Cesium’s Movement in the Natural Environment
EPA has studied Cesium’s interactions with the natural environment at the bench, pilot and field-scale.
-
Cesium’s Interaction in the Built Environment
EPA experimentally assessed the migration of cesium into urban materials, including asphalt, brick, concrete, limestone, and granite.
-
Chemical Fate & Transport
EPA conducts research to help responders and decision makers understand the fate and transport of chemical warfare agents (CWAs) so that they can minimize human health effects and environmental impacts following the release of a CWA.
-
Contaminant Fate, Transport & Exposure
Large scale contamination incidents can affect a wide variety of surfaces, environments, and infrastructure. Knowledge of the persistence, life cycle, and movement of of these contaminants can help inform sampling, cleanup, and remediation decisions.
