16、pile and physically removing a sample. In-placeevaluations include techniques such as remote sensing, on-sitegas analysis, and permeability.4.3 Sampling strategy for waste piles is dependent on thefollowing:4.3.1 Project objectives including acceptable levels of errorwhen making decisions;4.3.2 Phys

17、ical characteristics of the pile, such as its size andconfiguration, access to all parts of it, and the stability of thepile;4.3.3 Process that generated the waste and the waste char-acteristics, such as hazardous chemical or physical properties,whether the waste consists of sludges, dry powders or

18、granules,and the heterogeneity of the wastes;4.3.4 History of the pile, including dates of generation,methods of handling and transport, and current managementmethods;4.3.5 Regulatory considerations, such as regulatory classi-fication and characterization data;4.3.6 Limits and bias of sampling metho

19、ds, including biasthat may be introduced by waste heterogeneity, samplingdesign, and sampling equipment.4.4 It is recommended that this guide be used in conjunctionwith Guide D 4687, which addresses sampling design, qualityassurance, general sampling considerations, preservation andcontainerization,

20、 cleaning equipment, packaging, and chain ofcustody.4.5 A case history of the investigation of a waste pile isincluded in Appendix X1.5. Site Evaluation5.1 Site evaluations are performed to assist in designing themost appropriate sampling strategy. An evaluation may consistof on-site surveys and ins

21、pections, as well as a review ofhistorical data. Nonintrusive geophysical and remote sensingmethods are particularly useful at this stage of the investigation(see Guide D 5518). Table 1 summarizes the effects thatvarious factors associated with the waste pile, such as thehistory of how the pile was

22、generated, have upon the strategyand design of the sampling plan. The strategic and designconsiderations are discussed as well.5.2 Generation HistoryThe waste pile may have beencreated over an extended time period.Aremote sensing methodthat is very useful in establishing historical managementpractic

23、es for waste piles is aerial imagery. Aerial photographsare widely available and may be used to determine the historyof a waste pile, sources of waste, and the presence anddistribution of different strata. Satellite imagery could be usedfor larger waste piles.5.2.1 The date of generation could be im

24、portant with respectto the types of processes that generated the waste, the charac-teristics of the waste, the distribution of the constituents, andregulatory concerns.5.2.2 The type of process that generated the waste willdetermine the types of constituents that may be present in thewaste pile. Che

25、mical variability will influence the number ofsamples that are required to characterize the waste pile unlessa directed (biased) sampling approach is acceptable.5.2.3 The delivery method of the material to the waste pilecould influence the concentrations of the constituents, affectthe overall shape

26、of the pile, or create physical dissimilaritywithin the waste pile through sorting by particle size or density.5.2.4 If the pile is under current management and use, thevariability in constituent types and concentrations may beaffected. Current management activities also may influence theregulatory

27、status of the waste pile.5.2.5 Regulatory considerations will typically focus onwaste identification questions, in other words is the material asolid waste that should be regulated and managed as ahazardous waste (1).3This may involve a limited, directedsampling approach, particularly if a regulator

28、y agency isconducting the investigation. A more comprehensive samplingdesign may be required to determine if the waste classifies ashazardous. Remediation efforts and questions regarding per-mits may focus on characterizing the entire pile, possibly as theremoval of material is occurring. It should

29、be noted thatconcentrations of contaminants near regulatory levels mayincrease the number of samples required to meet the objectivesof the investigation. These regulatory levels could be thoseestablished to determine if a waste is hazardous, or “cleanup”levels set for a removal or remediation.5.3 Ph

30、ysical Characteristics of Pile Several physicalcharacteristics of the waste pile must be considered during thesite evaluation. Variability in size, shape, and stability of thepile affects access to it to obtain samples as well as safetyconsiderations. Physical variability will influence the numberof

31、 samples that are required to characterize the waste pileunless a directed (biased) sampling approach is considered tobe acceptable. Techniques that might be used include resistivityand seismic refraction (for determining the depth of very largepiles).5.3.1 The size of the waste pile will influence

32、the samplingstrategy in that increasing size is often accompanied byincreased variability in the physical characteristics of the wastepile. The number of samples, however, that are needed to3The boldface numbers in parentheses refer to the list of references at the end ofthis standard.TABLE 1 Strate

36、e,and if it is topologically complex it is difficult to lay out asampling grid. Also, a waste pile may extend vertically bothabove and below grade, making decisions regarding the depthof sample collection difficult.5.3.3 The stability of the waste pile also can limit access toboth the face and the i

37、nterior of the pile. The use of certaintypes of heavier sampling equipment also could be limited bythe ability of the pile to bear the weight of the equipment.5.4 Waste Characteristics:5.4.1 The constituents could include inorganics, volatileorganic compounds (VOCs), and semivolatile organic com-pou

38、nds (including pesticides and polychlorinated biphenyls(PCBs) (see Practice D 4547). Speciality analyses may bewarranted, such as leaching tests or analyses for dioxin/furansor explosive compounds. Soil gas sampling is a minimallyintrusive technique that may detect the presence and distribu-tion of

39、volatile organic compounds in soils and in porous,unconsolidated materials. Appropriate applications for soil gasmonitoring are identified in Guide D 5314.5.4.2 The distribution of constituents in the waste pile couldbe influenced by changes in the manufacturing process whichresulted in changes in t

40、he composition of the waste; the lengthof time the material has remained in the pile (particularly forVOCs); the mode of delivery of the waste materials to the pile;and management practices, such as mixing together wastesfrom more than one process.5.4.3 Physical and chemical variabilities would incl

41、udevariability in the chemical characteristics of the material withinthe pile, as well as variability in particle size, density, hardness,whether brittle or flexible, moisture content, consolidated, orunconsolidated. The variability may be random or found asstrata of materials having different prope

42、rties or containingdifferent types or concentrations of constituents.5.4.3.1 Geophysical survey methods may be used on piles toestimate physical homogeneity, which may or may not berelated to chemical homogeneity, and to detect buried objects,both of which may need to be considered during the develo

43、p-ment of the sampling design and the safety plan for theinvestigation. The most suitable technique for detecting non-metallic objects is electromagnetics. Ground-penetrating radar,a more sophisticated and complex technique, also may beconsidered. Electromagnetic techniques are suited particularlyto

44、 large piles that contain leachate plumes (for example, minetailings) or for the detection of large discontinuities in a pile(for example, different types of wastes or the transition from adisposal area to background soils). For metallic objects, metaldetectors and magnetometers are useful and relat

45、ively easy touse in the field.5.5 Potential Investigation Errors:5.5.1 Equipment selection can bias sampling results even ifthe equipment is used properly. Bias can result from theincompatibility of the materials that the sampling equipment ismade of with the materials being sampled. For example, th

46、eequipment could alter the characteristics of the sample. Someequipment will bias against the collection of certain particlessizes, and some equipment cannot penetrate the waste pileadequately.5.5.2 Equipment, use, and operation can introduce error(bias) into the characterization of a waste pile. Sa

47、mpling errorstypically are caused when certain particle sizes are excluded,when a segment of the waste pile is not sampled, or when alocation outside the pile is inadvertently sampled.5.5.3 When stratification, layering, or solid phasing occursit may be necessary to obtain and analyze samples of eac

48、h ofthe distinct phases separately to minimize sampling bias. Careshould be taken when sampling stratified layers to minimizecross contamination. Proper decontamination proceduresshould be used for all sampling equipment (see PracticeD 5088).5.5.4 Statistical bias includes situations where the data

49、arenot normally distributed or when the sampling strategy doesnot allow the potential for every portion of the pile to besampled.6. Sampling Strategy6.1 Developing a strategy for sampling a waste pile requiresa thorough examination of the site evaluation factors listed inSection 5. The location and frequency of sampling (number ofsamples) should be outlined clearly in the sampling plan, aswell as provisions for the use of special sampling equipment,access of heavy equipment to all areas of the pile, if necessary,and so forth.6.1.1 Representative SamplingThe collection o
