Solidification/Stabilization Training Course

ITRC Documents Associated with this Topic

The Solidification/Stabilization (S/S) training course supports the use of S/S technologies for the on-site treatment of contaminated soil, sediment, sludge, and waste. S/S remedies are designed to reduce the flux of contamination that leaches from a contaminant source to within acceptable parameters set forth in a site-specific remediation goal.

Solidification/Stabilization: Development of Performance Specifications for Solidification/Stabilization

Solidification/Stabilization (S/S) is a remedial technology option which blends treatment reagents into contaminated material to impart physical and/or chemical changes to reduce the flux of contamination that leaches from a contaminant source to within acceptable parameters set forth in a site-specific remediation goal. S/S can be effective for metals, asbestos, radioactive materials, oxidizers, PAHs, PCBs, and pesticides and is potentially effective for dioxins/furans, some VOCs and other organics. Although there is abundant literature describing the S/S process and test methods for design and implementation, there was a lack of guidance for assessing performance. The ITRC technical and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach developed by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance specifications and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing an appropriate degree of treatment and regulatory confidence in the performance data to support decision making. This training and guidance is intended to be beneficial to anyone involved with CERCLA, RCRA, brownfields, UST, or any other regulatory program where S/S has been selected or implemented as a remedial technology.
