Designation:D404396(Reapproved 2010)1Standard Guide forSelection of Aquifer Test Method in Determining HydraulicProperties by Well Techniques1This standard is issued under the fixed designation D4043;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.1NOTEThe units statement in 1.2 was revised editorially in September 2010.1.Scope1.1 This guide covers an integral part of a series ofstandards that are being prepared on the in situ determinationof hydraulic properties of aquifer systems by single-ormultiple-well tests.This guide provides guidance for develop-ment of a conceptual model of a field site and selection of ananalytical test method for determination of hydraulic proper-ties.This guide does not establish a fixed procedure fordetermination of hydrologic properties.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 LimitationsWell techniques have limitations in thedetermination of hydraulic properties of groundwater flowsystems.These limitations are related primarily to the simpli-fying assumptions that are implicit in each test method.Theresponse of an aquifer system to stress is not unique;therefore,the system must be known sufficiently to select the properanalytical method.1.4 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.1.5 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:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD4044 Test Method for(Field Procedure)for InstantaneousChange in Head(Slug)Tests for Determining HydraulicProperties of AquifersD4050 Test Method for(Field Procedure)for Withdrawaland Injection Well Testing for Determining HydraulicProperties of Aquifer SystemsD4104 Test Method(Analytical Procedure)for DeterminingTransmissivity of Nonleaky Confined Aquifers by Over-damped Well Response to Instantaneous Change in Head(Slug Tests)D4105 Test Method for(Analytical Procedure)for Deter-mining Transmissivity and Storage Coefficient of Non-leaky Confined Aquifers by the Modified Theis Nonequi-librium MethodD4106 Test Method for(Analytical Procedure)for Deter-mining Transmissivity and Storage Coefficient of Non-leaky Confined Aquifers by the Theis NonequilibriumMethodD4630 Test Method for Determining Transmissivity andStorage Coefficient of Low-Permeability Rocks by In SituMeasurements Using the Constant Head Injection TestD4631 Test Method for Determining Transmissivity andStorativity of Low Permeability Rocks by In Situ Mea-surements Using Pressure Pulse TechniqueD5269 Test Method for Determining Transmissivity of Non-leaky Confined Aquifers by the Theis Recovery MethodD5270 Test Method for Determining Transmissivity and1This 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 Aug.1,2010.Published September 2010.Originallyapproved in 1991.Last previous edition approved in 2004 as D404396(2004).DOI:10.1520/D4043-96(2010)E01.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Storage Coefficient of Bounded,Nonleaky,ConfinedAquifersD5472 Test Method for Determining Specific Capacity andEstimating Transmissivity at the Control WellD5473 Test Method for(Analytical Procedure for)Analyz-ing the Effects of Partial Penetration of Control Well andDetermining the Horizontal and Vertical Hydraulic Con-ductivity in a Nonleaky Confined AquiferD5716 Test Method for Measuring the Rate of Well Dis-charge by Circular Orifice WeirD5785 Test Method for(Analytical Procedure)for
