Selected Analytical Methods for Environmental Remediation and Recovery (SAM) is updated periodically to incorporate revisions to the list of target analytes and environmental sample types, and to provide the most recent analytical methods and procedures. The table below provides information regarding the additional changes that were incorporated into each revision of SAM, since publication of SAM Revision 1.0 in September 2004.
