HPA Alert

 
Maricopa County and the Running Out of Air program would like to invite you to sign up for our Health Watch and High Pollution Advisory text alerts.
 
The State of Arizona will call a Health Watch when the highest concentration of dust or ozone may approach the federal health standard. A High Pollution Advisory is called when dust or ozone levels may exceed the federal health standard. Once you sign up for the text alert service, you will receive notice the day before a possible Health Watch or High Pollution Advisory. You will then be able to take steps to help us clean the air.
