    Revision of D5270 - 96(2014) Standard Test Method for Determining Transmissivity and Storage Coefficient of Bounded, Nonleaky, Confined Aquifers

    (What is a Work Item?)

    Developed by Subcommittee: D18.21 | Committee D18 | Contact Staff Manager



    aquifer boundaries; aquifer tests; aquifers; confined aquifers; control wells; groundwater; hydraulic properties; image wells; observation wells; storage coefficient; transmissivity;


    This standard was last approved in 2014 and is now in its 5th year. In preparation for balloting, minor revisions were made to update the standard to current D18 procedures and policies. This procedure takes data from other test methods and uses calculational techniques determine transmissivity and storage coefficients. Since no field data is taken by this standard, it is more appropriate to make it a Standard Practice. The standard was also upgraded to current D18 policies and procedures.
