Maryland's air quality has improved dramatically in recent years. These improvements have direct implications for public health, our quality of life and the economy. However, there is still much work to be done. The Maryland Department of the Environment encourages everyone to learn how air quality affects your health, follow our air quality forecasts and take steps to help keep Maryland's air clean.
