Contaminated sites present challenges that require long-term solutions. Delineation and quantification of contamination, containment, treatment, and prevention are activities we perform on a regular basis. From sampling and diagnosis of contamination, to analysis of regulatory issues, to development and implemention of cost-effective remedial solutions, SES will help you attain the ultimate goal of a clean site requiring No Further Action. 

SES professionals have been designing and implementing environmental solutions since 1992 and we have the experience, the technical knowledge and the proven capability to get the job done.

Permitting

SES has prepared hundreds of permitting documents throughout our company’s history and, having worked in almost every state across the country as well as in several overseas locations, we are experienced in preparing and complying with varied federal, state, local and international regulations. Permits we typically prepare include: 

• NPDES Storm Water Permits
• Monitoring Well Permits
• Injection Well Permits
• Building Permits
• Waste Water Discharge Permits
• Utility Clearance Permits
• Wetlands Permits

• SOIL REMEDIATION AND GROUNDWATER MONITORING. At Hunter Army Airfield, Georgia, SES excavated a zone of contaminated soil from the former pumphouse site, an old aviation-gas fuel island that had once housed ten 25,000-gallon USTs. Tasks included: excavating and stockpiling the uncontaminated soil; removing the contaminated soil; applying Oxygen Release Compound® (ORC®) to the excavation floor and four side walls; backfilling the excavation site; re-installing three groundwater monitoring wells that were within the excavation area; and conducting groundwater monitoring at the site.


• SLURRY WALL CONSTRUCTION:  As one component of a $3.76 million project to rehabilitate the existing freshwater control system of the Savannah National Wildlife Refuge, SES raised a canal levee and installed a 750 foot long slurry wall, to a depth of 12 feet below finished grade, along a settled length of the levee to minimize leakage into an adjacent property.
