Tech Bulletin – Multiple Lines of Evidence

Summary:

This technical bulletin describes how integrating chemical, geochemical, and microbial data provides a robust multiple lines of evidence (MLOE) framework for evaluating bioremediation, monitored natural attenuation (MNA), and enhanced treatment performance. It highlights the use of molecular biological tools, isotope techniques, sequencing, and in situ microcosms to reduce uncertainty, improve remedy selection, and support defensible site management decisions.
