  Technology Performance Review: Selecting and Using Solidification/Stabilization Treatment for Site Remediation (28 pp, 863 KB)
November 2009

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.

This TPR is not an authoritative or original source of research on S/S treatment and is intended to provide a summary of the S/S process and its potential applicability across multiple sites and conditions. This document should not be used as the sole basis for determining this technology’s applicability to a specific site.
