There are a number of critical parameters to be considered for the application of in situ soil flushing, including the hydrogeological conditions of the contaminated site, the type and properties of contaminants, the properties of the additives, and the treatability of the flushing solution.76 80...

The pump-and-treat method is comparable to soil flushing. In fact, the pump-and-treat method can treat both groundwater and aquifer soil at the same time, and can also be directly applied to unsaturated soil zones. The soil flushing method is mainly considered as a treatment in unsaturated zones.

For in situ soil flushing, large volumes of water, at times supplemented with surfactants, cosolvents, or treatment compounds, are applied to the soil or injected into the groundwater to raise the water table into the contaminated soil zone. Injected water and treatment agents are isolated within the underlying aquifer and recovered together with flushed contaminants.50-52,85... 

There are various agents that can be used to wash soil and drive its contaminants out, as discussed in the section on in situ soil flushing technology. 

The excavated soil is removed from the site and screened to remove large solid objects. The screened soil is washed and the washing water is treated.78 Clearly, the washing media used in in situ soil-flushing treatment can be used here. The most common washing medium is water. Surfactants are used to reduce the affinity of contaminants to the soil. 

The remedial technologies83-85,90-93 described in previous sections for gasoline release are applicable, for the most part, for remediation of DNAPLs. For example, the pumping or trench method for free products, vacuum extraction, biodegradation, pumping and treatment, soil flushing, and soil excavation and treatment are suitable for cleanup of various phases of DNAPLs. Again, because of...

The vacuum-vaporized well technology is a proprietary process that combines vacuum extraction, bioremediation, and soil flushing to mobilize contaminants in the vadose, capillary, and saturated zones. A schematic of the double-screened well with the equipment contained within is shown in Figure 10.12. 

Soil flushing is a commercially available, in situ technology for the treatment of soils contaminated with inorganic compounds including radioactive contaminants. The technology can also be used to treat volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs),...
