Samenvatting:
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
