Air Sparging Service
Air Sparging, also known as in-situ air stripping and in-situ volatilization, is an in-situ remediation technology used for the treatment of saturated soil zones and groundwater contaminated with volatile organic compounds (VOCs). This technique involves the injection of pressurized air into contaminated groundwater enabling the hydrocarbons to change its state from dissolved to vapor state. The injection of air helps to flush the contaminants upward into the unsaturated zone where a vapor extraction system is typically implemented to remove the volatilized contaminants. This technology has beneficial side effects like adding dissolved oxygen to the contaminated groundwater and unsaturated zone soils. This enhances the biodegradation of contaminants below and above the water table.
