by:AEEC based inReston, VIRGINIA (USA)
AEEC applies a wide array of modeling tools in order to effectively model site conditions. Our modeling experience includes finite differences, finite element, 2-D, 3-D, multiphase, vadose zone concentrations, biodegradation, transport, fate, and animation. Conceptual models are applied by integration into the underlying grid system. The model output is calibrated to determine ...
by:Fruits & Associates based inAcworth, GEORGIA (US) (USA)
The system lowers the water table around the well, exposing more of the formation. Contaminants in the newly exposed vadose zone are then accessible to vapor extraction. Once above ground, the extracted vapors or liquid-phase organics and ground water are separated and ...
by:Southwest Ground-water Consultants, Inc. (SGC) based inPhoenix, ARIZONA (USA)
SGC specializes in hydrogeology as it relates to the development of groundwater resources and the recharge and recovery of water through percolation ponds, vadose zone wells, and ASR wells. SGC’s expertise in characterization of the underlying aquifer and vadose zone through infiltration testing, borehole and well installation and testing, and groundwater ...
by:TRS Group, Inc. based inLongview, WASHINGTON (USA)
The heat propagates radially away from the pipes, evaporating the contaminants. Applying the flexible, patented heaters, TRS can achieve temperatures in the vadose zone and ex situ cells high enough to volatilize high boiling contaminants, including PAHs, PCBs, and PFAS. The FlexHeater remediation is effective in all types of soil and bedrock, typically achieving 99% or more ...

by:Environmental Remediation Contractor based inGroveport, OHIO (USA)
Soil Vapor Extraction (SVE) is an in-situ remediation technology for the physical treatment of volatile and semi-volatile contaminants in the vadose zone (unsaturated soils) (EPA, 2012). Soil Vapor Extraction is also referred to as in-situ soil venting or vacuum extraction. It is based on a mass transfer of contaminants from the solid and liquid phases into the gas phase. Vacuum ...
by:GeoSystems Analysis, Inc. based inTucson, ARIZONA (USA)
GSA has earned a leading reputation in designing and implementing monitoring systems and developing research programs to evaluate hydrologic and ecological processes. GSA has deployed and maintained instrumentation for long-term monitoring of climate, vadose zone flow and transport, surface water flow and quality, and groundwater elevation and quality. GSA’s monitoring ...

From conceptual design through construction services, DBS&A assists clients with water infrastructure needs. Based on our expertise in vadose zone processes, DBS&A has become a national leader in the design of managed aquifer recharge (MAR) systems and a pioneer in MAR in the Southwest, in ...
by:Telluric Remediation Management Ltd (TRM) based inIlkeston, UNITED KINGDOM
Soil Vapour Extraction (SVE) is an in-situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semi-volatile contaminants. Vertical extraction wells are typically used at depths of 1.5 metres or more; horizontal extraction wells (e.g. installed in trenches) can also be ...
by:Nichols Environmental (Canada) Ltd. based inEdmonton, ALBERTA (CANADA)
Soil Vapor Extraction (SVE) is an in-situ remedial technology which is used to apply a vacuum to the vadose (unsaturated) soil zone which has been impacted by contaminants. The technology allows for the controlled flow of air to remove volatile compounds from the soil. Because the technology involves the continuous flow or air through the soil, it will often promote in-situ ...
by:Erler & Kalinowski, Inc. (EKI) based inBurlingame, CALIFORNIA (USA)
Obtaining insight on how contaminants change and move in the environment may be important in distinguishing the party responsible for a release, judging if a significant potential for chemical exposure exists, or determining appropriate remedial actions. EKI is accomplished in fate and transport modeling of contaminants in the vadose zone, groundwater, surface water, and ...
by:GeoSystems Analysis, Inc. based inTucson, ARIZONA (USA)
GSA has extensive experience related to groundwater resources and managed aquifer recharge having conducted over 30 groundwater recharge projects in the western United States, with a total recharge capacity exceeding 500,000 acre-feet per annum. GSA also specializes in the design and installation of innovative vadose zone and groundwater characterization systems that have been ...
by:Erler & Kalinowski, Inc. (EKI) based inBurlingame, CALIFORNIA (USA)
We have developed conceptual site models and performed site investigations using approaches ranging from shallow soil vapor surveys to multi-depth wells to investigate deep vadose zones, as well as the collection of sub-slab vapor and indoor air samples in commercial and residential buildings. We have conducted assessments of potential for vapor intrusion and performance of human ...
by:Aztech Technologies Inc. based inBallston Spa, NEW YORK (USA)
After the contaminant partitions from the source and into “vapor” it travels through the pore spaces of vadose or unsaturated soil via diffusion or advection. If the vapor migrates into the radius of influence of an existing building, then typical building pressure differentials related to heating or cooling systems can draw the vapors into or below the structure ...
by:InSitu Remediation Services Limited (IRSL) based inBurlington, ONTARIO (CANADA)
Effectively removing volatile compounds from the vadose zone. Also called “in situ soil venting” or “vacuum extraction”, Soil Vapour Extraction systems reduce concentrations of volatile constituents absorbed into the subsurface by converting them from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gaseous phase, and then removing ...
