Abstract:
Testing for evaluation of contaminant release from soils and wastes isnecessary to compare management options and project potential environmental impacts. Frequently, the available management options include disposal as either an untreated or treated granular or monolithic waste form with varying extents of water contact. In addition, some wastes may be suitable for utilization as fill material or aggregate replacements in construction applications. Selection amongst these options requires substantially more intensive leaching testing and evaluation than is provided in most regulatory frameworks. Ideal testing and evaluation protocols would permit the necessary comparisons, provide realistic estimates of contaminant release under the scenarios evaluated, and be accomplished through use of a minimum number of analyses carried out over a very short time interval. A series of testing protocols has been under development for granular and monolithic wastes. The goal has been a series of tests that can be carried out in less than approximately one week with approximately six samples for chemical analysis that provide measurement of fundamental leaching parameters. These fundamental parameters then are used to estimate contaminant release under different management scenarios. Substantial reductions in testing requirements can be achieved through integration of the individual test methods. This paper will present the testing evaluation framework, using data obtained from several wastes to illustrate the benefits of the framework. 26 refs.
