New air monitoring technologies, GIS systems and other technical tools make it possible for you to get real-time information about the air you are breathing. Interactive online tools let you monitor your air, post updates and immediately inform the Allegheny Health Department and/or the Pennsylvania Department of Environmental Protection when air pollution is bad – as well as alert your community through social media.
