INTRODUCTION
1.1
INTRODUCTION AND PURPOSE
This Data Summary and Evaluation Report for the Sediment Coring Pilot Project for the Lower
Passaic River Restoration Project has been prepared by TAMS Consultants, Inc., an Earth Tech
Company (TAMS/ET), Malcolm Pirnie, Inc. (MPI), and Aqua Survey, Inc. (ASI) for the New
Jersey Department of Transportation – Office of Maritime Resources (NJDOT-OMR) as
authorized under NJDOT Agreement No. 2001-NJMR02 Task Order #OMR-03-6. The purpose
of this task, which as described in the Project Plans for Geophysical Surveys and Sediment
Coring (TAMS/ET and MPI, June 2004) was to conduct a Hydrographic Survey, Side Scan
Sonar Survey, and Sediment Coring in order to perform a detailed characterization of the Pilot
Study Area for the Environmental Dredging Demonstration and Sediment Decontamination
Technology Demonstration – Treatability Study. This work is part of the Lower Passaic River
Investigation and Feasibility Study, a joint effort of Federal and State Agencies to remediate and
restore the Lower Passaic River Basin. The purpose of the overall Feasibility Study is to develop
a comprehensive watershed-based plan for the remediation and restoration of the Lower Passaic
River. During this pilot-scale demonstration project, approximately 5,000 cubic yards of
contaminated sediment will be dredged from the Harrison Reach of the Passaic River. It is
anticipated that this dredging will be performed in September 2005. Concurrent with this
investigation, the Institute of Marine and Coastal Sciences at Rutgers University and the Water
Resources Division of the United States Geological Survey are collecting data to support the
hydrodynamic modeling for the Passaic River. After these data are evaluated, separate Project
Plans that describe the sampling, monitoring, and other activities to be conducted during the
dredging pilot study will be prepared by TAMS/ET and MPI. Hydrodynamic modeling in
support of the dredging pilot study is being conducted by TAMS/ET. A Dredging Technology
Review Report has been prepared by TAMS/ET and MPI (June 2004). Technical specifications
for the dredging contractor are also being prepared by TAMS/ET and MPI.
The objective of the dredging demonstration project is to study dredging productivity and
sediment resuspension for the Lower Passaic River. Evaluating the success of dredging requires
the collection of data to determine the resuspension production rate, the resuspension release
rate, and the resuspension export rate and to perform a mass balance. In addition, equipment
performance, dredging production rates, turbidity levels, and engineering controls will be
evaluated. The objective of the sediment decontamination technology demonstration project is
to show that Passaic River sediments, contaminated with dioxins, polychlorinated biphenyls
(PCBs), polycyclic aromatic hydrocarbons (PAHs), metals, pesticides, herbicides, and other
contaminants can be successfully treated to meet applicable criteria for the appropriate beneficial
use end product (e.g., cement, light weight aggregate, manufactured soil, glass, etc.). The
decontamination project will collect data to perform a contaminant mass balance and determine
the economic viability of the treatment process for commercial scale applications. The
decontamination technology vendors will prepare separate work plans that describe these efforts.

TAMS/ET March 2005
The hydrographic survey was conducted to develop a bathymetric map of the Passaic River bed
along a 1,000-foot stretch at the river centerline in the Harrison Reach between the Jackson
Street Bridge and the New Jersey Turnpike Bridge (hereinafter referred to as the Pilot Study
Survey Area). The side scan sonar survey was conducted to characterize the texture of the
sediments and to identify any debris in the Pilot Study Survey Area. The work area for these
surveys encompassed the entire river bottom to the mean low water mark (MLW) along each
shoreline. Based on the results from the hydrographic and side scan sonar surveys, TAMS/ET
and MPI identified a 1.5-acre work area (referred to as the Potential Dredging Area) for the
collection of sediment cores in conjunction with NJDOT-OMR, USEPA, and USACE.
The sediment coring was conducted to establish a representative chemical and geotechnical
characterization of the sediments in the upper four feet of the Passaic River bed in the Potential
Dredging Area. All of this information is being utilized to support the objectives of the
combined dredging and sediment decontamination demonstration project.
The data summarized in this report was generated in accordance with the Project Plans for
Geophysical Surveys and Sediment Coring, which included a Work Plan, a Quality Assurance
Project Plan (QAPP), and a health and safety plan (TAMS/ET and MPI, June 2004).
In furtherance of the objectives of the Feasibility Study, this report provides a summary of
conditions within the Passaic River that may affect implementation of the dredging pilot
program. A brief history of the River’s industrial past that has led to a highly contaminated
estuarine ecosystem is also included.
1.2
STUDY AREA AND BACKGROUND
The Passaic River drains a 935 square mile watershed located in northern New Jersey and
southern New York states (Figure 1-1). Downstream of Dundee Dam (Garfield, NJ) the Lower
Passaic River is a tidal estuary with a connection to New York Harbor via Newark Bay. All or
portions of 117 municipalities in eight New Jersey counties, and 15 municipalities in two New
York counties are located within the Passaic watershed (see Figure 1-2). The Lower Passaic
River is considered to be the 17-mile tidally influenced portion of the river from the mouth of the
confluence at Newark Bay up to the Dundee Dam. Due to historical contaminant releases, the
Lower Passaic River sediments are contaminated with dioxins, polychlorinated biphenyls
(PCBs), polycyclic aromatic hydrocarbons (PAHs), metals, pesticides and other contaminants.
The Harrison Reach of the river was selected as the location for the dredging pilot. The rationale
for the selection of this location was presented in the Work Plan and is not repeated here.
Lower Passaic River sediments are contaminated with a variety of hazardous and toxic
substances including dioxin, PCBs, pesticides, total extractable petroleum hydrocarbons (TEPH),
PAHs, and metals. As a result of the presence of these contaminants in River sediments, the New
Jersey Department of Environmental Protection (NJDEP) has instituted a ‘do not eat’
advisory/prohibition for both fish and shellfish that inhabit the Passaic.
The Harrison Reach (Site) of the Lower Passaic River is the general study area for the pilot-scale
dredging program being planned for September 2005. Sediments within the Harrison Reach are
1-2
TAMS/ET March 2005
among the most severely contaminated and several of the principal sources of contaminants to
the river also are/were situated here. This reach has become a particular focal point for the pilot
program since it provides an opportunity to handle and process the widest range of contaminated
sediments and, therefore, the results obtained from the pilot program can be expected to have the
broadest applicability to ultimate remediation of the river system.
The Harrison Reach extends approximately two miles from the NJ Turnpike Bridge to the
Jackson Street Bridge that connects Harrison with Newark. The Study Area is bordered to the
north by the City of Harrison in Hudson County and to the south by the City of Newark in Essex
County (Figure 1-3). The Passaic River is aligned in a nearly true east-west direction in the
central portion of the Harrison reach. Upstream and downstream of this central area the River
exhibits a series of bends. To simplify evaluation and monitoring of dredging operations, the
proposed demonstration project is expected to occur in the portion of the Harrison Reach that is
aligned east-west.
According to the RI/FS Work Plan submitted to the USEPA in 1995 (USEPA, 1995), the
Harrison reach also contains a total of six direct and three indirect combined sewer overflow
(CSO) discharges into the Passaic River. Five of the direct CSOs are along the southern bank.
The three indirect CSO discharges are located on Franks Creek, a small creek that enters the
Reach from the northern bank approximately midway through the Site.
The USACE had historically designated a 300-foot wide navigation channel within the Harrison
Reach with a Project Depth of 20 feet MLW. Based on a hydrographic survey conducted by
USACE in 1989, water depths in the Reach ranged from 21.1 feet at mean low water (MLW) at
the downstream end of the Reach to approximately 19.2 feet (MLW) at the upstream end.
However, a more recent USACE channel condition report (2002) noted significant shoaling.
According to the Work Plan for the RI/FS submitted to the USEPA in 1995, the only dredging
event in the Harrison Reach within the period of interest (1940 to 1995) was performed in 1949
to the Project Depth of 20 feet. Sediment surface cross sections within the Pilot Study Survey
Area generated by TAMS/ET from the current investigation are provided in this report.

SEDIMENT CORING AND SAMPLING
The field sampling activities were conducted to characterize sediments in the Potential Dredging
Area (Figure 2-1) for the Environmental Dredging Demonstration and Sediment
Decontamination Technology Demonstration – Treatability Study. The pilot study is part of the
Lower Passaic River Restoration Study, a joint effort of Federal and State agencies to restore the
Lower Passaic River Basin. The objective of the study is to develop a comprehensive, watershedbased plan for the remediation and restoration of the Lower Passaic River, shown in Figure 1-2.
The Potential Dredging Area, where the sediment sampling was conducted, is located in the
Harrison Reach area of the Lower Passaic River (Figure 2-1). This reach was selected based on
several factors, including the river configuration, volume of contaminated sediments, access
characteristics, and river velocity. The selected reach is also relatively light in river traffic, which
will allow work to be completed unhindered.
Sediment core sampling was conducted using vibratory coring techniques. The work was
performed from July 12 through July 14, 2004. Personnel from ASI advanced and retrieved the
core samples, with oversight from NJDOT-OMR and MPI. Core processing and sediment sample
management activities were performed by MPI and TAMS/ET, with assistance from NJDOTOMR and EPA.
Docking and river access was provided by Passaic Valley Sewage Commission (PVSC), and
transport and sampling vessels were provided by PVSC and ASI. PVSC personnel escorted
personnel from a security checkpoint to and from their dock at the beginning and end of each
day. The Robert E. Hayes, an ASI lift barge vessel, served as the base of operations for the field
activities. For the first two days of sampling, the Robert E. Hayes was stationed downriver east
of the NJ Turnpike Bridge and the Point-No-Point Conrail Bridge, and left in place overnight.
On the third day, the Robert E. Hayes was moved back to the PVSC facility and docked during
field operations.
Weather conditions during the field activities ranged from rainy and windy to hot and sunny. On
July 12, 2004, the weather conditions consisted of heavy rain and moderate wind in the morning,
with both lightening up in the afternoon and evening. On July 13, 2004, conditions were
uniformly cloudy throughout the day and evening with light rain and wind. On July 14, 2004,
conditions were very sunny and warm though the morning (77º F and climbing at 1000 hours)
and the early afternoon, with cooler temperatures, thunderstorms, and high winds moving in
during the afternoon.
2.1
HEALTH AND SAFETY PROCEDURES
Health and safety procedures required for core collection and processing, including personal
protective equipment (PPE) and air monitoring, were defined in the Project Plans for
Geophysical Surveys and Sediment Coring (TAMS/ET and MPI, 2004). Implementation of the
procedures is summarized below.
2- 1
TAMS/ET March 2005
2.1.1
Sampling Activities
Personal Protective Equipment (PPE) required for the subcontractor personnel aboard the ASI
coring vessel consisted of:
•
•
•
•
•
•
Tyvek suit or waterproof, washable gear (e.g., rain gear)
Nitrile gloves
Personal flotation device (PFD)
Steel-toe boots
Hard hat
Safety glasses
The MPI scientist conducting oversight on the ASI coring vessel used Level D protection (above
equipment less Tyvek coveralls), since oversight was conducted without handling the actual
cores. No air monitoring was conducted aboard the sampling vessel since only closed core tubes
were retrieved and handled (exposed sediment in the work area was limited to residuals clinging
to the outside of the retrieved core barrel).
2.1.2
Processing Activities
PPE employed by MPI and TAMS/ET personnel segmenting cores consisted of:
•
•
•
•
•
•
Tyvek suit and/or rain gear
Hard hat w/face shield
Heavy duty rubber outer gloves
Nitrile inner gloves
Steel-toe rubber boots
PFD
Core segmentation staff changed Tyvek suits if they became too wet or soiled. PPE employed
by MPI and TAMS/ET personnel performing core section classification, sample homogenization,
and sample management included:
•
•
•
•
•
Tyvek suit
Steel toe rubber boots or steel-toe boots with boot covers
Nitrile gloves (double layer)
Safety glasses
PFD
Staff conducting decontamination of sampling and processing equipment used the same PPE as
those performing core section homogenization and classification.
Air monitoring was conducted in the field using a HNU Systems PI-101 Photoionization
Detector (PID), MiniRae PID, and a Jerome Mercury Vapor Analyzer. Table 2-1 provides
information on air monitoring instrument daily calibration and results. The function of the HNU
2- 2
TAMS/ET March 2005
PIDs was compromised by high humidity during the intermittent to heavy rains on July 12 and
13; therefore, the Site Safety Officer (SSHO) requested a replacement instrument (MiniRAE
PID) less sensitive to humidity. The MiniRAE was transported to PVSC by MPI personnel and
delivered to the Robert E. Hayes by the crew of the PVSC vessel.
On the morning of July 14, when ambient temperatures rose above 70º F, the SSO initiated heat
stress monitoring of field personnel wearing Tyvek coveralls. Measurements were collected
approximately hourly using a digital thermometer (oral measurements). The SSO requested
specific staff to take a rest break/drink fluids if oral temperature increases were detected. The
SSO also decided, based on the proximity of the Robert E. Hayes to the PVSC dock on July 14,
to not require core processing personnel to wear PFDs under their Tyvek suits to alleviate heat
stress (the MPI Corporate Health and Safety Manager was consulted and concurred). A large tarp
was also raised using the crane of the vessel to shield personnel from the sun.
2.2
SAMPLE COLLECTION
The procedures for core collection were defined in the Project Plans (TAMS/ET and MPI, 2004).
Core collection was performed by ASI personnel, with oversight from MPI staff. Sampling was
originally to be conducted using a single ASI core sampling vessel (pontoon boat), but engine
failure experienced early on July 12 required the pontoon boat to be tied to another vessel for
propulsion. The core vessel engine failure resulted in a delay in the initiation of sampling
activities until mid-afternoon on July 12 (pending arrival of the second vessel). Because of rain
during sampling activities, the computer and DGPS equipment (other than the antenna) were
kept in the sheltered area of the “propulsion” vessel. The antenna was also located on the
propulsion vessel, as close as practicable to the vibracore apparatus.
Oversight log forms were filled out for each core collected. The log forms include the actual
sampling coordinates, sample number, water depth, tide stage, approximate sediment description,
time of core collection, time of vibracore initialization, penetration depth, recovery, and other
pertinent observations (including weather) for each core/location. Copies of the log forms are
included in Appendix A.
2.2.1 Procedure
The sampling vessel was equipped with a global positioning system accurate to 1 meter or less
horizontally. Data were reported in horizontal datum NAD 83 and NJ State Plane coordinate
system, and national geodetic vertical datum (NGVD) 1929. See Table 2-2 for the target
coordinates of each sampling area. The target accuracy for coring location measurements was as
follows:
•
•
•
•
Depth of water: ± 0.5 feet
Horizontal position: ± 3 feet
Depth of sediment penetration: ± 2.5 cm
Depth within the sediment core: ± 1 cm
2- 3
TAMS/ET March 2005
Achievement of a horizontal position within three feet of the target was extremely difficult for
several reasons. The windy conditions and attachment of the sampling vessel to the propulsion
vessel made maneuvering, positioning, and stabilization of the sampling vessel difficult. In
addition, the DGPS antenna was located on the propulsion vessel, adding another challenge to
achieving an actual horizontal position within thee feet of the target location. The majority of the
cores were collected within a recorded horizontal distance of ten feet from the target.
Location was confirmed through examination of the site map, bathymetric survey, and
landmarks. At the time of sampling, locations were recorded to an anticipated accuracy of about
± 1 cm using RTK DGPS. The DGPS antenna was mounted as close to the vibracore apparatus
as the connection cable would allow. See Table 2-3 for the final coordinates and offset
information.
A clean, decontaminated, clear plastic coring tube liner and core catcher were mounted within a
clean core barrel on the vibracore apparatus, as per the manufacturer’s directions. Care was taken
to seat the tube properly in the vibracore head, and that the check valve had a tight seal. The liner
and the barrel were 8 feet in length.
The vibracore unit was then lowered until the bottom of the core barrel reached the river bottom
and engaged. The tube was advanced through the sediment until refusal, or to the maximum
penetration allowed by the 8-foot length of the core barrel. The vibracore unit was then
disengaged and extracted from the bottom slowly by the lift cable, keeping it in a vertical
orientation. Penetration depth was confirmed by visually inspecting the core barrel for a mud
line.
Excess sediment was washed off the core barrel as the tube was raised out of the water, after the
mud line was observed. When the bottom of the core was within reach, a safety hook and line
were attached to the core catcher, and the core liner was removed from the core barrel.
The bottom of the core catcher was capped, and both the cap and core catcher were taped to the
plastic tube after the core had been brought on board and the rivets removed to free the core
catcher assembly from the core barrel. The top of the core was then capped, taped, and the core
tube lashed to the railing of the propulsion vessel for transport to the Robert E. Hayes, while
maintaining the retrieved core in a vertical orientation. The core was then examined for gaps, and
the recovery was measured. Recovery measurements are included in the coring logs provided in
Appendix A.
The recovery was determined by measuring the distance from the bottom of the core to the
sediment-water interface (“mud-line”) inside the tube. The core catcher length (approximately 2
inches) was included in the core recovery value. If at least 36 inches of material was collected,
and the core recovery was 60 percent or greater, the core was retained for processing.
If less than 36 inches of material was recovered, the recovery was less than 60 percent, or gaps
greater than 2 inches were present in the core, the core was considered unusable and another
attempt made within 3 to 5 feet from the initial location. Excess sediments from cores with
unacceptable recovery were collected using a 5-gallon bucket.
2- 4
TAMS/ET March 2005
Cores were brought to the Robert E. Hayes for processing in groups of three or four, and custody
was relinquished to the processing crews. All cores were kept vertical from the time of collection
through segmentation.
2.2.2
Locations and Location Design
The sampling area (Potential Dredging Area) was defined as a rectangle 100 yards long by 75
yards wide. The area was divided into 15 rectangular sampling cells, each 20 yards long by 25
yards wide. The 15 sampling cells were organized into five transects (A through E) with three
samples in each transect. See Figure 2-1 for a schematic representation of the sampling grid. One
sediment core was collected within each grid cell.
2.2.3
Summary of Samples Collected
A total of 17 cores were collected for processing on the Robert E. Hayes: 15 original samples
and two duplicate cores. Two cores were provided to Montclair State University (Monclair, NJ)
researchers. One original sample core (B3) was re-collected when the first core was lost
overboard during transfer to the processing area.
2.3
SAMPLE PROCESSING
The procedures and requirements for sample processing were defined in the Project Plans
(TAMS/ET and MPI, 2004), with the exception of those defined for composite sample
collection.
Core processing activities were performed on the deck of the Robert E. Hayes. Personnel from
MPI cut the cores into 1-foot long segments, and personnel from TAMS/ET, MPI, and the
NJDOT-OMR prepared sample jars, described, processed, and packed the samples for delivery
to the laboratory. Sediment samples were collected and submitted for the following analyses:
•
•
•
•
•
•
•
•
•
•
•
•
PCBs (aroclors and congeners)

2.3.1 Core Processing Procedure
After being relinquished by the ASI sampling personnel, cores were staged by lashing them
vertically to the rail of the Robert E. Hayes. Sediments suspended in the water at the top of each
core tube were allowed to settle prior to processing. Once the majority of the fines had settled,
the stratigraphy was described and recorded by field personnel, making note of any separations.
The top cap was removed from the core, and the location of the sediment/water interface within
the core tube was verified using a decontaminated probe inserted into the core. Excess water
was then drained out through a hole drilled an inch or two above the water/sediment interface,
taking care to minimize the loss of or disturbance to the sediment/nepheloid layer (the particlerich layer at the sediment-water interface). The excess tubing was also removed using a
reciprocating saw. The core tube and sediment recovery were then measured, and the core was
weighed.
The segmentation scheme for the cores consisted of cutting each core into 1-foot segments. The
1-foot intervals were measured and marked on the outside of the prior to beginning cutting.
Sectioning began at the top of the core. A reciprocating saw was used to cut through the core
tubing, and a decontaminated, stainless steel plate was pushed through behind the saw blade to
separate and lift the core section from the rest of the core.
On July 13, core collection outpaced core processing activities. Cores C1, D1, D2, and D3 were
not segmented at the end of the work day. To preserve the core samples overnight, each of the
cores was cut into 0-36 inch and 36-end depth segments, capped and taped, labeled with core ID,
depths, and orientation information (permanent marker on the plastic core tube and caps), and
stored in “core coolers” filled with cube ice. Approximately one inch of sediment was lost from
C1 and D1 during sectioning, when the bottom cap had to be placed on the 0-36 inch segment.
Loss of sediment was minimized from D2 and D3 by using the handle of a decontaminated
spoon to assist in attaching the bottom cap quickly. On the following morning (July 14), it was
observed that 0.25 to 0.5 inches of settlement had occurred in the 0-36 inch segments, measuring
from markings placed on the side of the core tubes after they were placed in the core cooler the
previous night. Specific data on each core’s settlement and segment length was provided to the
processing crew by the personnel responsible for segmentation.
The section was then transferred to a (tared) stainless steel bowl, with the sediments still within
the length of plastic tubing, and weighed. The bulk density data calculated from these field
measurements are shown on Table 2-4. Once weighed, the sediment was extruded into a stainless
steel bowl, and a description of the physical characteristics was recorded in the field notes.
Sediment texture was identified using the Burmeister classification system, and segments were
examined for changes in characteristics as the core was extruded from the tubing. Any changes
in characteristics and the approximate lengths of the different strata were recorded in the field
notes.
Once extruded, three EnCore samples were taken from the un-homogenized sediment, from three
separate areas of the section, to obtain a representative sample for volatile organic compound
(VOC) analysis. The section was then homogenized and subsampled into laboratory containers
for the other analyses required. The 0-1 foot,1-2 foot and 2-3 foot sections were sampled for
2- 6
TAMS/ET March 2005
immediate analysis, while the 3-4 foot core section was subsampled and archived for possible
future analysis. The archived samples were shipped to the analytical laboratories, with
instructions to freeze the samples. The archived samples were subsequently analyzed.
Composite samples were also created for each transect (A through E) sampled. One subsample
was collected from the 0-1 foot, 1-2 foot and 2-3 foot horizon in each of the three cores in a
transect (e.g., A1, A2, and A3). The three subsamples from each depth were combined and
homogenized to create a composite sample representing that particular depth horizon and
transect. The composite was created using an equal mass of sediment from each core. The total
subsample/composite sample weight was selected based in the amount of sediment required for
the laboratory analyses.
The bottom two inches of the 3-4 foot sample were discarded from all cores.
2.3.2
Decontamination Procedure
The decontamination procedure for non-dedicated equipment consisted of the following steps:
• Rinse with river water to remove excess mud and particulates
• Scrub surface of equipment with laboratory detergent
• Rinse with potable water
• Rinse with deionized water
Decontamination was performed on all non-dedicated equipment, including bowls, spoons, core
catchers, saw blades, and metal plates. Core catchers were wrapped in aluminum foil after
decontamination was complete pending use in core collection activities the next day. (Core
catchers were decontaminated on the larger boat, the Robert E. Hayes; as a result, the coring logs
[Appendix A], which were prepared on the smaller boat, have the note ‘No Boat Decon.’ In a
few cases, the aluminum foil in which the core catchers were wrapped was damaged, and the
core catchers were decontaminated again.) New (dedicated) core tube liner sections were not
decontaminated prior to use but were decontaminated after use, prior to disposal as solid waste.
2.3.3
Sample Handling and Transport
Sample jars were labeled with the sample ID, the date collected, the time collected, and the
analyses required. The label was then covered with clear, acetate tape.
Once the sample jars were filled, signed custody seals (at least one) were applied to each jar
across the neck so any tampering would be apparent. Custody seals were not placed on the
EnCore samples. The samples were sealed in the pouch provided with the sampling unit. The
sample jars and EnCore sample pouches were then placed in re-sealable food storage bags, and
placed in coolers with ice for transport to the analytical laboratory. Sufficient ice was used to
main a temperature of 4oC, ±2oC during transport. Custody seals were also applied to the coolers.
Samples were sent to three laboratories participating in the U.S. Environmental Protection
Agency Contract Laboratory Program (EPA CLP). Shipping documentation was prepared in
accordance with EPA CLP requirements. Samples were also sent to the USEPA Region 2 DESA
2- 7
TAMS/ET March 2005
laboratory in Edison, NJ, and to the STL-Knoxville, TN and STL-Burlington, VT laboratories.
Shipping documentation for transport to the DESA laboratory was prepared in accordance with
CLP requirements, with the exception that RSCC/SMO reporting was not required. Shipping
documentation for samples sent to STL laboratories included a Chain of Custody form rather
than the Forms II Lite documentation required by the CLP program.
Although it was intended to ship samples on the day of collection, the logistics of the project
(such as the time at which the core samples arrived on shore, and the time necessary to process
the cores into samples for shipment), the samples were generally shipped to the laboratories on
the morning after the cores were collected. Samples collected on the first day (July 12) were not
shipped until July 14; however, the samples were maintained under custody and on ice in coolers
prior to shipment.
2.4
DEVIATIONS FROM APPROVED PROJECT PLANS
Sampling activities were conducted based on site-specific Project Plans (TAMS/ET and MPI,
2004). Deviations from the Project Plans are summarized below.
2.4.1
Quality Assurance Project Plan
2.4.1.1 Core Collection
The majority of the core collection steps were conducted in accordance with the procedures set
forth in the Project Plans. One deviation was associated with the capping step. The cores were
not capped below the water’s surface upon retrieval, as defined by the procedure. The use of core
catcher and nose cone, which was riveted to the core barrel, prevented capping of the core tube
below the water’s surface. A safety line was attached to the bottom of the core catcher, and the
catcher was held in place via upward force on the safety line by one sampler while the rivets
were removed the rivets and the bottom of the core capped.
A second deviation from the defined procedure was associated with measurement of the core
recovery. The recovery was not measured by insertion of a decontaminated yardstick into the top
of the tube and resting on the sediment (performed later aboard the Robert E. Hayes). Instead,
recovery was determined by visually locating the sediment-water interface and measuring from
the bottom of the cap to the observed interface.
2.4.1.2 Core Processing
The core processing activities were conducted in general accordance with the requirements set
forth in the Project Plans. The only deviations observed was associated with the decontamination
procedure. Although the QAPP stated that all sampling equipment would be decontaminated
prior to use, the dedicated, single-use core liners were not decontaminated prior to use, as the
liners were new and clean as received. (The core liners were decontaminated after use, prior to
disposal as solid waste.) Also, the decontamination procedure in the QAPP specified that an
acetone rinse would be performed on stainless steel equipment used in core processing. The
decontamination activities performed in the field did not include an acetone rinse. Sample
2- 8
TAMS/ET March 2005
processing equipment was washed with alconox and then rinsed with river and tap water and
then given a final rinse with DI water.
2.4.1.3 Sample Shipment
Although it was intended to ship samples on the day of collection, the logistics of the project
(such as the time at which the core samples arrived on shore, and the time necessary to process
the cores into samples for shipment), the samples were generally shipped to the laboratories on
the morning after the cores were collected. Samples collected on the first day (July 12) were not
shipped until July 14; however, the samples were maintained under custody and on ice in coolers
prior to shipment.
2.4.2
Health and Safety Plan
2.4.2.1 Core Collection
The core collection activities were conducted in general accordance with the requirements set
forth in the site-specific HASP.
2.4.2.2 Core Processing
The majority of core processing activities were conducted in accordance with the requirements
set forth in the site-specific HASP. The only deviations were the result of decisions made on-site
by the SSO based on the weather conditions.
The first deviation from the HASP was associated with personnel monitoring. The HASP
governing the project included a requirement for cold stress monitoring. The field activities
were conducted in July 2004, and the ambient temperature did not fall into a range that required
cold stress monitoring. However, high temperatures for part of the day on July 14 indicated
potential concern for heat stress. The SSO monitored for heat stress during the time when the
temperature was a concern, a procedure that was not outlined in the plan.
The SSO also decided that due to the potential for heat stress, the processing personnel did not
need wear a PFD under the full Tyvek suit, in an effort encourage cooling of the body. The
decision also took into account the location and layout of the processing area, and the proximity
of the boat to the PVSC dock on that day.

GEOPHYSICAL SURVEYS
The geophysical surveys were performed under subcontract to TAMS/ET by ASI in the Pilot
Study Survey Area of Lower Passaic River within the Harrison Reach. These surveys included a
hydrographic survey, a side-scan survey, a magnetometer survey and a sub-bottom profiling
survey. The hydrographic and the side–scan surveys were conducted in March 2004, and the
magnetometer and the sub-bottom profiling surveys were conducted in November 2004 using the
RV Delaware, a 21-foot survey vessel. The vessel was equipped with a real-time kinetic (RTK)
system for positioning. Hypack Max survey management software was used for survey control
and ship track recording. An Innerspace Model 455 survey grade fathometer was used to collect
the water depth data. The RTK system used was a Trimble 5700. Detailed geophysical survey
reports, including equipment specifications as well as the data generated by the surveys, are
provided in Appendix B. A brief description of the geophysical surveys is given in this section of
the Data Summary and Evaluation Report. The geophysical surveys were conducted along a
1,000 feet stretch in the Harrison Reach between the Jackson Street Bridge and the New Jersey
Turnpike Bridge. This 1,000-ft bank-to-bank area is designated as the Pilot Study Survey Area.
The results of the bathymetric and side scan surveys were used to define the potential Dredging
Area (a smaller area of about 225 feet by 300 feet, approximately 1.5 acres) for sediment core
collection.
Sub-bottom profiling and magnetometer surveys were conducted in November 2004 in an
attempt to identify objects buried beneath the surface of the sediment that may pose hazards to
the dredging operation in the proposed Pilot Study Survey Area. The decision to conduct these
surveys was made after the Project Plans (TAMS/ET and MPI, 2004) had been implemented.
The magnetometer survey revealed 12 distinct magnetic anomalies as well as significant levels
of background geologic interference. Of the 12 targets identified by the magnetometer survey,
only two could be correlated with reflections in the sub-bottom profiles. In addition to these two
targets, two potential targets, not detected in the magnetometer survey, were detected by the subbottom profiler. Images of the magnetic signatures as well as the four targets observed on the
sub-bottom profiles are shown in Appendix B. None of the targets located were found to have
signatures indicative of historically significant submerged cultural resources. Because all of the
materials generating the targets are buried below the surface of the sediment, it is impossible to
positively identify them using remote sensing equipment. Whether the targets identified are a
concern for the future dredging operations cannot be determined. Should the potential exist for
the dredging equipment to be damaged by the targets, further investigation may be necessary to
determine the nature and depth of burial of the material generating the anomaly. This could be
accomplished using jet probing to delineate the size and shape of the object as well as its depth
of burial.
3.1
HYDROGRAPHIC SURVEY
The hydrographic survey encompassed the entire river bottom to the mean low water (MLW)
line along each shoreline. The survey work area extended for 1000 feet along the river from bank
to bank. The survey was conducted using 25-foot lanes and single beam acoustical survey
3-1
TAMS/ET March 2005
techniques to acquire depth soundings. Horizontal position of the depth soundings was obtained
using a differential global positioning system (DGPS) with RTK correction applied to the data.
The survey was conducted in horizontal datum NAD 83 and NJ State Plane feet and vertical
datum NGVD 1929.
The survey drawings show shoreline features in the vicinity of the site that were available on
NJDOT geo-referenced base maps. The geo-referenced shoreline features are shown for 1000
feet along the riverbank. The features shown are limited to the horizontal position of the furthest
riverward project of bulkhead walls and piers and the horizontal position of the highest elevation
of earthen/rip-rap slopes.
For the Pilot Study Survey Area, TAMS/ET used the data from the March 2004 surveys and
compared it with data from previous hydrographic surveys conducted by Tierra Solutions Inc.
(TSI) in March/April 1995, November 1996, May 1997, June 1999, and August 2001.
Figure 3-1 is a plane view of eleven transects across the width of the river in the Pilot Study
Survey Area. On this figure, Transect 5 passes through sampling grid cells A1, A2, and A3.
Transect 6 intersects sampling grid cells C1, C2, and C3 and Transect 7 intersects sampling grid
cells E1, E2, and E3. Figures 3-2 through 3-12 show sediment surface cross sections for each of
the eleven transects. Sediment surface profiles for the March 2004 survey are compared with
previous surveys conducted by TSI on these eleven figures. Figures 3-13 through 3-18 present
plan views of the bathymetry in the Pilot Study Survey Area for each of the hydrographic
surveys identified above.
3.2
SIDE SCAN SURVEY
A side-scan survey was conducted in the same 1000-foot section of the river where the
hydrographic survey was performed. This survey was conducted using a Marine Sonic System
running at 600 KHz frequency. RTK was used for positioning and Hypack Max survey
management software was used for survey control and ship track recording. This survey was
conducted by running lines parallel to the shoreline spaced 50-feet apart. Thirteen lines were run
resulting in greater than 150% coverage.
A mosaic of the riverbed in the study area was created, accompanied by annotation of individual
objects in a target file. All of the individual survey maps were plotted on Mylar and presented
on the same scale to enable them to be combined using overlays. This enables the data to be
layered together forming a composite picture of the project area. The sonar mosaic was plotted
on bright white paper, as the image was nearly opaque and lost significant details when plotted
on Mylar.
As part of the side-scan sonar survey, sediment samples at 30 locations were to be selected from
the top 2 inches for ground-truth purposes to help characterize the side-scan sonar results.
However, samples were collected at only seven locations and a field geologist classified the
sediment samples. The sampling locations were selected in the field, based on the side-scan
sonar images and the need to verify signal/sediment types.

TAMS/ET March 2005
3.3
MAGNETOMETER SURVEY
3.3.1
Magnetometer Data Collection
A magnetometer survey was conducted in order to detect the presence of buried ferrous debris
not detected during the side-scan sonar survey. The magnetometer survey also complemented
and aided in the interpretation of the side-scan sonar survey results, gathered from a survey in the
spring of 2004, regarding debris and potentially significant historic submerged cultural
resources. The survey methodology was designed to provide data indicating the position, and
relative size of ferrous targets in the survey area, as well as archaeological data essential for
complying with the National Historic Preservation Act of 1966, as amended, through 1992 (36
CFR 800, Protection of Historic Properties) and the Abandoned Shipwreck Act of 1987
(Abandoned Shipwreck Act Guidelines, National Park Service, Federal Register, Vol. 55, No. 3,
December 4, 1990, pages 50116-50145).
A Geometrics G-882 marine cesium magnetometer system magnetometer capable of ± 0.01
gamma resolution was be used to conduct the survey. Survey lines were run at 25-foot intervals
to provide complete coverage of the survey area. Data was recorded at 0.5 second intervals and
electronically paired with positioning data from a real-time kinematic global positioning system
using an onboard computer running Hypack Max 4.3 survey software.
Analysis of the magnetic data was initially carried out as it is generated to provide reliable target
identification and assessment. Significant magnetic anomalies were marked as targets during the
survey and were re-surveyed using the magnetometer to better determine the size and
characteristics of the anomaly.
Post-processing of the data involved examining each survey line individually and annotating
anomalies detected. Using contouring software, magnetic data generated during the survey was
contour plotted at 10 gamma intervals for analysis and accurate location of the material
generating each magnetic anomaly as well as determining the presence of clusters of targets.
Magnetic targets were isolated and analyzed in accordance with intensity, duration, aerial extent
and signature characteristics.
Data generated by the remote sensing equipment was used to support an assessment of each
magnetic signature. Analysis of each target signature included consideration of magnetic
characteristics previously demonstrated to be reliable indicators of historically significant
submerged cultural resources. Assessment of each target includes recommendations for
additional investigation to determine the exact nature of the cultural material generating the
signature and its potential National Register significance. All targets are listed and described and
a map has been produced that shows their location within the project area (see Appendix B)
3.3.2
Magnetometer Results
A Geometrics G-882 marine cesium magnetometer system was used for the magnetometer
survey. During the survey, the sensor was towed at a depth of 1 to 5 feet and approximately 40
3-3
TAMS/ET March 2005
feet behind the survey vessel to ensure the sensor was not detecting the vessel itself. The
magnetometer survey revealed 12 distinct magnetic anomalies as well as significant levels of
background geologic interference. The location of each of the magnetic anomalies was checked
on the side-scan sonar mosaic and no targets were duplicated in the two surveys. A detailed
description of each magnetic signature is given in Appendix B.
3.4
SUB-BOTTOM PROFILER SURVEY
3.4.1
Sub-Bottom Profiler Data Collection
An Edgetech X-STAR sonar system with a SB-216S towfish was used to collect the chirp subbottom profiling data during a survey along the Harrison Reach of the Passaic River. The
principal objective of the survey was to collect chirp images along lines that had been previously
surveyed with a magnetometer.
Chirp profilers use acoustic methods to generate high-resolution (on the order of 0.5-1 ft) crosssectional images of the marine sub-bottom to depths of up to 100 ft beneath the seafloor. These
profilers transmit a wide band FM sound pulse that is linearly swept over a full spectrum
frequency range (i.e., a “chirp”). The transmitted sound pulses travel through the water column
and sub-bottom and are reflected when changes in acoustic impedance (equivalent to a material’s
sonic velocity times its density) are encountered. Acoustic impedance changes commonly occur
at boundaries between materials (e.g., interfaces between water and sediments, sediments and
gas, and sediments and buried objects). The reflected sound pulses travel back to the profiler
where their amplitudes, as a function of travel-time, are digitally recorded.
During the survey, the SB-216S was towed at a depth between 3 and 6 ft. It was towed
approximately 6 ft aft of the navigational antenna on the port side of the ASI vessel R/V
Delaware. The SB-216S emitted a chirp sound pulse with a frequency range of 2-15 kHz, eight
times per second. Given this sampling interval with an average speed of 1 to 2 knots, the
horizontal spacing between individual pulses displayed on the chirp profiles was on the order of
0.2-0.5 ft.
Geographic position (i.e., latitude and longitude) along the chirp profiles was determined with
Trimble RTK Positioning System (Model # 5700). The data from the RTK were also used by the
HYPACK helm guidance and position recording software. These navigational data were logged
at one-second intervals by HYPACK and the X-STAR digital recording system
To correct the navigational data to the position of the SB-216S, its layback (distance aft of the
navigational antenna) was estimated during the survey while at the average towing speed of 1-2
knots. This distance of about 6 ft was used to correct the SB-216S position relative to the
navigation data. The navigational data for the targets identified in the earlier magnetometer
survey and their corresponding positions along the chirp profiles are presented in tabular form in
Appendix B along with one potential target identified in the chirp data that was not associated
with a magnetic anomaly. Along the chirp profiles, the position of the magnetometer targets were
identified as either the closest profile position to the target (i.e., in the case that the target was not
associated with reflections in the chirp data) or the central geographic co-ordinates of the chirp
3-4
TAMS/ET March 2005
reflections that corresponded with a target. For the targets associated with chirp reflections, the
positional information (i.e., WGS84 latitude and longitude as logged by the RTK system) was
calculated from the Edgetech data screen during playback. These points were then translated into
NAD83 New Jersey State Plane eastings and northings in feet. The estimate of the positional
accuracy of the RTK system is 1 to 3 cm. The estimation for the layback error is 1 to 2 ft.
Adding the two potential errors generates an error estimate of 1 to 2 ft in the definition of the
geographic location of the identified targets
During the survey, the data were observed in “real-time” on the X-STAR monitor. The data
displayed included the reflection coefficient of the river bottom (a measure of the acoustic
impedance contrast at the water/sediment interface), the relative amplitude of bottom and subbottom reflections, a cross-sectional image of the last ~600 chirp pulses that were recorded, as
well as the current position, time, date, course and speed of the R/V Delaware
3.4.2
Sub-Bottom Profiler Results
As illustrated in Appendix B, three major types of bottom sediments were encountered during
the chirp survey. In shallower water depths along the edges of the channel of the Passaic River,
a soft bottom characterized by fluid muds at the sediment water interface with underlying
organic fine-grained sediments was imaged by the chirp system. The underlying fine-grained
sediments were associated with a high-amplitude chirp reflection most likely due to gas
contained within these sediments. Along the slopes of the channel, gassy silt and clay organicrich sediments were present. The presence of gas, most likely produced by the decay of organic
material within the sediments reduces the penetration of the chirp acoustic signals. In the
deepest portions of the river along the channel, well-consolidated silt and clay sediments with
gas produced a high amplitude reflection at the sediment/water interface. This strong reflection
reduced the amount of chirp energy that could penetrate further into the subsurface.
The presence of gaseous sediments and well-consolidated sediments along the river bottom
prevented the penetration of acoustic signals deeper into the sub-bottom and thus limited the
effectiveness of the chirp system during the survey. Although the chirp system acoustic signal
was able to penetrate in a few areas and image a few targets, overall the sediments present in the
survey area severely limited the acoustic imaging efforts. Due to these gaseous sediments only
two targets identified during the magnetometer survey were partially imaged by the sub-bottom
system. Two other targets were recorded setting the total number of observed target at four (see
Appendix B). Of the two targets that were not associated with magnetic signals, one was
observed at the surface (identified as potential target – surface) and was characterized by a highamplitude, rather square-shaped reflection. The second target (identified as potential target – subsurface) was characterized by reflections that ranged in depth from 3 to 10 ft beneath the surface.
3.5
PROBLEMS ENCOUNTERED
The problem encountered with the magnetic remote sensing survey was the significant amount of
geologic background noise encountered in the survey area. This results in magnetometer records
3-5
TAMS/ET March 2005
that are more difficult to interpret and very small targets may be obscured. Though these objects
would not be of significant size in relation to the dredging operations, they may be important
from a submerged cultural resources standpoint. In order to minimize the effects of geologic
interference, it is recommended that future magnetic surveys in this area be conducted using a
gradiometer rather than a magnetometer.
In terms of using chirp acoustic methods to image targets as identified by the magnetic survey,
there were two major problems that the river bottom presented in the survey. First, the acoustic
reflection coefficient at the bottom surface in the area of the well-consolidated silt/clay
sediments is high. This limited the amount of acoustic energy that penetrated deeper into the subbottom. Second, in areas of fine-grained silts and clays, there were high amplitude returns from
the river bottom. Both of these bottom types were associated with the presence of organic-rich
gaseous sediments in a layer that was mostly unbroken in the survey area. These muds, which
may contain significant amounts of organically produced gas, created situations in which little
acoustic energy traveled below these sediments. Due to these two conditions, the chirp system
was unable to get significant penetration into the sub-bottom. This limited the effectiveness of
the system to image targets in the sub-surface.

SUMMARY, CONCLUSION, AND RECOMMENDATIONS
5.1
SUMMARY
The work as described in the project plans was successfully completed and included the
execution of the geophysical surveys and the collection and analysis of environmental samples.
Work completed included geophysical surveys, sample collection, and sample analysis, as
detailed in this report and summarized below.
5.1.1
Geophysical Surveys
Geophysical surveys were conducted within the specified section of the Harrison Reach of the
Passaic River by a subcontractor, ASI.
A hydrographic survey was performed on a 1000-ft long stretch of the river, from bank to bank,
using 25-ft wide lanes. Drawings generated from the survey show features in the vicinity of the
site on the river bottom.
A side-scan sonar survey was conducted on the same 1000-ft stretch of river as the hydrographic
survey. The side scan sonar survey was performed by running lines parallel to the shoreline on a
50-ft spacing. A mosaic of the riverbed in the study area was created. As part of the side-scan
sonar survey, it was planned to collect 30 surface sediment samples for correlation of the sidescan results with the actual subsurface conditions. However, only seven samples were actually
collected; these were characterized in the field based on the side-scan images and the need to
verify the sediment types associated with signal types.
Subsequent to the completion of the hydrographic and side-scan sonar surveys, a magnetometer
survey and a sub-bottom profiler survey were also performed by ASI. These surveys were
conducted to detect buried ferrous and non-ferrous objects not detected in the side-scan sonar
survey, and also aided in the interpretation of the side-scan sonar results. These surveys
provided information on debris (e.g., the relative size and position of buried objects) as well as
archaeological data (potentially significant historic submerged cultural resources) for compliance
with the National Historic Preservation Act and the Abandoned Shipwreck Act.
Recommendations for further investigation are included in the ASI report in Appendix B.
5.1.2
Sample Collection
The sediment coring and sampling program was conducted from July 12 through July 14, 2004.
Cores with adequate recovery were collected from all 15 grid locations as designated in the
Work Plan (TAMS/ET, 2004). Cores were transferred intact to the R/V Robert E. Hayes
processing facility, where cores were sliced into 1-ft sections (0-1, 1-2, 2-3, and 3-4 ft intervals);
weighed (for bulk density determinations); homogenized, subsampled, and shipped to the
designated laboratories. As specified in the plans, 45 discrete samples (plus QC samples) were
generated, one from each of the three 1-ft intervals (between 0-3 ft) for each of the 15 grid
locations; one additional sample from the 3-4 ft interval was also collected at each grid location
(these samples were shipped to the laboratory but were ‘archived’ – stored frozen at the
5-1
TAMS/ET March 2005
laboratory pending further instructions regarding compositing and analysis of these archive
samples).
In addition to the discrete samples summarized above, several composites were generated for
different purposes. One bulk drum sample (designated as T-17) was obtained by USEPA
personnel for use in treatability studies by potential sediment decontamination technology
vendors; this sample was collected through material obtained by surface grabs (roughly the top
six inches of sediment) using a petite ponar dredge sampler. Other vertical and horizontal
composites were generated for the same analytical parameters (PCB congeners, dioxins/furans)
as described in Section 2. In general, the sampling program was successful in obtaining sufficient
material to perform all the planned analyses.
5.1.3
Sample Analysis
The analytical program was implemented with a high degree of consistency with the program
outlined in the QAPP (TAMS, 2004); very few omissions or changes were made during the
execution of the analytical program. The bullets immediately below summarize the program; the
results were discussed in Section 4 and summarized below in Section 5.2.2.
•
Volatile Organic Compounds. VOC data were only generated for the 45 discrete samples
from the 0-3 ft intervals, and the vendor composite (the archived cores were not analyzed
for VOCs). Analysis was conducted through the CLP and the data were validated by
USEPA Region II personnel.
•
Semivolatile Organic Compounds. SVOC data for the discrete samples from the 0-3 ft
interval were analyzed for the CLP target compound list SVOC analytes. These analyses
were conducted through the CLP and the data were validated by USEPA Region II
personnel. In addition, eight archive cores (3-4 ft interval) were analyzed for 24 PAH
compounds (not the CLP SVOC TCL list) by the DESA laboratory in Edison, NJ; these
data are considered EPA-validated and fully usable as reported.
•
Pesticides. Pesticide data were generated for the 45 discrete 0-3 ft interval cores by the
CLP laboratory; usable data was generated for most of the DDT-related constituents.
However, data were rejected (unusable) for one DDD, one DDE, and 11 DDT results. In
some cases a result was rejected in the diluted but not the initial analysis, or the reverse;
in these cases a usable value was obtained even though one of the results was rejected. In
addition, eight archive 3-4 ft interval cores were analyzed for pesticides by the USEPA
DESA laboratory; these data are considered EPA-validated and fully usable as reported.
•
PCBs (Aroclors). PCB data were generated for the 0-3 ft interval cores by the CLP
laboratory, and eight archive 3-4 ft interval cores were analyzed for PCBs by the USEPA
DESA laboratory. In addition, 15 ‘row’ composites for each depth interval from 0-3 ft
were generated (e.g., a composite of A1-01, A2-01, and A3-01) and analyzed by STL.
STL also analyzed five row composites from the 3-4 ft interval, to correspond with
samples also analyzed for PCB congeners. The CLP Aroclor data were validated by
USEPA Region 2 personnel; and the DESA laboratory data are considered EPA-validated
5-2
TAMS/ET March 2005
and fully usable as reported. The STL PCB aroclor data have not been subject to formal
data quality review.
•
PCB congeners. STL analyzed 20 row composites for PCB congeners (five rows from
each of the four depth intervals from 0-4 ft); for comparability, each of these row
composites was also analyzed for PCBs as Aroclors. The vendor composite, T-17, was
also analyzed for PCB congeners. Although these data have not been formally validated,
the comparability of the total PCB values from the congener method to the STL Aroclor
data was very good, and no significant bias was noted.
•
Herbicides. STL performed the herbicide analysis on the 45 discrete cores from the 0-3 ft
intervals and on eight archived core samples from the 3-4 ft interval. The herbicide data
have not been validated and should be considered preliminary.
•
Dioxins/furans. Dioxins/Furans analysis (by EPA method 1613B) was conducted by STL
on the same 20 samples, plus one field duplicate and the vendor composite, as were
analyzed for PCB congeners. As these data have not been validated, the toxicity
equivalence (TEQ) has not been calculated or presented, and these data should be
considered preliminary.
•
Metals. Analysis was conducted on all 45 of the discrete samples from 0-3 ft and eight
archive (3-4) ft samples by the USEPA DESA laboratory. As such, these data are
considered EPA-validated and fully usable as reported. Analysis was conducted for the
23 target analyte list metals.
•
Total Organic Carbon. TOC analysis (L Kahn Method) was performed on all 45 of the
discrete samples from 0-3 ft and eight archive (3-4) ft samples by the USEPA DESA
laboratory. As such, these data are considered EPA-validated and fully usable as
reported.
•
Geotechnical data. Laboratory geotechnical analyses included percent solids, moisture
content, Atterberg limits (liquid limit, plastic limit, and plasticity index), and specific
gravity (these data are tabulated in this report); and grain size. Geotechnical analyses
were performed on the 45 discrete core sections from the 0-3 ft interval, and on seven to
eight archive core samples from the 3-4 ft interval. All grain size analyses were
performed by the USEPA Region II DESA laboratory. The remaining geotechnical
analyses were performed by STL. Bulk density analysis was performed in the field on
each 1-ft core section from all four depth intervals.

CONCLUSIONS
5.2.1
Geophysical Surveys
The sediment surface cross sections and bathymetry plots within the Pilot Study Survey Area
were presented in Section 3 of this report. The March 2004 hydrographic survey conducted by
ASI shows that a considerable amount of deposition (nearly four feet in the deepest channel
5-3
TAMS/ET March 2005
location) has taken place since the March/April 1995 hydrographic surveys were conducted by
TSI. Lesser amounts of sediment have deposited closer to the shoreline. The deepest portion of
the channel is closer to the northern bank of the river. From this location the sediment surface
slopes more gently towards the southern shoreline.
The side scan sonar survey identified three areas and seven targets within the Pilot Study Survey
Area. These are shown in Appendix B1. Area 1 spans the entire length of the surveyed area and
indicated debris including tires, rocks, poles, and other objects projecting approximately 20 feet
into the river from the north side of the survey. Area 2 also spans the entire length of the
surveyed area and was identified as parallel lines in the sediment extending between 100 and 200
feet off the wall along the north side of the survey. These lines are probably shallow ridges
caused by barges touching the bottom or dragging ropes or chains while transiting the area. Area
3 lies in the southwest portion of the survey area and consists of scattered debris over an
approximately 30 foot wide area extending 500 feet eastwards from the western edge of the
survey area about 90 feet from the southern shoreline. Target 1 appears to be a 15 foot tree
projecting three feet into the water column. Targets 2 and 3 are approximately 26 and 37 foot
long pilings laying on the surface. Target 4 is an approximately 1420 square foot area of
probable differential bottom composition that is probably organic debris. Target 5 is a propeller
mark extending approximately 78 feet to the southwest. Target 6 is an approximately 250 square
foot area of probable differential bottom composition that is probably organic debris. Target 7 is
a propeller mark extending approximately 36 feet to the southeast.
The magnetometer survey revealed twelve distinct magnetic anomalies as well as significant
levels of background geologic interference. Of those twelve targets identified in the
magnetometer survey, only two could be correlated with the reflections in the sub-bottom
profiles. In addition, two potential targets, not detected in the magnetometer survey, were
imaged by the chirp system. None of the targets located were found to have signatures indicative
of historically sensitive cultural resources. These surveys were not able to determine whether the
targets identified would pose a hazard to the dredging pilot study. These surveys and targets are
described further in Appendix B2.
5.2.2
Analytical
Overall, the data met the DQOs established for the project (QAPP, TAMS/ET and MPI 2004).
As noted above, sufficient sediment was obtained so that all the planned analyses could be
conducted.
Volatile Organic Compounds. VOC data were fully usable. VOC concentrations detected were
low (not detected, or less than 12 µg/kg). VOC data were only generated for the samples from
the 0-3 ft intervals (the archived cores were not analyzed for VOCs). VOCs were detected in
only 12 of the 45 discrete samples. Chlorobenzene was the most frequently detected VOC,
reported in eight samples at a maximum concentration of 12 µg/kg.
Semivolatile Organic Compounds. SVOC data for the discrete samples from the 0-3 ft interval
were analyzed for the CLP target compound list SVOC analytes. SVOC compounds other than
PAHs and phthalates were generally not detected. The SVOC data typically show that the lowest
5-4
TAMS/ET March 2005
total PAH concentrations are lowest in the near-surface (0-1 ft interval) samples (with PAHs
detected in only four of the 15 discrete samples from this interval), with the highest
concentrations and the highest frequency of detection (14 of 15 samples) in the 2-3 ft interval.
Eight archive cores (3-4 ft interval) were analyzed for 24 PAH compounds (not the CLP SVOC
TCL list) by the DESA laboratory in Edison, NJ; while PAH compounds were detected in all
eight of the 3-4 ft interval cores, concentrations reported were generally lower than those in the
2-3 ft core sections analyzed by the CLP laboratory Mitkem.
Pesticides. Pesticide data were generated for the 0-3 ft interval cores by the CLP laboratory, and
eight archive 3-4 ft interval cores were analyzed for pesticides by the USEPA DESA laboratory.
DDT and related compounds (DDD and DDE). DDT or related compounds were detected in all
the samples analyzed by both CLP and DESA. Usable data was generated for most of the DDTrelated constituents; however, data were rejected (unusable) for one DDD, one DDE, and 11
DDT results. (In some cases a result was rejected in the diluted but not the initial analysis, or the
reverse; in these cases a usable value was obtained even though one of the results was rejected).
A trend of increasing concentration with depth is less obvious in the samples from 0-3 ft
analyzed by Mitkem. DDD, DDE, and DDT were each detected in at least 80 percent of the valid
sample results. Total DDT (sum of valid detections of DDD, DDE, and DDT) ranged from 50
µg/kg to 1100 µg/kg; in some cases the total may be biased low due to rejection of one (or in one
sample, two) of the three analytes. A different pattern was evident in the DESA pesticide results.
DDD and DDE were each detected in all eight analyses, but DDT was detected in none of the
eight 3-4 ft cores. The total DDT concentrations calculated from the DESA data (representing
the sum of detections of DDD and DDE, as DDT was not detected) were fairly consistent,
ranging from 30 to 48 µg/kg, and in all cases lower than the total DDT result calculated from the
Mitkem data.
PCBs (Aroclors). PCB data were generated for the 0-3 ft interval cores by the CLP laboratory,
and eight archive 3-4 ft interval cores were analyzed for PCBs by the USEPA DESA laboratory.
In addition, 15 ‘row’ composites for each depth interval from 0-3 ft were generated (e.g., a
composite of A1-01, A2-01, and A3-01) and analyzed by STL. STL also analyzed five row
composites from the 3-4 ft interval, to correspond with samples also analyzed for PCB
congeners.
PCB results varied by laboratory. PCBs were detected in 30 of the 48 samples analyzed by
Mitkem (45 discrete environmental samples plus three field duplicates); in samples in which
PCBs were detected, the total PCB concentration ranged from 230 µg/kg to 3800 µg/kg. Aroclor
1254 was the PCB most often reported (in 28 samples), with less frequent detection of Aroclor
1242 (10 samples) and 1260 (one sample). In the 0-3 ft interval row composites analyzed by
STL, total PCB concentrations were higher (ranging from 1220 µg/kg to 7400 µg/kg); and
Aroclors 1248 and 1254 were reported as present in all of these samples. No other Aroclors were
reported present by STL. In the eight archive 3-4 ft samples analyzed by DESA, Aroclor 1248
was the only Aroclor reported, at concentrations ranging from 380 to 780 µg/kg. STL data for
five row composites from the same depth interval (although not from identical material analyzed
by DESA) indicated PCB concentrations higher than those reported by DESA, typically by a
factor of greater than 10, ranging from 8400 to 12,200 µg/kg. Two Aroclors were reported in
5-5
TAMS/ET March 2005
each of the five 3-4 ft row composites analyzed by STL: Aroclor 1248 in all five samples, and
Aroclor 1254 in four, with Aroclor 1260 reported in the other sample.
PCB congeners. STL analyzed 20 row composites for PCB congeners (five rows from each of
the four depth intervals from 0-4 ft); for comparability, each of these row composites was also
analyzed for PCBs as Aroclors. The vendor composite, T-17, was also analyzed for PCB
congeners. Overall the comparability of the total PCB values from the two methods was very
good, and no significant bias was noted. Overall, the total PCB congener concentration average
was greater than the sum of Aroclors value by about 7 percent, and the median total congener
concentration was greater than the sum of Aroclor median by less than 3 percent.
Herbicides. STL performed the herbicide analysis on the 45 discrete cores from the 0-3 ft
intervals and on eight archived core samples from the 3-4 ft interval. Only 2,4-D and 2,4,5-T
were target analytes in this analysis. Herbicides were detected infrequently. 2,4-D was detected
in four samples (plus in one duplicate), at concentrations ranging from 260 to 750 µg/kg; and
2,4,5-T in three samples at concentrations ranging from 40 to 67 µg/kg. No herbicides were
detected in any of the 3-4 ft interval samples, nor in the 0-1 ft interval samples. The herbicide
data have not been validated and should be considered preliminary.
Dioxins/furans. Dioxins/Furans analysis (by EPA method 1613B) was conducted by STL on the
same 20 samples, plus one field duplicate and the vendor composite, as were analyzed for PCB
congeners. As these data have not been validated, the toxicity equivalence (TEQ) has not been
calculated or presented, and these data should be considered preliminary. Total TCDD and
2,3,7,8-TCDD data were tabulated; both were detected in all samples analyzed by were not
detected in the field blank. These data do show a trend of increasing concentration with depth.
Metals. Analysis was conducted on all 45 of the discrete samples from 0-3 ft and eight archive
(3-4) ft samples by the USEPA DESA laboratory. As such, these data are considered EPAvalidated and fully usable as reported. Analysis was conducted for the 23 target analyte list
metals, although the discussion focuses on mercury and lead. Mercury was detected in every
sample analyzed, at concentrations ranging from 1.4 to 12 mg/kg. Lead was also detected in
every sample analyzed, at concentrations ranging from 210 to 1100 mg/kg. For both mercury and
lead, there is a general trend of increasing concentration with depth. Field duplicate precision
was good, and no TAL metals were detected in the field blank.
Total Organic Carbon. TOC analysis (L Kahn Method) was performed on all 45 of the discrete
samples from 0-3 ft and eight archive (3-4) ft samples by the USEPA DESA laboratory. As such,
these data are considered EPA-validated and fully usable as reported. TOC values ranged from
46,000 mg/kg (4.6 percent) to 81,000 mg/kg (8.1 percent). There was no discernible trend of
TOC concentration with depth. Field duplicate precision was good.
Geotechnical data. Geotechnical analyses included percent solids, moisture content, Atterberg
limits (liquid limit, plastic limit, and plasticity index), and specific gravity (these data are
tabulated in this report); grain size (shown on Figure 4-14); and bulk density analysis, performed
in the field and shown on Table 2-4. Geotechnical data were not subject to formal data quality
review.

TAMS/ET March 2005
Percent solids data and moisture content (ASTM D2216) data are in good agreement, after
accounting for the different data reporting conventions of the two methods. These data show the
expected trend of increased solids content with depth. The average solids content is 36.6 percent
in the 0-1 ft interval, 43 percent in the 0-2 ft interval, and 48 percent in the 2-3 ft interval. Solids
results reported by different laboratories on the samples from the same interval are in good
agreement, generally agreeing to within ± 4 percent.
Atterberg limits results were reported for liquid limit, plastic limit, and plasticity index. For two
samples (B1-01 and B3-12), the plasticity index and limit were not performed or no usable value
was reported. Liquid limit values ranged from 50 to 116, with an average LL of 71.2 and a
median of 66. Plastic limits ranged from 34 to 56 with an average of 44.2 and a median of 43.
Plasticity index results ranged from 11 to 63, with an average of 27.3 and median of 24 for the
43 discrete samples for which data were reported.
Specific gravity analyses were performed by ASTM D854. Specific gravity values (density of
dry solids) ranged from 2.06 to 2.56, with an average of 2.35 and a median of 2.34.
Grain size data are shown on Figure 4-14. Grain size analysis was conducted on 43 of the 45
discrete samples from the 0-3 ft interval (no data are available for the 0-1 ft interval from C3 and
E2), and eight archive 3-4 ft interval samples. Silt is the predominant grain size fraction,
typically representing 70 to 80 percent of the sample; it is the dominant fraction in all but one of
the samples analyzed. The sand fraction was highly variable, ranging from 5 percent to a
maximum of 50 percent. The clay fraction was generally low, with a maximum value of less than
10 percent.
5.3
RECOMMENDATIONS
5.3.1
Geophysical
In order to minimize the effects of geologic interference, ASI recommended that future magnetic
surveys in this area be conducted using a gradiometer rather than a magnetometer.
5.3.2
Analytical
Based on the review and evaluation of the procedures used and the results of the sediment coring
program described herein, the following recommendations are presented.
•
Formal data quality review (e.g., validation) should be conducted for the chemical
parameters which is not ‘EPA-validated’ upon release nor was validated subsequent to
generation. Of especial significance is the PCDD/PCDF (dioxin/furan) data, for which
the laboratory case narrative have indicated that there were some problems with surrogate
recoveries. Other chemical data which have not been formally reviewed to date include
the herbicide data and PCB congener data.
5-7
TAMS/ET March 2005
•
Review of the samples analyze for PAH constituents only, in which seven more PAH
compounds were reported than in the samples analyzed for the 17 PAH constituents
reported in the typical SVOC analysis, shows that these additional seven PAH
compounds comprise a consistent fraction of the total PAH concentration. Therefore,
analysis for the additional PAH constituents is not necessary for samples in which data
for the individual additional compounds is not needed.
•
Data comparability would be enhanced by use of a single laboratory for all analyses of
the same or similar parameter. Review of the PCB (Aroclor) results generated for this
study suggests that there is variability both in the identification and quantitation of
Aroclors reported among the three different laboratories which performed this analysis.
There also seems to be similar variability between pesticide results reported by the CLP
laboratory and the USEPA Region II DESA laboratory.
•
Agreement between total PCB as Aroclor results and total PCBs as sum of detected
congener results were in good agreement for split samples analyzed by the same
laboratory. Therefore, it is likely that the less costly PCB Aroclor method provides
adequate quantitation of PCBs for sample data for which further information regarding
the PCB constituents is not needed.
•
General agreement was good between percent solids (using a simple drying and weighing
method) and moisture content data reported by ASTM D2216. This agreement suggests
that moisture analysis by ASTM D2216 is probably redundant and is not necessary for
future sampling events.

SUMMARY
The goal of the debris survey was to identify buried objects that may be hazards to the
dredging operation in the proposed pilot study area (Figure 1). Both sub-bottom and
magnetometer surveys were conducted in an attempt to identify objects buried beneath the
surface of the sediment.
The survey work encompassed the entire river bottom, to the MLW mark along each
shoreline. The survey extended for 1000 feet along the river centerline from bank to bank
(Figure 1). The survey work was conducted in NAD83 and NJ State Plane feet (horizontal
datum) and NGVD 1929 for the vertical datum.
A Geometrics G-882 marine cesium magnetometer system was used for the initial
magnetometer survey. During the survey, the sensor was towed at a depth of 1 to 5 feet and
approximately 40 feet behind the survey vessel to ensure the sensor was not detecting the
vessel itself.
An Edgetech X-STAR chirp sonar system was used with a SB-216S towfish to perform subbottom profiling along the Harrison Reach of the Passaic River. During the survey, the SB216S was towed at a depth between 3 and 6 ft. and approximately 6 ft. aft of the navigational
antenna on the port side of the Aqua Survey, Inc. vessel R/V Delaware.
Surveys lines were initially surveyed using a magnetometer, then subsequently surveyed
using the X-STAR sonar. The magnetometer survey revealed 12 distinct magnetic anomalies
as well as significant levels of background geologic interference. Of those 12 targets
identified by the magnetometer survey only two could be correlated with reflections in the
sub-bottom profiles. In addition to these two targets, two potential targets, not detected in
the magnetometer survey, were imaged by the chirp system. Images of the magnetic
signatures as well as the four targets observed on the chirp profiles are shown within the text
of this report.
None of the targets located were found to have signatures indicative of historically significant
submerged cultural resources. Because all of the materials generating the targets are buried
below the surface of the sediment, it is impossible to positively identify them using remote
sensing equipment. Whether the targets identified are a concern for the future dredging
operations cannot be determined. Should the potential exist for the dredging equipment to
be damaged by the targets, further investigation may be necessary to determine the nature and
depth of burial of the material generating the anomaly. This could be accomplished using jet
probing to delineate the size and shape of the object as well as its depth of burial.

MATERIALS, METHODS, AND RESULTS
A.
Magnetometer Data Collection
A magnetometer survey was conducted in order to detect the presence of buried ferrous
debris not detected during the side-scan sonar survey. The magnetometer survey also
complemented and aided in the interpretation of the side-scan sonar survey results, gathered
from a survey in the spring of 2004, regarding debris and potentially significant historic
submerged cultural resources. The survey methodology was designed to provide data
indicating the position, and relative size of ferrous targets in the survey area, as well as
archaeological data essential for complying with the National Historic Preservation Act of
1966, as amended, through 1992 (36 CFR 800, Protection of Historic Properties) and the
Abandoned Shipwreck Act of 1987 (Abandoned Shipwreck Act Guidelines, National Park
Service, Federal Register, Vol. 55, No. 3, December 4, 1990, pages 50116-50145).
A Geometrics G-882 marine cesium magnetometer system magnetometer capable of plus or
minus 0.01 gamma resolution was be used to conduct the survey. Survey lines were run at
25-foot intervals to ensure complete coverage of the survey area. Data was recorded at 0.5
second intervals and electronically paired with positioning data from a real-time kinematic
global positioning system using an onboard computer running Hypack Max 4.3 survey
software.
To ensure reliable target identification and assessment, analysis of the magnetic data was
initially carried out as it is generated. Significant magnetic anomalies were marked as targets
during the survey and were re-surveyed using the magnetometer to better determine the size
and characteristics of the anomaly.
Post-processing of the data involved examining each survey line individually and annotating
anomalies detected. Using contouring software, magnetic data generated during the survey
was contour plotted at 10 gamma intervals for analysis and accurate location of the material
generating each magnetic anomaly as well as determining the presence of clusters of targets.
Magnetic targets were isolated and analyzed in accordance with intensity, duration, areal
extent and signature characteristics.
Data generated by the remote sensing equipment was used to support an assessment of each
magnetic signature. Analysis of each target signature included consideration of magnetic
characteristics previously demonstrated to be reliable indicators of historically significant
submerged cultural resources. Assessment of each target includes recommendations for
additional investigation to determine the exact nature of the cultural material generating the
signature and its potential National Register significance. All targets are listed and described
and a map has been produced that shows their location within the project area (Figure 2).

Magnetometer Results
A Geometrics G-882 marine cesium magnetometer system was used for the magnetometer
survey. During the survey, the sensor was towed at a depth of 1 to 5 feet and approximately
40 feet behind the survey vessel to ensure the sensor was not detecting the vessel itself. The
magnetometer survey revealed 12 distinct magnetic anomalies as well as significant levels of
background geologic interference. The location of each of the magnetic anomalies was
checked on the side-scan sonar mosaic and no targets were duplicated in the two surveys.

The magnetic signature was identified on lane 4. The target is located just outside the eastern
edge of study area by 35 feet, but was marked due to its intensity. The location of this target
is shown in figure 2. The detectable monopolar negative signature had a maximum intensity
of 1132 gammas and was detected for 100 linear feet. Analysis of the magnetic signature
suggests that material generating the anomaly is associated with a single large ferrous object
and does not represent the complex type of signature generally associated with shipwreck
sites. The magnetic anomaly does not correspond to any targets detected in the earlier sidescan sonar survey. The signature was not found to have characteristics indicative of
historically significant submerged cultural resources.

Sub-Bottom Profiler Data Collection
An Edgetech X-STAR sonar system with a SB-216S towfish (Figure 15) was used to collect
the chirp sub-bottom profiling data during a survey along the Harrison Reach of the Passaic
River. The principal objective of the survey was to collect chirp images along lines that had
been previously surveyed with a magnetometer.
Chirp profilers use acoustic methods to generate high-resolution (on the order of 0.5-1 ft)
cross-sectional images of the marine sub-bottom to depths of up to 100 ft beneath the
seafloor. These profilers transmit a wide band FM sound pulse that is linearly swept over a
full spectrum frequency range (i.e., a “chirp”). The transmitted sound pulses travel through
the water column and sub-bottom and are reflected when changes in acoustic impedance
(equivalent to a material’s sonic velocity times its density) are encountered. Acoustic
impedance changes commonly occur at boundaries between materials (e.g., interfaces
between water and sediments, sediments and gas, and sediments and buried objects). The
reflected sound pulses travel back to the profiler where their amplitudes, as a function of
travel-time, are digitally recorded.
During the survey, the SB-216S was towed at a depth between 3 and 6 ft. It was towed
approximately 6 ft aft of the navigational antenna on the port side of the Aqua Survey, Inc.
vessel Delaware. The SB-216S emitted a chirp sound pulse with a frequency range of 2-15
kHz, eight times per second. Given this sampling interval with an average speed of 1 to 2
knots, the horizontal spacing between individual pulses displayed on the chirp profiles was
on the order of 0.2-0.5 ft.
Geographic position (i.e., latitude and longitude) along the chirp profiles was determined
with Trimble RTK Positioning System (Model # 5700). The data from the RTK were also
used by the HYPACK helm guidance and position recording software. These navigational
data were logged at one-second intervals by HYPACK and the X-STAR digital recording
system.

time (in GMT) marks along the track lines. Red circles are targets identified

132949 and 133328. Red rectangle denotes target that was identified on the chirp
profiles that was not associated with a corresponding magnetic anomaly.
Figure 16.
Track lines of the Delaware during the chirp survey.
To correct the navigational data to the position of the SB-216S, we estimated its layback
(distance aft of the navigational antenna) during the survey while at the average towing speed
of 1-2 knots. This distance of about 6 ft was used to correct the SB-216S position relative to
the navigation data. The navigational data for the targets identified in the earlier magnetics
survey and their corresponding positions along the chirp profiles are presented in Table 1
along with one potential target identified in the chirp data that was not associated with a
magnetic anomaly. Along the chirp profiles, the position of the magnetics targets were
identified as either the closest profile position to the target (i.e., in the case that the target was
not associated with reflections in the chirp data) or the central geographic co-ordinates of the
chirp reflections that corresponded with a target. For the targets associated with chirp
reflections, the positional information (i.e., WGS84 latitude and longitude as logged by the
RTK system) was calculated from the Edgetech data screen during playback. These points
were then translated into NAD83 New Jersey State Plane eastings and northings in feet. The
estimate of the positional accuracy of the RTK system is 1 to 3 cm. The estimation for the
layback error is 1 to 2 ft. Adding the two potential errors generates an error estimate of 1 to 2
ft in the definition of the geographic location of the identified targets.

During the survey, the data were observed in “real-time” on the X-STAR monitor (Figure

the acoustic impedance contrast at the water/sediment interface), the relative amplitude of
bottom and sub-bottom reflections, a cross-sectional image of the last ~600 chirp pulses that
were recorded, as well as the current position, time, date, course and speed of the R/V
Delaware.

position of this track line is shown in Figure 2. The presence gas in organic, gassy
sediments and well-consolidated silt/clay sediments along the river bottom
prevented the significant penetration of the chirp acoustic signal.

Sub-bottom Profiler Results
As shown in Figure 18, three major types of bottom sediments were encountered during the
chirp survey. In shallower water depths along the edges of the channel of the Passaic River,
a soft bottom characterized by fluid muds at the sediment water interface with underlying
organic fine-grained sediments was imaged by the chirp system. The underlying fine-grained
sediments were associated with a high-amplitude chirp reflection most likely due to gas
contained within these sediments. Along the slopes of the channel, gassy silt and clay
organic-rich sediments were present. The presence of gas, most likely produced by the decay
of organic material within the sediments reduces the penetration of the chirp acoustic signals.
In the deepest portions of the river along the channel, well-consolidated silt and clay
sediments with gas produced a high amplitude reflection at the sediment/water interface. This
strong reflection reduced the amount of chirp energy that could penetrate further into the
subsurface.

Targets as identified by magnetic and chirp surveys.
The presence of gaseous sediments and well-consolidated sediments along the river bottom
prevented the penetration of acoustic signals deeper into the sub-bottom and thus limited the
effectiveness of the chirp system during the survey. Although the chirp system acoustic
signal was able to penetrate in a few areas and image a few targets, overall the sediments
present in the survey area severely limited the acoustic imaging efforts. Due to these gaseous
sediments only two targets identified during the magnetometer survey were partially imaged
by the sub-bottom system. Two other targets were recorded setting the total number of
observed target at four (Figures 19-22). Of the two targets that were not associated with
magnetic signals, one was observed at the surface (identified as potential target – surface)
and was characterized by a high-amplitude, rather square-shaped reflection (Figure 19). The
second target (identified as potential target – sub-surface) was characterized by reflections
that ranged in depth from 3 to 10 ft beneath the surface (Figure 20).

Problems Encountered
The only problem encountered with the magnetic remote sensing survey was the significant
amount of geologic background noise encountered in the survey area. This results in
magnetometer records that are more difficult to interpret and very small targets may be
obscured. Though these objects would not be of significant size in relation to the dredging
operations, they may be important from a submerged cultural resources standpoint. In order
to minimize the effects of geologic interference, it is recommended that future magnetic
surveys in this area be conducted using a gradiometer rather than a magnetometer.
In terms of using chirp acoustic methods to image targets as identified by the magnetic
survey, there were two major problems that the river bottom presented in our survey. First,
the acoustic reflection coefficient at the bottom surface in the area of the well-consolidated
silt/clay sediments is high. This limited the amount of acoustic energy that penetrated deeper
into the sub-bottom. Second, in areas of fine-grained silts and clays, there were high
amplitude returns from the river bottom. Both of these bottom types were associated with the
presence of organic-rich gaseous sediments in a layer that was mostly unbroken in the survey
area. These muds, which may contain significant amounts of organically produced gas,
created situations in which little acoustic energy traveled below these sediments. Due to
these two conditions, the chirp system was unable to get significant penetration into the subbottom. This limited the effectiveness of the system to image targets in the sub-surface.
