The solidification/stabilization (S/S) technology has become a proven, cost-effective method for the treatment and/or immobilization of hazardous wastes and contaminated soils and sludges. The success of any S/S project is dependent on the individual success in the following three general areas: proper selection of reagent and proportions; the use of applicable field equipment and procedures; and, the implementation of proper quality assurance/quality control (QA/QC) and field sampling and testing procedures.
This paper evaluates several solidification/stabilization methodologies, discusses their advantages and limitations, and provides a general overview of the solidification/stabilization process including: initial bench-scale testing; full-scale implementation; and, field sampling and analysis.
