GES partners with government agencies—at the federal, state, and municipal levels—to help protect and enhance both natural and built resources. Our aim is to provide real-world stewardship through practical, effective, and sustainable solutions that balance our clients’ environmental objectives with their fiscal responsibilities.

Our approach yields efficiencies and lower costs to project stakeholders. Services may be provided at a single project location with highly focused requirements, or under multi-site task orders for ongoing tasks such as environmental field services and system operation and maintenance (O&M).

With more than a quarter-century of service, our experience ranges from the compliance, assessment, and investigation of contaminated soil and groundwater to rapid response, aggressive remediation, infrastructure management, and property restoration. GES has experience serving as prime contractor and as a member of multidisciplinary project teams. We are often called upon to provide our innovative remediation technologies to expedite site closure at some of the most challenging contaminated sites. We understand the critical importance of coordinating efforts with other contractors to achieve the desired results—on time and within budget.

GES supports supplier diversity and offers expanded procurement opportunities for historically disadvantaged firms. See our Partnering page to explore opportunities for working with GES.
