| Solidification/Stabilization (S/S) is a widely used treatment technology to prevent migration and exposure of contaminants from a contaminated media (i.e. soil, sludge and sediment). Solidification refers to a process that binds a contaminated media with a reagent changing its physical properties. Stabilization refers to the process that involves a chemical reaction that reduces the leachability of a waste. S/S treatment and application is primarily used at hazardous waste sites. This Technology Performance Review (TPR) includes a discussion on several sites, and addresses important factors to consider in the selection of S/S treatment. Each S/S case study has a brief project description, regulatory status, S/S treatment process that includes binder materials used, and a summary of the performance data. Estimated treatment costs and maintenance activities are also included when available. Estimated costs must be adjusted for inflation and current material price increases. |
