1、Designation:D690722Standard Practice forSampling Soils and Contaminated Media with Hand-Operated Bucket Augers1This standard is issued under the fixed designation D6907;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last
2、 revision.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 practice describes the procedures and equipmentused to collect surface and subsurface soil and contaminatedmedia samples
3、for chemical analysis using a hand-operatedbucket auger(sometimes referred to as a barrel auger).Severaltypes of bucket augers exist and are designed for samplingvarious types of soil.All bucket augers collect disturbedsamples.Bucket augers can also be used to auger to the desiredsampling depth and
4、then,using a core-type sampler,collect arelatively undisturbed sample suitable for chemical analysis.1.2 This practice does not cover the use of large 300 mm orgreater diameter bucket augers mechanically operated by largedrill rigs or similar equipment,such as those described inPractice D1452/D1452M
5、,paragraph 5.2.4.Practice D1452/D1452M on auger borings refers to this hand auger included inPractice D6907 as a barrel auger.1.3 Refer to Guides D4700 and D6232 for information onother hand samplers.The bucket auger is often used forshallow surface soil sampling,but there are many other typesof han
6、dheld augers,flight,screw,rotary powered,and agricul-tural push tube samplers.Practice D1452/D1452M addresseslarger powered solid stem flight auger systems.1.4 This standard does not address soil samples obtainedwith mechanical drilling,direct push,and sonic machines(refer to Guides D6286/D6286M and
7、 D6169/D6169M)or forcollecting cores from submerged sediments(Guide D4823).1.5 This practice does not address sampling objectives(seePractice D5792),general sample planning(see Guide D4687),and sampling design(for example,where to collect samplesand what depth to sample(see Guide D6044).Sampling for
8、volatile organic compounds(see Guide D4547),equipmentcleaning and decontamination(see Practice D5088),samplehandling after collection such as compositing and subsampling(see Guide D6051),and sample preservation(Guide D4220/D4220M)are used in this standard.1.6 UnitsThe values stated in SI units are t
