Abstract

Representative environmental data are necessary to make defensible environmental decisions. Representative data can be obtained using unbiased sampling designs developed in the context of the project to achieve sampling objectives with required confidence and minimal cost. This article stresses the importance of systematic planning and an adequate conceptual site model to develop an appropriate sampling design. Various sampling designs are discussed and examples are used to illustrate sampling designs for various sampling objectives.
