 The Maricopa County area meets health-based standards for all air pollutants
except Particulates (dust). Particulate (dust) pollution continues to be a
major problem, and the City of Mesa has taken a leadership position to reduce
particulate pollution. Our program includes efforts to identify and
enforce control measures at sites that contribute to this problem. Read more information on the
"Particulate Matter" (Dust) and ways that you can help.
