Unlike the good, protective ozone layer in the upper stratosphere, ground-level ozone is a harmful air pollutant that affects all of us. It’s formed when emissions from everyday activities like:
- Solvent use
- Lawn mowing
- Industrial emissions
When combined, these pollutants “cook” in the heat from sunlight to form ozone.
Ozone continues to be a serious health issue and air pollution concern in Boulder County, and the nine-county Denver region. Currently five monitors along the Denver Metro Area/North Front Range indicate ozone levels that significantly exceed the new ozone standard, including the monitor in south Boulder.
