Report pollution incidents through our app right when you experience them


Where do the data come from?

Most of the data on our site come from Unlike, however, our site displays archived data from as far back as May 2015. The rest come from BAAQMD monitors or inexpensive monitors set up by community members.

Who decides what level of a given chemical constitutes a health hazard?

Health limits vary widely between governmental agencies. Our site uses figures from the US National Ambient Air Quality Standards (NAAQS), the Agency for Toxic Substances and Diseases Registry (ATSDR), and the California Office of Environmental Health Hazard Assessment (OEHHA). In the interest of public health, we chose the lowest figures that were deemed hazardous for each chemical.

An air pollution event occurred in my community, but the monitors didn’t pick up anything. What happened?

Events that occur outside the range of the sensors may not appear on the site. What the monitors pick up depends highly on the location of the pollution source, and the wind speed and direction at the time of the event.

Why are schools and daycares included on the map?

Air pollution carries higher risks for vulnerable populations—which includes children and the elderly. Because our aim is to contextualize air pollution data in how it impacts real people, we wanted residents to be able to see whether an air pollution event might impact their children.


Report a Pollution Incident
(i.e. flaring, odor, residue, health symptoms)

When you report to Air Watch Bay Area, you contribute to a publicly visible "paper trail" of incidents.
Having this paper trail enables community members to hold Bay Area Air Quality Management District accountable.

Resources for Action

Connect with Bay Area community organizations, campaigns, and resources

to advocate for cleaner air, particularly in frontline communities.

Connect with elected officials and regulators

responsible for Bay Area air quality and protecting public health.

Learn about Bay Area oil refinery politics and policies

—especially, the push to refine heavier crude oils in West Contra Costa and Solano counties. Refining heavier, more carbon-intensive oil would lead to higher levels of pollution and greater impacts on public health and environmental justice.

Learn about California oil refinery politics and policies

—especially, the ongoing influence of Big Oil and its emphasis on cap-and-trade pollution markets, to the detriment of frontline communities. Even as California aspires to climate leadership, these politics often undermine policies to address climate change, public health, and environmental justice.

Explore environmental health and health equity research

pertaining to air pollution, public health, greenhouse gases (GHGs), and environmental justice.

Investigate community-based science, participatory design, and data politics

including collaborations among scientists, engineers, programmers, and community activists like Air Watch Bay Area.

Climate Justice Educational Resources

Grow the community

of people engaged with Bay Area air quality, environmental justice, participatory design, and health equity advocacy.
