is applicable for use in implementing remedies for groundwater
cleanup. Although not a part of the Safe Drinking Water Act, U.S. EPA's
Groundwater Protection Strategy is relevant and appropriate for use as
additional guidance for remedial actions.
The following guidance documents are available from U.S. EPA and may be
appropriate for defining and evaluating remedial activities for groundwater:
Elements of aquifer identification
Interim guidance for public participation
Definition of major facilities
Corrective action requirements
Requirements applicable to wells injecting into, through, or
above an aquifer which has been exempted pursuant to Section
146.104(b)(4)
Guidance for underground injection control implementation on
Indian lands.
Clean Air Act (42 U.S.C. 7401 et sea.)
The Clean Air Act establishes National Ambient Air Quality Standards,
however where more stringent, these standards are superceded by state
standards. Standards under the Clean Air Act may be applicable to contami-
nated material exposed to air (e.g., dredged material) and to treatment
strategies such as air strippers and incinerators. The Clean Air Act may
provide additional guidance for cleanup through documentation of the public
health basis for listing pollutants as hazardous under (Section 112 of the
Act). The Clean Air Act establishes several requirements, including:
C-10
-------
National Ambient Air Quality Standards for Total Suspended
Particulates (40 CFR Parts 50.6 and 50.7) and Ozone (40 CFR
Part 50.9)
National Emissions Standards for Hazardous Air Pollutants for
Asbestos (40 CFR Part 61.140-61.156) and Radionuclides (40 CFR
Part 61 and 10 CFR Parts 20.101-20.108).
Rules for the Transportation of Hazardous Materials
Federal regulations codified at Title 49 CFR Part 107, 171.1-171.50,
apply to the transport of hazardous materials on federal highways, and are
applicable to the offsite transport of contaminated material (e.g., dredged
material) from the Commencement Bay site.
Occupational Safety and Health Act (QSHA. 29 U.S.C. 651 et sea.)
OSHA establishes safety requirements (e.g., maximum permissible exposure
limits) for workers in the workplace. OSHA regulations may be applicable to
workers involved in any site remediation activities that involve potential
worker contact with a hazardous substance. In addition, OSHA requirements
may be applicable to the potentially exposed public. OSHA requirements
include:
Occupational Safety and Health Standards (General Industry
Standards, Title 29 CFR Part 1910)
Safety and Health Standards for Federal Service Contracts
(Title 29 CFR Part 1926)
Shipyards and Longshore Standards (Title 29 CFR Parts 1915
and 1918)
Recordkeeping, reporting and related regulations (Title 29 CFR
Part 1904).
Coastal Zone Management Act of 1972 (CZMA. 16 U.S.C. 1451 et sea.)
The CZMA establishes a framework for states to develop and implement a
Coastal Zone Management Program. Under the CZMA, local governments prepare
land-use plans for their coastal zones. In the Commencement Bay area,
Tacoma's Shoreline Master Program (SMP) supercedes the CZMA. The federal
CZMA would, therefore, not be directly applicable to remedial alternatives.
OTHER FEDERAL LAWS AND REGULATIONS
The following list of federal laws and regulations may be important at
some remedial action locations, but were determined to probably not affect
the implementation of remedial alternatives at the Commencement Bay site:
C-ll
-------
Historic Sites, Buildings, and Antiquities Act (16 U.S.C.
461 et seq.); It is not anticipated that any historic sites,
buildings, or antiquities will be affected by. remedial
alternatives.
National Historic Preservation Act (16 U.S.C. 470, et sea..
Titles 7 CFR Part 650, 32 CFR Part 229, and 43 CFR Part 7):
Based on materials reviewed, there do not appear to be any
historic sites that would be affected by remedial alterna-
tives.
Endangered Species Act of 1973 (16 U.S.C. 1531, et seq..Title
50 CFR Parts 81, 225, and 402): Based on the literature
reviewed, it is not anticipated that any endangered species
will be adversely affected by remedial alternatives at the
site.
Fish and Wildlife Coordination Act (16 U.S.C. 661 et seq.);
CERCLA actions at the site probably are the functional
equivalent of requirements under this act.
Fish and Wildlife Improvement Act of 1978 and Fish and
Wildlife Act of 1956 (16 U.S.C. 742 et sea,.): CERCLA actions
at the site probably are the functional equivalent of require-
ments under this act.
Fish and Wildlife Conservation Act of 1980 (16 U.S.C. 2901,
et seq.. Title 50 CFR Part 83): CERCLA actions at the site
probably are the functional equivalent of requirements under
this act.
Intergovernmental Review of Federal Programs (Title 40 CFR
Part 29): CERCLA actions at the site probably are the func-
tional equivalent of requirements under this act.
Uniform Relocation Assistance and Real Property Acquisition
Act of 1979 (Title 30 CFR Part 4): It is not anticipated that
remedial activities will involve the relocation of residents.
Floodplain Management (Executive Order 11988, 24 May 1977):
Based on the material reviewed, the Commencement Bay site does
not fall within the jurisdiction of this law.
Protection of Wetlands (Executive Order 11990, 24 May 1977):
There are no protected wetlands at the Commencement Bay site.
STATE LAWS AND REGULATIONS
The State of Washington has developed its own hazardous waste regula-
tions that are similar, and in some cases, more restrictive than the federal
regulations. The following sections highlight relevant state laws and
regulations.
C-12
-------
Designation of Dangerous Wastes (WAC 173-303-070 to 103)
State hazardous waste regulations establish procedures for defining
hazardous waste as either Dangerous Waste (DW) or Extremely Hazardous Waste
(EHW). Residues, contaminated soils, water, or other debris from the
cleanup of compound spills listed on the "moderately dangerous chemical
products list" (WAC 173-303-9903) in excess of 400 Ib are designated as DW.
If the spilled compounds are listed on the "acutely dangerous chemical
products list" (WAC 173-303-9903), soils, residues, water, or other debris
in excess of 220 Ib are considered EHW. Additional distinction is based on
persistence, concentration, carcinogenicity, mutagenicity, teratogenicity,
concentration of certain compounds, and toxicity. Wastes which were not
designated as hazardous waste at the time of disposal are not considered DW
or EHW. The definition of contaminated material pursuant to these regula-
tions may be applicable to how the materials are handled and disposed of.
It is not expected that any dredged material removed from Commencement Bay
problem areas will classify as EHW.
Disposal of Extremely Hazardous Waste (WAC 173-303-140)
Extremely hazardous waste must be disposed of at a facility designated
by Ecology. Such a facility has not yet been designated; however, when
designated it must satisfy landfill requirements of WAC 173-303-665 (these
requirements are comparable to the corresponding federal regulations).
Surface Impoundments (WAC 173-303-650)
These regulations are comparable to federal regulations for surface
impoundments (e.g., 40 CFR 264.110-264.120, 265.110-265.120, 264.300-
264.339, and 265.300-265.319) with the additional requirement that no EHW
may be left in place upon closure of the facility. State regulations for
surface may be applicable for remedial activities involving landfill ing or
storage of contaminated material.
Incinerators (WAC 173-303-670)
In addition to requirements specified by federal regulations (40 CFR
264.340-264.999 and 265.340-265.999), state regulations require compliance
with the emission standards of the Puget Sound Air Pollution Control Agency
(PSAPCA). PSAPCA limits air emissions to 0.01 grains of suspended particu-
late per standard dry cubic foot of air (compared to a 0.08 limit in federal
regulations) and requires the use of best available control technology. In
addition, because Tacoma is a "non-attainment" area for particulates,
emissions of particulates must be kept below 50 Ib/h.
Groundwater Protection for Waste Management Facilities
In addition to requirements specified in federal regulations (e.g., 40
CFR 264.90-264.101 and 265.90-265.94), Ecology determines on a case-by-case
basis the point at which compliance must be met, determines dangerous
constituents which are monitored, and determines compliance concentrations.
C-13
-------
Groundwater regulations may be applicable to any landfills or impoundments
used for disposal of contaminated material.
Water Quality Standards for Waters of the State of Washington (WAC 173-201)
Ecology classifies surface waters according to their water quality and
uses of the water body. The surface waters at the Commencement Bay site are
currently classified as follows:
Class B (good) - Puyallup River, Inner Commencement Bay
Class C (fair) - Commencement Bay - City Waterway.
WAC 173-201 establishes criteria (for each water classification) for fecal
coliform bacteria, dissolved oxygen, total dissolved gas, temperature, pH,
and turbidity. WAC 173-201 further states that concentrations of contami-
nants must be below levels which may adversely affect human health, the
environment, or uses of the water body. The criteria and classifications of
the state water quality standards do not apply within defined dilution zones
near point sources; however, WAC 173-201 states that within the dilution
zone, fish and shellfish must not be killed or aesthetic values diminished.
State water quality standards are applicable requirements and any new
discharge or activity affecting water quality (e.g., dredging or aquatic
disposal of dredged material) and discharge permits may need to comply with
them. This requirement may affect implementation of all Clean Water Act
related activities.
Water Pollution Control. Pollution Disclosure Act and Water Resources Act
(90.48. 90.52. and 90.54 RCW)
These laws provide that surface waters and groundwater of the state are
to be protected to maximize beneficial uses. Materials and substances that
might enter these waters must receive prior treatment with known, available,
and reasonable methods. Pollution control and discharge regulations are
applicable for all dischargers in the Commencement Bay area.
Protection of Upper Aquifer Zones (WAC 173-154)
WAC 173-154 provides for the protection (to the extent practicable) of
upper aquifers and upper aquifer zones to avoid depletions, excessive water-
level declines, or reductions in water quality. State regulations for upper
aquifer zones are applicable to remedial alternatives that involve treating
groundwater or presenting risks of groundwater contamination.
State Water Code (90.03 RCW) and Water Rights (90.14 RCW)
Water code and water rights laws specify conditions for extracting
surface water or groundwater for nondomestic uses. In essence, the laws
provide that water extraction must be consistent with beneficial uses of the
resources and must not be wasteful. Water code and water rights regulations
pertain to aquifers from which water is extracted for use. Because there is
C-14
-------
no current use of aquifers underlying the Commencement Bay site (based on
the literature reviewed), these regulations are probably not applicable.
Water Well Construction and Withdrawal Regulations (90.44.130 RCW and WAC
173-160)
Well construction regulations establish minimum standards for water well
construction and require the preparation of construction reports. Water well
regulations may be applicable for alternatives involving well construction
for groundwater extraction and treatment.
Submissions of Plans and Reports for Construction of Wastewater Facilities
(WAC 173-240)
WAC 173-240 regulations require that Ecology review and approve plans
for wastewater treatment facilities. These regulations may be applicable if
new treatment facilities are built for remediation purposes.
Air Quality. General Emission Standards fWAC 173-400-040(5)1
Air quality regulations require that contaminant air emissions from any
source not be detrimental to the health, safety, or welfare of any person and
must not damage any property or business. General emission regulations may
be applicable to remedial actions that involve the release of contaminants
to the air (e.g., air strippers, incinerators, land storage of contaminated
material).
Washington Clean Air Act. Implementation of Regulations for Air Containment
Sources, and General Regulations for Air Pollution Sources (RCW 70.94. WAC
173-400 and 173-403)
Additional regulations require a review process for new sources of air
emission. During the review process, the contaminants are identified, the
best available control technology is determined, the maximum ambient air
concentration is estimated, and an acceptable ambient level is established.
Additional air regulations may be applicable to new sources that are part of
a remedial activity affecting air quality.
Shoreline Management Act of 1971 (SMA)
The SMA is analogous to the federal CZMA in that it provides for the
preparation of SMPs by counties and cities for the regulation of land use in
the coastal zone. The Tacoma SMP generally supersedes the SMA. The SMA may
be applicable to certain activities along the shoreline (e.g., dredging or
construction of remediation facilities) that are subject to review at the
state level by the Shoreline Hearings Board. Pursuant to the SMA, all
construction valued at more than $2,500 in the shoreline area (generally, at
least 200 ft shoreward of "ordinary high water") requires a Shoreline
Substantial Development Permit. The substantive requirements of the Tacoma
SMP and the state SMA must be considered for remedial activities in the
shoreline area (e.g., aquatic, nearshore, and upland disposal of dredged
material; and placement or treatment of wastes).

Minimum Functional Standards for Solid Waste Handling (WAC 173-304)
WAC 173-304 regulations pertain to solid waste handling facilities
(e.g., municipal landfills. They contain provisions for facility design,
maintenance, and closure.
Permits to Discharge Commercial Industrial Wastes (WAC 173-216)
WAC 173-216 regulations establish a permit system for discharges of
wastewater to groundwater. Solid waste handling regulations may be appli-
cable to remedial activities that involve municipal landfills. The following
regulations establish a permit system for discharges of wastewater to
groundwater and may be applicable for certain remedial activities:
Underground Injection Control: These regulations pertain to
the injection of wastes into aquifers which are used for
drinking water. Based on the literature reviewed, aquifers
underlying the Commencement Bay site are not used for
drinking water.
Protection of Withdrawal Facilities Associated with Ground-
water Rights: These regulations pertain to withdrawal
facilities operating in areas where there is a source of
water for an existing water right.
Protection of Upper Aquifer Zones: These regulations govern
aquifer systems where an upper aquifer can interact with lower
ones or with surface waters.
Underground In.iection Control Program (WAC 173-218)
WAC 173-218 regulations pertain to the injection of wastes into aquifers
that are used for drinking water.
Protection of Withdrawal Facilities Associated with Groundwater Rights (WAC
173-150)
WAC 173-150 regulations pertain to withdrawal facilities operating in
areas where the source of water has an existing water right.
Protection of Upper Aouifer Zones (WAC 173-154)
WAC 173-154 regulations govern aquifer systems where an upper aquifer
can interact with lower ones or with surface waters.
Water Pollution Control (RCW 90.48)
RCW 90.48 provides for use of water quality regulations at hazardous
waste sites and is generally applicable to the Commencement Bay site.

Washington Department of Ecology Final Cleanup Policy (Tech. Memo. 10 July
1984)
The Final Cleanup Policy statement issued by Ecology in 1984 establishes
the target level of cleanup for state-led remediation sites and is generally
applicable to the.Commencement Bay site. Numerical criteria are not given
in the policy statement.
Requirements for the Transport of Hazardous Materials (WAC 446-50)
WAC 446-50 regulations are generally analogous to the corresponding
federal regulations. Transport regulations are applicable to any offsite
transport of hazardous materials (e.g., to an approved RCRA disposal site).
Hydraulics Permits and Code Rules (RCW 75-20.100. WAC 220-110)
Hydraulics permit regulations require the issuance of a hydraulics
permit by the Washington Departments of Fishery and Game for any project
that may interfere with the natural flow of surface water. Substantive
permit-related requirements may be applicable to onsite actions.
Washington Industrial Safety and Health Act Occupational Health Standards--
Safety Standards for Carcinogens (WAC 296-62)
State safety and health regulations are generally similar to those
espoused by the federal regulations (i.e., OSHA) and are applicable to all
remedial actions involving potential human exposure to hazardous materials.
State Environmental Policy Act
SEPA is analogous to NEPA at the federal level. The law requires
preparation of an EIS for projects with significant environmental impacts.
Based on information to date, functional equivalence of an EIS will most
likely be satisfied by work performed at the Commencement Bay site. In such
cases, preparation of an EIS under SEPA would be unnecessary.
REGIONAL REGULATION
PSAPCA Air Emissions Permits
Air emissions permits are required of all new sources according to
established procedures and criteria (see Washington Clean Air Act and In-
cinerators above). Regional air emission requirements may be applicable to
remedial activities involving exposure of contaminants to air (e.g., in-
cinerators, air strippers, exposure of dredged material). Although air
emissions permits would be required only for all new offsite sources, onsite
facilities may be required to meet relevant and appropriate permit condi-
tions.

TRIBAL REGULATIONS
Although Puyallup tribal lands do not include portions of the Commence-
ment Bay Superfund site, the tribes have significant jurisdiction over
traditional fishing grounds which may include segments of the site where
remedial activities are planned. These and other environmental concerns of
the tribes will be addressed during final design of a remedial alternative,
including replacement of intertidal sediments dredged during remediation.
TBC REGIONAL AND LOCAL ORDINANCES AND REGULATIONS
Puget Sound Dredged Disposal Analysis (PSDDA) Guidelines
PSDDA is an interagency study undertaken to provide the basis for
developing publicly acceptable guidelines for the environmentally safe
unconfined, open-water disposal of dredged material. PSDDA has recommended
guidelines for the biological and chemical evaluation of sediments and has
developed interim criteria for the open-water disposal at disposal sites in
Port Gardner and Elliott Bay. Although these guidelines and criteria are
not yet promulgated (and are therefore not considered ARARs), they are
probably relevant and appropriate for application to open-water disposal
alternatives in Commencement Bay. Table C-2 presents biological and
chemical disposal guidelines for alternative allowable site conditions,
and Table C-3 presents screening levels and maximum levels for chemical
constituents in sediments. The values in Table C-3 may be revised following
the PSDDA annual review scheduled for February 1988 (Vrabek, F., 20 December
1988, personal communication). The values would presumably be revised to
reflect new AET values (PTI 1988).
Tacoma-Pierce County Health Department Regulations for Sanitary Landfills
The Tacoma-Pierce County Health Department has adopted state solid waste
management regulations for sanitary landfills. As of September 1987, the
department was in the process of revising the regulations to better meet
their needs.
In general, ordinances and requirements of the City of Tacoma relate to
land-use controls. The applicability of land-use ordinances and requirements
may vary among sites and will depend on the nature of each remedial activity;
therefore, local ordinances will be addressed in the final FS, Applicable
ordinances and regulations of the City of Tacoma include:
Tacoma Shoreline Substantial Development Permit
Tacoma land use approval
Tacoma building permit requirements
Tacoma grading and drainage ordinances
Discharge permit for City of Tacoma sanitary sewer.

TABLE C-3. (Continued)
The following procedures were used to develop SL, ML1, ML2, and MLS:
SL = 10% of ML2 or reference area concentration, whichever is higher
but no greater than the lowest AET for a range of biological
indicators.
ML1 = Lowest Apparent Effects Threshold Value (LAET) for a range of
biological indicators.
ML2 = Highest Apparent Effects Threshold Value (HAET) for a range of
biological indicators.
ML3 = (ML2) x (2).
a The ML set for this chemical is based on a biological indicator with a
definitive AET. PSDDA is considering adjusting these values upward based on
another biological indicator currently represented by a "greater than" value
for the AET (Seller et al. 1986). For such biological indicators, the
"greater than" value is the highest concentration of a chemical above which
there has yet to be a bioassay that met disposal guidelines, and indicates
that there were no impacted stations with chemical concentrations above this
value (a requirement for setting definitive AET). During review by PSDDA of
actual testing data, it was determined that these "greater than" values are
useful estimates of the maximum level until more definitive data are
available.
b No ML was originally set for these chemicals because definitive AET could
not be set for any biological indicator (see discussion on "greater than"
values in footnote a). PSDDA is considering assigning ML values for several
of these chemicals based on the highest "greater than" value (Seller et al.
1986).
c For these compounds, the reference concentration was higher than the
calculated value of SL so SL was set at the reference value.
d PSDDA agreed that biological testing should not be triggered solely by the
presence of phthalates. Because these compounds are often present as
laboratory contaminants, the highest AET was used as the screening level and
no maximum levels were set.
e For chemicals with ML2 values set by the Equilibrium Partitioning approach,
ML1 was set equal to ML2, and SL and MLS values were calculated from ML2
according to the formulas given above.
f These ML2 values were set using the Equilibrium Partitioning approach
because no AET values were available.
9 SL for these pesticides was set to 5 times an assumed analytical detection
limit of 1 ug/kg dry weight sediment. No sediment quality values were
available for setting maximum levels.

Tacoma Shoreline Substantial Development Permit
All projects of at least $2,500 in value in the shoreline area within
Tacoma City limits require a Shoreline Substantial Development Permit. In
general, a permit is issued for projects that meet specifications and
requirements (e.g., height and use restrictions) of their particular
shoreline designations. All shoreline segments in the vicinity of the
Commencement Bay Superfund are designated as urban. Categories of use
activities in these areas include:
Port and water-related industry Breakwaters
Bulkheads Jetties and groins
Piers Landfill ing
Dredging
Permitted activities vary by shoreline segment and may be only conditionally
permitted or not allowed in some segments (e.g., dredging in the Puyallup
River).
Tacoma Land Use Approval
Remedial alternatives that involve new land-use activities must consider
Tacoma land-use ordinances such as height restrictions and zoning require-
ments. These restrictions may vary on a site-specific basis.
Tacoma Building Code
Remedial alternatives that involve new construction and/or demolition
must consider a wide range of building code requirements, including storm-
water management (e.g., retention or treatment) and erosion control.
Tacoma Grading and Drainage Ordinances
Remedial alternatives that involve new construction and/or demolition
may be subject to requirements pursuant to grading and drainage permits
issued by the City of Tacoma.
Discharge Permit for City of Tacoma Sanitary Sewers
Remedial alternatives that involve a discharge to the Tacoma sanitary
sewer system may be subject to city pretreatment and permitting requirements.

APPENDIX D
METHOD FOR ESTIMATING COSTS OF SEDIMENT REMEDIAL ALTERNATIVES
COMMENCEMENT BAY NEARSHORE/TIDEFLATS FEASIBILITY STUDY
Detailed cost estimates were prepared for each applicable sediment
remedial alternative developed for each of the nine Commencement Bay
Feasibility Study (FS) problem areas. Unit costs used to estimate overall
project costs are described in the following pages. Elements of remediation
are presented in chronological order, from initiation of the sediment
refinement sampling program to disposal and subsequent monitoring. Except
for in situ capping, all unit costs are presented as dollar per cubic yard of
sediment treated or disposed. In situ capping costs are presented as dollar
per square yard of contaminated area. Material and construction costs from
historic sources were adjusted to 1988 values using a 4 percent inflationary
factor.
A unit cost analysis for the chemical and biological sampling, dredge
operation, treatment, disposal, and site operation and maintenance (O&M) is
provided in Table D-l. Chemical analyses required for each problem area and
the corresponding detailed cost breakdowns are presented in Table D-2. Cost
estimates for disposal site acquisition and preparation, facility construc-
tion, disposal operation, and site maintenance and monitoring are found in
Tables D-3 through D-6. Detailed cost breakdowns for waterway-specific
remedial alternatives are shown in Tables D-7 through D-16. All tables
appear at the end of the text.
PRE-REMEDIATION SAMPLING PROGRAM
It was assumed that the estimates of area and volume of sediment
requiring remediation would be refined by a pre-remediation sampling
program following requirements for dredged material disposal assessments
recommended by U.S. Army Corps of Engineers (1988). The core sampling
frequency recommended in this document for sediments with high contaminant
concentrations is one for every 4,000 yd3 for sediments above the 4-ft
depth. The sampling strategies regarding station locations and vertical
profiles are recommended in Appendix A of the Commencement Bay Integrated
Action Plan (PTI 1988a). Estimated sediment core costs, including boat and
crew time, are approximately $1,500 per core for 10 to 50 cores in a
sampling event. Chemical analysis costs will vary with each problem area,
depending on contaminants of concern. In all cases, chemical analysis costs
include an extra 25 percent for quality assurance/quality control (i.e.,
blanks, replicates, and spikes) and other incidental analyses.
DREDGING OF CONTAMINATED SEDIMENTS
Remedial alternatives involving dredging specify hydraulic dredges
with the cutterhead option or mechanical dredges with a clamshell bucket.
Estimated operating costs for a cutterhead with a capacity of the 500 yd3/h,
including the hydraulic transport of dredge slurry for 2 mi by pipeline, are
D-l
-------
$1.50/yd3 (Hillus, L., 4 February 1988, personal communication). The
estimated cost of using an additional pipeline booster to transfer sediments
to an upland disposal site is approximately $0.50/yd3.
The cost of modifying a clamshell bucket to make it watertight was
estimated at $20,000. The estimated operating expenses for a clamshell
dredge with a capacity of 200 yd-Vh are $1.25/yd3. This estimate does not
include the cost of transporting dredge spoils to the disposal site. Barge
transport costs for hauling sediment up to 5 mi were estimated at $0.50/ycP
(Morris, J., 18 November 1987, personal communication). Truck transport
costs for a round trip of 2 mi at 2 loads per hour were estimated at
$2.01/yd3 (R.S. Means 1988).
TREATMENT OF CONTAMINATED DREDGE MATERIALS
The treatment options included among the remedial alternatives are
incineration, solvent extraction, biological land treatment, solidification,
and chemical clarification of dredge water (at nearshore and upland disposal
sites). The low heating value of sediments translates into high thermal
treatment costs. U.S. EPA (1985) estimates that thermal treatment costs
for contaminated soil range from $150 to $500 per ton, depending on the type
of contaminants and heating value of the waste matrix. This estimate
includes site preparation, labor, equipment, utilities, mobilization,
decontamination, and demobilization. For the Commencement Bay Feasibility
Study, unit costs for a mobile rotary kiln incineration unit were assumed to
be $300/yd3, based on a sediment density of 1.35 ton/yd3 and an operating
cost of $220/ton (U.S. EPA 1986). This unit cost does not include mobiliza-
tion and demobilization costs. (As explained below, a 10 percent markup was
applied for mobilization and demobilization for all remedial activities.)
The unit cost for solvent extraction is estimated to range from $90 to
$120/yd3 (Austin, D., 22 January 1988, personal communication).
For the land treatment option, it was assumed that a $100,000 treat-
ability study would be required. Because an extensive evaluation of site
soil and waste characteristics is necessary to determine the assimilative
capacity of the soil for waste constituents, especially metals, it was
assumed that a single 1-ft thick application of dredged sediment would be
made. This is probably a liberal estimate of the amount of sediment to be
applied.
Costs for solidification were estimated to be $25/yd3 of dredged
sediment, assuming use of a cement/pozzolanic material (Conner, J.,
18 November 1987, personal communication).
Water removed from sediments as part of sedimentation was assumed to
require chemical clarification because of the low solids content of the
sediment/water slurry (15-25 percent) and the potential for high suspended
solids concentrations in the effluent. Chemical clarification operating
costs were estimated at $0.35/yd3 of hydraulically dredged sediment
(Schroeder, P., 18 November 1987, personal communication).

DISPOSAL SITE PREPARATION AND FACILITY CONSTRUCTION
For open-water confined aquatic disposal, major cost items include
construction of the underwater dike and construction of the vertical
downpipe and diffuser for placing sediments and capping materials. An
extensive topographical investigation was included in the cost for underwater
dike construction. Diffuser costs were based on data from Phillips et al.
(1985). A disposal charge of $0.12/yd3 ($0.20/ft2) was estimated, based on
the experience from other open-water confined aquatic disposal projects. A
15-ft fill depth and 3-ft cap were also assumed.
The major cost items for nearshore disposal, upland nonhazardous waste
disposal, and upland RCRA facility disposal are associated with site
acquisition, site preparation, dike and berm construction, and installation
of liner and cap materials. Costs for these confinement structure components
depend on fill depths, which were assumed to be 15 ft for upland disposal
and 30 ft for nearshore disposal.
The land values for disposal sites were estimated to be $25,000/ac for
upland locations (Rockey, M., 11 August 1987, personal communication) and
$435,600/ac for nearshore sites (U.S. Army Corps of Engineers 1988). Costs
of constructing the primary settling basin (dike and weir) for upland and
nearshore sites were estimated by averaging costs for all potential sites
presented in the Table 5-4 of Phillips et al. (1985). Clarification unit
construction, including an additional dike and weir, was estimated at about
25 percent of the cost of the primary settling basin (Schroeder 1983).
For nearshore sites accepting untreated sediment a 3-ft thick soil/ben-
tonite cap and no associated liner were assumed. Upland RCRA facilities
accepting untreated sediments were assumed to be lined with 3 ft of clay,
dual synthetic liners, and an underdrain system for leachate collection.
Such facilities were also assumed to be capped with 3 ft of clay, a synthetic
liner, a drainage layer of sand and gravel, and, finally, a topsoil
vegetation layer.
It was assumed that treated sediments would be disposed of in an upland
landfill lined with 4 ft of clay and underdrain system, and capped with 2 ft
of clay. Liner costs for treated sediments were assumed to be less than
those for untreated sediments to reflect the reduced sediment contaminant
concentrations and mobility.
Material and installation costs for synthetic liners and caps were
estimated from data provided by Phillips et al. (1985).
Site capacities were assumed to be 730,000 yd3 (8 ac) for the nearshore
disposal at the Blair Waterway middle slip, and 1,250,000 yd3 (40 ac) each
for open-water confined aquatic disposal at Hylebos/Browns Point and upland
disposal at an unidentified site. The unit costs for disposal facility
construction and maintenance listed in Table D-l were developed from the
detailed cost breakdowns presented in Tables D-3 through D-6.
D-3
-------
DISPOSAL SITE MAINTENANCE AND MONITORING
Site O&M costs for upland and nearshore disposal, consisting primarily
of inspections, erosion control, repairs, and maintenance of site vegetation,
were estimated at $3,000/ac/yr based on data provided by U.S. EPA (1985).
Present worth of the O&M costs was estimated with a 10 percent discount for
30 yr.
It was assumed that a monitoring program involving physical, chemical,
and biological sampling would be conducted at each disposal site during
years 1, 2, 3, 5, 7, and 10 of operation. For the first year, sampling
would be conducted before the beginning of disposal activities to establish
baseline conditions. It is anticipated that long-term monitoring might be
necessary at the disposal sites. However, the impact on present worth of
monitoring costs beyond the first 10 yr would be minimal given the low
frequency of sampling events and the nature of present worth calculations.
Monitoring wells would be installed at the nearshore and upland disposal
sites for chemical monitoring. Ten wells were assumed for nearshore and
upland RCRA facilities accepting untreated sediments (excluding dewatering).
Six wells were assumed for upland facilities accepting treated sediments.
Once during each year specified above, two groundwater samples (replicates)
would be collected from each well for chemical analysis.
For open-water confined aquatic disposal, one sampling station would be
established for each 2 ac of disposal area. Once during each year specified
above, topography of the disposal area would be mapped for subsequent
sediment movement. One sediment core would be collected for chemical
analysis at each station and divided into three depth intervals. Five
benthic and three epibenthic samples would also be collected for biological
analysis.
For land treatment sites (not considered herein as disposal sites),
one well would be installed for each 25,000 yd-* of sediments disposed, with
a maximum of 15 and minimum of 6 wells per site. One groundwater sample
would be collected twice yearly from each well for years 1-5. Two ground-
water samples (replicates) would be collected every second year thereafter
through year 30.
The monitoring requirements discussed above were developed for the
purpose of cost estimation. Actual monitoring requirements will be developed
as part of remedial design and may differ from those presented here.
The unit costs for disposal site maintenance and monitoring shown in
Table D-l were calculated from the detailed cost breakdowns in Tables D-3
through D-6.
INTERTIDAL HABITAT MITIGATION
Intertidal habitat destroyed during removal of contaminated sediment by
clamshell dredging would be replaced with clean sediments from the Puyallup
River on a volume-to-volume basis. The two major cost items for intertidal
D-4
-------
habitat mitigation are use of the clamshell dredge and barge transport of
clean sediments.
MONITORING PROGRAMS FOR THE PROBLEM AREA
Post-remediation monitoring programs for the problem area were assumed
to include chemical and biological monitoring. Monitoring frequency would
vary with the remedial alternative. A one-time sampling event to confirm
removal of contaminated material would be conducted within the first 12 mo
following remediation involving removal and offsite disposal. The density
of monitoring stations and numbers of chemical and biological samples for all
post-remediation monitoring were assumed to follow that proposed for open-
water confined aquatic disposal (see above). Long-term monitoring would be
required for the institutional controls and in situ capping alternatives.
Monitoring programs for the former were assumed to include annual sampling
for 30 yr. Those for the latter were assumed to include two sampling events
per year for years 1-5, and then one sampling event in every other year
thereafter through year 30.
INDIRECT COSTS
A 20 percent contingency was applied on all cost items. A 10 percent
markup for mobilization, bonding, and insurance was added to the engineering
costs plus contingency. An additional 15 percent was applied to that total
for project administration, engineering design, and fee. However, neither
the 10 percent for mobilization/bonding/insurance nor the 15 percent for
administrati on/design/fee were added to O&M costs.
SPECIAL CONSIDERATIONS
The costs presented for St. Paul and Mouth of City Waterways incorporate
additional assumptions. For St. Paul Waterway, the area exceeding long-term
(i.e., target) cleanup goals was assumed to be the preferred area to monitor
for areas exceeding both long-term goals with 10 yr recovery and maximum
AET. By monitoring outside of the area that would be capped (i.e., the
preferred alternative) the resulting data will enable the location of the
cap to be monitored for movement.
The institutional controls monitoring program for Mouth of City
Waterway has been incorporated into the 10 yr and maximum AET O&M costs for
each alternative. The data generated by this monitoring program will help
verify that natural recovery is successful in the remediation of those
contaminated sediments.

FIELD SURVEY DATA REPORT - MAY 1986
COMMENCEMENT BAY NEARSHORE/TIDEFLATS FEASIBILITY STUDY
GENERAL APPROACH
The Commencement Bay Nearshore/Tideflats Feasibility Study (FS)
included field sampling, data compilation, and data interpretation. These
activities were undertaken to provide additional information regarding the
sources of problem chemicals to Commencement Bay and to characterize the
sources as historical or ongoing. Data collected during the FS will also be
used to evaluate the potential success of source control. The ultimate goal
of the FS is to provide an evaluation of various remedial actions for each
of the nine discrete problem areas. Effective remedial actions for
mitigation of sediment contamination problems will require a combination of
source control and sediment remedial actions.
Study Design
The study design for the Commencement Bay FS focused on measurements
of chemical contamination in surface and subsurface bottom sediments. These
sediments were analyzed for metals, semivolatile organic compounds,
pesticides, polychlorinated biphenyls (PCBs), total sulfides, percent total
organic carbon (carbonate-free), percent nitrogen, and grain size distribu-
tion. Selected sediment samples were also analyzed for tentatively
identified organic compounds, volatile organic compounds, and 210-Pb
activity. Results of these analyses are presented in Tables G-l through
G-27 (located following the references).
Station Locations and Sampling
During the Commencement Bay Nearshore/Tideflats Remedial Investigation
(RI) (Tetra Tech 1985), problem areas and problem contaminants were
identified and prioritized. Eight problem areas were assigned Priority 1 in
the RI. During the FS sampling, sediment cores were collected in each of
these areas. Four problem areas were assigned Priority 2 in the RI, and
sediment cores were collected in three of these areas during the FS. Two
additional problem areas, which were not assigned priorities in the RI, were
sampled during the FS. These areas were sampled because PCB contamination
was identified in Segment 3 of Hylebos Waterway, and slag contamination was
suspected in Segment 3 of the Ruston-Pt. Defiance shoreline. Comments on
specific station locations in the waterways and along the Ruston-Pt.
Defiance shoreline are discussed in the following section. Locations of
stations sampled during the Commencement Bay FS are shown in Figure 6-1.
Sampling dates, state plane coordinates, and water depths [corrected to mean
lower low water (MLLW)] of all stations are provided in Table G-28.
Briefly, station locations were selected to:
G-l
-------
Determine the historical pattern of contamination in sediments
in previously defined problem areas
Determine the depth of sediment contamination.- in previously
defined problem areas
Estimate sediment accumulation rates.
Sediment cores were collected at 23 individual stations in Commencement
Bay and along the Ruston-Pt. Defiance shoreline. At eight of these stations,
sediments were collected for 210-Pb analyses and contaminant and conventional
analyses. At three stations, sediments were collected only for 210-Pb
analyses, and at twelve stations sediments were collected only for con-
taminant and conventional analyses.
Contaminant and Conventional Analyses--
Sediment cores for contaminant analyses were collected at five stations
in Hylebos Waterway. Two of these stations (Stations HY-93 and HY-96) were
located in nearshore areas near the Occidental Chemical and Pennwalt
companies. Two additional stations (Stations HY-95 and HY-94) were located
in areas in which PCB contamination exceeded Apparent Effect Threshold (AET)
values. The remaining station (Station HY-91) was located in a primarily
metals-contaminated area at the head of Hylebos Waterway.
Along the Ruston-Pt. Defiance shoreline, sediment cores were collected
at five stations. Three stations (Stations RS-91, RS-92, and RS-93) were
located near the three main ASARCO outfalls. Although Station RS-92 was
shown inside the ASARCO loading dock in Figure 2 of the sampling and
analysis plan (Tetra Tech 1986a), it was not possible to move the sampling
vessel into this slip during the field survey. Therefore, Station RS-92 was
relocated as close as possible to the entrance of the slip. A fourth
station (Station RS-93) was located northeast of the ASARCO smelter along
the 60-ft depth contour. In the sampling and analysis plan, Station RS-93
was originally located in deeper waters near Tetra Tech Station RS-20.
However, Station RS-93 was relocated because rocks and shell fragments in
the sediments in the original location prevented the collection of an
acceptable vibratory core sample. The fifth station (Station RS-96) was
located off the Pt. Defiance fishing dock, near Tetra Tech Station RS-24.
Sediment cores were collected at Station RS-94 using both a vibratory corer
and a box corer. Because of coarse sediments and slag at Stations RS-91,
RS-92, RS-93, and RS-96, sediment cores were collected using only a vibratory
corer.
Sediment cores were collected at two stations in each of the following
waterways: Sitcum Waterway (middle and head), Middle Waterway (head and
mouth), City Waterway (head and south of the mouth of the waterway) and
Wheeler-Osgood Waterway (center and near the head). In the vicinity of the
St. Paul Waterway, sediment cores were collected at one station located as
close as possible to the Simpson/Tacoma Kraft mill and at a second station
located between Tetra Tech Stations SP-13 and SP-16.

-------
210-Pb Analyses--
Sediment core samples were collected for analyses at 12 stations (11
box core samples and 1 vibratory core sample) during the FS field survey
(Table G-27). Dredging records were used to locate stations in areas that
were not recently dredged. Stations were also located away from shorelines
and docks to avoid areas that may have been scoured by ship traffic. When
possible, sediments for 210-Pb analyses and contaminant analyses were
collected from the same core sample to enable the assignment of sediment
ages to contaminant horizons.
In Hylebos Waterway, sediment cores were collected for 210-Pb analyses
at three stations to provide an estimate of the range of accumulation rates
in that waterway. Single stations were sampled in Wheeler Osgood and
Sitcum Waterways, and two stations were sampled in City Waterway. In Middle
Waterway, stations were sampled at both the head and mouth of the waterway.
Station MD-91 was originally positioned closer to the head of Middle
Waterway. However, obstructions on the bottom prevented deployment of the
vibratory corer in this area.
In the Milwaukee Waterway, one station was sampled to provide informa-
tion on sedimentation in an area with negligible sources of solids other
than the Puyallup River. Because of the proximity of this station to the
Puyallup River, this core sample was expected to provide a reasonable
estimate of the upper limit of natural sedimentation in the Commencement Bay
waterways.
Along the Ruston-Pt. Defiance shoreline, sediment cores were collected
at only one of two stations identified in the sampling and analysis plan.
Station RS-93, located northeast of the ASARCO facility, was sampled.
However, sediment substrate (e.g., rocks, slag) precluded the collection of
an acceptable core sample in the area northwest of ASARCO.
CRUISE PROCEDURES
Cruise procedures used during the field investigations of the Commence-
ment Bay FS are specified in the sampling and analysis plan, the quality
assurance project plan, and the site safety plan (Tetra Tech 1986a,b,c).
Important aspects of these procedures are summarized below.
All sampling was conducted on board a flat-bottom barge. The barge was
moved to each predetermined coring location by a tugboat and anchored prior
to deployment of the sampling gear. A vessel-mounted, man-operated crane
was used to deploy and retrieve both the box corer and the vibratory corer.
During collection and initial processing of samples on board the barge,
precautions were taken to prevent sample contamination. Work areas of the
vessel were arranged to avoid contamination of samples by engine exhaust,
oil, and other interfering substances. Sampling gear was cleaned prior to
initiation of the field survey, and sampling utensils were routinely cleaned
throughout the survey to avoid cross-contamination of samples among stations
and sampling intervals.
G-6
-------
During the survey, a bound field logbook was maintained to record
important events, including any deviations from approved standard operating
procedures. Station location and sample description log forms were completed
for each station occupied and sampled. Chain-of-custody records and packing
lists were maintained for each sample collected. In this manner, sample
possession was tracked from the time of sample collection to the time of
sample delivery to the laboratory.
Station Positioning Methods
Station locations were determined using a marine sextant and line-of-
site fixes on stationary shoreline features. All sextant angles and line-
of-site fixes were taken from the same position on the vessel. To ensure
the accuracy of documentation of station locations, this position was placed
as close as possible to the position on the vessel where the sampling gear
was deployed. Sextant readings from the vessel were determined by measuring
the horizontal angles between two line-of-site fixes to three identifiable
targets whose positions were known. Line-of-site fixes were determined
using the field techniques described in the quality assurance project plan
(Tetra Tech 1986b). Photographic records were taken of all position
alignments at each station.
Upon completion of the survey, sextant angles were used to plot station
locations on U.S. Geological Survey quadrangle maps, U.S. Army Corps of
Engineers aerial maps (blue lines), and aerial photographs of the area.
These station locations were verified using photographic records and the
known water depths of the stations. In most cases, state plane coordinates
were determined directly from the maps for entry into the database. However,
in some cases station latitude and longitude coordinates were determined
from maps, and subsequently converted to state plane coordinates. These
station positioning methods were accurate enough to ensure definition of
station locations within at least a 40-ft radius.
HEALTH AND SAFETY
Procedures described in the site-specific safety plan for the Commence-
ment Bay Nearshore/Tideflats FS (Tetra Tech 1986c) ensured safe collection
of samples of adequate quality to meet contract specifications. The plan
specifically called for a modified Level D protection for sampling personnel.
Monitoring equipment included an HNu photoionization detector with 10.2 eV
probe and Drager tubes to monitor for the presence of hydrogen sulfide.
SEDIMENT CHEMISTRY
Procedures used for sampling and chemical analyses of bulk sediments
from Commencement Bay and the Ruston-Pt. Defiance shoreline are described
in the following sections. These procedures are generally in accordance
with the sampling and analysis plan and the quality assurance project plan
(Tetra Tech 1986a,b) developed for this project. Any deviations from the
procedures detailed in these plans are discussed below.
6-7
-------
Field Sampling
Sediment Samples--
Sediment core samples were collected at 19 stations using a 0.6-m^
Spade box corer (Appendix F). At 16 of these stations and four additional
stations, sediment core samples were also collected using a 6.1-m Alpine
vibratory corer with 3.5-in butyl liners. The box corer was used to sample
the near-surface sediments (0-50 cm) because it is most suitable for
recovering sediments from that depth (i.e., 50 cm) with minimal disturbance
of the sediment-water interface. The vibratory corer, which is unsuitable
for characterizing near-surface sediments, was used to collect the deeper
sediment cores. Because the stabilizing tripod of the vibratory corer
disturbs the surface of the bottom sediments, box core samples were collected
prior to vibratory core samples at each station. Sample collection methods
for these two types of sampling equipment are discussed separately below.
Box CorerPrior to initiation of the field survey, the box corer was
detergent-washed and steam-cleaned. During deployment of the box corer, the
sea surface was sprayed with a high pressure water hose to disperse any
surface contaminants that could potentially contact the inner portion of the
box corer. Following deployment and retrieval of the box corer, samples
were visually checked for acceptability. The major criteria for rejection
of a box core sample included:
Water leaking from the sides or bottom, or visible scour of the
surface near the edges of the sampler
Turbid water overlying the sediments
Insufficient maximum penetration depth (<22 cm).
When a sample exhibited evidence of these phenomena, it was rejected and a
new sample was collected.
After a core sample was accepted, the box corer was stabilized in a
vertical position and the water overlying the sample was carefully siphoned
off with an aspirator. The box containing the sample was then removed from
the box corer and placed on a nearly vertical stand designed for that
purpose. One side of the box was removed and the outer layer of sediment
was removed, allowing for an initial characterization of the sediment core.
Depth and qualitative descriptions of the color, texture, and odor of each
horizon were recorded on field log sheets, and a photograph of each core
sample was taken.
Once the descriptions were completed, a minimum of six discrete 2-cm
intervals were sampled from each core for sediment contaminants and
conventional analyses. Generally, the following intervals were collected:
0-2 cm, 2-4 cm, 5-7 cm, 10-12 cm, 20-22 cm, and the bottom 2 cm of the core.
The sampling intervals were positioned to ensure sampling of any distinct
horizons visible in the cores.
G-8
-------
At 11 stations, from 13 to 18 discrete 1-cm intervals were sampled from
each box core for 210-Pb analyses. The following intervals were commonly
sampled: 0-1 cm, 1-2 cm, 2-3 cm, 3-4 cm, 4-5 cm, 5-6 cm, 6-7 cm, 7-8 cm, 8-
9 cm, and 9-10 cm. Additional 1-cm sampling intervals varied among stations.
The following procedures were used to collect sediments from the box
core samples for chemistry analyses. Sediment subsamples for analyses of
volatile organic compounds, sulfides, and 210-Pb activity were collected
prior to any homogenization of sediments. Sediments for volatile organic
compound analyses were scooped from the core sample using a clean stainless
steel spoon. Sediments were then transferred into two 40-mL glass vials
with polytetrafluoroethylene (PTFE)-lined silicon septum caps. Care was
taken to ensure that no air space remained in the vials. Subsamples for
sulfides analyses were collected by transferring 5-10 g of sediment into
pre-weighed polyethylene cups containing 50-mL sulfur antioxidant buffer
(SAOB). Subsamples for 210-Pb analysis were taken by transferring approxi-
mately 20-g wet weight of sediment into pre-weighed polyethylene cups. All
210-Pb subsamples were collected at least 3 cm away from the side of the box
core. At eight stations, sediment subsamples for both 210-Pb analyses and
contaminants and conventional analyses were collected from a single box core
sample. At these stations, the aliquots for 210-Pb analyses were removed
from one side of the box core sample, and the aliquots for contaminants and
conventional analyses were removed from the opposite side of the box core
sample.
The remainder of the subsamples collected for contaminants and
conventional analyses were taken from homogenized sediments, and each
sampling interval of the box core sample was composited separately. For
each 2-cm sampling interval, the entire layer was carefully removed with a
clean stainless steel spatula, transferred to a clean stainless steel bowl,
and homogenized by stirring with a clean stainless steel spoon. Sediments
near the sides of the box core sample were not collected. Homogenized
sediment subsamples were collected as listed below:
250 ml was transferred to a precleaned glass jar with a PTFE
cap liner for semi volatile organic, pesticide, and PCB
chemical analyses
125 ml was transferred to a pre-cleaned glass jar for metals
analyses
125 ml was transferred to a pre-cleaned glass jar for total
organic carbon and total nitrogen analyses
75 ml was transferred to plastic bags for grain size analyses.
Total solids were analyzed by the laboratory as part of the extractable
organic chemical and metals analyses. All glass sample jars were pre-cleaned
(300 series) by I-Chem Research, Inc. The pre-cleaned polyethylene sample
containers were provided by the laboratories that performed the sulfide and
210-Pb analyses.
G-9
-------
Following sample collection, individual glass sample jars were placed in
plastic bags. All samples were stored in the dark on ice for transport to
the laboratory. Samples that were not delivered directly to the laboratory
were frozen (<-20° C), except for sulfide, volatile organic, and grain size
samples, which were refrigerated.
The stainless steel bowls used for homogenizing sediments were of
adequate size for compositing samples. Between sampling intervals of a box
core sample, the bowls and spatulas were washed with site water to remove
all residual particles, and then rinsed with pesticide-grade methylene
chloride. Between stations, the box corer was rinsed with site water, and
the sampling utensils were rinsed with site water, rinsed with methylene
chloride, and wrapped in aluminum foil.
An HNu photoionization detector and a hydrogen sulfide monitor were
used to monitor all sediment samples for harmful vapors. No problem vapors
we.re detected throughout the survey.
Vibratory CorerAfter the barge was anchored on station and box core
samples were collected, the vibratory corer was deployed as directed by the
field supervisor. To collect each core sample, the corer was activated for
an estimated 10 min. Once the vibratory corer was retrieved, the core liner
was removed from the core barrel and carefully placed in a horizontal
position. Sediments on the exterior surface of the core liner were checked
for vapors. The core sample was then examined for acceptability. The major
criteria for rejection of a vibratory core sample included:
Insufficient sampler penetration (less than or equal to the
penetration of the box corer)
Sample loss during retrieval of the corer
Evidence of core compaction in the surficial horizons
Evidence of severe disturbance (e.g., turbidity) at the
sediment-water interface.
When a sample exhibited evidence of these phenomena, it was rejected and a
new sample was collected.
After a core sample was accepted, the core was stabilized on a stand in
the horizontal position. The total length of the core was measured, and
plastic caps were placed on each end of the core liner to prevent sample
loss. The core liner was then cut into 4-ft sections using a pipe cutter,
and each 4-ft section was capped on both ends. Both the plastic caps and
the core liner were labeled with station and core section designations. The
core sections were then placed vertically in a refrigeration facility, or
were directly transferred to the sample processing area, as appropriate.
Sediment subsamples for chemistry analyses were collected from each
core section on board the sampling vessel or in a clean room on shore. To
process core samples, individual core sections were placed horizontally in a
G-10
-------
wooden trough that served as the core holder. The plastic caps were removed,
and an electric router was used to score opposite sides of the core liner
along its length. Plastic shavings were removed from the scored area using
a screwdriver and a whisk broom. A sharp knife was then used to completely
cut through the core liner, and the top half of the core liner was lifted
off the sediment and the remaining lower core liner. In some cases, an
alternative method was used. If the sediment appeared to be loosely
consolidated in the core liner, the sediment core was extruded from the core
liner by lifting up one end of the core liner. This allowed the sediment
core to slide into the wooden core holder. For each core section, the core
length, depths of color, odor, and textural horizons were recorded in field
log sheets. Based on these observations, sampling intervals were selected to
provide adequate sample volumes and to obtain horizons representative of any
major discontinuities in the core. A maximum of eight 15-cm intervals were
subsampled from each entire core sample, and sampling intervals were
generally separated by a minimum of 30 cm. For each sampling interval,
sediment subsamples for volatile organic compounds, sulfide, and 210-Pb
analyses were collected from unhomogenized sediments in the manner described
above for the box corer. To collect sediment subsamples for the remaining
contaminant and conventional analyses, the entire 15-cm interval was
carefully removed, nonhomogenized, and transferred to sample containers as
described previously. Sample handling and storage procedures also followed
those outlined previously.
Laboratory Analytical Procedures
Laboratory analytical procedures used for chemical analyses of bulk
sediments from Commencement Bay are described in the following sections.
These procedures are generally in accordance with the quality assurance
project plan (Tetra Tech 1986b) developed for this project. Any deviations
from the procedures detailed in that plan are discussed below.
Laboratory Analyses for Metals--
Sediments from 240 samples were analyzed for 22 inorganic metallic and
non-metallic elements by Versar, Inc. Samples were analyzed according to
methods specified in the U.S. EPA Contract Laboratory Program (CLP) Statement
of Work (U.S. EPA 1984). However, the use of a 1-g sample to 500-mL final
dilution volume resulted in detection limits greater than one-half the AET
values for antimony, beryllium, cadmium, silver, and thallium. Following
negotiations with U.S. EPA Region X (Muth, G., 16 July 1986, personal
communication), all of these elements except thallium were reanalyzed by the
laboratory using a 1-g to 200-mL dilution. In addition, sediments were
analyzed for antimony using graphite furnace atomic absorption (GFAA).
Laboratory Analyses for Organic Compounds--
Volatile Organic CompoundsThirty selected sediment samples were
analyzed for 35 Hazardous Substance List and U.S. EPA priority pollutant
volatile organic compounds. Samples were analyzed by Compuchem, Inc., a
U.S. EPA-approved Contract Laboratory, according to the methods for low-
concentration sediment samples as specified in U.S. EPA Contract
G-ll
-------
No. 68-01-6866. This method is based on purging a heated sediment sample
mixed with reagent water that contains the surrogate and internal standards.
Two sample containers, which were collected from Hylebos Waterway, developed
hairline fractures prior to shipment to the contract laboratory. These
samples were delivered frozen to Analytical Resources, Inc. (Seattle, WA)
and sediments were analyzed for volatile organic compounds using the CLP
procedures described above.
Sediment subsamples (5 g wet weight) were placed in a purging vessel,
sealed, and refrigerated until analysis. As allowed under the CLP, samples
were stored a maximum of 3 days prior to analysis. Prior to purging, 5 mL
of reagent water containing 25 ug of each of the following surrogate and
internal standards was added to the subsample: 4-bromofluorobenzene, dq-
1,2-dichloroethane, and dg-toluene as surrogates, and bromochloromethane,
1,4-difluorobenzene, and d5-chlprobenzene as internal standards. It is not
possible to determine whether significant loss of volatile organic compounds
occurred when the vessels were opened for addition of this reagent water.
The samples were then heated to 40° C and purged for 12 min. Volatile
compounds were trapped with a column containing a minimum of 1 cm of methyl
silicon coated packing, 15-cm Tenax porous polymer trap (60/80 mesh), and
8 cm of silica gel (35/60 mesh). Volatile compounds were desorbed from the
trap at 180° C for 4 min (20-60 mL/min) onto the gas chromatographic column
[Carbopack B (60/80 mesh with 1 percent SP-1000 with 2 mm i.d. x 6 ft)].
The GC oven was isothermal at 45° C for 3 min, and programmed for 8° C/min
to 220° C/min and held for 15 min. Both Finnigan and Hewlett-Packard GC/MS
systems were used for quantisation. Results were not recovery corrected.
Semivolatile Organic CompoundsSediment samples were analyzed for
65-68 semivolatile organic compounds by Enseco/Erco Laboratories (Cambridge,
MA). Analyses were performed under the Special Analytical Services (SAS)
Contract 2191J through the U.S. EPA CLP. The laboratory followed the 301(h)
protocols (Tetra Tech 1986e) and the SAS contract.
Tentatively Identified Organic CompoundsIn the Commencement Bay
Nearshore/Tideflats RI (Tetra Tech 1985), 12 tentatively identified organic
(TIO) compounds were searched for in extracts from surface sediment samples.
These 12 TIO compounds were an alkylated benzene isomer (identified as
cymene in the Commencement Bay RI), pentachlorocyclopentane, biphenyl,
dibenzothiophene, hexadecenoic acid, 1- and 2-methyl phenanthrene, isopimara-
diene, kaur-16-ene, 1-methyl pyrene, retene, and coprostanol. During the
FS, these TIO compounds were also searched for in extracts from 203 sediment
core samples (including 25 samples that were analyzed as replicate analyses).
In addition, sediment extracts were also searched for benzothiazole, which
has been used as a tracer compound for street runoff (Spies et al. 1987).
The following method was used to determine the concentrations of TIO
compounds (Seller, H., 20 January 1988, personal communication). Searches
for TIO compounds were made using a minimum of three ion plots (i.e., the
quantitation ion and two or more confirmation ion plots) in retention time
windows. The retention time windows were determined during the Commencement
Bay RI. If these ion plots indicated that a TIO compound was present, the
G-12
-------
spectra were examined. A computerized library of mass spectra was used to
facilitate compound identification. When compounds were confirmed, the peak
height and area of the quantitation ion were determined and recorded.
Concentrations of TIO compounds were estimated using the following
formula:
A x C
sample d,Q-phenanthrene
Ay DP
rtd1Q-phenanthrene * Kr
where:
Asample = Area under quantitation ion (base peak) for the compound of
interest in a sample
CdiQ-phenanthrene = Concentration of din-phenanthrene spiked into the
sample (assuming 100 percent recovery)
Adig-phenanthrene = Area of diQ-phenanthrene -jn sample
RF = [base peak intensity/total ion intensity] for TIO compound X
[base peak intensity/total ion intensity] for dig-phenanthrene.
The response factors (RF) were developed to account for the differences
in fragmentation patterns of dig-phenanthrene in relation to the TIO
compounds. Sample recoveries based on this formula are discussed in the
section on data evaluation for TIO compounds.
PCBs Analyzed bv GC/ECD--Ca1ifornia Analytical Laboratory (CAL)
analyzed 101 sediment samples for PCBs. Samples were analyzed using gas
chromatography/electron capture detection (GC/ECD) according to the methods
for low-concentration sediment samples as specified in U.S. EPA (1984,
revised in October 1986). From January 1987 through May 1987, instrument
detection limits for each Aroclor were provided for each date that samples
were analyzed. Therefore, CAL provided concentrations of total PCBs for
each sample, and separate concentrations of seven Aroclors for each sample.
Prior to analysis by CAL, all sediment samples were held in frozen
storage at the Enseco/Erco Laboratory (Cambridge, MA). After Enseco/Erco
completed all extractions for semivolatile organic compounds, the samples
were transferred to CAL. Between January and April 1987, CAL conducted
sample extractions for PCBs. The total holding times for these samples from
sample collection until analysis were within Puget Sound Estuary Program's
(PSEP) recommended guideline of 1 yr for frozen samples. According to the
U.S. EPA CLP, PCB extractions must be performed within 10 days of receipt of
refrigerated soil/sediment samples. Based on this requirement, CAL exceeded
sample holding times for 39 samples. However, because these samples were
stored frozen, it was not necessary to qualify the data.
G-13
-------
Although the U.S. EPA CLP method requires the use of the surrogate
compound dibutylchlorendate, this compound was not spiked into any samples.
Therefore, no surrogate recoveries were available for this data set. In the
quality assurance (QA) review of instrument performance, no problems were
identified in the observance of retention time window criteria, retention
time shift criteria, or observance of the 72-h analytical sequence in the
individual standard mixes.
PCBs Analyzed bv GC/MSGulf South Research Institute (GSRI) analyzed
101 samples for PCBs using gas chromatography/mass spectrometry (GC/MS)
according to U.S. EPA Method 680. GSRI received all the samples as extracts
from CAL. However, 9 of these 101 sample extracts were received from CAL in
an unfavorable condition (i.e., the solvent had evaporated). Therefore,
GSRI performed sediment extractions of original sediment material for these
nine samples. Four matrix spike extracts prepared by CAL were also
transferred to and analyzed by GSRI. GSRI did not analyze Samples CI-91B 5-
7, SI-91B 0-2, and HY-96A 32-47. The reason for this is not documented,
and may have been an oversight by the laboratory.
PCB analyses were performed on a Finnigan 4510 GC/MS/DS system operated
in the multiple ion detection (MID) mode. The requested method detection
limit (MDL) of 25 ug/kg dry weight of total PCBs (as Aroclor 1260) was
attained for most samples. These detection limits were raised during QA
review to account for the apparent loss of PCBs from extracts based on matrix
spikes.
GSRI received all extracts from CAL on 24 June 1987, and analyzed all
extracts by 13 July 1987. The extractions of original sediment material for
nine samples were conducted by GSRI on 26 June 1987. Thus, except for the
nine samples extracted by GSRI, extracts exceeded the U.S. EPA CLP 40-day
extract holding time requirement by at least 35 days. Based on the
considerable exceedance of extract holding times, all positive values for
CAL extracts were qualified as estimates (E) during QA review.
Instrumental tuning and performance of the GC/MS was evaluated during
QA review. An on-column injection of 10 ng decafluorotriphenylphosphine
(DFTPP) was conducted and GC/MS tuning criteria were met at the beginning of
each 12-h period that analyses were performed. During the five-point
initial calibrations, the percent relative percent difference (RPD) of PCB
congeners were within the limits of 20 percent RPD, with the exception of
seven standards. The values for these seven standards did not exceed 29
percent. During continuing calibrations, thirty congeners were outside of
response factor (RF) control limit criteria (< 20 percent). When criteria
were not met, the laboratory did not repeat analyses. Therefore, PCB
congeners detected in samples that had RFs outside of control limits during
initial calibration were assigned E qualifiers. The data qualifier E was
also assigned to results of congeners that exceeded the 20 percent RPD
criterion between initial and ongoing calibration.
Pesticides--CAL analyzed 209 sediment samples for the organochlorine
portion of the U.S. EPA Hazardous Substance List. Samples were analyzed
6-14
-------
using GC/ECD according to the methods for low concentration sediment
samples as specified in U.S. EPA (1984, revised in October 1986).
Pesticides were detected in 45 of the 209 sediment samples. Concentra-
tions of pesticides were generally very low (e.g., <50 ug/kg). Of these 45
psitive responses, 4,4'-DDT, 4,4'-DDE, and 4,4'-ODD were primarily detected.
Dieldrin, aldrin, . chlordane, and beta-HCH (an inactive isomer of the
pesticide gamma-HCH) were detected infrequently. The remaining 10 pesticides
on the U.S. EPA priority pollutant list were not detected at the detection
limits for these samples. The pesticides analyzed for in these sediments
are now either banned or severely restricted in use. These pesticides were
placed on the U.S. EPA priority pollutant list because of their high
toxicity, persistence in the environment, and potential for bioaccumulation.
The detection of low concentrations of pesticides in sediments collected
during the FS follows the trend observed in concentrations of pesticides in
sediments reported during the RI (Tetra Tech 1985). Tetra Tech (1985)
reported that DDT and its dechlorinated metabolites, DDE and ODD, were not
detected above 1 ug/kg in all sediment samples, regardless of sediment
depth. The relatively high levels of chlorinated pesticides reported to be
present in Commencement Bay in earlier reports (Johnson et al. 1983) were
not confirmed by Tetra Tech (1985). In the FS, similar observations of low
concentrations of pesticides in sediments, with the exception of two
locations of moderate concentrations (i.e., <500 ug/kg), suggest that these
pesticides are not major contaminants. However, because of their potential
hazard and ability to bioaccumulate, their presence in surficial sediments
of Commencement Bay may warrant continued monitoring. An anomalously high
concentration of aldrin in one location in Hylebos Waterway during the FS
sampling is presently unexplainable and was not observed in recent samplings,
although historical samplings have reported similar findings. The un-
certainty in historical detections of aldrin due to interfering substances
in the GC/ECD analysis has been discussed (Tetra Tech 1985). Results of
pesticides analyses in sediments are described below for each waterway
sampled in Commencement Bay.
City WaterwayPesticides were detected at all four sampling locations
in City Waterway, with 31 percent of the samples showing pesticide levels in
the ppb range. In all four locations, 4,4'-DDE and 4,4'-ODD were the major
pesticides detected, ranging from 8 to 30 ug/kg (dry weight) at 0- to 22-cm
depths. One location in this waterway (Station CI-91) had the most positive
responses for pesticides in Commencement Bay. The highest concentrations
ranged up to 380 ug/kg for chlordane, to 140 ug/kg for dieldrin, and to
480 ug/kg for ODD. Small amounts (38 ug/kg) of endosulfan sulfate, the
major persistent metabolite of endosulfan, was also detected at this
location.
Hylebos Waterway--Hylebos Waterway had fewer contaminated sites, with
four of seven locations showing detectable levels of pesticides in sediments.
One site (HY-96) was distinguished by the detection of relatively high
concentrations of aldrin at the sediment surface (7,400 ug/kg), decreasing to
approximately 20 percent of that value at a depth of 7 cm. These levels
were not observed at other sites in this waterway nor at other locations in
G-15
-------
Commencement Bay during the FS sampling. 4,4'-ODD, 4,4'-DDE, and 4,4'-DDT
were detected at the other three locations in Hylebos Waterway, which
included the head and midpoint sections of the waterway, at concentrations
slightly greater than those found in City Waterway and in somewhat deeper
sediments (10-30 cm).
Middle Waterway--The two locations sampled in Middle Waterway both
showed low levels of pesticides (0.5-14 ug/kg) in relatively deep sediments
(>20 cm). 4,4'-DDT, 4,4'-DDE, and 4,4'-ODD were the only pesticides
detected.
Sitcum WaterwayThe two sampling locations in Sitcum Waterway showed
low concentrations of 4,4'-DDT, 4,4'-DDE, and 4,4'-ODD (1-12 ug/kg) at
depths between 10 and 20 cm. Very low levels of 4,4'-ODD were detected at a
depth of 120 cm at one location. In addition, beta-HCH was detected at a
low concentration at the surficial level at one location.
Ruston/Pt. Defiance Shorelinepesticides were detected in three of the
four locations sampled. 4,4'-DDT was present in all samples at a wide range
of concentrations (0.4-140 ug/kg). At two sites (RS-94 and RS-91), 4,4'-DDT
was detected at low concentrations in deep sediments (>450 cm). Dieldrin
and aldrin were also detected at one site each at very low concentrations
(<1 ug/kg) and in relatively deep sediments (>60 cm).
Laboratory Analyses for Ancillary Variables--
Supplemental analyses were conducted for water-soluble sulfides, percent
total organic carbon, percent nitrogen^ grain size distribution (e.g.,
percent sand, silt, clay fractions), and 210-Pb activity in sediments.
Water-Soluble SulfidesWater-soluble sulfide analyses were performed
by Am Test, Inc. (Redmond, WA). There is no U.S. EPA-approved method for the
analysis of sulfide in sediments. Sediment samples were analyzed according
to the method described by Green and Schnitker (1974). Sulfides were
determined using a specific ion electrode and a 0.005 M or 0.05 H Pb(C104)2
titrant.
The samples analyzed in this study had relatively high sulfide
concentrations. Although the analytical laboratory was familiar with the
above-referenced method, they had not previously analyzed samples with such
high concentrations. Forty-nine of the 105 samples analyzed exceeded the
recommended 10-g weight limit resulting in sluggish probe and meter
responses. Equilibration of an individual sample took up to half a day.
The excessive time required for sample analysis affected the analysis
schedule, delaying sample analysis as much as 39 days beyond anticipated
dates. This delay resulted in exceedance of recommended holding times for
100 samples.
Total Organic Carbon and Total NitrogenSediment subsamples were
analyzed for total organic carbon and total nitrogen at the University of
Washington School of Oceanography (Seattle, WA). Subsamples were analyzed
within the 6-mo recommended holding time, according to the accepted PSEP
G-16
-------
methods specified in Tetra Tech (1986d), and described by Hedges and Stern
(1984). Subsamples were dried and treated with acid to remove carbonate
prior to combustion in a Carlo-Erba elemental analyzer.
Grain Size AnalysisSediment grain size was determined at the
University of Washington School of Oceanography (Seattle, WA) by sieve and
pipet analysis, according to accepted PSEP procedures (Tetra Tech 1986d).
Prior to analysis, samples were stored at 4° C, with the exception of 70 of
the 202 samples, which were inadvertently frozen for several days after
sample collection. A representative subsample (approximately 25 g) was
removed for total solids determination, and a second subsample was removed
for wet sieving and particle size analysis. Prior to wet sieving, the
subsample was oxidized with hydrogen peroxide to remove organic material.
All samples were analyzed within the recommended 6-mo holding time.
210-Pb AnalysisSediment samples were analyzed for 210-Pb activity,
percent solids, and dry density by Battelle Northwest Marine Laboratory
(Sequim, WA). Sediments for 210-Pb analysis were spiked with 208Po, freeze-
dried, and acid-extracted. The extract was plated on silver foil, and
measured for 210-Pb activity' (the alpha-emitting granddaughter isotope of
210-Pb) using alpha spectroscopy. Specific details of this method are
discussed in Carpenter et al. (1981). Dry density (g/cc) was derived from
an empirical relationship between wet sediment density and percent solids
that has been observed in Puget Sound samples by the Battelle Marine
Laboratory. Dry density refers to the total grams of solid material per cc
of wet sediment, not the density of sediments after drying (Crecelius, E.,
14 November 1986, personal communication).
QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)
Results of the QA review of analyses for inorganic and organic compounds
in samples collected during the Commencement Bay FS have been entered into
the Commencement Bay database and are summarized in the remaining pages of
this report.
Data Evaluation for Metals
All samples submitted to the laboratory were analyzed. All requested
reanalyses were performed by the laboratory with the following exception.
Twenty-four samples were not reanalyzed for cadmium, silver, antimony, and
beryllium. Sixteen of these samples had detection limits that exceeded
one-half of an AET value for at least one of these four elements. Results of
the metals analyses are presented in Table 6-1. The QA review is summarized
below.
Precision--
Precision of metals analyses was determined from a field duplicate for
Station SI-91 and a field triplicate for Station HY-93. For QC field
replicate samples submitted to laboratories, U.S. EPA does not specify
either control limits or corrective actions. However, the RPD control limit
for laboratory duplicates of solid samples is ħ35 percent (U.S. EPA 1985a).
6-17
-------
For the field duplicate, only beryllium exceeded this value. However, the
concentrations were less than five times the Contract Required Detection
Limit (CRDL). For the field triplicate, only cadmium and cobalt exceeded
+35 percent coefficient of variation (c.v.), and in both cases, the
concentrations were less than five times the CRDL.
Accuracy--
No standard reference material (SRM) samples were submitted to the
laboratory to determine the overall accuracy of the laboratories analyses.
However, under the terms of the CLP, the laboratory was required to analyze
calibration verification standards (post-digestion) and U.S. EPA laboratory
control samples (pre-digestion). Calibration verification standards were
analyzed at the beginning of over 20 analytical runs. All results were
within the CLP percent recovery control limits of 80-120 percent for
mercury and 90-110 percent for all other elements. Over 20 laboratory
control samples were analyzed, and all results were within the CLP percent
recovery control limits of 80-120 percent. No laboratory control sample
analysis is required for mercury.
During the U.S. EPA contract compliance screening procedures, seven
transcription and six calculation errors were discovered and corrected in
the original data.
Blanks--
Data values were corrected for blank contributions.
Data Qualifiers--
Based on the U.S. EPA contract compliance screening, six of the batches
of samples analyzed required the flagging of some results due to non-
compliance in the inductively coupled plasma (ICP) serial dilution tests.
Summary--
The original data as corrected and the reanalyzed data are of acceptable
precision and accuracy as defined by U.S. EPA (1985a). No results were
rejected during the U.S. EPA contract compliance screening of the original
data. Overall, there are no indications of any limitations on the use of
the data.
Data Evaluation for Volatile Organic Compounds
Data were evaluated according to the U.S. EPA laboratory data validation
guidelines (U.S. EPA 1985b). No data were qualified according to the data
validation guidelines. Results of analyses for volatile organic compounds
are presented in Tables G-2 through G-9, and QA issues are presented below.
6-18
-------
Precision--
No replicate samples were collected in the field. The laboratory
performed two sets of duplicate matrix spike analyses. All results were
within control limits.
Accuracy--
Matrix spike results were within control limits for all analyses (two
sets of duplicate matrix spikes).
Blanks--
Methyl ene chloride and acetone were the only contaminants detected in
the method blanks. Methylene chloride was detected in the blanks at con-
centrations ranging from 10 to 70 ng on-column. Concentrations of acetone
ranged from 31 to 90 ng on-column. As specified in the U.S. EPA CLP data
validation guidelines (U.S. EPA 1985b), concentrations of methylene chloride
and acetone are not reported if sample concentrations are less than 10 times
the concentrations in the blanks. Most of the samples contained less than
10 times the blank concentrations and, therefore, no methylene chloride or
acetone values are reported.
Two empty sample containers were submitted to the laboratory for
analysis. One container was opened onsite and then sealed, and one remained
closed as received by I-Chem Research, Inc. The concentrations of methylene
chloride and acetone detected in these blanks were within the range of
concentrations detected in the method blanks. Based on these data,
contamination from sample containers or field operations is not suspected.
Data Evaluation for Semivolatile Organic Compounds
Mass spectra were examined in detail for semivolatile organic compounds
that were detected less than four times and for semivolatile organic
compounds that are not typically found in environmental samples (e.g., 3,3'-
dichlorobenzidine). Based on these examinations, values were changed for
the following four compounds which were apparently misidentified in six
samples: 3,3'-dichlorobenzidine, 2-nitrophenol, 2,6'-dinitrotoluene, and 2-
chloronaphthalene. Results of analyses for semivolatile organic compounds
are presented in Tables G-10 through G-20. QA issues are presented below.
Precision--
Data for one field analytical triplicate, six laboratory analytical
duplicates, and two laboratory analytical triplicates were used for precision
analyses. These 12 additional analyses resulted in an overall frequency of
6 percent for replicate analyses.
The c.v. ranged from 0 to 161 for compounds detected in all three
replicates from the triplicate analyses and both replicates from each of the
duplicate analyses. The mean c.v. was 51 for low molecular weight poly-
nuclear aromatic hydrocarbons (LPAH), 47 for high molecular weight poly-
6-19
-------
nuclear aromatic hydrocarbons (HPAH), 39 for phenols, and 78 for phthalates.
Of the 42 compounds not consistently detected within a replicate, 10 com-
pounds were detected at concentrations greater than two times the limit of
detection. Precision is expected to be poorer near the limit of detection.
The laboratory identified two samples as having low recoveries of the
internal standards. Results of analyses of other samples from the same core
were examined to determine whether there was a trend of low recoveries, which
might suggest a matrix effect. No trends were noticed, and recoveries were
greatly improved following re-extraction of these samples by the laboratory.
Accuracy--
There are no certified reference materials [e.g., standard reference
materials (SRM)] available for organic compounds in marine sediments. Two
locally available reference sediments, Duwamish River 3 and Sequim 1, which
contain PAH were provided by National Oceanic and Atmospheric Administration
(NOAA) and National Marine Fisheries Services (NMFS), and were submitted for
analysis. The laboratory analyzed one sample of Duwamish River 3 and two
samples from Sequim 1 reference materials. These resultant values were
compared with the mean concentrations of organic compounds provided by NMFS
and NOAA for the Duwamish River 3 material, and the average of the two
single analyst means provided for the Sequim 1 material. The accuracy
between these samples ranged from 3 to 79 percent for the Duwamish River
material, and from 23 to 83 percent for the Sequim material.
The laboratory also analyzed an archived sample that had been collected
at Station CI-17 during the Commencement Bay RI in March 1984. This sample
had been analyzed in duplicate by a similar method during the laboratory
analyses conducted as part of the RI. The agreement between results
obtained for analyses of this sample during the FS and those obtained during
the RI is not as good as the agreement for the NOAA reference materials. No
apparent reason for this discrepancy could be determined.
During a minimum 10 percent QC check, no transcription errors were
detected, although several calculation errors were detected and corrected.
Blanks--
Method blanks were analyzed with each extraction batch. Many compounds
were detected at relatively low levels in several of these blanks. Benzoic
acid, naphthalene, di-N-butylphthalate, bis(2-ethylhexyl)phthalate, phenol,
4-methylphenol, and N-nitrosodiphenylamine were detected at a level exceeding
the control limit of 2.5 ug total (5.0 ug total for phthalates) in some of
the blanks. The concentrations of these compounds ranged from the limit of
detection to two or three orders of magnitude greater than the limit of
detection.
Although no specific source of contamination was confirmed, the high
concentrations of these compounds in samples can best be explained by sample
carryover in the laboratory. The data for the compounds found in an
G-20
-------
associated blank were qualified with either a B or a Z to show blank
correction was performed.
Data Qualifiers--
For entry into the database, the following qualifiers were used where
appropriate:
U = Undetected at detection limit shown
Z = Corrected for blank, resultant value is greater than the required
limit of detection for that compound
B = Corrected for blank, resultant value is less than or equal to the
required limit of detection for that compound
E = Estimated value
X = Isotope labeled standard recovery <10 percent, applied to detected
compounds only.
Detection LimitsThe lower limits of detection (LLD) in the first set
of 40 samples were overestimated by the laboratory. These LLD were adjusted
during QA review to be consistent with the second through fifth data sets
in which the laboratory reported detection limits based on 1) an instrumental
detection limit of 1 ng for most compounds; 2) dry weight of sample;
3) 400 uL final volume of extract: 4) 2 uL injection volume; and 5) 3/8 of
the sample lost on the automated gel permeation chromatography (6PC) system.
During data review, recovery of the labeled compounds was taken into
account. This method of LLD estimation is expected to yield values similar
to those obtained by use of the guidelines recommended for the 301(h)
monitoring programs (jetra Tech 1986e). Based on the recovery results and
the laboratory detection limits, two levels of LLD for the compounds in each
sample were established. The higher level of LLD was applied to 2,4-
dimethylphenol and 2,4-dinitrophenol in all data, and to bis(2-chloroiso-
propyl) ether, benzylalcohol, benzoic acid, and 4,6-dinitro-2-methyl phenol
in three data sets.
Summary--
QA problems documented for analyses of semi volatile organic compounds
were resolved by correction of reporting errors, and corrections of
misidentified compounds. Polychlorobutadiene (PCBD) analyses had no method
blanks associated with them, nor were counts displayed on the selected ion
chromatograms displayed for the PCBD analyses. This prevented transcription
and calculation verification.
The laboratory followed the 301(h) protocols (Tetra Tech 1986e) and the
subcontract with the following exceptions:
Calibration control limits were exceeded for many compounds
without recalibration
G-21
-------
High concentrations of many compounds were reported in the
method blanks without stopping analyses while trying to
identify the source(s) of contamination.
No other problems that might limit the intended use of these data were found.
Data Evaluation for Tentatively Identified Organic (TIP) Compounds
Results of analyses for TIO compounds are presented in Table G-21. QA
issues are presented below.
Accuracy--
The RF formula, as discussed in the methods section of this report,
effectively recovery-corrected compounds based on the recovery of dig-
phenanthrene. It is unlikely that applying the recovery of diQ-phen-
anthrene to each TIO compound is appropriate. For compounds that are
similar to PAH (e.g., retene and 1-methyl pyrene), recoveries were probably
similar to diQ-phenanthrene. For compounds that are more polar (e.g.,
hexadecenoic acid), the recovery correction was likely an underestimate.
Overall, recovery corrections can be considered conservative.
Blanks--
TIO compounds were not observed in the two blanks that were examined.
Data Qualifiers--
All detected values were qualified as estimates to account for the
method of recovery correction and for the absence of authentic standards for
calibration. Undetected TIO compounds were denoted with a U, and an
associated detection limit was not listed. Sufficient information was not
available to estimate detection limits.
Data Evaluation for PCBs
Concentrations of total PCBs are presented in Table 6-22 and concentra-
tions of the individual Aroclor isomers are presented in Table G-23. CAL
and GSRI laboratories reported analytical results as total PCBs. CAL also
reported data for each of seven Aroclors. The QA review of these data was
performed by PTI, Inc. (Torres, A. and H. Beller, 30 November 1987 and 1
December 1987, personal communication). Precision and accuracy determin-
ations are summarized below for each laboratory.
Precision--
CAL--Four laboratory duplicates, three laboratory triplicates, one
blind duplicate, and one blind triplicate were analyzed by CAL. PCBs were
detected in only four of these replicate samples, and precision ranged from
2 to 63 percent RPD. Because precision criterion for PCBs are not defined
by CLP protocols, PSEP protocols were used to define precision control
G-22
-------
limits (i.e., <100 percent). All samples with detected concentrations of
PCBs were within PSEP criterion.
Analytical results for the triplicate Sample CW-91B 5-7 were unusual.
Results of two replicate samples were identical (1,000 ug/kg dry weight of
PCBs). PCBs were undetected (detection limit=400 ug/kg dry weight) in the
third replicate sample. The laboratory did not provide an explanation for
this occurrence and none is readily apparent.
GSRI--TWO sets of duplicate samples that were prepared by CAL were
analyzed by GSRI. As determined by RPD, precision ranged from 4.7 to 100
percent for congeners detected in these four replicate samples. Most of
these values were near detection limits. Precision for detected congener
groups ranged from 4.7 to 33 percent in Sample HY-94B 20-22, which is the
only moderately contaminated sample. The PSEP precision criterion (<100
percent RPD) was met for all samples in which target compounds were detected
in all replicates. Precision for CAL duplicates in which PCBs were detected
in all replicates ranged from 2 to 63 percent RPD.
GSRI also performed a blind triplicate analysis of Sample HY-93B 20-22.
GSRI extracted one of the three replicate samples, and the remaining two
replicate samples were received by GSRI as extracts prepared by CAL. The
RPD for three congener groups ranged from 13 to 52 percent. The PSEP control
limit (<100 percent RPD) was met for all PCB congener groups that were
detected in all three replicates. For this sample, the loss of PCBs from
extracts prepared by CAL is not indicated (see discussion below).
Accuracy--
CALEight PCB matrix spikes, four method blank matrix spikes, and one
method blank matrix spike duplicate were analyzed by CAL in this sample
case. Recoveries ranged from 64 to 92 percent in sediment matrices. All
percent recovery results for Aroclor 1254 were within PSEP control limits
(i.e., >50 percent).
GSRI--Extracts of four matrix spike samples, which were prepared by
CAL, were analyzed by GSRI. GSRI matrix spike recoveries were low, ranging
from 1.6 to 33 percent. When these same matrix spikes samples were analyzed
by CAL using packed column GC/ECD, recoveries ranged from 19 to 92 percent.
All GSRI matrix spike recoveries were below the PSEP control limits for
accuracy (i.e., 19-50 percent for different compounds). Based on analytical
results from CAL, the recovery for extraction and cleanup was good and would
not account for the low matrix spike results reported by GSRI. Two possible
explanations for these results are that 1) PCBs were lost (e.g., by
volatilization) from extracts during storage and transport, or 2) the GC/MS
quantification procedure underestimates the presence of PCB concentrations.
The loss of PCBs from extracts cannot be proven or disproven. However, GSRI
laboratory personnel noted that the sample extracts received from CAL
appeared to be in good shape (except for the nine samples that were re-
extracted by GSRI). The possibility that GC/MS quantification resulted in
underestimation cannot be rigorously tested because the extract spiking
analyses recommended for testing this factor were not performed. Moreover,
G-23
-------
although GSRI was requested to split several specified extracts and to spike
one portion of the extracts with a known amount of PCBs, these analyses were
not performed. Results of spiked analyses would be necessary to discern the
accuracy of quantitative analysis as distinguished from accuracy for matrix
spikes prepared by CAL.
For the four matrix spike samples analyzed by both GSRI and CAL, the
average recovery for CAL was 6 times greater than the average recovery for
GSRI. Therefore, GSRI detection limits were increased during QA review from
25 ug/kg dry weight to 150 ug/kg dry weight to account for the difference in
matrix spike results. GSRI detection limits were qualified as EU instead of
U to account for this correction factor. In addition, all positive results
for CAL extracts analyzed by GSRI were qualified with a G (greater than) to
account for the likelihood of underestimation, based on the low matrix spike
recoveries reported by GSRI. Concentrations of PCBs that were detected by
GSRI were not corrected with a factor of six because this factor was not
considered accurate enough to alter quantified concentrations on a sample-
by-sample basis.
The apparent low recoveries of PCBs by GSRI were explored further using
analytical results from Commencement Bay samples. The ratio of PCB
concentrations (CAL:GSRI) was compared for two groups of samples: Group 1-
samples extracts that were prepared by CAL and analyzed by both labora-
tories, and Group 2 - samples that were extracted separately by the
laboratories. For Group 1, the mean ratio of CAL to GSRI was 16, which is
significantly (p>0.05) higher than the mean ratio of 3.4 for Group 2. The
median ratio of Group 1 is 6.4 and the median ratio of Group 2 is 1.4.
These results indicate that CAL's analytical results were higher than GSRI's
results. However, the magnitude of the difference between results was less
when GSRI prepared their own sample extracts. This information suggests
that loss from extracts may have been an important factor in interpreting
the low recoveries determined by GSRI. The differences between results
determined by the two laboratories should not be overinterpreted because
neither laboratory has the absolute or true concentration. However, it
should be noted that between the two laboratories, the median ratio of
sample results was fairly consistent with the mean ratio of matrix spike
results (for which the absolute concentration was known).
Performance Evaluation and Reference Samples--
CALNo Performance Evaluation (PE) samples were analyzed by CAL.
Three Puget Sound reference samples (i.e., DR-3, SQ-1, and CI-17R) were
analyzed. The RPD among these samples ranged from -164 to 149 percent with
identical results (i.e., 0 percent RPD) for Sample SQ-1.
GRi--Two PE samples (i.e., Sample A = Aroclor 1254, Sample B = Aroclor
1242) were analyzed by GSRI. The samples were obtained through the
Environmental Monitoring Systems Laboratory (Cincinnati, OH). The certified
values for these samples were based on Aroclor-matching quantification with
packed column GC/ECD. The GSRI results for total PCBs were compared with the
certified concentrations of PCBs in the PE samples. Results of GSRI's
G-24
-------
analyses for total PCBs were within the relatively broad 95 percent
confidence intervals established for the certified values.
Blanks--
CAL--No target compounds were detected in any of the blanks.
GSRI--NQ target compounds were detected in the single laboratory blank
that was analyzed. The laboratory blank was run in conjunction with the
nine samples that were extracted by GSRI.
Data Qualifiers--
CAL Detection LimitsMinimum attainable detection limits for each
sample were apparently calculated by incorporating the on-column instrument
detection limit for the analyte of interest, the total extract volume, the
injection volume, and the sample wet weight. Conversions to dry weight were
made during QA review by multiplying the wet weight values by two (i.e.,
assuming 50 percent moisture; the average percent moisture for all samples
analyzed by both CAL and GSRI was 49 percent). The laboratory assigned an E
(estimated) qualifier to positive results if these conversions resulted in
concentrations that were below the minimum detection limit for that sample.
In some samples, interferences precluded detection of PCBs in certain
portions of the chromatograms. For these cases, the laboratory reported
higher detection limits for the corresponding Aroclors. Approximately 25
percent of all reported detection limits were >150 ug/kg dry weight and
approximately 15 percent were >1,000 ug/kg .dry weight. Extremely high
detection limits (e.g., 50,000 ug/kg wet weight) were determined for some
samples.
For all samples, if the percent difference between calibration factors
during the 12-h period was greater than 15 percent for any Aroclors that
were quantified, the data qualifier E was assigned to all positive data. If
the percent difference was greater than 20 percent for the confirmation
column, the results were also qualified as estimates (data qualifier E).
Because laboratory analyses exceeded continuing calibration criteria, the
data qualifier E was assigned to approximately 70-75 percent of the positive
values in this sample case. The laboratory attributed the fluctuations in
response to column degradation resulting from complex sample matrices.
In addition to these data qualifiers, all positive results were
qualified with a G (greater than) to account for the likelihood of under-
estimation, based on the low matrix spike recoveries reported by GSRI. This
issue was discussed previously in the Accuracy section.
GSRI Detection Limits--Based on the considerable exceedance of extract
holding times, all positive values for CAL extracts that were analyzed by
GSRI were qualified as estimates (E) during QA review. The following
qualifiers have been assigned to the GSRI data:
G-25
-------
EU - The target compound was not detected in the sample at the estimated
detection limit shown. The detection limit accounts for the poor
recovery observed in matrix spike samples (see the previous section
for a discussion of the reasoning).
E - The associated value is considered an estimate because QC criteria
were not met. These qualifiers were superceded by G, as described
below.
G - The reported value is considered an underestimate based on matrix
spike results (applied to all results for CAL extracts).
Summary--
CAL--These data are considered acceptable as qualified (Torres, A. and
H. Seller, 1 December 1987, personal communication). Based on U.S. EPA CLP
criteria for ongoing calibration, E qualifiers were applied to approximately
70-75 percent of the detected PCB values. The surrogate compound (i.e.,
dibutylchlorendate) specified for the CLP method was not added to any
samples. Therefore, matrix spike recoveries were the primary variable used
to assess accuracy. Accuracy based on matrix spikes was acceptable (i.e.,
64-100 percent). Detection limits for relatively clean samples were
acceptable for the purposes of these data. However, interferences in some
samples resulted in extremely high detection limits (e.g., 50,000 ug/kg wet
weight). Approximately 25 percent of all reported detection limits were
>150 ug/kg dry weight and approximately 15 percent were >1,000 ug/kg dry
weight.
GSRI--Matrix spike recoveries reported by GSRI ranged from 1.6 to 33
percent. These values are below the PSEP control limit. The recoveries
reported by CAL for these same extracts ranged from 79 to 92 percent. Based
on the low matrix spike recoveries determined by GSRI, the detection limits
for samples extracted by CAL were increased and qualified as EU and the
detected values were qualified with G. Based on the considerable exceedance
of holding times, all positive values determined by GSRI for extracts
prepared by CAL were qualified as estimates. No definitive explanation was
identified for the low "recoveries" in matrix spike extracts that were
prepared by CAL and analyzed by GSRI. However, a comparison among matrix
spike and PE sample results suggest that loss from the extracts during
storage and transport is the most plausible explanation. The recoveries for
the PE samples, which were extracted by GSRI, were considerably higher than
the recoveries determined by GSRI for the matrix spike samples that were
extracted by CAL.
CAL and GSRI--Comparisons among analytical results from CAL and GSRI
were prepared by A. Torres and H. Seller (30 November 1987, personal
communication). As recommended by PTI (Seller, H., 2 December 1987,
personal communication), the following method was recommended for integrating
the total PCB data that were received from both CAL and GSRI:
All detected CAL data (as qualified) were used
G-26
-------
If total PCBs were undetected by CAL, but were detected by
GSRI, the total PCB value from GSRI (as qualified) was used
If PCBs were undetected by both CAL and GSRI, the lower of
the two detection limits was entered in the database.
-Data Evaluation for Pesticides
Because of time and financial constraints, pesticide data for the FS
sampling effort have not been subjected to a formal QA review. Based on the
relatively low values observed in the problem areas, pesticide compounds are
not regarded as priority contaminants in the Commencement Bay Nearshore/Tide-
flats problem areas. Because the results of the pesticide analyses have not
been formally reviewed for QA, the data have not been tabulated. Raw data
as received from the laboratory are available in the Commencement Bay FS
project files.
Data Evaluation for Hater-Soluble Sulfides
Results of analyses for sulfides are presented in Table G-24.
Precision--
Precision of sulfide analyses was determined from three field tripli-
cates and two field duplicates. Results of the duplicate and triplicate
analyses are shown below:
Water-Soluble
Sample Sulfide (UQ/Q)
HY-93B 20-23 2,600
HD-93B 20-23 2,000
HT-93B 20-23 400
SI-91B 5-7 290
SD-91B 5-7 640
The triplicate samples were analyzed by the laboratory at the same time, and
the duplicate samples were analyzed at different times. The disparity in
sulfide concentrations may merely reflect natural variability related to
spatial variability in the area of sample collection, or it may be a result
of the exceedance of holding time limits. It is not possible to draw
conclusions from the limited data available.
Analytical error for sulfide analyses is monitored by evaluating probe
response. Two sulfide standards of a specified amount [i.e., X and (1/10)X]
are prepared in 50 ml of the SAOB solution. The millivolt (MeV) span between
the two solutions must be within 29+2 MeV to be acceptable. MeV spans for
the duplicate and triplicate analyses were within acceptable limits (i.e.,
30.2 and 29.1 MeV, respectively).
As discussed previously, sample weight has a pronounced effect on probe
response time. The duplicate samples were analyzed using a 9 g and a 20 g
G-27
-------
sample. The analytical results of the 9 g sample were much lower than the
results obtained for the 20 g sample. This suggests that the disparity in
the observed concentrations may be a result of sample size related to probe
response.
Approximately the same weight of sample was analyzed for each sample in
the field triplicates. Samples that contained high concentrations of
sulfides required dilution to observe a probe response. The sample with the
lowest sulfide concentration sample required little dilution to provoke a
probe response. The variability observed in these results is probably a
result of natural spatial variability.
Calibration data and raw data were not provided by the laboratory. No
method blank analyses are possible for this method. The titration of a
water sample would result in immediate MeV response upon the addition of the
first drop of titrant.
Accuracy--
No raw data was supplied to allow for either a calculation check in
converting volume of titrant used to ug/g sulfide or an analysis of trans-
cription error in the raw to summary data conversion. No SRM was submitted
by Tetra Tech to determine the accuracy of these analyses.
Summary--
The overall quality of this data set is acceptable for the intended use
of the data. These data will be applied as a qualitative indication of
anaerobic conditions at the depths and sites surveyed. The analytical
method used for these analyses is still in a developmental phase, but
represents the application of current state-of-the-art knowledge to a
difficult analytical task.
Data Evaluation for Percent Total Organic Carbon and Percent Nitrogen
Results of analyses for total organic carbon (TOC) and total nitrogen
(TN) are presented in Table G-24.
Instrument Calibration--
Continuing calibration check data are automatically incorporated into
the regression equation programmed into the analyzer. However, continuing
calibration check sample results are also monitored by the analyst. Samples
were reanalyzed if the instrument was observed to drift between initial
standards and check standards inserted in the run. Samples were also
reanalyzed if in-house duplicate sample results (one duplicate analyzed in
every two batch runs) were not acceptable. The basis for acceptability was
a decision by the analyst based on sample type and instrument response. All
samples requiring reanalysis were redone and the final results reported on
the summary data sheet.
G-28
-------
Precision--
Field duplicate and triplicate samples were collected and submitted to
the laboratory for analysis. The field duplicate was split by the laboratory
to provide an analytical duplicate and thus a mixed laboratory and field
triplicate. The laboratory also split two samples to be analyzed as known
triplicate samples. The laboratory did not analyze the known triplicate
samples within the same batch, but spread them over many batch runs to
incorporate run-to-run variability in the results.
Results of these replicate analyses are presented in Table G-29. It
should be noted that two of the blind triplicate samples were broken when
received by the laboratory. Although this did not apparently affect the
results of organic carbon analyses, the results of the organic nitrogen
analyses may have been affected by the broken sample containers. The percent
nitrogen value for the two samples in the broken containers was lower than
that of the intact sample. It is likely that the volatile components of the
samples (e.g., N-Nfy) were lost when the containers were broken.
Accuracy--
No SRM was submitted by Tetra Tech to determine the accuracy of these
analyses. The laboratory did not provide the results of in-house reference
standards. No statement can be made concerning the accuracy of this
analysis based on the information provided.
Twenty of the 203 samples (i.e., 10 percent) were evaluated for
transcription errors, and no errors were found.
Summary--
The overall quality of this data set is acceptable. There is nothing
to indicate any limitations on the use of this data. Broken sample
containers may have had an effect on results of five analyses. The five
samples received by the laboratory in broken sample containers are identified
in the comments section of the database.
Data Evaluation for Grain Size Determination
Results of analyses for grain size determinations are presented in
Tables G-25 and G-26. The recommended sample size for grain size analysis
is between 5 and 25 g. Sample weights less than the 5-g limit may result in
lower analytical accuracy because experimental error in weighing becomes
large in relation to sample size. Twenty-nine of the 202 samples analyzed
had sample weights that were below the 5-g limit. Nineteen of these samples
were reanalyzed using sample weights between 5 and 25 g. However, five of
these samples still were below the 5-g lower weight limit. The remaining 10
samples under the 5-g limit did not have enough sample to reanalyze, and
these are identified in the database.

G-30
-------
Precision--
Three samples were received by the laboratory as blind triplicates. An
additional set of two samples were received by the laboratory as a blind
duplicate. These two samples were paired with a laboratory split sample to
yield a triplicate sample set. Three additional samples were analyzed in
-triplicate, but were known to laboratory personnel.
Percent recovery was calculated for triplicate analyses. Percent
recoveries for individual QC samples ranged from 95.9 to 103.6 percent. The
range of mean percent recoveries for the triplicate sets was 97.3-101.4
percent. Routine sample percent recovery values ranged from 90.45 to 104.82
percent. The lowest mean percent recovery was obtained on the blind
triplicate set of samples. This may be an indication that laboratory
personnel were more careful analyzing known QC samples than during the
analysis of blind or routine samples. However, the blind duplicate results
of the mixed paired triplicate set were very close.
Percent silt and clay fraction were calculated for QC samples.
Coefficients of variation ranged from 2.4 to 8.7 for percent silt determi-
nations, and from 2.8 to 37 for percent clay. The precision of the blind
replicate samples was the least for both percent silt and percent clay in
comparison to the known triplicate sample results, supporting the idea that
technician care of known QC samples may have influenced analytical results.
c
Accuracy--
No SRM was submitted by Tetra Tech to determine the accuracy of the
grain size analyses. The laboratory did not provide results of analysis of
an in-house standard particle-size sample. The overall accuracy of the
grain size analysis was estimated by calculating the sum of all the
fractional weights as a percentage of the total weight of the sample before
manipulations. The mean percent recovery calculated from a subsample of 46
of the 202 samples was 98.9 percent (SD=2.9). A scatter diagram was
constructed, and no correlations were observed between the sample weight and
the percent recovery for this analysis.
Thirty-three samples of the 202 samples analyzed (i.e., 16 percent),
were evaluated for transcription errors. Two transcription errors were
found in addition to one unrecorded value. For 27 of 33 samples, an extra
entry for the -2.00 phi column was noted. Three transposition errors were
also discovered in the data set, and one value was not recorded from the
laboratory data sheet to the computer data file. In addition, two extra
values were recorded in the -2.00 phi column.
Summary--
The three factors that influence the overall quality of this data set
are 1) a high proportion of transcription error was observed during a
systematic review of the data; 2) a disparity exists between blind triplicate
and known triplicate results, which suggests that the care taken by
technicians performing routine analyses may be less than that used during
G-31
-------
known QC sample analysis; and 3) 70 of the 202 samples analyzed (i.e., 35
percent) were frozen prior to analysis. The third factor is the most
critical. Freezing of samples may cause particles to break apart resulting
in an analytical bias toward the smaller size classes. However, there is no
data indicating that this problem affects the quality of the analytical
data. Overall, the quality of this data set is acceptable within the
limitations previously discussed.
Data Evaluation for 210-Pb Analyses
Results of analyses for 210-Pb activity are presented in Table G-27.
Samples for 210-Pb activity were collected at all stations (see Table G-28).
Precision--
Triplicate analyses were conducted on five sediment samples. Results
of these analyses are shown in Table 6-30. Two of the five RPD reported for
the triplicate samples exceeded the 10 percent RPD value identified in the
quality assurance project plan (Tetra Tech 1986b).
Counting statistics represent the uncertainty in the instrumental
measurement of 210-Pb activity, the granddaughter product of 210-Pb.
Counting statistics are a function of the number of counts due to the sample
and the number of counts due to background. The length of time that a
sample is counted will alter the measurement precision. Although counting
statistics were not reported in the data package received from the labora-
tory, each sample was reportedly counted until a total of 600-1,000 counts
had accumulated, which is approximately equivalent to a precision of 3 to
4 percent (Crecelius, E., 14 November 1986, personal communication).
Accuracy--
No SRM was submitted by Tetra Tech to determine the accuracy of 210-Pb
analysis. A transcription error was noted for two sampling intervals of a
single core sample and was corrected.
Calculation of Sediment Accumulation RatesSediment accumulation rates
were recalculated for a QC check. These accumulation rates (cm/yr) were
calculated by fitting a line to the relationship between sediment depth and
the natural logarithm of excess 210-Pb activity over the interval below the
mixed layer using the method of least squares. Accumulation in units of
g/cm2/yr were calculated by multiplying the accumulation in cm/yr by the
average dry density over the sediment interval to which calculations were
applied.
Several discrepancies in the calculations of sediment accumulation
rates were discovered, and these are shown in Table G-31. The correlation
coefficients reported for the least squares fit of the relationship between
excess 210-Pb activity and depth are unacceptable for several of the cores
(i.e., CW-92B, MI-91B, and SI-92B). The sedimentation rates so derived are
not reliable. The poor correlation is probably due to dredging or slumping,
which violates the assumptions in the 210-Pb calculation and renders the data

DATA QUALIFIERS
B = Value corrected for "blank" contributions; resulting value is less
than or equal to the required limit of detection for that compound.
C = Value for substance is included in the total for a defined
combination of unresolved substances.
E = Estimated value.
EU = Target compound was not detected in the sample at the estimated
detection limit shown. The detection limit accounts for the poor
recovery observed in matrix spikes samples.
G-38
-------
G = Estimated value is greater than the minimum shown based on matrix
spike results.
L = Value is less than the maximum shown.
M = Value shown is a mean of replicated measurements.
Q = Questionable data.
U = Substance undetected at the detection limit shown.
X = Isotope labeled standard recovery <10 percent, applied only to
detected compounds.
Z = Value corrected for "blank" contributions; resulting value is
greater than the required limit of detection for that compound.
MISSING VALUES
Unanalyzed samples, unreported data values, or data rejected during QA
review are shown as blanks in the tables.
a Sampling locations, sampling dates, sample collection methods, analytical
methods, and QA/QC are discussed in the text.
