Solidification and stabilization (S/S) are treatment methods used to manage contaminated soil, sediment, sludge, and waste. Solidification helps contain contaminants by physically binding them into a solid material, while stabilization reduces the ability of contaminants to move or leach into the environment. Together, these methods are designed to reduce the amount of contamination that can reach groundwater or other environmental media.
The Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) guidance explains how to establish performance specifications to determine whether an solidification/stabilization remedy will effectively meet cleanup goals. It covers how to use treatability studies and testing to select treatment conditions, develop performance targets, and evaluate the effectiveness of treated material. The guidance also describes quality control testing during implementation and long-term monitoring to verify that the remedy continues to protect human health and the environment. In particular, it helps users understand how contaminant leaching test results can be used to evaluate the performance of a solidification/stabilization remedy over time.
