Under many jurisdictions, facility owners are required to evaluate potential off-site air quality impacts as part of the approval process. Our clients need consultants with expertise running air dispersion models that use mathematical algorithms to characterize atmospheric processes that disperse a pollutant emitted by a source and predict ambient concentrations of air contaminants.

Gesoyntec applies models to demonstrate compliance with regulatory agency-established allowable ground-level concentrations. We have experience applying various air dispersion models ranging from those that predict ground-level concentrations from continuous emission sources to consequence analysis models used to assess impacts from unplanned catastrophic events.

Geosyntec's air dispersion modeling capability enables us to assist clients with regulatory and non-regulatory air modeling projects, including permit applications to address ambient air quality and air toxic requirements. Our team works closely with clients to assess plant layout and stack location configurations to avoid negative modeling results. Our practitioners also conduct modeling to evaluate potential off-site impacts associated with risk assessments and hazard analyses. Our modelers are experienced with AERMOD/ AERSURFACE/AERSCREEN/ SCREEN3, CALPUFF, ALOHA, SLAB and Computational Fluid Dynamics (CFD) models.

Our advanced collection and measurement methods allow us to generate robust data for air dispersion models that describe the complex behavior of pollutants in the air and how they interact with their environment. Armed with this data, our engineers and scientists can accurately assess how a source affects a particular area and consult with clients on the development of comprehensive environmental management strategies.
