| Long description: |
Guidance for Obtaining Representative Laboratory Analytical Subsamples from Particulate Laboratory Samples (EPA 600-R-03-027). This guidance was published by the EPA National
Risk Management Research Laboratory. It provides education and instruction for managing a potential weakness in environmental data quality for solid materials. Representative data are the foundation of correct decisions and effective remedial designs. This document shows how analytical subsampling is a crucial link for representative samples. It defines sample representativeness in terms of the population of interest to the decision, which may or may not be based on a bulk average. Examples show how careless subsampling can severely bias analytical results (November 2003, 156 pages).
