Air Quality

The Arizona Department of Environmental Quality (ADEQ) has extended the High Pollution Advisory (HPA) through Saturday and Sunday, June 4 to 5, for Maricopa County.

Due to a stagnant weather pattern and abundant sunlight, ozone levels are expected to accumulate enough to exceed the federal health standard through Sunday.

Central and west portions of the Valley will likely see increasing ozone levels in the coming days as the high pressure situates itself more directly over Arizona.

The Arizona Department of Environmental Quality (ADEQ) has issued a same day Health Watch for today, June 1, and a High Pollution Advisory (HPA) for Thursday, June 2, for ozone in Maricopa County.

An Ozone Health Watch means that ozone levels are expected to near the federal health standard. Tomorrow, ozone levels around the Valley are expected to increase with highest ozone levels concentrating in north and northeast portions of the Valley.

The Arizona Department of Environmental Quality (ADEQ) has issued an ozone Health Watch for tomorrow, May 13, for areas in and bordering Maricopa County.

Stable weather conditions will remain over the region Friday; therefore, there will not be a High Pollution Advisory. However, ozone is expected to approach the federal health standard. By Saturday, a trough to the west will begin to move into the area causing ventilation to improve.

The Arizona Department of Environmental Quality (ADEQ) has issued a Ozone High Pollution Advisory for tomorrow, May 11, for areas in and bordering Maricopa County.

ADEQ issues health watches and pollution advisories when the highest concentration of ozone or particulate matter levels may exceed the federal health standard.

People are encouraged to make voluntary efforts to limit activities that cause air pollution. People with respiratory or other health problems that make them more sensitive to air pollution are advised to limit their outdoor activity.
