Purple Air: Realtime Air Quality Conditions
The map below is generated by PurpleAir. This grassroots organization relies on volunteers to allow air sensors to be placed on their businesses or homes. PurpleAir uses the same scale that the Environmental Protection Agency uses – the Air Quality Index scale – to compare and measure pollutants in the air.
The scale uses green for good, yellow for moderate, orange for unhealthy for sensitive groups, red for unhealthy, purple for very unhealthy and maroon for hazardous. The Air Quality Index above is also useful, but only monitors several County-wide sensors. Click here to learn more about AQI.
Understanding Alert Levels
Agricultural Burn Permits allow burning year-round in Mesa County and during designated burn seasons within the City of Grand Junction
No Burn Advisory
If conditions warrant, a No Burn Advisory may be issued to protect the health of residents. When one is issued, restrictions are put in place on open burning or woodstove burning. Residents should note that woodstove burning restrictions do not apply to those who use a woodstove as a primary heat source.

Understanding Air Quality
What impacts our Air Quality
We use a measurement system called AQI (air quality index) developed by the Environmental Protection Agency (EPA) to assign a numerical value to the air quality. This system takes four major air pollutants into account, ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The higher the AQI, the greater the level of air pollution.
