If you smell or are otherwise experiencing foul air, please report it to the health department. They have cited low numbers of reports to say that there isn't a problem. You can report directly to the health department here: https://alleghenycounty.mycusthelp.com/WEBAPP/_rs/(S(35aswslwbnu4f1oylgxapty0))/SupportHome.aspx?sSessionID=&lp=10

Report it on Smell PGH too but the health department has a really bad habit of ignoring those reports.
