Sampling and analysis presents specific problems with heterogeneous soils. These problems have been carefully evaluated in several projects for the Risk Reduction Engineering Laboratory (RREL), specifically Superfund Innovative Technology Evaluation (SITE) demonstrations. Of particular concern is the inability of standard analytical methods to account for heterogeneous samples. While a typical analytical method may normally accommodate only 2 grams (g) of sample (and therefore requires that {open_quotes}oversized material{close_quotes} be removed from a sample before analysis, potentially biasing analytical results), a representative sample aliquot from a heterogeneous site may require a sample size that is orders of magnitude greater than this. This paper contains several case studies that present the problems associated with sampling and analyzing heterogeneous soils; approaches to specific problems encountered in each of the projects discussed; and the relative success of these approaches.
