Hyperlocal, community-owned air monitoring
The WOAQ monitoring network is a community-owned network of air quality sensors that help us advocate for stronger environmental policies and enforcement by telling a detailed story of our neighborhood’s exposure to air pollution.
Hyperlocal measurement tells a more complete story
For years, there was only a single sensor in West Oakland, placed high above the neighborhood where it could not pick up detailed changes in the air that residents were breathing at ground level. Since 2008, WOEIP has partnered with researchers and technology companies to develop groundbreaking, hyperlocal maps that tell a more complete story about the sources of air pollution in our neighborhood, and who is most impacted from block to block.
Using this data, WOEIP helps visualize for policy makers what the community already knows: air pollution and its risks are unevenly distributed, and historically marginalized communities bear the burden.
Advanced technology in the community’s hands
We’ve installed air quality sensors throughout West Oakland, focusing on West Oakland’s air quality impact zones. These are neighborhoods that experience higher levels of air pollution exposure and health risks, according to the West Oakland Community Action Plan.
What do the sensors measure?
The WOAQ monitoring network uses three different types of air sensors that allow us to capture a variety of dangerous pollutants. These include black carbon (BC), particulate matter (PM2.5), and more. These pollutants cause serious health issues, including asthma and other respiratory illnesses, heart disease, and increased cancer and mortality risks.
Black carbon, metals and dust
This dual-sensor combination measures black carbon (BC), which primarily comes from diesel exhaust, as well as toxic metals and dust. We currently have 7 combo sensors installed in the WOAQ monitoring network, and plan to install several more.
Fine particulate matter (PM2.5)
For participants with location constraints, we use Purple Air sensors to measure fine particulate matter (PM2.5). PM2.5 comes from dust, smoke, vehicle exhaust, and other sources. We currently have 14 Purple Air sensors installed in the WOAQ monitoring network, and plan to install another half dozen or so.
Residents will be able to view air quality data from the WOAQ monitoring network later this year.
Host a WOAQ sensor
Help us better understand air pollution levels in your neighborhood! Being a site host is a great opportunity to support your community. Selected site hosts are financially compensated, trained, and provided with a support team to help manage the air sensor. If you own fenced property with an exterior power source, complete an interest form and we’ll add you to the waiting list.
Because of site-specific requirements and other program details, eligibility isn’t guaranteed.
