Through our multidisciplinary and client-first approach to sustainable site remediation, Ramboll supports clients through the complexities of remedial decisions. Our experts develop innovative strategies that focus on risk management at all stages of the remediation lifecycle and understand the importance of quantifying uncertainty in decision making. We have established an unsurpassed reputation with public- and private-sector clients as well as regulators for achieving cost-effective site closure.

Ramboll is at the forefront of green and sustainable remediation, and our innovative thinking and turnkey solutions have been applied successfully to thousands of industrial, mining, development and hazardous waste sites around the world. Our tailored, innovative solutions address evolving industry drivers such as urbanization, climate change and resiliency and digitalization.

Site Investigation

Our tiered, risk-based approach ensures focused, cost-effective site investigations for soil, vapor, sediment, surface water, groundwater and building systems. We use state-of-the-art techniques to collect, interpret and manage site data, complementing our capabilities in fate and transport modeling and health risk assessment. This enables our investigators to not only evaluate the current status of site contamination, but also provide valuable input into the development of site-specific, risk-based remediation goals.

Site-Specific Risk Assessment

We draw on experts in the toxicological, biological and physical-chemical disciplines that underlie the risk and exposure assessment processes to apply innovative and scientifically defensible risk assessment and management to:

  • Optimize the scope of work and the associated costs for site investigations
  • Quickly and conservatively identify potential problem areas and provide early estimates of the nature and magnitude of challenges
  • Reduce unnecessary data collection
  • Focus efforts where the greatest gains in risk reduction can be achieved

Remedial Action

Ramboll's integrated and client-first approach to sustainable and resilient remedies guides our clients through the complexity of remedial decisions. Central to this approach are a willingness to pursue innovative strategies, an ability to model uncertain costs, and a focus on risk management at each step in the remediation lifecycle from evaluation to design and project delivery.

Remedy Optimization and Sustainable Solutions

Remediation strategies for site closure have undergone a significant paradigm shift. We use passive strategies such as in situ bioremediation, chemical oxidation and chemical reduction remediation tools coupled with remedy optimization strategies and innovative diagnostic tools to facilitate rapid site closure.

Decommissioning and Demolition

We work with clients to manage decommissioning sites to mitigate risks to the environment, while also attaining the best value for the facility, equipment and the land itself. We assist with tender document preparation, supervision of decommissioning work and preparation of supporting information to achieve regulatory closure.

Emerging Contaminants

Leading the industry in treatment and remediation solutions for clients with sites potentially impacted by emerging contaminants, including PFAS, forefront and microplastics, Ramboll asseses risk data developed by state and federal regulators and helps clients adapt to and effectively manage potential risks.

Net Environmental Benefit Analysis (NEBA)

Our experts use NEBA, which demonstrates whether the detrimental impacts of the remedy outweigh the benefits for each alternative considered, to carefully examine all factors and alternatives when determining an optimal path forward. Learn more about Ramboll’s NEBA and ecological services.

Brownfield Redevelopment

We develop cost-effective, risk-based approaches for the evaluation, remediation and redevelopment of landfills and former industrial/hazardous waste facilities to return the land to productive use and provide long-term economic and socioeconomic benefits for our clients and the community. We work with site developers to find the optimum approach to managing soil and groundwater risks in the context of the proposed land use and negotiate these integrated risk management strategies with regulatory agencies. 

Project Delivery

We assist in the preparation of specifications and plans, manage the bidding process, negotiate and administer contracts, schedule construction, supervise implementation onsite and assure compliance with specifications, budget and schedule. We provide these services in a traditional construction management role, in the role of designer/builder and/or through turnkey delivery of an entire project. 

Expert Services

Ramboll provides consulting services, expert testimony, strategic advice and technical litigation support. We have worked on many seminal environmental, toxic tort and product liability cases and recognize the importance of well-reasoned expert opinions based on defensible science, rigorous analysis, and comprehensive understanding of environmental practice, policy and regulation

All engineering services on projects in North Carolina are provided by an associated entity, REUS Engineers, P.C.

Indiana Harbor and Canal

Strategic sediment management to restore a Great Lakes waterway

The removal of nearly 1 million cubic yards of sediment from the Indiana Harbor and Canal is helping to restore the waterway to navigable depths and improve water quality in southern Lake Michigan.

Progress toward restoring value of Fountain Lake

Removal of more than 1 million cubic yards of sediment will reduce the lake’s internal phosphorus load and increase the water depth – ultimately maximizing water clarity and water quality throughout the watershed

In situ technology results in significant time savings

Ramboll, in partnership with its client and regulatory officials, developed a remedial strategy for a site in Teterboro, New Jersey, USA using in situ thermal remediation for the areas of greatest contamination, combined with in situ chemical oxidation for the less contaminated zones, and a slurry wall to surround 3.2 acres of the parcel.
