(Guide)Standard Guide for Selection of Drilling and Direct Push Methods for Geotechnical and Environmental Subsurface Site Characterization
Standard Guide for Selection of Drilling and Direct Push Methods for Geotechnical and Environmental Subsurface Site Characterization
SIGNIFICANCE AND USE
4.1 The 1998 edition of this standard was written solely for selection of drilling methods for environmental applications and specifically for installation of groundwater monitoring wells. The second revision was made to include geotechnical applications since many of the advantages, disadvantages, and limitations discussed extensively throughout this document also apply to geotechnical design use such as data collection (sampling and in-situ testing) for construction design and instrumentation. Besides installation of monitoring wells (D5092, D6724/D6724M), Environmental investigations are also made for sampling, in-situ testing, and installation of aquifer testing boreholes (D4044/D4044M, D4050).
4.2 There are other guides for geotechnical investigations addressing drilling methods such as in Eurocode (1, 2)5, U.S. Federal Highway Administration, (3, 4), U.S. Army Corps of Engineers, (5), and U.S. Bureau of Reclamation (6, 7). An authoritative Handbook on Environmental Site Characterization and Ground-Water Monitoring was compiled by Nielsen (8) which addresses drilling methods in detail including the advent of Direct Push methods developed for environmental investigations. Two other major drilling guides have been written by the National Drilling Association (9) and from the Australia Drilling Industry Training Committee (10) and these guides are user for the drillers.
4.3 Table 1 lists sixteen classes of methods addressed in this guide. The selection of particular method(s) for drilling/push boring requires that specific characteristics of each site be considered. This guide is intended to make the user aware of some of the various drilling/push boring methods available and the applications, advantages, and disadvantages of each with respect to determining geotechnical and environmental exploration. (A) Actual achievable drilled depths will vary depending on the ambient geohydrologic conditions existing at the site and size of drilling/push boring equipmen...
SCOPE
1.1 This guide provides descriptions of various methods for site characterization along with advantages and disadvantages associated with each method discussed. This guide is intended to aid in the selection of drilling method(s) for geotechnical and environmental soil and rock borings for sampling, testing, and installation of wells, or other instrumentation. It does not address drilling for foundation improvement, drinking water wells, or special horizontal drilling techniques for utilities.
1.2 This guide cannot address all possible subsurface conditions that may occur such as, geologic, topographic, climatic, or anthropogenic. Site evaluation for engineering, design, and construction purposes is addressed in Guide D420. Soil and rock sampling in drill holes is addressed in Guide D6169. Pertinent guides and practices addressing specific drilling methods, equipment, and procedures are listed in Section 2. Guide D5730 provides information on most all aspects of environmental site characterization.
1.3 The values stated in either SI units or inch-pound units (given in brackets) are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.4 This guide does not purport to comprehensively address all methods and the issues associated with drilling for geotechnical and environmental purposes. Users should seek qualified professionals for decisions as to the proper equipment and methods that would be most successful for their site investigation. Other methods may be available for these methods and qualified professionals should have flexibility to exercise judgment as to possible alternatives not covered in this guide. The guide is current at the time of issue, but new alternative methods may become available prior to revi...

1. Scope*
1.1 This guide provides descriptions of various drilling methods for environmental site characterization along with advantages
and disadvantages associated with each method discussed. A comprehensive description of these drilling methods can be found in
individual ASTM standards, see Section 2. This guide is intended to aid in the selection of drilling method(s) for geotechnical and
environmental soil and rock borings and the installation of monitoring wells and other water-quality monitoring devices.for
sampling, testing, and installation of wells, or other instrumentation. It does not address drilling for foundation improvement,
drinking water wells, or special horizontal drilling techniques for utilities.
1.2 This guide does not address methods of well construction, well development, or well completion. These topics are covered
in other ASTM documents, see Section 2.
1.2 This guide cannot address all possible subsurface conditions that may occur such as, geologic, topographic, climatic, or
anthropogenic. Site evaluation for engineering, design, and construction purposes is addressed in Guide D420. Soil and rock
sampling in drill holes is addressed in Guide D6169. Pertinent guides and practices addressing specific drilling methods,
equipment, and procedures are listed in Section 2. Guide D5730 provides information on most all aspects of environmental site
characterization.
1.3 The values stated in either SI units or inch-pound units (given in brackets) are to be regarded separately as the standard.
Because dimensions of materials used in the drilling industry are given in inch-pound units by convention, rationalized inch-pound
units also are used in this guide. Each system of units is to be regarded separately as standard. The values stated in each system
may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two
systems may result in nonconformance with the standard.
1.5 This guide does not specifically address methods of lithologic sample collection, such as coring, that may require the use
of a specific drilling method. Other ASTM guides should be consulted for sampling methods (see Guide D6169) and equipment
necessary for specific projects.
1.4 This guide does not purport to comprehensively address all of the methods and the issues associated with drilling for
geotechnical and environmental purposes. Users should seek qualified professionals for decisions as to the proper equipment and
methods that would be most successful for their site investigation. Other methods may be available for drilling these methods and
qualified professionals should have flexibility to exercise judgment as to possible alternatives not covered in this guide. The guide
is current at the time of issue, but new alternative methods may become available prior to revisions; therefore,revisions. Therefore,
users should consult with manufacturers or producers prior to specifying program requirements.
1.5 Pertinent guides addressing specific drilling methods, equipment and procedures are listed in This standard does not
purport to address all 2.1. A comprehensive list of guides, methods, practices, and terminology for drilling is contained in Guide
of the safety concerns, if any, associated D5730. Other documents covering procedures for environmental site investigations with

practices and determine the applicability of regulatory limitations prior to use.
