Colorado’s Unrelenting Ozone Pollution Could Mean Long-Term Problems For Your Health

After repeated inquiries about the pollutant this summer, Scott Landes, Colorado’s air quality forecaster, started compiling data from previous years. He said the relevant data starts in 2015 when the EPA lowered the national ozone standard from 75 parts per billion to 70 parts per billion. Consistent measurements above the standard trigger an Ozone Action Alert from the state.
