South Dakota earned generally good grades for air quality in the American Lung Association State of the Air Report issued today.  South Dakota operates air quality monitors in 10 counties, which measures two distinct types of air pollution: ground-level ozone and particulate pollution. While the state earned “A” or “B” grades for ozone pollution, two counties, Custer and Jackson,  slipped to a “C” grade for particle pollution from an “A” grade in last year’s report.  Union County also earned a “C” grade for particle pollution, unchanged from last year.  The entire report can be found at

The State of the Air Report covers a three year period from 2015 to 2017, analyzing data collected at the state’s air quality monitors and later certified by the U.S. Environmental Protection Agency.  Grades are determined by the number of air quality alerts for ozone or particle pollution that occurred during those three years.  

“The air quality statewide is generally pretty good, but the slipping grades in Custer and Jackson counties are cause for concern,” said Robert Moffitt, a spokesperson for the American Lung Association in South Dakota. “These grades can change due to factors like wildfire smoke drifting in from other states, but they also can indicate a growing health risk to the residents of these counties.”
