Composite Sampling for Site Characterization and Cleanup Evaluation,Environmental data are collected for making and/or defending certain decisions. Using data quality objectives (DQO) to plan new data collection activities helps assure that the right type and quality of information will be collected and that the analysis of the collected information will lead to efficient decisions.

Inference on Mean and Variance,rlier (see Chapter 1), sampling units may be selected from a finite population or from a bulk population. In the former case, the sampling units are defined and exist before sampling while in the latter case, the sampling units are created by the sampling process.

A Linear Model for Estimation with Composite Sample Data,of individual samples to drawing inference on population parameters, especially the population mean. The measurements can be either presence/absence or continuous. A common theme in all these chapters is the need to establish a relationship between individual sample values and composite sample values.

Introduction, the soil we tread on. It can be related to the health risk due to a municipal waste sit or a sewage treatment plant. It can be about the epidemic after heavy rains and floods, or about the residues of pesticides in groundwater. These and many other situations call for immediate attention from both

Classifying Individual Samples into One of Two Categories,yphilis. This method has since been applied to screening of pollutants (Schaeffer, 1982; Rajagopal and Williams,1989), testing for leaking containers (Sobel and Groll, 1959; Thomas et al, 1973), identifying faulty components using a flow test (Hwang, 1984), identifying active users in a communicatio

Identifying Extremely Large Observations, average value. Many of these problems also have an interest in extremely high contamination levels. A common experience is that compositing sample averages out the individual sample values and hence does not incur any loss of information on the population mean. However, compositing poses a serious
