Abstract
Three soil sampling techniques were tested on a surface mined reclamation study. Multiple systematic spoil samples were compared to random samples and a composite sample in terms of statistical reliability and cost effectiveness. Both random and composite sampling offer considerable cost savings over the systematic sampling. Random spoil sampling was twice as likely as composite spoil samples to characterize spoil differently than the systematic sample. Composite spoil samples are a cost effective and reliable technique for sampling surface-mined spoils.
