1.1 This guide addresses 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: 1.1.1 Stratigraphic description, 1.1.2 Hydraulic conductivity testing, 1.1.3 Moisture content measurement, 1.1.4 Moisture release curve construction, 1.1.5 Geotechnical testing, 1.1.6 Soil gas analyses, 1.1.7 Microorganism extraction, or 1.1.8 Pore liquid and soils chemical analyses. 1.2 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. 1.3 This guide does not describe sampling methods for lithified deposits and rocks (for example, sandstone, shale, tuff, granite). 1.4 In general, it is prudent to perform all field work with at least two people present. This increases safety and facilitates efficient data collection. 1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
