Designation:D590396(Reapproved 2012)Standard Guide forPlanning and Preparing for a Groundwater Sampling Event1This standard is issued under the fixed designation D5903;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 guide covers planning and preparing for a ground-water sampling event.It includes technical and administrativeconsiderations and procedures.Example checklists are alsoprovided as Appendices.1.2 This guide may not cover every considerationprocedure,or both,that is necessary before all groundwatersampling projects.In karst or fractured rock terranes,it may beappropriate to collect groundwater samples from springs(seeGuide D5717).This guide focuses on sampling of groundwaterfrom monitoring wells;however,most of the guidance hereincan apply to the sampling of springs as well.1.3 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.1.4 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 orexperience and should be used 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 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:2D5717 Guide for Design of Ground-Water Monitoring Sys-tems in Karst and Fractured-Rock Aquifers(Withdrawn2005)33.Significance and Use3.1 The success of a sampling event is influenced byadequate planning and preparation.Use of this guide will helpthe groundwater sampler to methodically execute the planningand preparation.3.2 This guide should be used by a professional or techni-cian that has training or experience in groundwater sampling.4.Considerations and Procedures4.1 Evaluate the scope of the sampling and analysis pro-gram.4.1.1 Review plans,protocols,and objectives of the sam-pling program and event.The sampler should review thesampling and analysis plan,site health and safety plan,sampling protocol,and quality assurance/quality control plan,when available.These documents will provide information onrequired sampling procedures and also should provide theinformation in the following paragraphs.4.1.2 Determine which wells will be sampled.The samplershould have a map or diagram showing the locations of thewells to be sampled.Determine if there is a preferred wellsampling sequence specified in the sampling and analysis plan.4.1.3 Identify the laboratory analyses to be performed onsamples from each well.The analytical requirements are often,but not always,the same for each well.Determine if there is apreferred order in filling containers based on analytes.4.1.4 Identify data to be collected in the field.The samplermust know in advance what types of data must be collected inthe field(that is,chemical measurements,water levelmeasurements,etc.)Many samplers use a form to record fielddata and other observations.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 from 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 be1This guide is under the jurisdiction ofASTM Committee D18 on Soil and Rockand is the direct responsibility of Subcommittee D18.21 on Groundwater andVadose Zone Investigations.Current edition approved July 1,2012.Published November 2012.Originallyapproved in 1996.Last previous edition approved in 2006 as D5903 96(2006).DOI:10.1520/D5903-96R12.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 released to the ground surface,discharged to a sanitary orindustrial sewer,or containerized and handled as a potentiallyhazardous waste.Hazardous wastes will require specializedlabeling
