EPA's Contaminated
Sediment Management Strategy Published
To address the ecological and human health risks that contaminated sediment
poses in many U.S. watersheds, the Agency has published EPA's Contaminated
Sediment Management Strategy. Also available for review, through the Office
of Water Docket (202 260-3027), is the Response to Public Comments Document.
The Strategy is an EPA workplan describing actions the Agency believes
are needed to bring about consideration and reduction of risks posed by
contaminated sediments. In it, EPA summarizes its understanding of the extent
and severity of sediment contamination, including uncertainties about the
dimension of the problem and describes the cross-program policy framework
in which EPA intends to promote consideration and reduction of ecological
and human health risks posed by sediment contamination.
The Strategy establishes four goals:
To control sources of sediment contamination and prevent increases
in the volume of contaminated sediment.
To reduce the volume of existing (in-place) contaminated sediment.
To ensure that sediment dredging and dredged material disposal are
managed in an environmentally sound manner.
To develop a range of scientifically sound sediment management tools
for use in pollution prevention, source control, remediation and dredged
material management.
EPA's Contaminated Sediment Management Strategy sets forth a plan to
accomplish a number of key actions.
Agency programs will use consistent and scientifically sound sediment
assessment methods in their prevention or remediation processes.
Agency programs will use the first National Sediment Quality Survey
Report to Congress (EPA 823-R-97-006) and future biennial updates to target
chemicals and watersheds for further assessment, pollution prevention,
and remediation.
Where watersheds are clean, EPA will prevent sediment contamination
through point and nonpoint source controls, promoting best management practices,
and by testing new pesticides and other chemicals to ensure that they will
not contaminate sediment.
Where watersheds are being contaminated, EPA will take appropriate
action through its point and nonpoint source control programs to reduce
or eliminate contaminant inputs.
Where watersheds are already contaminated, EPA will develop risk management
strategies and implement source controls.

Study
of Abyssal Seafloor Isolation of Contaminated Sediments Concluded
Recognizing the rapidly decreasing availability of disposal sites on
land, in 1993 Congress directed the Department of Defense to assess the
technical and scientific feasibility of isolating contaminated dredged material
on the abyssal seafloor. The Naval Research Laboratory (NRL) conducted and
managed the assessment, which was funded during its first year by the Strategic
Environmental Research and Development Program and in the following two
years by the Defense Advanced Research Projects Agency. NRL carried out
the projects in collaboration with participants from academic institutions
and industrial organizations.
The seafloor isolation concept is an attractive management option for
contaminated dredged material because, if abyssal isolation is feasible
and environmentally sound, air, land, or water supplies would not be contaminated.
The participants concluded that it is technically and environmentally feasible.
In ports where shipping costs are high, abyssal seafloor isolation is a
cost-competitive strategy. They also outlined the architecture of a system
to monitor conditions at the site and to detect and measure possible leaks
of contaminated material.
Suitable Disposal Site Found
Material should be placed in as few sites as possible, ideally only one,
to minimize the affected area. This is a major constraint. Introducing dredged
material, with its high organic content, into the abyssal environment can
be expected to alter the local geochemical and biological conditions for
hundreds and possibly thousands of years.
After extensive analysis of oceanographic, meteorologic, geologic, and economic
constraints, the project team identified a suitable area in the Hatteras
Abyssal Plain, about 1,600 km (992 mi.) south of Boston and 1,100 km (620
mi.) east of Jacksonville.
During its first year, the project determined that the optimal means
of transporting material to the site would be large bags made of synthetic
fabric that holds 400-800 cubic meters of material. Barges would haul the
containers from a dredging site to the ocean isolation site, where they
would be released to fall freely to the abyssal seafloor. Container walls
and seams would be strong enough not to tear during release from the barge
and the subsequent 5,000-meter descent and impact on the abyssal seafloor.
Only one probable pathway for contaminants to enter the productive surface
ecosystem was identified: the eggs of certain abyssal fish. However, the
quantity of transport would be negligible.
Monitoring System Designed
In the last year, the project has identified several types of sensors and
platforms that could be used to monitor the isolation site for possible
leakage. The monitoring system architecture was formulated to deploy, operate,
maintain, and retrieve data from the sensor suite. This was challenging
due to the levels of measurement sensitivity and the stability required
in the high pressures and low temperatures of the abyssal regions.

Regional Activities
EPA Great Lakes National Program Office Ottawa River, Ohio: Contaminated Sediment Remediation Project Completed
Concentrations of polychlorinated biphenyls (PCBs) in the sediment of
a former tributary to the Ottawa River in Toledo, Ohio are less than 10
parts per million (ppm) following completion of a $5 million remediation
project in May.
The project was the result of a partnership between the City of Toledo,
the Ohio Environmental Protection Agency (OEPA), the U.S. Environmental
Protection Agency, and GenCorp, Inc. To help "jump start" the
effort and demonstrate the effectiveness and efficiency of a partnership
approach to addressing sediment contamination, U.S. EPA's Great Lakes National
Program Office awarded a $500,000 grant to OEPA. An additional $140,000
came from an OEPA solid waste settlement with the City of Toledo, and approximately
$4,500,000 came from GenCorp.
Part of Maumee Area of Concern
The Ottawa River flows into Maumee Bay in Lake Erie's western Basin and
is part of the Maumee River Area of Concern. The remediated tributary is
975 feet long and 90 feet wide. It is located about five miles upstream
from Maumee Bay. PCB concentrations in the tributary had ranged up to 74,000
ppm, and fish found in the vicinity contained PCBs at concentrations over
500 ppm. A consumption advisory for eating fish taken from anywhere in the
Ottawa River, issued by the Ohio Department of Health, remains in effect.
The PCBs came from a variety of sources. The primary source was an industrial
facility bordering the tributary and formerly owned by GenCorp. The facility
used a heat exchange fluid that contained PCBs, and some of the PCB fluid
entered the tributary. Several landfills near the tributary are also suspected
sources of PCBs. Two are being remediated under the Superfund Accelerated
Cleanup Model.
Assessment and Clean Up
Prior to remediation, a comprehensive assessment and characterization program
delineated the boundaries of the PCB-contaminated sediment. Then, several
remedial options were investigated. The chosen option called for a sheet
pile coffer dam to isolate the tributary hydraulicly from the Ottawa River's
main stem. Once the dam was in place, water was pumped and treated on site,
and about 8,000 cubic yards of contaminated sediment were removed. The sediment
was transported to a Michigan landfill licensed under the Toxic Substances
Control Act. An estimated 56,000 pounds of PCBs were removed. The excavation
was conducted "in the dry" to minimize any potential impacts due
to resuspension of the highly contaminated sediments.
After the project was finished, the tributary was backfilled with 5 to
10 feet of clean clay, and a new swale was constructed about 100 yards to
the west. The former tributary was graded and reseeded with a native wetlands
seed mix. The remediation will have positive short- and long-term impacts
on the Ottawa River, Maumee Bay, and Lake Erie. The cleanup has removed
a major source of PCB contamination in the Ottawa River, and a significant
source of contamination to Maumee Bay and Lake Erie. Fish and sediments
in the Ottawa River will continue to be evaluated to monitor the reduction
of exposure as a result of these remedial efforts.

EPA Region 2 Program EvaluatesTechnologies to Treat Contaminated Sediments from New
York/New Jersey Harbor
More than 400 million cubic yards of sediments
are dredged from U.S. waterways each year, and close to 60 million cubic
yards are disposed of in the ocean. The need to protect the environment
from the undesirable effects of sediment dredging and disposal is gaining
increased attention from the public and government agencies.
The handling of contaminated sediments in the Port
of New York/New Jersey exemplifies this problem. Each year, between 4 million
and 7 million cubic yards of sediment must be dredged there to permit safe
navigation and commerce. That sediment contains contaminants that are among
the highest concentrations in the country. Heavy metals, chlorinated pesticides,
polynuclear aromatic hydrocarbons, polychlorinated biphenyls, and dioxins/furan
are the major contaminants of concern. Several contaminants detected in
the sediments and in fish and shellfish have resulted in fishing advisories.
A Team Approach
The Water Resources Development Act (WRDA) of 1992 (section 405C) and 1996
(section 226) mandated a demonstration of the feasibility of decontaminating
sediments from New York/New Jersey Harbor. As a result, a multicultural
team was formed. It included representatives of government, industry, academia,
and the general public. The WRDA Program is the responsibility of EPA Region
2 and the U.S. Army Corps of Engineer's New York District. The Department
of Energy's Brookhaven National Laboratory is the technical project manager.
The program has progressed through demonstrations
of various technologies at the bench and pilot scales and is now moving
toward the construction of commercial-scale facilities. This step-wise procedure
has reduced the number of participants through specific selection criteria,
including technical performance, demonstration costs, public-private cost
sharing, beneficial reuse of treated material, and corporate evaluations
of the business potential for sediment decontamination.
Federal funding available under WRDA provides assistance
to the commercialization process, but the private sector will provide the
capital needed for facility construction and operation. The program participants
believe this type of cooperative approach will be useful in the New York
and New Jersey region—and may have features of interest to other U.S.
ports that must dispose of contaminated sediments.
Dumping Options Dwindle
Stricter regulations have reduced the amount of dredged material considered
suitable for dumping in the coastal Atlantic Ocean, thus creating an operational
crisis for the New York/New Jersey Harbor. On September 29, 1997, EPA de-designated
and terminated the dredged material ocean disposal site and simultaneously
designed the Historic Area Remediation Site (HARS). The HARS can receive
only dredged material suitable for use as "Material for Remediation,"
defined as "uncontaminated dredged material (i.e., dredged material
that meets current Category I standards and will not cause significant undesirable
effects, including those caused by bioaccumulation)."
Current proposed solutions to the port's dredged
material disposal problem include:
Continued unrestricted ocean disposal of uncontaminated
material to the HARS.
The use of confined disposal facilities (both
upland facilities and containment islands).
Subaqueous borrow pits.
Processing/treatment of contaminated materials.
A complete solution to the dredging problem will
likely include a combination of many, or all, of these alternatives. Decontamination
is one component of the overall dredged material management strategy. It
can reduce the magnitude of the contamination, and may provide a treated
product that can be sold for reuse, thus simplifying disposal and possibly
reducing the overall cost of treatment.
Seeking Economic Alternatives
Goals of the WRDA Program include demonstrating sediment decontamination
technologies and creating a treatment train capable of annually processing
as much as 500,000 cubic yards of contaminated sediment. This treatment
train includes sediment assessment (3-D sediment visualization), dredging,
materials handling, decontamination and beneficial reuse of the post-treated
material.
Bench- and pilot-scale tests of various technologies
were completed in December 1996. The technologies included thermal destruction
and desorption processes, stabilization/solidification, sediment washing,
advanced chemical treatments, solvent extraction methods, and manufactured
soil production. The development of an overall conceptual plan for implementing
a large-scale facility is underway.
Various contaminants are present at a wide range
of concentrations in material dredged from the New York/New Jersey Harbor.
This fact necessitated the development of several types of decontamination
technologies to provide comprehensive treatment. In each case, the processed
materials have beneficial uses and can be sold to offset a portion of the
decontamination costs.
In 1998, the WRDA Program is focusing on a system
of low- to high-temperature technologies that can accommodate a range of
sediment contamination. These approaches include a sediment washing method
developed by BioGenesis Enterprises, Inc., a high-temperature process developed
by the Institute of Gas Technology (IGT) to destroy organic compounds and
bind metals into a cementitious matrix, and a Westinghouse plasma-arc vitrification
process. Work also is being done on manufactured soil production; the U.S.
Army Corp of Engineers Waterways Experiment Station is using untreated sediment
for that purpose, and BioGenesis is looking at using treated sediment from
the harbor.
Beneficial Uses
The material dredged from the New York/New Jersey Harbor consists mainly
of fine-grained silt and clay, and is unsuitable for use as structural fill
directly after treatment. Because treatment destroys naturally occurring
organic material as well as organic contaminants, the treated material typically
is not a useful growth substrate. However, the treated material can be mixed
with other material to make a variety of useful products, including potting
soil, top soil, and daily landfill cover. It also can be used in wetlands
and habitat restoration, and in the restoration or filling of underwater
areas.
The blended cement produced by the IGT high-temperature
Cement Lock™
Technology exceeds the American Society for Testing and Materials requirements
for portland cement. It can be used in concrete for general construction
applications.
Anticipated Commercial Operation
The large-scale treatment facilities that will meet the WRDA treatment goal
are expected to become operational in 12 to 30 months. But before they begin
operating, they must obtain state and local permits. The permit process
for sediment washing should be relatively straightforward, since there are
no gaseous sidestreams, and contaminants found in a liquid side stream can
be removed by standard water processing techniques. The high-temperature
process, however, will require comprehensive air permits.
Environmentally safe decontamination technologies
also must be economically viable. Currently, dredged material is stabilized
with fly ash and used for construction material and cover at several locations
in New Jersey. The total cost of dredging, stabilization, and disposal ranges
from $40 to $50 per cubic yard. Current disposal costs in the Newark Bay
confined disposal facility are about $35 per cubic yard.
WRDA Program managers are confident that costs
of sediment washing and cement production will be competitive—at or
below $35 per cubic yard—when full-scale operation is underway.

UC Berkeley Researchers
Use In Vitro Technique to Measure Bioavailability of Sediment-Associated
Contaminants
Researchers at the University of California at
Berkeley are using in vitro digestive fluid extraction to measure sediment-bound
contaminant bioavailability. The original description of the technique (Mayer
et al., 1997) and further development (Weston and Mayer, 1998a; 1998b) have
shown the approach provides a measure of the bioavailability of sediment
contaminants in a wide variety of risk assessment scenarios and can be used
to study the basic mechanisms of how organisms accumulate contaminants from
sediments.
When a deposit-feeding organism ingests sediment,
the chemistry of the gut environment determines if the associated contaminants
can be desorbed from the particles and are available for dietary absorption.
The researchers mimic this process in vitro, by incubating the sediments
of concern in digestive fluid and expressing bioavailability as the percentage
of contaminant solubilized in those fluids.
The approach presumes that the contaminant extractable
by digestive fluid is implicitly a far better indicator of the bioavailable
fraction than that extractable by the strong acids or exotic organic solvents
typically used in a chemical analysis. Chemical extraction methods are generally
designed to recover the total, rather than the bioavailable, contaminant.
Some proposed selective extractions (for example, a weak acid extraction
for trace metals) purport to quantify the bioavail-able fraction, but none
have been generally accepted or broadly adopted. The digestive fluid technique
is essentially a chemical extraction, but with a biologically relevant extractant.
Biological methods such as toxicity or bioaccumulation
testing are currently used widely to measure bioavailability, yet interpretation
of the results can be confounded by factors unrelated to bioavailability.
For example, toxicity can also be a function of the organism's prior acclimation
or adaptation. Bioaccumulation as a measure of bioavailability is confounded
by behaviors affecting exposure (such as feeding and respiration rates)
as well as metabolism of the contaminant of interest.
Results
Because of its large size and the amount of digestive fluid that can be
recovered, the polychaete Arenicola brasiliensis has been a source of digestive
fluid for most of the UC Berkeley researchers' work. They have used this
fluid to extract sediments from throughout California contaminated with
polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs),
or trace metals. Their results have included the following observations:
Gut fluid pH of a wide variety of invertebrates
is near neutral. That raises questions about the biological relevance of
the strong acid extractions used in traditional chemical analyses for metals.
Much of the contaminant extractable by traditional
chemical means is not extractable in digestive fluid. When six California
sediments were spiked with PAHs, only 12 to 50 percent of the PAHs were
solubilized in an in vitro digestive fluid extraction. Thus, any assessment
based on total PAHs would have overestimated the risk posed by these sediments
by a factor of two to eight.
In vitro contaminant extraction is similar to
that obtained in vivo. Allowing intact A. brasiliensis to feed on contaminated
sediments and then analyzing the PAH content of their gut fluids produced
very similar results to dissecting digestive fluid from unexposed A. brasiliensis
and doing the extractions in vitro.
Digestive fluid extraction gives results similar
to other traditional bioavaila-bility measures using whole animal exposures.
The extractability of PAH in digestive fluid
is highly dependent upon the organic carbon content of the sediment. Organic
carbon is widely recognized as an important determinant of bio-availability,
so it is encouraging that its influence is apparent in in vitro extractions
as well.
Extraction efficiency is concentration dependent.
The more contaminated a sediment is, the greater the proportion of contaminant
that is bioavailable. This result is not unexpected, but it has never been
tested by other bioavailability studies.
Extending the researchers' work to include species
representing several phyla clearly shows that bioavaila-bility is a concept
that depends upon the exposed species. The digestive fluid of some species
is capable of extracting an order-of-magnitude more contaminant from ingested
sediment than is the fluid from other species.
The approach can be used to test the effect of
sediment holding time or conditions (such as freezing) on the bioavailability
of sediment-bound contaminants. For example, when a sediment was spiked
with PAHs and immediately extracted by digestive fluid, 70 percent of the
PAHs was solubilized. Holding the sediment for three weeks cut the extractable
proportion to 35 percent. Sediment aging has been shown to decrease bioavailability
in a number of other bioaccumulation and microbial degradation studies
as well.
Potential Applications
The in vitro digestive fluid extraction technique provides an intuitively
attractive method to quantify contaminant bioavail-ability to aquatic organisms.
It has obvious utility in any application where quantification of the bioavailable,
rather than total, contaminant is desirable and when ingestion of contaminated
sediments is a potential route of contaminant bioaccumu-lation. The approach
has the ecological relevance of biologically based methods to measure bioavailability,
such as bioaccumulation testing, but without some of the complications such
as metabolism of the compound of interest.
Since the technique does not require exposure of
whole animals, sediments can be evaluated even when conditions are unsuitable
for long-term animal exposure (for example, anaerobic conditions or hypersaline
environments). The approach holds great promise in studying the fundamental
mechanisms of bioaccu-mulation, in establishing the effect of laboratory
manipulations of sediment on bioavailability, and in ecological risk assessment
of contaminated aquatic sediments.
