Effective management means safely and cost-efficiently managing environmental liabilities in accordance with site-specific exit strategies.

GES has the expertise and resources to manage a project from remedial selection, planning and design, through construction and commissioning, and throughout the effective operation, maintenance and monitoring (OM&M) stage to site closure and system decommissioning. We have extensive experience designing, constructing, and operating diverse systems for the remediation of environmental media including soil, groundwater, sediment, sludge, soil gas, and surface water.

Our hands-on technical expertise in the field - including the deployment of integrated engineering and technical field services teams - delivers significant cost-efficiencies and essential quality control. We work as a team to develop the most cost-effective and aggressive remedial approach to site cleanup by understanding the basic concepts of the contaminants involved including, mobility and degradation factors, risk analysis, and remediation technology applicability. 

GES continuously integrates new technologies with existing technologies to provide the most aggressive, yet cost-effective, approach to remediation. To foster innovation in remedial technologies, GES' Max-Ox group focuses on the research, development, and deployment of innovative technologies for enhanced feasibility testing and aggressive treatment of contaminated soil and groundwater, including our patented Max-Ox technologies. Visit to learn more about these specialty remediation services including chemical oxidation, green remediation, real-time feasibility testing, and reductive remediation.
