Mobile Air Monitoring Project – Website now Live!

February 11, 2026

A first-of-its-kind, mobile air monitoring project is happening in New Jersey aiming to learn more about air toxics in Overburdened Communities. A mobile van equipped with air research-grade monitoring equipment will measure air toxics, criteria pollutants, and greenhouse gases in real-time, driving slowly on a pre-determined route, to match real-time pollution data with real-time location data. To learn more about the project and any upcoming events, visit our new website!
