Leachate Method Field

For all versions of the DLH, metal analyses performed on the original sample matrix (NO LEACHATE) are entered as: follows:

*the EXMCODEs "METHOD" and "SW3005" should not be used for metals

Samples that have been leached and analyzed should be coded as follows:

Leaching procedures are indicated by a value other than “NONE” entered in the LCHMETH field.   The appropriate EXMCODE will be that used or performed on the leachate itself.  If further processing of the leachate is performed prior to analysis, enter the appropriate EXMCODE i.e.: SW5030 for purge and trap methods, or SW3510 for semi-volatile analyses.  If no further processing of the leachate is performed prior to analysis, use the EXMCODE “NONE”.
