This Technical Report describes procedures for the packaging, preservation, short-term storage and transport of both solid and liquid waste samples, including paste-like substances and sludges. Where available and appropriate for field application, requirements for specific storage conditions and/or preservation methods should be selected from the chosen analytical standard and collaboration with the testing laboratory.
NOTE 1 This Technical Report provides a shop shelf of example sampling techniques that can be selected to meet a wide range of sampling situations. For a specific situation one of the presented procedures may be appropriate.
NOTE 2 The procedures listed in this Technical Report reflect current best practice, but these are not exhaustive and other procedures may be equally relevant.
