With the approval of the bioaccumulation model (Appendix P), EPA has finalized the 17-mile Remedial Investigation Report which can be accessed here. [January 2023] Final Remedial Investigation Report [July 2019] The Remedial Investigation Report (RI) for the LPRSA characterizes the distribution of contaminants in sediment, surface water, and biota, their fate and transport, and the risks they pose to human and ecological receptors. The files that are part of the RI can be downloaded and reviewed by clicking on the links below: Remedial Investigation Report (RI Report) Text Tables Figures Appendix A – Navigation Channel and Bathymetry Appendix B – Data Characterization Reports Appendix C – Data Validation Reports (These reports can be provided upon request) Appendix D – Risk Assessment Reports: BERA and HHRA Appendix E – Electronic Data Appendix F – Nature and Extent of Chemicals of Potential Concern Supporting Material: Biota Appendix G – Evaluation of Contaminant Water Column Appendix H – Supplementary Evaluations of Small Volume Chemical Water Column Monitoring Data Appendix I – Details of Data Treatment for Sediment Core Analyses Appendix J – Mapping of Contaminant Concentrations in Lower Passaic River Sediments Appendix K – Section 4 Supporting Figures Appendix L – Hydrodynamic Model of the LPR Appendix M – Sediment Transport Model of the LPR Appendix N – Organic Carbon Model of the LPR Appendix O – Contaminant Fate and Transport Model for the Lower Passaic River Study Area Appendix P – Bioaccumulation Model (This model is still under development) Appendix AA – Regression Plots of Length versus Tissue Concentration for Biota
Risk Assessment
The partner agencies will use sediment, water, and biota data collected under "Sampling Activities" to describe how much risk the contaminants in the river pose to human health and the environment now and in the future under various remediation scenarios. Final Baseline Ecological Risk Assessment [June 2019] The baseline ecological risk assessment (BERA) presents the results of the ecological risk assessment prepared as part of the LPRSA remedial investigation/feasibility study of the 17.4-mile stretch of the Passaic River between Dundee Dam and Newark Bay. Click here to download the BERA report. Click here and expand the Risk Assessment\Passaic River 17-Mile list item for the appendices. Final Baseline Human Health Risk Assessment [July 2017] The purpose of the baseline human health risk assessment (BHHRA) is to provide risk managers with an understanding of the potential current and future risks to human health and the environment that may be posed by a site in the absence of remediation or exposure controls, and the uncertainties associated with the assessment, and to inform the public regarding risks.
