  • Beneficial Use of Contaminated Sediments: A Review of Technical, Policy, and Regulatory Needs

    Abstract: This special report summarizes key results from the March 2024 Sediment Management Working Group (SMWG) Contaminated Sediment Beneficial Use Workshop sponsored by US Army Engineer Research and Development Center’s (ERDC’s) Advanced Materials and Substances of Emerging Environmental Concern (AMSEEC) center, a multilaboratory research collaborative reviewing solutions to environmental challenges, and the Dredging Operations Environmental Research (DOER) Program, the navigational dredging research arm of ERDC. The workshop focused on potential avenues for treatment and management of contaminated sediments to support expanded beneficial use (BU) opportunities. AMSEEC, with support from DOER, sponsored four pilot studies to advance the technical aspects of the workshop program and partnered with the SMWG, an industry consortium, to organize the workshop in Washington, DC. The workshop was attended by more than 75 practitioners and relevant stakeholders to review these pilot studies and the challenges of advancing treatment and management of contaminated sediment to support BU. This special report summarizes and prioritizes technical, regulatory, and policy needs to enable expanded BU opportunities for contaminated sediments.
  • Northeast Florida Regional Sediment Management: A Guide to Using Dredged Material for Estuarine Restoration

    Abstract: Regional sediment management is a systems approach using best management practices for more efficient and effective use of sediments in coastal, estuarine, and inland environments. The primary RSM objective for this Northeast Florida study is to determine what opportunities exist to beneficially use dredged material for ecosystem restoration and habitat enhancement. A secondary objective is to ensure more efficient use of federal funds by coordinating dredging schedules for navigation projects with federal, state, and local authorities. This study met these objectives through collaboration with stakeholders on the technical, social, and cultural components required to combine resources to meet common goals. The Federal Standard for navigation projects in Northeast Florida is either upland disposal or disposal at the Jacksonville Ocean Dredged Material Disposal Site. This document describes five beneficial uses of dredged material: (1) thin-layer placement, (2) island creation and restoration, (3) dredged hole filling, (4) shoreline stabilization, and (5) upland beneficial use. Dredged material from navigation projects throughout Northeast Florida was considered, including Fernandina Harbor, Kings Bay Naval Submarine Base, Jacksonville Harbor, St. Augustine Inlet, Ponce De Leon Inlet, and the Atlantic Intracoastal Waterway. For each placement strategy, the document outlines the required sediments, volumes, construction methodologies, and estimated costs.
  • USACE Jacksonville District issues proposed Finding of No Significant Impact and Environmental Assessment for the dredging of Atlantic Intracoastal Waterway, Reach 1 in Nassau County

    (October 14, 2025) - The U.S. Army Corps of Engineers, Jacksonville District (Corps) has issued a proposed Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for the maintenance dredging of the federally authorized Atlantic Intracoastal Waterway (AIWW) within waters of the Nassau Reach 1 channel in Nassau County, Florida.
  • USACE awards maintenance dredging contract of Intracoastal Waterway near St. Lucie, Jupiter Inlets

    U.S. Army Corps of Engineers, Jacksonville District, awarded a contract for the maintenance dredging of Federal navigation channels within the Intracoastal Waterway (IWW), starting near Jupiter and continuing near the St. Lucie Inlet, for the amount of $7.2 million to Southwind Construction of Evansville, Indiana.
  • Army Corps awards contract for maintenance dredging for Philadelphia to Trenton portion of Delaware River

    The U.S. Army Corps of Engineers’ Philadelphia District awarded a contract to Cottrell Contracting Corp. of Chesapeake, Va. for $5.36 million to conduct maintenance dredging of portions of the Delaware River between the PA-NJ Turnpike Bridge and the north end of Newbold Island as well as the Fairless Turning Basin. Work is part of the Delaware River, Philadelphia to Trenton federal navigation project.
  • Army Corps awards contract for maintenance dredging of Delaware River and Wilmington Harbor

    The U.S. Army Corps of Engineers’ Philadelphia District awarded a contract to Norfolk Dredging Company for $27.6 million to conduct maintenance dredging of portions of the Delaware River and Wilmington Harbor federal shipping channels.
  • Understanding Hurdles to Expanded Beneficial Use of Dredged Sediment: Stakeholder Perspectives

    Purpose: This technical note (TN) is the second in a series of investigative reports seeking pathways and opportunities to expand beneficial use (BU) of dredged material (DM). This TN summarizes the results of stakeholder outreach and feedback on perceptions about potential BU barriers to be overcome. The purpose of the study was to aid the US Army Corps of Engineers (USACE) dredging and DM management practices, specifically BU of DM (hereinafter BUDM), that USACE manages from various navigation channels and ports around the nation. Per the 28 January 2023 Chief of Engineers’ Command Philosophy Notice, USACE is aiming to achieve a goal of 70% BU by the year 2030 (HQUSACE 2023), hereinafter the Chief’s 70/30 goal.
  • Effects of Suspended Sediment on Aquatic Organisms: A Literature Review and Database Effort

    Abstract: The US Army Corps of Engineers (USACE) acknowledges that uncertainties and public perceptions regarding the effects of suspended sediment on aquatic organisms, particularly the concentration thresholds associated with harmful effects, present an ongoing challenge to its dredging mission. USACE is actively working to address these challenges through improved monitoring, research, and collaboration to support safer and more sustainable dredging practices. To help mitigate this uncertainty, 159 field- and laboratory-based studies describing the effects of sediment on aquatic organisms were reviewed and compiled in a database. No- and low-effect ecotoxicity data from this review were further analyzed to determine percentiles of effects data and species sensitivity distributions. The analysis indicated corals and freshwater crustaceans were most sensitive, followed by fish, while bivalves and marine crustaceans appeared to be the most tolerant of suspended sediment. This literature review provides a foundational framework for visualizing site-specific suspended sediment thresholds for effects concentrations associated with potential effects on aquatic species. It serves as a starting point for identifying critical data gaps for future research, layering in additional data, refining thresholds, and supporting more informed, site-specific decision-making moving forward.
