Why the air was unsafe to breathe and reeked of “hospital waste” in a Pennsylvania community this Christmas
Residents of the Mon Valley, a cluster of townships along the Monongahela River 20 miles south of Pittsburgh, Pennsylvania, endured some of the stinkiest and most polluted air in the nation this Christmas.
Starting on December 21, the region’s air exceeded federal safety standards for daily levels of particulate matter—microscopic particles that penetrate the lungs and can trigger heart attacks and respiratory disease—for six consecutive days. One of the region’s air monitors recorded the worst air quality in the entire U.S. and registered in the “Code Red” range for several hours on multiple days.
Residents complained that the air smelled like “rotten eggs,” “sewer backup,” “burning plastic,” and “hospital waste,” and reported symptoms like wheezing, coughing and choking, nausea, stinging eyes and headaches through the SmellPGH app, which uses crowdsourcing to map smells and symptoms associated with air pollution.
The monitor that registered the Code Red sits near U.S. Steel’s Clairton Coke Works plant, which converts coal into “coke” used in steelmaking by cooking it at extremely high temperatures. The plant—one of the region’s primary sources of air pollution—is notorious for breaking clean air laws and sickening residents. But this time the facility was operating in full compliance with its permit, according to the Allegheny County Health Department, which oversees air quality in the greater Pittsburgh region.
