Introduction
The performance of this method is validated in accordance with
internationally recognised procedures.
This procedure describes the procedures required to prepare
leachates of soils for subsequent analysis for a range of parameters.
Principle

and 'diluted' at a water:soil ratio of 10:1. The sample is then
agitated for a period of 24 hours. The leachate is then filtered and
set aside for analysis.
