Standard Guide for Selection of Subsurface Soil and Rock Sampling Devices for Environmental and Geotechnical Investigations

Importancia y uso:

4.1 Direct observation of the subsurface by the collection of soil and rock samples is an essential part of investigation for geotechnical and environmental purposes. This guide provides information on the major types of soil and rock sampling devices to assist in selection of devices that are suitable for known site geologic conditions, and provide samples that meet project objectives. This guide should not be used as a substitute for consulting with professional experience in sampling soil or rock in similar formations before determining the best method and type of sampling.

4.2 This guide should be used in conjunction with Guide D6286 on drilling methods and sampling equipment, and diamond drilling Guide D2113. Drilling and sampler specific practices and guides listed throughout this guide are used as part of developing a detailed site investigation and sampling plan. The sampling plan should start with development of a site conceptual model and phased investigations to locate sampling sites (D420, D6286). The selection of sampling equipment and sampling devices goes hand-in-hand. In some cases, soil sample requirements may influence choice of drilling method, or conversely, types of available sampling equipment may influence choice of sampling devices.

4.3 Samples should be handled in accordance with Practice D4220/D4220M, for preserving and transporting soil samples, Practice D5079 for preserving and transporting rock core samples for geotechnical purposes. For environmental work sample handling procedures should be in accordance with Practice D6640 for collection and handling of soils obtained in core barrel samplers for environmental investigations, Practice D3694 for preparation of sample containers and for preservation of organic constituents, and Practice D5088 for decontamination of field equipment used at waste sites.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
