ASTM WK24706

    New Guide for Selection of Passive Technologies for Sampling Ground Water Monitoring Wells

    (What is a Work Item?)

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


    1. Scope

    1.1 This standard provides guidance and information on passive, i.e., no-purge, techniques for sampling ground water monitoring wells to be used for water quality studies. These techniques do not require purging the well prior to sample collection and do not use a pump during sample collection. 1.2 Other methods for sampling monitoring wells include low flow methods D 6771 and traditional well volume purging methods. Consult standards D 5903 and D6089 for planning and documenting sampling. Ground water samples my require preservation (D6517), filtration (D6564), and measures to pack and ship samples (D6911). Follow standard D 7069 to assure quality control and assurance of the sampling event.

    Passive and No Purge technologies are gaining acceptance and use is increasing


    Ground Water Sampling, Passive sampling, No Purge Sampling

    The title and scope are in draft form and are under development within this ASTM Committee.
