Air Quality Flag Program

Air Quality Index

Riverbank is flying new flags – one is located at Jacob Myers Park and one at the western entrance sign. These flags are displayed to show residents and visitors what our daily Air Quality Index is and whether or not we are having a clean air day. Air Quality Index or AQI, is how pollutants in our air are measured. There are five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution or particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. For people suffering from respiratory disease or asthma, knowing the air quality can help them protect themselves from these pollutants. Staff will monitor the Valley Air website each day and will change the flags as needed. There are four colors, each with its own meaning: green means the air quality is good with 0-50 AQI; yellow is moderate 51-100 AQI; and orange flag means the air is unhealthy for sensitive groups 101-150 AQI; and red means unhealthy for all, 151-200 AQI.

If your daily trip does not take you past one of the flags, you can still find out the day’s reading by going to the Valley Air website at www.valleyair.org click on “Air Quality Information”, then “Daily Forecast” or call 1-800-766-4463.

Persons with asthma or other respiratory illnesses can find more information from the Stanislaus County Asthma Coalition at 209-558-4846 or visit their website at www.stanasthma.org.
