1、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
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.Scope1.1 This guide covers planning and preparing for a ground-water sampling event.It includes technical and administrativeconsideration
3、s 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
4、 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 thi
5、s 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 e

10、sampling 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 wi
11、ll 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 req
12、uirements 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,wat
13、er 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
