We will use exposure models and atmospheric chemistry and transport models that account for the presence of canyons and other topographical variations to accurately characterize potential exposure to the blowout. We will use “distance decay models,” which will further identify areas of highest exposure and can assess whether health effects are more severe in those areas.

We will also place air pollution monitors and collect air samples in areas affected by the canyon winds because air flow through the nearby canyons could influence where chemicals emitted from the facility are currently dispersed and where they may have been dispersed during the blowout.
