Brief History of Events
Diamond Alkali owned/operated pesticide
manufacturing facility at 80 Lister Avenue from 19511969
EPA and NJDEP collected dioxin contaminated
samples at the site in 1983 and in 1984 the site was
added to the NPL
The construction of the interim remedy, consisting of
a floodwall, a cap and a groundwater pump and treat
system, was completed at the site in 2004
Brief History of Events (cont’d)
Separate consent agreements were entered into for
the study of the Lower Passaic River and Newark
Bay and its tributaries in 2004
Tierra Solutions, Inc is studying Newark Bay on
behalf of Occidental Chemical and EPA is providing
oversight with its consultants and with input from the
Trustees
This study is a multi-phase, multi-year effort, of
which a couple of Phases have been completed

Preliminary Conceptual Site Model
Geomorphic Features
• 7 major geomorphic features influence
hydrodynamics and sediment transport:
–
–
–
–
Navigation Channels
Port Channels
Transitional Slopes
Sub-tidal Flats
– Inter-tidal Areas
– Industrial Waterfront
– Confined Disposal Facility
Hydrodynamics
• Complex and
varying circulation
patterns depending
on location, tides,
winds, and
freshwater flows
Sediment Transport
• Extensive dredging has modified/
obscured historical contaminant profiles,
created preferential deposition areas and
removed contaminated sediment
• Deposition rates relatively low in flats

Geomorphic Areas

Phase 1 Program and
Preliminary Findings
7
Primary Phase 1 Data Quality
Objectives
• RI Goal 1 (Nature/Extent)
– Estimate approximate depth of 1940 horizon
– Understand broad patterns of contaminants of potential
concern in sediments and attempt to preliminarily identify
“hot spots”
– Confirm presence and extent of geomorphic areas
– Confirm that analytical suite is appropriate for the various
geomorphic areas
– Determine data needs for Phase II
8
Phase 1 Data Quality Objectives
(cont’d)
• RI Goal 2 (Risk Assessment)
– Preliminarily characterize sediment contamination in ecologically
sensitive inter-tidal mudflats
– Estimate depth of Biologically Active Zone within various
geomorphic areas
• RI Goal 3 (Source Identification)
– Gather information to identify ongoing sources of contaminants
– Confirm (through sediment sampling) current and historical
discharges impacting select areas
9
Bathymetric Survey
10
Phase 1 Bathymetric Survey
• Completed by Ocean
Surveys, Inc., in October
2005
• Performed to verify
geomorphic areas and to
assist field crew in locating
Transitional Slope cores
• Bathymetric data confirmed
presence of distinct
geomorphic features within
the Bay
11
Biologically Active Zone
Investigation
12
Phase 1 Biologically Active Zone (BAZ)
Investigation: Overview
• Completed in October 2005
• Performed to estimate depth of the BAZ
• Obtained Sediment Profile Images (SPI)
and grab samples at 14 locations across
the Bay
• Compared field results with literature on
BAZ depth
Burrow
Oxic Void
SPI Image: NB01SED038-3
13
Phase 1 Biologically Active Zone (BAZ)
Investigation: Preliminary Findings
• BAZ depth relatively consistent across Newark Bay
(approximately 6 inches)
• BAZ thickness corresponds well with depths estimated in
other studies
Note: These preliminary findings are subject to change pending Tierra’s responses to USEPA
comments, and based upon the receipt of new information/data.
14
Sediment Coring
15
Phase 1 Sediment Coring: Overview
• Field work conducted from October through December
2005

DESCRIPTION: Deepen highlighted channels to

York and New Jersey sponsorship and support.

STATUS:
‹Deepening Construction began in 1999
‹In 2005, Corps began new NEPA evaluations
regarding continued HDP construction in light
of the AOC on the NBSA and related litigation.
‹Corps commented to EPA in 2005 on Phase 1
work plan to sample a few known historically
deep areas that were now shallow
‹Phase 1 data appeared to support prior Corps
hypothesis regarding sediment deposition
patterns within Newark Bay
‹In 2006, Corps, with consultant (Earthworks)
support, expanded historical geomorphological
study of Newark Bay in support of draft

Mapping Historical and Future (planned)
Bay Bathymetry
Using historical maps and other data
sources, 3D models of Newark Bay
bathymetry and shoreline were created
for selected time periods (keyframes)
Past time periods modeled in 3D
include: 1855, 1886, 1917, 1934, 1944,
1969, and 1989
Using surveys and plans for future HDP
construction and EPA’s Phase 1 survey
data, keyframes for present and
upcoming years also modeled in 3D:
2006, 2008-2012
Models illustrate dynamic and changing
nature of Bay over past 150 years
