In-Situ Cleaning of CHC Contaminated Sites: Model-Scale Experiments Using the Air Injection (In-Situ Stripping) Method in Granular Soils
Chapter
Abstract
The cleaning method of air injection (also known as in-situ stripping), combined with the technique of vapour extraction is regarded as a promising new method for cleaning groundwater contaminated by volatile substances (e.g. CHC). In the initial stage of this cleaning process compressed air is injected into the groundwater area. The air rises in the pores of the soil up to the unsaturated zone, thus transferring the contaminants from the solved or adsorbed phase to the vapour phase. The mobilized contaminants can then be captured by the parallel process of vapour extraction.
