Featured Projects

RESERVOIR OXYGEN DIFFUSER - Modoc, South Carolina
SES engineered and installed equipment and intrumentation to interface with the Government's new cryogenic oxygen storage system and to mitigate potential thermal impacts of this operation on the fishery resources of the J. Strom Thurmond Lake.

SOIL REMEDIATION AND GROUNDWATER MONITORING - 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® 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.

SITE INVESTIGATION OF SMALL ARMS RANGE BERM AREA - Fort Stewart, Georgia
SES delineated the full extent of contamination in multiple media (sediment, soil, groundwater and surface water). Approximately 1,050 tons of contaminated soil was identified and removed from the berm.

DEMOLITION POND STUDY - Fort Bragg, North Carolina
We designed a flow control structure to provide peak flow reduction and short-term storage for runoff to improve water quality by reducing sediment traveling downstream.
