Description:
This chapter discusses field sampling design for environmental sites and hazardous waste sites with respect to random variable sampling theory, Gy's sampling theory, and geostatistical (kriging) sampling theory. The literature often presents these sampling methods as an adversarial "either/or" philosphy; this chapter emphasizes when each should be used with a cooperative "both/and" philosophy. The intrasample variances, biases, or correlations must be taken care of by the use of Gy's sampling theory for both independent random variable sampling and analysis and correlated random variable sampling and analysis.The deciding factors in the choice of sampling design and analysis are not just intersample variances, biases, or correlations but also the discreteness of the waste under investigation, remediation as a unit, and the relative cost of samples versus the cost of remediation.
