Operational Unit
Cumulative Impact & Synergistic Chemical Exposure Modeling Team
Environmental Justice & Industrial Accountability
Unit Mandate
Mission & Operational Scope
Models the combined health effects of simultaneous exposure to multiple environmental stressors — air pollutants, water contaminants, noise, heat, and psychosocial stress — in frontline communities, producing cumulative risk assessments that single-chemical frameworks miss.
Doctrine
EPA Framework for Cumulative Risk Assessment · NAS Exposure Science in the 21st Century
Core Capabilities
Operational Capabilities
Multi-pathway cumulative exposure assessment (air, water, soil, food, dermal)
Chemical mixture toxicity assessment (dose addition, response addition, interaction)
Non-chemical stressor integration (noise, heat, psychosocial stress) in cumulative risk
Probabilistic risk assessment using Monte Carlo simulation
Sensitive population (children, elderly, immunocompromised) vulnerability modeling
Cumulative risk communication and community-accessible reporting
