Environmental Remediation and Restoration

As an experienced remediation contractor SES will identify the most effective and appropriate remedial action technologies and activities to treat our clients’ contaminated sites. Or we can implement a pre-selected treatment option. Each site is unique but at SES we have the knowledge and expertise to recommend and implement the best strategy for varying site conditions.

We also perform interim remedial actions to prevent problems from getting worse before the investigative work is complete, at the same time dramatically reducing the final remediation cost. We are also experienced in preparing feasibility studies, corrective measures studies, and pilot and bench scale studies to evaluate and test appropriate remedial actions.

SES's experience with diverse remedial tasks includes:

  • Impermeable barrier construction
  • Soil removal
  • Groundwater pump and treat systems
  • Equipment and building decontamination
  • Beryllium dust removal
  • Waste management
  • Air sparging systems
  • Multi-phase vacuum extraction
  • Enhanced bioremediation using oxygen and hydrogen release compounds
  • Asbestos abatement

At SES we take pride in our work and we care about the environment. So it goes without saying that, upon completion of a project involving site disturbance, we carefully restore the area to its natural habitat by regrading, mulching, seeding and planting as necessary.

Featured Projects

SES performed a large monitoring project involving the delineation of groundwater contamination at this inactive wood-treating facility, an EPA Superfund site. In addition to installing 10 deep groundwater monitoring well clusters at depths of 19 to 250 feet, and quarterly groundwater sampling for one year, SES designed an on-site treatment system for the handling and disposal of all development, purge and decontaminated water.

Since 1998 SES has been involved in investigative and remedial efforts at Campbell Army Airfield (CAAF) where a complex fueling system originating from the 1950s has been the source of numerous leaks causing soil and groundwater contamination. Vacuum extraction continues to be an effective means of removing hydrocarbons from the environment and SES has conducted multi-phased vacuum extraction activities at the CAAF under multiple follow-on task orders using both fixed and mobile extraction systems. In six years we removed almost 182,000 equivalent gallons of vapor and free phase product at the site, and also provided operational support and wastewater sampling analysis and reporting.

SLURRY WALL CONSTRUCTION – Savannah National Wildlife Refuge, Georgia
As just one component of a $3.76 million contract to rehabilitate the existing freshwater control system of the Refuge, SES raised a canal levee to 12 feet and installed a 750 foot long grout slurry cut-off wall along a settled length of the levee to minimize leakage into adjacent property.
