    aquifers; aquifer tests; control wells; hydraulic conductivity; observation wells; specific capacity; storage coefficient; transmissivity; unconfined aquifers;

    Rationale

    This standard was last revised 6 years ago and is now overdue. This standard was balloted prior on D18.21 (19-01) and received a negative regarding this being a practice rather than a test method. The standard has been revised to a standard practice to address this negative.
