Principles and use of solidification/stabilization treatment for organic hazardous constituents in soil, sediment, and waste
- Portland Cement Association, Skokie, IL (United States)
Solidification/stabilization (S/S) treatment involves mixing a binding reagent into contaminated media or waste. S/S treatment protects human health and the environment by immobilizing hazardous constituents within the treated material. S/S has been effective in treating a large variety of hazardous constituents in many different forms of waste and contaminated media. The U.S. Environmental Protection Agency (EPA) has identified S/S as Best Demonstrated Available Treatment Technology (BDAT) for at least 50 commonly produced industrial hazardous wastes. EPA has selected S/S treatment for over 20% of its Superfund site source control remediation projects. Much of the published literature and actual treatment project experience has to do with treatment of inorganic hazardous constituents including radioactive materials. Radioactive wastes and environmental contaminants are often mixtures of inorganic and organic hazardous constituents. In recent years S/S is increasingly being used to address soil and sediment contaminated with organic hazardous constituents. Many of these remediation projects include polycyclic aromatic hydrocarbons (PAH) or polychlorinated biphenyls (PCB). The paper and presentation will discuss the chemical and physical mechanisms that can immobilize inorganic and organic hazardous constituents within S/S-treated material. The paper will also discuss examples of recent full-scale projects where S/S has been used to successfully treat organic hazardous constituent contaminated soil and sediment both in-situ and on excavated material.
