The nature of the medium between locations can only be inferred. Second, once sample locations for groundwater are set they cannot be moved. Only additional wells can be installed. Thirdly, the most important parameter in groundwater investigations, the velocity is rarely measured directly.

Tools showing extensive surface abrasion should be replaced or used only for preliminary excavations. ! Thomas E. Barnard 40 Authors of sampling plans need to be aware of the subsampling and processing that samples undergo prior to the measurement of the desired parameter. While not always explicitly stated most soil sample designs involve either the compositing or multi level sampling at some point. Laboratory procedures almost always require some subsampling prior to analysis. A typical mass of a soil sample is 500 gm while a typical aliquot for chemical analysis may be 5-50 mg.

Extensive field decontamination procedures with solutions of acid or organic solvents are generally not recommended.
