Decontamination and Consequence Management

The Decontamination and Consequence Management Division (DCMD) focuses on rapid and cost-effective remediation and restoration of buildings and broad outdoor areas.

DCMD's Mission

DCMD research identifies the optimal
technologies and procedures for protecting
decontamination crews, the general public,
and the environment. Scientists at EPA and
numerous cooperating government agencies
are working to develop new methods for
detecting and containing chemical, biological,
and radiological hazards; decontaminating indoor
and outdoor environments; and disposing of
contaminants following a terrorist event.

Detection

Detection research ensures that the sampling and analysis
methods, both for detecting contamination and for verifying

successful decontamination, will be available when needed. Research activities include:
• Developing portable detection systems for chemical agents in the air or on
surfaces

Adapting laser technologies for real-time detection of both chemical and
biological agents

Developing methods for rapid, accurate, and sensitive detection of bacteria
after decontamination, with rapid assessment of viability
Developing procedures to sample indoor surfaces for the presence of
pathogenic bacteria and toxic chemicals
° Evaluating commercial technologies that might be used to detect airborne or
surface-bound contaminants

Containment

Containment research focuses on developing and testing methods to prevent
the spread of contaminants; to protect people by providing tools, techniques,
technologies, and guidance to minimize the impact of a chemical or biological attack
on building occupants; and to evaluate the effectiveness and economics of chemical/
biological protection measures for new and
existing buildings. Research activities include:

Evaluating the impact of HVAC design
and operation on indoor dispersion of
contaminants

Developing procedures to prevent the
spread of a contaminant
Evaluating the effectiveness of
residential safe havens
Developing spill/release models
to identify contaminated areas for
evacuation and decontamination
Studying indoor movement of
contaminants to predict how much

time building occupants have to escape or move to a safe haven
Studying the effects of human activities on dispersion of agents
Evaluating the impact of indoor materials, such as upholstery
and wallboard, on exposure to agents

Developing and evaluating new air cleaners and filters to remove toxic
industrial chemicals

Preparing guidance, training programs, and materials to limit the spread of
airborne contaminants released in or near buildings

Decontamination

The goal of decontamination research is to facilitate the selection of effective, safe,
rapid, and cost-effective technologies and methods for decontaminating indoor or
outdoor areas. Decontamination of porous building surfaces, such as carpeting and
ceiling tiles, is a major focus. Research activities include:

Field-testing commercially available decontamination methods and systems

•	Developing new methods for the decontamination of high-value or special
materials, such as electronics

Evaluating the health effects of residual decontamination chemicals and
reactions to byproducts

Systematically testing available decontamination methods to optimize
performance on specific materials

•	Testing improved site preparation methods and portable fumigation systems

Disposal

The purpose of disposal research is to provide guidance for disposing of contaminated
materials and wastes generated during decontamination. Researchers focus on the
tools, techniques, and technologies needed for the safe removal, packaging, transport,
and final disposal of contaminated materials. Research activities include:

» Evaluating pollutants likely to be generated by disposal and recommending
methods for minimizing their effects on the environment
Investigating thermal destruction as a means to safely dispose of biological
agents, carpets, building construction materials, air filters, adsorbents and
other cleaning materials

Determining the conditions of time and temperature required to ensure
adequate destruction

Assessing conditions for safe landfilling of building decontamination wastes
Developing Web-based guidance for emergency responders,
disposal permitters, and facility owners, addressing
safety and regulatory issues associated with
transport and disposal of contaminated materials

Stakeholders

Primary stakeholders include the EPA regions
and program offices, commercial, local and
state laboratories, emergency responders,
and other federal agencies involved with
emergency response.
