Surface Sediment Chemical Analyses and Benthic Invertebrate Toxicity and Bioaccumulation Testing Quality Assurance Project Plan [October 2009]
This report provides detailed procedures for conducting the second biota sampling events, which will focus on surface sediments and benthic invertebrates. It includes information such as the sample locations and numbers, the sampling techniques that will be utilized, and the laboratories and methods that will be used to analyze the samples. The plan is consistent with the overall roadmap presented in the Problem Formulation Document, which was prepared for the 17-mile RI/FS (July 2009). The data will be used to prepare the human health and ecological risk assessments. Click here to download the report.
Fish/Decapod Tissue Chemistry Analysis and Fish Community Survey Quality Assurance Project Plan [August 2009]
This report provides detailed procedures for conducting the first of the biota sampling events, which will focus on fish and decapods. It includes information such as the sample locations and numbers, the sampling techniques that will be utilized, and the laboratories and methods that will be used to analyze the samples. The plan is consistent with the overall roadmap presented in the Problem Formulation Document which was prepared for the 17-mile RI/FS (July 2009).

Updated Lower Passaic River Commercial Navigation Analysis [December 2008]
This document presents the current status of commercial navigation use on the Lower Passaic River. The draft of this report (March 2007) was presented in Appendix F in the Draft Source Control Early Action Focused Feasibility Study (June 2007). The updated report incorporated additional information from two data sets obtained from the IWR Waterborne Commerce Statistics including: (1) general trends from 1980 to 2006 and (2) current berth by
berth uses of the waterway for the most recent ten years available (1997-2006). The analysis presents a qualitative evaluation of commodities, tonnage, and loaded drafts for all active berths. The August 2008 Conditions Survey was used to present average and controlling depths for each authorized reach of the federal navigation channel. To review this report, please click here.
Vegetation Sampling, Wetland Delineation, and Bio-Benchmark Report [December 2008] and Plant Resource Document [October 2008]
The USACE conducted vegetation studies at selected sites along the Lower Passaic River (Brackish, Transitional, and Freshwater sections), tributaries of the river and at reference sites during fall 2007 and spring 2008.
Wetland delineations and bio-benchmarking were also conducted at select locations. The Vegetation Sampling Report documents the methods and findings of the sampling events. The vegetation sampling results were used for the preparation of a Plant Resource Document, which provides a comprehensive list of plant species, recommended plantings zones, planting windows, and habitat recommendations to be restored. Both of these documents provide information that will aid in future restoration sampling and planning efforts for the Study.

EPA Makes Cleanup Decision Final For First Phase of Passaic River Cleanup
EPA, in consultation with the New Jersey Department of Environmental Protection, has selected a final cleanup plan for the first stage of a two-phased project to remove dioxin-laden sediment from the lower Passaic River. The cleanup plan, outlined in an Action Memorandum,
signed by EPA on January 9, 2009, involves mechanical dredging of 40,000 cubic yards of sediment with mechanical processing to dewater the sediment on land nearby.
