Abstract

A study was undertaken by Environment Canada (EC), in conjuction with the United States Environmental Protection Agency (USEPA), Alberta Environment, and 15 industrial participants involved in developing or marketing solidification technology, to develop and validate 16 laboratory test methods for evaluating the physical and chemical properties of solidified wastes. Environment Canada and USEPA provided the 15 industrial participants with 5 untreated hazardous wastes. The industrial participants applied their proprietary processes to the wastes and returned the solidified products to four laboratories in Canada and the United States for testing. Seven physical tests, five leaching tests, and four micromorphological characterization methods were applied to the solidified products. Although the reproducibilities of the different methods were found to range from excellent to only fair, this study showed that all of the methods were sufficiently reproducible to be valuable tools for evaluating the properties of a wide variety of solidified wastes. The results of this study show that the majority of solidified products are strong, durable materials of intermediate permeability that immobilize heavy metal contaminants effectively, while providing little containment of organic compounds. © 1990.
