Hot Summer Days Could Mean High Ozone
Last summer, a number of ozone monitors around the state saw ozone levels over the
70 parts per billion standard (8-hour average). Ozone at ground level is a harmful air pollutant because of its effects on people and the environment, and it is the main ingredient in smog. It is important to do what we can to help lower harmful levels of ozone. Simple activities, like waiting to refuel your car until later in the day and avoiding unnecessary car trips, can help.
