Air Quality Index (AQI) Basics

WHAT IS THE U.S. AIR QUALITY INDEX (AQI)?

The U.S. AQI is EPA's index for reporting air quality.

HOW DOES THE AQI WORK?

The U.S. Air Quality Index (AQI) is EPA's tool for communicating outdoor air quality and health. The AQI includes six color-coded categories, each corresponding to a range of index values. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

For each pollutant, an AQI value of 100 generally corresponds to an ambient air concentration that equals the short-term national ambient air quality standard for protection of public health. AQI values at or below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is unhealthy: first for certain sensitive groups of people, then for everyone as AQI values get higher.

The AQI is divided into six categories. Each category corresponds to a different level of health concern. Each category also has a specific color. The color makes it easy for people to quickly determine whether air quality is reaching unhealthy levels in their communities.

Government air data

Air quality data for the Bay Area is currently reported by government regulatory air monitors which can be found at https://www.baaqmd.gov/about-air-quality/current-air-quality

Data reported by IVAN Air Monitoring and by government monitors should both be used to better understand air quality levels near you. There are differences in how these data are collected, such as the locations monitored, the equipment used, and pollutants measured. Therefore, differences in reported air data are expected. When considering how to best protect your health, we recommended you consider multiple sources of air quality data and follow the most health protective recommendations.

Visit the Air Monitoring FAQs for more information about how our data compares with government data.

Report an air problem

If you are experiencing an emergency, call 9-1-1.

Step 1. Report to Bay Area Air Quality Management District (BAAQMD).

Call 1-800-334-ODOR (6367) as son as you notice a problem with air quality. Their website also offers an opportunity to submit an online complaint and lists additional complaints that are outside of their jurisdiction they may not be able to respond to.

Step 2. Report on IVAN.

After contacting BAAQMD, we recommend that you also submit a record of the problem here on BVHP- IVAN, including a note that BAAQMD has been contacted. This ensures that the Environmental Justice Task Force is aware of the complaint and that the complaint is documented on the BVHP-IVAN website.
