CTEH® performs atmospheric dispersion modeling (ADM) for emergency, planning, and permitting situations. ADM is used to estimate temporally- and spatially-resolved atmospheric concentrations of a chemical by using release, meteorological, and topographical information. Release rate estimates are developed by CTEH® chemical engineers using state-of-the-science algorithms and estimation tools. Meteorological information is obtained through multiple methods, and topographical information is included where appropriate. This important estimation process helps the toxicology component of CTEH® to assign areas of risk to a particular event.
The CTEH® Chemical Modeling Team is designed to construct reliable dispersion models for chemical incidents to assist our clients in identifying the impact of un-intended chemical releases. CTEH® utilizes the latest SAFER Star chemical modeling technology and routinely implements the latest advancement in chemical modeling capabilities. The CTEH® Chemical Modeling Team provides air dispersion models for industry clients, incident command operations, and the legal environment to support the analysis of:
Real-time air monitoring information is incorporated to further refine the accuracy of the model. CTEH® utilizes sophisticated real-time air monitoring data collection capabilities, making data immediately accessible to the modeler. CTEH® can rapidly deploy 7 mobile weather stations for collecting on-site meteorological data. In addition, CTEH modelers have licensed access to an extensive network of weather stations throughout North America for remote modeling capabilities
The CTEH® Chemical Modeling Team is made up of 16 chemical modelers with technical emphasis in toxicology, industrial hygiene, and environmental science. The team is made up of:
CTEH® uses SAFER STAR™ (SAFER) to help manage an emergency and to provide early warning to those who may risk exposure to a potentially harmful substance. SAFER accurately models the effects of chemical accidents (toxic releases, fires and explosions). The program includes state-of-the-science algorithms for addressing atmospheric dispersion, thermal radiation and blast overpressure modeling. In addition, SAFER provides mapping and topographical databases for the region of interest. Once the release site is identified, SAFER rapidly assembles appropriate maps and topographical data.
