Soil Vapor Extraction | Technology Description
Soil Vapor Extraction (SVE) is an in situ remediation technology designed to remediate soils impacted with volatile organic compounds (VOCs) including gasoline, and chloroethenes. This technology works by extracting soil vapor at a high vacuum using subsurface wells, then treating the soil vapor prior to discharge.

Dual-Phase Extraction (DPE) | Technology Description
Dual-Phase Extraction (DPE) is a remediation technology used to remediate soils and groundwater affected with volatile organic compounds (VOCs). This technology works by extracting soil vapor and groundwater from the subsurface, then treating the vapors and water prior to discharge.

Air Sparge | Technology Description
Air sparge is an in situ groundwater remediation technology were air is injected into the groundwater to increase dissolved oxygen. Air sparge is used to remediate impacted groundwater with volatile organic compounds (VOCs), most commonly gasoline range organics.

Advanced Oxidation using Ultraviolet Light and Hydrogen Peroxide
Advanced oxidation systems using hydrogen peroxide (peroxide) and ultraviolet (UV) light are designed to inject hydrogen peroxide in controlled ratios to the water, then mixing the peroxide, and exposing the water and peroxide solution to UV radiation to form hydroxyl radicals (•OH). Peroxide and hydroxyl radicals are strong oxidizing agents capable of oxidizing 1,4-dioxane and…

Ion Exchange Systems for Removal of Metals and Inorganics
Description Ion Exchange is a process in which ions of a species are displaced from an insoluble exchange material (ion exchange resin) by ions of a different species in water. The removal of target ions is achieved through commercially available ion exchange resins that exchange target anions for chlorine (Cl-) or hydroxide ion (-OH), and…
