GES Takes Home Project Merit Award

01/29/2007

The Environmental Business Journal recently announced the winners of their 2006 Business Achievement awards. GES won the Project Merit Award for deploying an innovative remediation approach while allowing development to proceed at one of the world’s largest brownfields redevelopment sites.

GES was contracted by a government-owned hotel corporation in a Caribbean island nation to provide environmental assessment and remediation services in support of the cleanup and redevelopment project. Managed through GES’ Innovative Remedial Solutions Program (IRSP), the project is being implemented in three phases to coordinate with the construction of a new $2-billion resort area. GES is remediating a nine-acre LNAPL plume resulting from a release of over 30,000 gallons of diesel fuel. The remediation system was designed to aggressively remediate 37% of the plume in the first nine months of operation to facilitate the resort’s development. Site-specific cleanup standards were developed based on future residential use of the property and included risk-based soil, water, and product cleanup values as well as a product mobility analysis. The innovative remediation system consists of in situ chemical oxidation via ozone injection and eight large recovery/re-injection trenches to re-circulate up to 2,000 gallons of water and surfactant. Large slurry or containment walls prevent the migration of contaminants from untreated areas into completed locations. An advanced remote monitoring system allows engineers in Pennsylvania to monitor and adjust system equipment to optimize system performance.
