In Atlanta, Georgia, the AQEarth team includes Community Health Aligning Revitalization Resilience & Sustainability (CHARRS) and West Atlanta Watershed Alliance (WAWA) in a project consisting of both air monitoring and community education. The collective aim is to bring community members together around air quality issues in West Atlanta neighborhoods. 2B Tech’s AQSync was installed to make high-quality measurements of pollutants that are accessible to residents online. Residents of all ages are exploring local air quality in neighborhoods using handheld personal air monitors (PAMs).
