Description:
The purpose of this document is to provide assistance in deciding in situ treatment of contaminated soils is a potentially feasible remedial alternative. echnical considerations that affect the decision to treat soils in situ are discussed. eneral factors which influence the selection of in situ treatment are hydrogeologic flow regime, regulatory standards, time available for remediation, removal logistics, and waste conditions. he document also provides information relevant to reviewing and screening in situ technologies. actors important to the following in situ technologies are discussed: solidification/stabilization, soil vapor extraction, bioremediation, bioventing, vitrification, radio frequency heating, soil flushing, and steam injection and extraction. ystems for delivery and recovery of liquids, vapors, and energy to and from the subsurface are included.
