The AQI is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health. Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in Indian Country.
Lower Sioux Indian Community has above average Air Quality with only a few days out of the year where for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. These days are when we have strong northeast winds which bring particulates down from the metro area or foggy dense days. People are not recommended to do any burning or heavy physical work on foggy dense days.Read More Environmental Resources
