Laboratory Investigation of Organic Contaminant Immobilization by Proprietary Processing of Basin F Liquid, Rocky Mountain Arsenal, Denver, Colorado

摘要

The applicability of a proprietary solidification/stabilization process to liquid from a hazardous waste lagoon at the Rocky Mountain Arsenal, Denver, Colo., was investigated in laboratory studies. The proprietary process is cement based and is commercially available from Hazcon, Inc., Houston, Tex. The effectiveness of the Hazcon process for solidification of Basin F liquid was evaluated using an unconfined compressive strength test; its effectiveness for chemical stabilization of the organic content of the liquid was evaluated using batch leaching tests. The potential for ammonia release was also assessed by measuring ammonia gas concentrations in laboratory air during processing. The study was not designed to provide an evaluation of the capabilities of the Hazcon process for hazardous wastes in general.
