What you can do if you smell a sulfur or rotten egg odor

1. Report it directly to the new Allegheny Health Department website
(click Request Service/File Complaint > Health Department > Air Quality)

2. Use the SmellPGH app (smellpgh.org) to report and track the odor

-You can also call the health department ACHD and report the odor

-You can view the PM2.5 air pollution in real time on the Purple air website. Link here. The Purple air network is comprised of small personally owned sensor units placed around the city that track Particulate Matter.

Note: Make sure to report it to the Health department & SmellPGH. The SmellPGH app is independent of the Health Department. So, it is important to submit complaints to both.
