The Environmental Molecular Diagnostics (EMD) web-based guidance describes a group of advanced and emerging techniques used to analyze biological and chemical characteristics of environmental samples. EMDs have applications in each phase of environmental site management and provide additional lines of evidence for making better decisions. The guidance document provides descriptions of each of the major EMDs, along with case studies of their uses and recommendations regarding the appropriate uses of these techniques. The EMD web-based guidance document will help you to understand how EMDs could benefit your site management decisions.
