In situ chemical treatment methods

Table 16.7 and Table 16.8 summarize some promising in situ chemical treatment methods for organics and inorganics that can be applied to soil. Some of them can also be applied to groundwater. 

Summary of In Situ Chemical Treatment Methods for Organics... 

Surfactant washing is among the most promising in situ chemical treatment methods. Surfactants can improve the solvent property of the flushing water, emulsify nonsoluble organics, and enhance the removal of hydrophobic organics sorbed onto soil particles.
