Sediment Assessment & Remediation

The assessment and remediation of sediment involves a complex mixture of multi-disciplinary technical tools, effective project management, and strong regulatory advocacy.

It also requires a robust conceptualization of conditions and an understanding of geochemistry and biological functions and uptake. The key is recognizing the problem before defining the remedy and ensuring that the science is used to inform decision making.

Realistic, Practical Solutions

At EHS Support our focus is on making rational and practical assessment and remediation decisions that provide real solutions. We understand the inherent uncertainties and are willing to go the extra mile to define the significance. At the same time, we are realistic and set practical goals that can be achieved in an industrialized waterway. Our experts provide an unbiased application, balancing criteria and select alternatives that reflect the practicality of application and their effectiveness in mitigating risks.

A Dedicated and Knowledgeable Team

EHS Support’s Sediment Assessment and Remediation team has a reputation for its laser focus and the willingness to explore, advocate, and drive to better outcomes. Our experts have worked on a variety of contaminants and emerging contaminants in estuarine, harbor, lake, and river systems. Bringing together specialists in engineering, ecology and biological sciences, risk assessment and applied toxicology, and earth sciences, we have the necessary breadth and depth of capacity to deliver on any project.

An energetic team that’s focused on delivering the right outcomes for clients — that’s EHS Support.

Investigation Design & Implementation

Investigation Design & Implementation

Designing and implementing efficient sediment investigation programs that reduce uncertainty and allow for confident decision making requires a robust conceptual site model and clear data-quality objectives. Specialized equipment, collection techniques, and field strategies are a must. Our comprehensive services include both low- and high-resolution core sampling, thermal imaging surveys, bioavailability assessments, pore water sampling, biological tissue sampling, and sediment quality triad (SQT) studies.

Remedy Selection, Design, & Implementation

Remedy Selection, Design, & Implementation

We understand that defining goals based on chemistry, bioavailability, and site-specific risks to relevant receptors is critical to successful, cost-effective sediment remediation. That’s why our scientists and engineers are focused on developing site-specific, risk-based criteria that can be integrated into practical, protective, and appropriately scaled remedial strategies that lead to regulatory closure.

Source Identification & Allocation

Source Identification & Allocation

For multi-party sites, it’s vital to allocate costs and develop a position of advocacy. This is especially true at sediment mega-sites, where investigation, remediation, oversight, and natural resource damage costs can be high. Early involvement in the investigation and assessment program can impact future assessments, so strategies must be developed early and evolve. Our experts understand this and develop scientifically robust and compelling arguments for source identification and allocation.
