Samples are collected and examined primarily to determine their physical,
chemical, biological, and radiological properties. This section outlines the
more important factors which should be considered when devising a sampling program for soil and related material. More detailed information is
given in subsequent sections.
Whenever a volume of soil is to be characterized, it is generally not possible to examine the whole and it is therefore necessary to take samples.
The samples collected should be as fully representative as possible, and all
precautions should be taken to ensure that, as far as possible, the samples
do not undergo any changes in the interval between sampling and examination. The sampling of multiphase systems, such as soils containing water
or other liquids, gases, biological material, radionuclides, or other solids
not naturally belonging to soil (e.g., waste materials), can present special
problems. In addition, the determination of some physical soil parameters
may require so-called undisturbed soil samples for correct execution of the
relevant measurement ………..
