Air Monitoring Stations
Keeping an eye on the environment is important to us. In order to ensure better air quality, we own and operate two comprehensive, continuous air-monitoring stations. These stations continually monitor ozone.
We record the presence of this constituent, as well as data on wind speed, wind direction and temperature to gauge how all these elements impact the quality of the air we breathe.
