TM17-01 Modification to the reporting of elemental results for whole-water recoverable (WWR) sample analyses with old and new laboratory and method codes

This technical memorandum describes the implementation of a correction to account for dilution during digestion of whole-water recoverable samples analyzed at the National Water Quality Laboratory, using inductively coupled plasma-optical emission spectrometry and inductively coupled plasma-mass spectrometry. It also describes the procedure used to apply the dilution factor to elemental results.
