SAM Technical Contacts

Questions concerning this document, or the methods identified in this document, should be addressed to the appropriate point(s) of contact identified below. EPA recommends that these contacts be consulted regarding any method deviations or modifications, sample problems or interferences, QC requirements, the use of potential alternative methods, or the need to address analytes or sample types other than those listed. Any deviations from the recommended method(s) should be reported immediately to ensure data comparability is maintained when responding to intentional or unintentional contamination incidents. In cases where laboratories are tasked by EPA to use these methods following an incident, method deviations or modifications must be approved by the Analytical Service Requestor (as defined by ERLN) prior to use.
