1.1 This guide covers procedures that may be used for obtaining soil samples from the vadose zone (unsaturated zone). Samples can be collected for a variety of reasons including the following:...
1.1.9 Laboratory chemical analysis identifying contaminant types and concentrations within soils.
1.2 Guides D6169 on Selection of Soil and Rock Sampling Devices and D6282 on Drilling methods for Environmental Site Characterization provide subsequent supplemental information to the contents of this standard.
1.3 This guide focuses on methods that provide soil samples for chemical analyses of the soil or contained liquids or contaminants. However, comments on how methods may be modified for other objectives are included.
1.4 This guide does not describe sampling methods for lithified deposits and rocks (for example, sandstone, shale, tuff, granite).
1.5 In general, it is prudent to perform all field work with at least two people present. This increases safety and facilitates efficient data collection.
