Air Quality Division is responsible for protecting Oregon's air quality. DEQ monitors air quality to ensure that the whole state meets and maintains national air quality health standards.
Healthy air is a key indicator of Oregon's quality of life.
Because of DEQ's successful air pollution prevention programs, and public support of them, one-hundred percent of Oregonians currently live where the air meets national health standards. That's a dramatic change from 1980 when only 30 percent of Oregonians lived in clean air areas. However, population and economic growth present constant challenges to maintaining healthy air in the state. DEQ Online is the official web site for the Oregon Department of Environmental Quality.
