Contaminated soil and groundwater remediation can stop a project cold. Investigations can be costly. No two sites are alike. We use a risk-based approach coupled with regulatory advocacy to safely bring fragile, damaged sites back into compliance without compromising human health or the environment. For complex real estate transactions and industrial landowners, we offer fixed-price remediation solutions through TerraSure.
We’ve spent the last 40 years leading the recovery of thousands of impacted sites throughout the world. When active remediation is needed, our engineers use an alternatives analysis process to determine the technology best suited for the site conditions and constraints. We develop management strategies that protect resources and maintain compliance with regulations, while allowing you to stay focused on your business.
And, when you work with us, you’ll benefit from having a single point of contact to guide you successfully through the No Further Action letter process with regulatory authorities.

Five Steps to Managing Contaminated Sites
Our Five-Step Impacted Site Management Approach
1. AssessmentOur first step in managing a contaminated site is to understand the nature and extent of the contamination and the regulatory requirements of state and local jurisdictions. Hydrogeological studies, soil boring investigations, soil vapor studies, and human health and ecological risk assessments are vital inputs for the design, construction, and implementation phases that follow.
2. Remedial DesignWhen remediation design is required, our engineers apply a systematic alternatives analysis, which typically includes a pilot study and may include modeling and lifecycle cost estimates.
3. ConstructionExecution of the selected technology typically includes permitting, selection, and management of specialized contractors stakeout, shop drawing review, construction management and inspection, scheduling, and all site requirements to ensure a careful and controlled delivery of the project.
4. Operation and Maintenance (O&M)When mechanical systems are constructed, we provide system start-up and shake-down, O&M manual preparation, collection, and interpretation of system performance data and on-site O&M. And, we regularly evaluate data trends and make adjustments to ensure maximum uptime and performance.
5. MonitoringResults monitoring and reporting provides the evidence needed to obtain a No Further Action or Remedy Complete letter.
