1. Scope

1.1 This guide covers how casing-advancement drilling and sampling procedures may be used for geoenvironmental exploration and installation of subsurface water-quality monitoring devices.

1.2 Different methods exist to advance casing for geoenvironmental exploration. Selection of a particular method should be made on the basis of geologic conditions at the site. This guide does not include procedures for wireline rotary casing advancer systems which are addressed in Guide D5786.

1.3 The values stated in inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only.

1.4 Casing-advancement drilling methods for geoenvironmental exploration and monitoring-device installations will often involve safety planning, administration and documentation. This guide does not purport to specifically address exploration and site safety.

1.5 This standard does not purport to address all of the safety concerns, 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.

1.6 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word "Standard" in the title of this document means only that the document has been approved through the ASTM consensus process.
