Pinal County between Phoenix and Tucson has been one of the fastest growing counties in the United States. The county faces extreme summer heat and violent monsoon flash flooding. Haboobs — massive dust storms — regularly reduce visibility to near zero creating serious driving hazards. Florence hosts the Arizona State Prison Complex. The county hosts military training airspace and is in the 50-mile zone of Palo Verde Nuclear Plant. ADEQ Superfund sites dot the former copper mining landscape.
