Sediment Remediation

Unrivaled Sediment Management Experience 

Onondaga Lake
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.

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.

Many of our specialists have boots-on-the-barge investigation, design, and construction experience, providing a thorough understanding of the remediation process that leads to practical and cost-effective solutions through every phase of the project (ex. Onondaga Lake Cleanup – Syracuse, NY)

Water Treatment And Reuse  

A Clear Choice For Water 

As a full-service partner in implementing conventional and advanced water and wastewater treatment technologies, we help solve water management challenges with innovative, custom solutions. Our mission is to help preserve water – our most critical resource – by creating and maintaining safe, efficient, and sustainable water facilities and processes. Our expertise in program and construction management (PM/CM) and engineering have helped us transform the industry through some of the most complex water and wastewater projects in the world.

Treatment Facility
We designed a combined biological, physical, and chemical treatment plant for groundwater and landfill leachate at a superfund site in Virginia.

Conventional And Advanced Technologies

Our world-class water and wastewater services include:

Water Resources

Our expertise involves a wide range of services, from availability studies to National Pollutant Discharge Elimination System (NPDES) permitting, wetlands delineation, and coastal restoration


Covering all aspects of storage, treatment, conveyance, and membrane treatment systems, including desalination, we deliver innovative solutions to meet our clients’ needs.

Wastewater And Water Reuse

Clean water is essential, and we help keep it that way through sewers, pump stations, and wastewater treatment plants, as well as a range of advanced processes in liquid and biosolids treatment and handling.

Industrial Wastewater

Industry produces wastewater, and our job is to ensure that it’s handled correctly, and without harming the environment. From engineering and construction services to detailed design and construction management, we offer state-of-the-art technology and solutions to the oil and gas, chemical, petrochemical, manufacturing, and life-science industries.
