EPA Continues to Update its Environmental Sampling & Analytical Methods (ESAM) Program

Published November 19, 2019

EPA’s Homeland Security Research Program (HSRP) aims to increase the United States’ capabilities to prepare for and respond to environmental disasters involving chemical, biological, radiological, and nuclear substances (CBRN). As part of this effort, EPA researchers develop scientific data, methods, and tools that can be used by various stakeholders, including laboratories and on-scene coordinators, to increase the effectiveness of response.

One of HSRP’s most important efforts is the Environmental Sampling & Analytical Methods (ESAM) Program. Launched in 2018, the ESAM program and associated website is a one-stop resource for field-and-laboratory-ready documents and web-based tools supporting characterization and post-decontamination sampling of sites following an intentional or accidental homeland security-related contamination incident.

The ESAM webpage has five distinct sections of resources that support the remediation of a contaminated site.

EPA will continue to development and re-evaluate analytical methods and protocols to support laboratories faced with incident response.
