DR 95140

Proposes a method for the preparation of leachates from liquid and solid wastes, sediments, sludges and soils for assessing the potential of inorganic and semivolatile organic materials from wastes to contaminate groundwater, in a variety of disposal-to-land scenarios. It deals only with the preparation of the leachate and does not describe procedures prior to sample submission to the laboratory for analysis or subsampling. The range of analyte compounds includes, but is not limited to, those compounds with a vapour pressure in the range 10(sup)-1 mm Hg to 10(sup)-7 mm Hg and with a boiling point greater than 150 degrees Celsius.
