Ambient Air Monitoring

National Ambient Air Quality Standards (40 CFR part 50) for pollutants considered harmful to public health and the environment. The Clean Air Act identifies two types of national ambient air quality standards. Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings.

The air quality standards monitor:

  • Nitrogen dioxide
  • Ozone
  • Particle pollution
  • Sulfur dioxide

The airshed in Akwesasne is designed for the ambient air monitoring we are conducting to observe levels present in our community. We do monthly charts showing the data and calibrations or precision checks just to be sure that the data and the quality of the data is up to par and that the air quality in Akwesasne is at safe levels.

As part of the air monitoring station the program also has a meteorological station. The station monitors for temperature, wind speed, wind direction, relative humidity and barometric pressure. It is available online at:
