The use of a form can help thesampler to collect and record information in a consistentmanner and can reduce the chance of failure to collect neededdata.4.1.5 Determine fro
19、m what depth range within the well thesamples will be collected.4.1.6 Evaluate the need for specialized handling of purgedwater and decontamination wastewater. The waters may bereleased to the ground surface, discharged to a sanitary orindustrial sewer, or containerized and handled as a potentiallyh
20、azardous waste. Hazardous wastes will require specializedlabeling, storage, transportation, and disposal.4.1.7 Identify all documentation and field quality controlprocedures stipulated in the sampling and analysis plan orquality control plan.4.2 Review available information.4.2.1 Review well constru
21、ction details. The sampler shouldknow the material of construction, the inside diameter, thecompletion depth, the screened interval, and the cap type andlock type (if locked). This information is needed to selectpurging and sampling equipment, and may be needed to selectother tools (for example, a s
22、trap wrench to remove the cap,boltcutters or a hack saw to remove damaged locks, or keys forlocks).4.2.2 Evaluate historical well performance and chemicalcharacteristics of the water from each well, if available. Thebehavior of the well during past sampling events is usefulinformation in the plannin
23、g process. This may include the flowrate in the screened interval, the maximum pumping rate, thetime required to purge the well, whether the well is easilybailed or pumped dry, etc. Knowledge of the past groundwaterchemistry and non-aqueous phase liquids in the well also canbe useful. The turbidity
24、of the water may influence samplingmethods and the need for or approach to filtration of samples.Use of personal protective equipment also may be dictated byknown contamination of the water from a well.4.2.3 Evaluate the physical setting of the well locations.This is necessary to determine the acces
25、sibility of the wells.Access could be impeded or difficult due to mud, snow, trees,fences, steep hills, secured areas, etc. This information willhelp the sampler determine what type of vehicle is needed,whether special tools are needed, or whether administrativeclearances are required, or both.4.2.4
26、 For wells with dedicated sampling equipment find outthe type of equipment, pump depth, whether there are anypackers in the well, where packers are set, and the powersource for equipment.4.3 Estimate the time required to complete the samplecollection and associated field work. The amount of timerequ
27、ired will affect equipment needs and possibly lodging orother administrative arrangements. Evaluate the appropriatenumber of persons needed to sample the site. It is usuallynecessary to inform the laboratory when samples should arriveat the laboratory.4.4 Coordinate with the analytical laboratory.4.
28、4.1 Notify the laboratory in advance of the number ofanalyses of each type to include quality control sampleanalyses. This notification allows the laboratory to plan foradequate equipment and personnel resources to complete theanalyses.4.4.2 Determine the volume of sample needed for eachanalysis.4.4
29、.3 Coordinate the preparation or shipment, or both, ofsample containers, preservatives, and shipping containers tothe site and to the laboratory. The analytical laboratory oftensupplies the sample containers and preservatives, and some-times the shipping containers for the return of samples. Theproj
30、ect manager or sampler will need to provide the detailsneeded to accomplish this. The laboratory will need to knowthe number of containers and preservatives for each analyte,when the containers are needed, whether containers will bepicked up or shipped, and the address of the location to whichcontai
31、ners/preservatives must be shipped. The laboratoryshould specify any related administrative requirements. Thereturn of samples to the laboratory also must be coordinated.The sampler will need to be aware of any special instructionsregarding shipment or receipt of the samples (that is, timeswhen samp
32、les cannot be received, unacceptable shippingcontainers, Department of Transportation restrictions, anddocumentation requirements). The sampler also must have theaddress of the laboratory if samples will be shipped.4.4.4 When the sampler is also the project manager, themethods of analyses and lower
33、reporting limits also must becoordinated with the laboratory. These are chosen based on thedata quality objectives.4.4.5 Identify the sample volumes, preparation, and holdingtime requirements. The sampler should be aware of the totalvolume of water that must be collected from each well. Thismay infl
34、uence the selection of sampling equipment. Thesampler also should know what will be involved in thepreparation of samples (that is, chemical and physical preser-vation). This knowledge is needed to make logistical arrange-ments. For example, the sampler may need to use an area nearthe site that has
35、an electrical outlet and a sink if filtration isrequired. Lastly, the sampler must know if any of the sampleshave a short holding time (maximum allowable time betweensample collection and preparation or analysis). Collectingsamples with short holding times could influence the timing ormethod of samp
36、le shipment.4.4.6 Inform the laboratory of any special requirements thatare different than normal laboratory procedures.4.4.7 Notify the laboratory of the types and numbers of fieldquality control samples that will be submitted. Some qualitycontrol samples will be prepared or collected in the field;
37、 otherswill be prepared in the laboratory. The sampler must know howto collect and prepare the field quality control samples.4.4.8 Identify laboratory documentation needs. The labora-tory may have certain project identifiers, sample identifiers, orforms that they use for sample tracking or data repo
38、rting, orboth. It is important that the sampler and the laboratory agreeon all means of documentation that will be used by thelaboratory.D5903 96 (2017)124.4.9 Determine when the laboratory must be notified re-garding sample arrival times and how accurate the timeestimates must be (that is, within a
39、 day, a half a day, a week).The sampler should discuss this notification process with thelaboratory.4.4.10 Provide information to the laboratory on when dataare needed. This is the responsibility of the project manager;however, the sampler and the project manager may be the sameperson.4.5 Coordinate
40、 with the client or site-related personnel.Coordination with the client is necessary when sampling at asite not owned by you or your company. It also may benecessary to coordinate with people at your own site if theyshould be notified or have some involvement in your project.4.5.1 Notify the client
41、or site workers, or both, of when thesampling event will take place.4.5.2 Request logistical support as needed. This may be assimple as requesting use of the phone. In some cases, logisticalsupport needs may be more extensive. Other logistical supportitems could include an area for sample preparatio
42、n and storage,a potable water source, a vehicle, fuel, maintenance support,traffic control, tools, etc. The sampler should ensure that allsupport needed from outside sources is prearranged.4.5.3 Obtain necessary site and well access. It may benecessary to get a pass to enter a site or to have a perm
43、it tosample the wells. It also may be necessary to obtain keys togates or wells, or both. All possible access restrictions shouldbe identified in advance to prevent a delay in the samplingevent.4.5.4 Address site-specific safety concerns. This informa-tion should be available in a site health and sa
44、fety plan. If nosuch plan exists, at a minimum the sampler should obtainemergency phone numbers and a map showing the location ofthe nearest health care facility, and identify any safety hazardsor weather conditions unique to the site.4.6 Identify equipment needs. This identification will in-clude s
45、electing purging and sampling devices; field measure-ment equipment; sample handling, filtration, preservation, andshipping supplies; documentation; personal protectiveequipment, and other incidental equipment. Appendix X1 is anexample checklist of supplies and equipment. Using a compre-hensive chec
46、klist will reduce the chance of overlooking aneeded item.4.7 Make provisions to keep sample containers separatedfrom potential sources of contamination such as decontamina-tion reagents and fuel.4.8 Prepare sampling equipment and supplies for use. It isimportant that sampling equipment be in good op
47、eratingcondition before going into the field. The sampler should packnecessary and contingency supplies. Appendix X2 is an ex-ample checklist.4.9 Prepare field measurement equipment for use. Thesampler should check all field measurement devices to ensurethat they are operational. This should include
48、 calibration of testinstruments.4.10 Make lodging and transportation arrangements if nec-essary.5.
