The Connecticut Department of Energy and Environmental Protection (DEEP), Bureau of Air Management, Ambient Air Monitoring Group monitors air quality to protect public health and the environment.  The monitoring of air quality data is crucial to determine compliance with the Federal EPA primary and secondary air quality standards and to evaluate how well pollution control and abatement strategies are working to clean the air.

The criteria pollutants measured in the ambient air monitoring network are: ozone (O3), particulate matter (PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO) and lead (Pb). The DEEP has also monitored for toxic pollutants and metals including volatile organic compounds, aldehydes, polycyclic aromatic hydrocarbons, mercury and dioxin.
