Abstract
Comparisons of alternate spatial sampling strategies for characterizing hazardous waste sites can be performed using GIS-based stochastic simulation techniques. This work compares a traditional sampling design that uses only precise laboratory analytical methods to a sequential screening strategy that uses field screening methods to focus quantitative analysis on areas having pollutant concentrations above the analytical detection limit. Cost savings that result from eliminating uncontaminated areas from detailed analysis are spent on obtaining additional measurements until a fixed sampling budget is depleted. The screening strategy produces less biased and more precise estimates of volatile organic compounds emissions from an example landfill.
