Overview

Ambient air quality surveys are primarily conducted at the request of national and local governments, as well as private companies, to assess ambient air conditions and evaluate the environmental impact of business activities.

We conduct a wide variety of ambient air quality surveys.
Examples include:
● Monitoring ambient air quality for national and local governments
● Assessments for factories, industrial facilities, road construction, and various construction projects
