1、Designation:D628612Standard Guide forSelection of Drilling Methods for Environmental SiteCharacterization1This standard is issued under the fixed designation D6286;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revi
2、sion.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This guide provides descriptions of various drillingmethods for environmental site characterization along withadvantages and disadv
3、antages associated with each methoddiscussed.A comprehensive description of these drilling meth-ods can be found in individualASTM standards,see Section 2.This guide is intended to aid in the selection of drillingmethod(s)for environmental soil and rock borings and theinstallation of monitoring well
4、s and other water-quality moni-toring devices.1.2 This guide does not address methods of wellconstruction,well development,or well completion.Thesetopics are covered in other ASTM documents,see Section 2.1.3 This guide cannot address all possible subsurface con-ditions that may occur such as,geologi
5、c,topographic,climatic,or anthropogenic.Site evaluation for engineering,design,andconstruction purposes is addressed in Guide D420.1.4 The values stated in SI units are to be regarded as thestandard.Because dimensions of materials used in the drillingindustry are given in inch-pound units by convent
6、ion,rational-ized inch-pound units also are used in this guide.Each systemof units is to be regarded separately as standard.1.5 This guide does not specifically address methods oflithologic sample collection,such as coring,that may requirethe use of a specific drilling method.Other ASTM guidesshould
7、 be consulted for sampling methods(see Guide D6169)and equipment necessary for specific projects.1.6 This guide does not purport to comprehensively addressall of the methods and the issues associated with drilling forenvironmental purposes.Users should seek qualified profes-sionals for decisions as
8、to the proper equipment and methodsthat would be most successful for their site investigation.Othermethods may be available for drilling and qualified profession-als should have flexibility to exercise judgment as to possiblealternatives not covered in this guide.The guide is current atthe time of i
9、ssue,but new alternative methods may becomeavailable prior to revisions;therefore,users should consultwith manufacturers or producers prior to specifying programrequirements.1.7 Pertinent guides addressing specific drilling methods,equipment and procedures are listed in 2.1.A comprehensivelist of gu
10、ides,methods,practices,and terminology for drillingis contained in Guide D5730.Other documents coveringprocedures for environmental site investigations with specificobjectives or in particular geographic settings may be availablefrom federal,state,and other agencies or organizations.Theappropriate a
11、gency or organization should be contacted todetermine the availability and most current edition of suchdocuments.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safet
12、y and health practices and determine the applica-bility of regulatory limitations prior to use.1.9 This guide offers an organized collection of informationor a series of options and does not recommend a specificcourse of action.This document cannot replace education andexperience and should be used
13、in conjunction with professionaljudgment.Not all aspects of this guide may be applicable in allcircumstances.This ASTM standard is not intended to repre-sent or replace the standard of care by which the adequacy ofa given professional service must be judged,nor should thisdocument be applied without
14、 consideration of a projects manyunique aspects.The word“Standard”in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.2.Referenced Documents2.1 ASTM Standards:2D420 Guide to Site Characterization for Engineering Design1This guide is under the
