Air Quality

Air quality plays an important role in our daily lives as it affects our health, comfort and productivity. The quality of air to which we are exposed can be evaluated in order to identify various pollution sources, as well as to control the level of exposure to these pollutant and to adopt the appropriate corrective measures. As part of WSP’s continued commitment to provide quality services by leading professionals, we are pleased to offer an expanded service line to assist with air quality by providing solutions for ambient, atmospheric and indoor air challenges.

State-of-the-art equipment, strategic modelling and risk assessment techniques enable our teams to evaluate problems accurately and to engineer workable solutions to complex and potentially costly environmental issues.

Our approach to air quality modelling is characterized by our depth of expertise, and a firm commitment to quality assurance and innovation. Our modelling experts have a range of resources available, from initial screening assessments to complex source and terrain modelling. These techniques are used on a client-specific and project-specific basis to provide our clients with the most appropriate solutions for their needs. We make use of a range of dispersion modelling platforms including AERMOD and CALPUFF, each of which are implemented according to project and client requirements.

Our air quality and risk assessment specialists work closely together to ensure integration of air quality monitoring and modelling with assessment of human health or environmental risks and cost-effective management of air quality issues.
