Sediment Remediation
Cleanup And Restoration Of Complex Waterways
We led the feasibility study, design, construction, and O&M for the Onondaga Lake Superfund Site in New York and continue to provide long-term monitoring services to ensure the remedy is functioning as intended. Our work at Onondaga Lake is helping revitalize what was once called the “most polluted lake in the United States” and turning it into a recreational hub for the local community.
We have decades of experience investigating and remediating contaminated sediment sites and restoring damaged natural resources. We were the driving force for two of the largest sediment remediation projects completed to-date in the United States at the Onondaga Lake and Hudson River Superfund Sites. We have also worked on numerous other sediment sites including Cherry Farm, Geddes Brook/Ninemile Creek, Berry’s Creek, and Lower Genesee River.
Contaminated sediment sites pose complex regulatory, financial, legal, logistical, and technical challenges – and Parsons’ multidisciplinary team is equipped to support our clients from initial investigation to final remediation and site closure. Our sediment experts have extensive boots-on-the-barge investigation, design, and construction experience, providing a thorough understanding of the remediation process for multiple federal, state, and local regulatory frameworks that leads to practical and cost-effective solutions through every phase of the project.
Our sediment investigation and remediation services include:
We led the feasibility study, design, construction and O&M for the Onondaga Lake Superfund Project in New York, one of the most complex sediment sites ever remediated.
Sediment remediation projects pose complex regulatory, financial, legal, logistical, and technical challenges – and our interdisciplinary team is ready to support from initial investigation to final remediation and site closure. By beginning every project with the end in mind, we successfully achieve client and regulatory goals efficiently and effectively.
Our experts employ a customized total solutions approach to each project, developing and implementing closure strategies based on intelligent investigations, human health and ecotoxicology studies, and risk assessments – while maintaining the highest levels of safety and cost-effectiveness.
Our sediment remediation and management services include:
Site Characterization
From custom-built porewater passive samplers and sediment sampling in challenging environments to extensive habitat surveys and biota sampling, Parsons has done it all. Beyond our proven site investigation capabilities, our site characterization expertise involves a wide range of services including human health and ecological risk assessments; contaminant nature and extent evaluations; fate and transport modeling and assessments; and NAPL mobility evaluations in rivers, lakes, and estuaries. Our emerging contaminants experts are actively engaged in developing solutions for remediating per- and polyfluoroalkyl substances (PFAS) in anticipation of sediment regulations for these ‘forever chemicals’.

Treatability Studies
The state-of-the-art Parsons treatability laboratory in Syracuse, New York can perform treatability studies to support dredged material stabilization/solidification, sediment dewatering and water treatment, cap amendment material testing, in situ solidification/stabilization (ISS) testing, and innovative technology development for our sediment remediation projects. Our treatability laboratory also conducts self-funded, internal research and development to better prepare us for the next frontier in sediment remediation, such as PFAS.
Remedy Selection And Design
team of sediment experts have extensive experience with a variety of remedial technologies including dredging, capping, in situ treatment (including ISS), monitored natural recovery (MNR), and enhanced MNR working under all types of federal, state, and local regulatory frameworks. This allows us to develop implementable and cost-effective remedies that meet or exceed client, regulatory, and stakeholder goals. We have completed numerous feasibility studies with extensive remedial technology screening and alternatives evaluations, remedial action objectives and cleanup goal development, and detailed cost analyses. Our multidisciplinary design teams can provide detailed design services for all remedial technologies mentioned above including geostatistical contaminant delineation, dredge prism design, chemical isolation modeling and design for amended and unamended caps, sediment dewatering and treatment design, beneficial use, and habitat restoration design.
Construction And Construction Management
We extensive experience with sediment remedy construction services, including self-performed construction and construction management and oversight. We provide a full suite of construction services including construction verification and QA/QC; dredged material treatment, handling, and transport; implementation of engineering controls such as sheet pile walls and turbidity curtains; procurement of skilled labor from local unions and communities with environmental justice concerns; odor, emissions, and water quality monitoring during construction; and closeout reporting.
Long-term Monitoring And Maintenance
Our sediment experts can develop and implement cost-effective, technically robust programs for baseline and long-term monitoring to evaluate achievement of remedial goals and habitat restoration metrics. Our monitoring programs are developed with site closure in mind and often include multimedia sampling and surveying techniques.
