Description:
This article discusses the use of solidification/stabilization (S/S) to treat soils contaminated with organic and inorganic chemicals at wood preserving sites. Solidification is defined for this article as making a material into a free standing solid. Stabilization is defined as making the contaminants of concern non mobile as determined from a leaching test. SS then combines both properties. For more information on SS in general the reader should refer to other publications (Conner, 1990; USEPA 1993a: wiles, 1989) as this article addresses only wood preserving sites and assumes basic knowledge of SS processes. For a more general discussion of wood preserving sites and some other remedial options, the reader may wish to refer to a previous EPA publication (EPA, 1992a). This article includes data from the successful remediation of a site with mixed organic/inorganic contaminants, remediation of a site with organic contaminants, and detailed treatability study results from four sites for which successful formulations were developed. Included are pre and post treatment soil characteization data, site names, vendor names (in some cases), treatment formulas used (generic and proprietary), costs, recommendations and citations to more detailed references. The data presented indicate that Dioxins, pentachlorophenol, creosote polycyclic aromatic hydrocarbons (PAHs) and metals can be treated at moderate cost by the use of SS technology.
