Contaminant Fate, Transport & Exposure
EPA develops procedures and methods to contain and mitigate contamination and to clean up the environment following public health and environmental incidents and disasters. Large scale contamination incidents could require the decontamination of multiple buildings and the outdoor environment, including water and wastewater systems. Knowledge of the fate (persistence and life cycle) and transport (movement) for various types of contaminants is key to understanding exposure mechanisms and informing sampling, cleanup, and restoration decisions.
EPA researchers are studying the potential for exposure from contaminants, including the impact of short-term exposures. For example, it's important to understand whether a contaminant released into the environment will continue to pose an exposure threat to people, animals, and plants over time. Information and models on exposure assessments can inform public health and cleanup decisions ranging from sampling, decontamination, waste management, and operational countermeasures.
