Remediation, Restoration and Redevelopment

Effectively and safely addressing contaminated sites is vital to on-going business activities and to the overall health of our communities and the environment. In all regions of the world and for a variety of industry and government clients, AECOM solves complex challenges with our remediation, restoration and redevelopment services, tackling a broad array of contaminants and working cooperatively with diverse stakeholder groups.

At AECOM, our approach is to carefully consider site-specific conditions, regulatory requirements, stakeholder issues and the best possible outcome for each site. Our work has resulted in many success stories where clients have recovered the value tied up in impaired property and where we have helped generate goodwill in affected communities by creating an asset.

Our comprehensive site restoration and reuse solutions maximize in-situ technologies and integrate key remedial design elements with future site redevelopment plans. To ensure ecosystem viability, we use scientific, proven and defensible methods to guide our strategies for risk reduction.
