Designation:D535893(Reapproved 2014)Standard Practice forSampling with a Dipper or Pond Sampler1This standard is issued under the fixed designation D5358;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes the procedure and equipment fortaking surface samples of water or other liquids using a dipper.A pond sampler or dipper with extension handle allows theoperator to sample streams,ponds,waste pits,and lagoons asfar as 15 ft from the bank or other secure footing.The dipperis useful in filling a sample bottle without contaminating theoutside of the bottle.1.2 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 safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D4687 Guide for General Planning of Waste SamplingD5088 Practice for Decontamination of Field EquipmentUsed at Waste Sites2.2 Other Documents:EPA-600/2-80-018 Samplers and Sampling Procedures forHazardous Waste Streams3EPA-600/4-84-076 Characterization of Hazardous WasteSites-A Methods Manual:Volume II.Available SamplingMethods,Second Edition33.Summary of Practice3.1 The dipper is lowered into the liquid and lifted out whileavoiding splashing or otherwise disturbing the surface layer.The sample is then poured into a sample container.4.Significance and Use4.1 This practice is intended for use in the sampling ofsurface waters and other liquids.4.2 Dipper equipment is uncomplicated in construction,simple to use,and relatively easy to decontaminate;however,this practice will not provide accurate results with multiphaseliquids.4.3 This practice is to be used by personnel acquiringsamples.4.4 The dipper is best used to take a surface sample ofliquid.No attempt should be made to take subsurface sampleswith a dipper because mixing and dilution will occur as thedipper is brought to the surface.Subsurface layers must besampled using a device that can be closed prior to bringing itto the surface(for example,a COLIWASA,tube sampler,orbottle sampler).4.5 The dipper is not appropriate for sampling multiphaseliquids if quantitative characterization is needed.4.6 When volatile organic analysis(VOA)will beperformed,samples obtained with a dipper should be pouredinto an appropriate container(VOA vial)with minimal aircontact and agitation.4.7 This practice should be used in conjunction with GuideD4687,which covers sampling plans,safety,Quality Assur-ance(QA),preservation,decontamination,labeling,and chain-of-custody procedures,also Practice D5088,which coversdecontamination of field equipment used at waste sites.Otherdocuments pertinent to this practice are EPA-600/2-80-018 andEPA-600/4-84-076.5.Sampling Equipment5.1 Dippers may be fabricated as shown in Fig.1 and arealso available commercially(see Fig.2).Disposable dippersare convenient for use with hazardous materials.Dippersselected must be constructed of materials compatible with theliquid being sampled and with the tests or analyses to beperformed.Light weight and rigidity are important character-istics of the extension handle.1This practice is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.01.03 onSampling Equipment.Current edition approved May 1,2014.Published May 2014.Originallyapproved in 1993.Last previous edition approved in 2009 as D5358-93(2009).DOI:10.1520/D5358-93R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from Standardization Documents Order Desk,Bldg.4 Section D,700Robbins Ave.,Philadelphia,PA 19111-5094,Attn:NPODS.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Sample Containers6.1 Plastic,glass,or other nonreactive containers should beused.Refer to Guide D4687 for further information on con-tainers.7.Procedure7.1 Have sample containers ready for use.7.2 Assemble the dipper and,if desired,the extensionhandle for the pond sampler.7.3 Lower the dipper slowly into the liquid.The dippershould be on its side so that liquid runs into the containerwithout bubbling or swirling.Rotate the dipper so that the lipof the container is up,preventing the sample from running out.Lift the dipper from the liquid.7.4 Remove the cap from the sample container,and tilt thecontainer slightly.7.5 Pour the sample from the dipper down the inside of thesample container.Avoid splashing of the sample.7.6 Leave adequa
