Final Remedial Investigation Report and Focused Feasibility Study [April 2014]
The Remedial Investigation Report (RI) describes the nature and extent of contamination in the sediments of the lower 8
miles of the Lower Passaic River and the risks to human health and the environment posed by exposure to that contamination.
The Focused Feasibility Study (FFS) evaluates a range options to clean up the contaminated sediments in the lower 8 miles
(called remedial alternatives). The files that are part of the RI and FFS can be downloaded and reviewed by clicking on the links below:

There have been some problems reported when downloading Appendix A. For convenience, links to the individual data evaluation reports are provided below.
Appendix A Individual Reports:

The RI and FFS provide information that supports the Proposed Plan, described and available for download on the “Home” page.
The figures that are part of the Proposed Plan are attached to the
text and available for download on the “Home” page. However, the text
also refers to certain figures in the RI, FFS and appendices that the
reader may want to review for more in-depth information.
Those figures have been gathered here for convenience:
RI-FFS-Appendix Figures for Proposed Plan.
Additional fact sheets related to the FFS and Proposed Plan are posted in the Digital Library, under Public Outreach\Fact Sheets.
Meetings Held During the Public Comment Period [April 2014 through August 2014]
Following are meetings held during the public comment period between EPA and non-governmental stakeholders that included substantive
discussions regarding the Proposed Plan and Focused Feasibility Study. These meetings are being documented in accordance with EPA’s
Superfund Community Involvement Handbook (EPA 540-K-05-003) and will become part of the administrative record. Agendas and/or notes
from the meetings are available in the Digital Library, under “All Public Documents”, “Passaic River Lower 8 Mile Action” folder.
Passaic River Community Advisory Group materials are available under “Public Outreach\Community Advisory Group”.

Final Lower Passaic River Commercial
Navigation Analysis [July 2010]
This document presents the current status of
commercial navigation use on the Lower Passaic River.
The previous two drafts (March 2007 and December 2008)
have been updated to reflect input provided by
commercial users of the navigation channel. To review
this report, please
Sampling Activities to Support the Early
A sampling event has been planned to gather data to
support the Empirical Mass Balance Model in the FFS.
Attached are the work plan documents that describe the
sampling. Please click here to download the
Quality Assurance Project Plan (QAPP)/Field Sampling
Plan (FSP) Addendum and
Sediment Trap Amendment.
Sampling has been planned in the surface sediments of
River Mile 0 - 1 to fill in data gaps for the Early
Action evaluation. Attached are the work plan documents
that describe the sampling. Please

Sampling and lab experiments are being planned to
determine Passaic River sediment erosion rates using a
device named "Sedflume". Erosion rates will be used in
sediment transport modeling to characterize sediment
stability or the potential for sediments to move.

Draft Focused Feasibility Study (FFS) [June, 2007]
The Focused Feasibility Study (FFS) evaluates a range
of alternatives that might be implemented to control the
sediments of the lower eight miles of the Passaic River.
A draft FFS is being reviewed by the Remedial Options
Work Group. The files that comprise the draft FFS can be

Note that the due date for comments from the work
group recently was extended to August 16, 2007 from the
date shown in the presentations.
On May 7, 2008, the Remedial Options Work Group met
to hear an update on work being done to address comments
on the draft FFS. The discussion focused on how the
remedial alternatives would be updated (click
