Chemical Stressors

Emerging Contaminants Program

Emerging contaminants (EC) are defined by the Department of Defense (DoD) as chemicals or materials that either lack published health standards, have an evolving regulatory or science status or pose a threat to human health or the environment with the potential to impact mission readiness. The program is managed under the Assistant Deputy Under Secretary of Defense for Environment, Safety and Occupational Health as delineated in DoD Instruction 4715.18, Emerging Contaminants (EC). As an active member of the Chemical and Material Risk Management Directorate's Materials of Evolving Regulatory Interest Team (MERIT), we participate in the coordinated effort of the military services to develop processes and approaches that enable:

  • Early identification of emerging contaminants with relevance to DoD
  • Assessing and minimizing occupational safety and health impacts for DoD personnel
  • Developing workable and innovative risk management options

We provide subject matter experts for specific EC impact assessments. This includes researching and evaluating information on Navy operations and processes where the chemical is used, analyzing exposure data to assess human health risks for the chemicals under scrutiny, and proposing less hazardous alternatives.
