Finally, one must decide between obtaining discrete (grab) or composite samples. A. Lewandowski samples involve combining individual discrete samples, mixing them thoroughly, and taking a representative sample of the combined material. Data for discrete samples have the advantage of being traceable to a particular location but also have the disadvantage of providing coverage for only a very limited area. Thus, many discrete samples may be required to characterize the extent of contamination in a large geographical area or determine whether the area is uncontaminated.

Another potential negative of random sampling is that, depending on the combination of random numbers generated, the sampling pattern can look rather counterintuitive and clumped (Fig. 3). While statistically valid, such a pattern can be difficult to explain to individuals unfamiliar with statistical theory. 2 Designing Good Sampling Plans for Characterizing Pesticide Pollution 33 Fig. 4 Stratified Sampling Stratified sampling combines several of the best features of the prior three approaches.
