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