Ozone Levels Were Unexpectedly High Yesterday
There was no air quality alert in effect yesterday, but air quality monitors show that ozone levels were at unhealthy levels in at least two areas.
The Cannons Lane monitor recorded levels at 83 parts per billion, which translates to an Air Quality Index of 119. At Watson Lane Elementary, levels were at 90 parts per billion, which is an AQI of 137. Levels between 101 and 150 are considered unhealthy for sensitive groups.
This was the 17th day with an ozone exceedance so far this year.
