Questions concerning Selected Analytical Methods for Environmental Remediation and Recovery (SAM), this website, or the methods identified within SAM 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 in SAM. As previously indicated, any deviations from the recommended method(s) should be reported immediately to ensure data comparability is maintained when responding to homeland security events. In cases where laboratories are specifically tasked by EPA to use these methods following an event, method deviations or modifications must be approved by the Analytical Service Requestor (as defined by ERLN) prior to use. In addition, general questions and comments can also be submitted via Contact Us. See: Contact Us
