What We Do

The Homeland Security and Materials Management Division (HSMMD) conducts an applied, customer-driven, national-scale research program to improve the nation’s preparedness for and response to environmental emergencies and materials management challenges.  HSMMD’s mission includes:

  • Understanding fate and transport of contaminants 
  • Developing innovative characterization tools and strategies
  • Developing analytical methods 
  • Developing wide-area cleanup technologies
  • Developing water treatment and related sensors
  • Developing water infrastructure decontamination methods
  • Management of oil spills, wastes, and other materials

HSMMD studies help in the development of systems-based decision support tools.  This research also supports the regulatory and non-regulatory scientific needs of EPA; water utilities; and state, local, territorial, and tribal agencies.
