Updated: 7:53 PM CDT April 28, 2021 MEMPHIS, Tennessee — A new report says that while Memphis’ air quality has made ‘significant progress,’ it still received a failing grade. The ‘F’ grade for Memphis was in the American Lung Association "State of the Air 2021" report, which ranks cities --and grades counties-- based on ozone and particle pollution during 2017, 2018 and 2019. Data from the U.S. Environmental Protection Agency (EPA) was used to compile the annual report card for all cities and counties where air quality data is collected on ozone and particle pollution. According to the data, more than 123 million people lived in a county earning a failing grade for ozone pollution, including over 28 million children and over 18 million people age 65 or older.
