Abstract

Solidification/Stabilization (S/S) with binders is an established remedial approach to reduce the mobility of organic and inorganic contaminants and simultaneously improve the geotechnical properties of soils, sediments and a variety of waste materials.

This paper presents the results of a design treatability testing program for the S/S treatment of acid organic waste associated with the remediation and closure of four waste impoundment units at a former chemical manufacturing facility. S/S was selected as the most appropriate technique to improve the compressive strength and reduce the permeability of the waste and reduce the leachability of a complex suite of organic constituents of concern. A variety of mix design formulations were evaluated to implement a two-step treatment process consisting of a neutralization treatment of the acidic waste, followed by S/S treatment.
