AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Updated Tuesday, October 17, 2017 Stanfield’s PM10 level yesterday was at the health standard (100 on the AQI scale), second day in a row with elevated particulates. Unfortunately today is starting off in similar fashion at Stanfield and so today may be the 3rd day in a row at Stanfield where the particulates approach and perhaps exceed the health standard (which is what happened on Sunday). On the good side of the news, the local winds early this morning at Hidden Valley are opposite what they usually are (northerly direction rather than the usual easterly) which is keeping the morning PM10 emissions away from the monitor. So today’s Hidden Valley PM10 levels most likely won’t exceed the health standard as forecasted. However, the next few mornings will have light winds and so localized PM10 emissions at Hidden Valley are expected to impact the monitor and so the forecasted exceedances for Wednesday and Thursday remain. High pressure will be in control of the region the next few days before a trough skirts by to the north on Friday. Unfortunately there is no rain in the forecast and so ground surface conditions will continue to be dry. Stay up to date with current air pollution levels by checking out the near real-time PM10, PM2.5 and ozone levels online at http://www.pinalcountyaz.gov/AirQuality/Pages/AirQualityReport.aspx. The PM2.5 levels will follow behind the PM10 levels and be in the range of upper good to upper moderate on the AQI scale. The ozone levels are expected to be in the upper good to low moderate range on the AQI scale today and good for the remainder of the work week. Forecaster: Forecaster: S. DiBiase
