AS 4439.2:2019 PDF
This Standard provides a method for the preparation of leachates using zero headspace conditions, from liquid and solid wastes, sediments, sludges and soils for assessing the potential of volatile organic contamination of groundwater in a variety of disposal-to-land scenarios.
This Standard was prepared by the Standards Australia Committee CH-035, Examination of Wastes, to supersede AS 4439.2—1997.
The objective of this Standard is to provide a standardized method to determine the contamination potential of groundwater with volatile, organic materials from liquid and solid wastes, soils, sediments and sludges.
The major changes in this edition are as follows:
(a) Option to use AS 4439.2 for potentially volatile Hydrogen Cyanide forming Cyanide species.
(b) Additional information on use of this method for Per- and Polyfluoroalkyl Substances (PFAS).
(c) Additional options for determination of percentage solids.
(d) Modified reporting requirements.
