ADEQ meteorologists issue air quality forecasts for pollutants such as ozone and particulate matter based on data collected at state-monitoring sites. These forecasts help inform the public when unhealthy pollution levels are anticipated | View Forecasts >
Nonattainment areas are classified by the Environmental Protection Agency (EPA) to have air quality monitoring data for criteria pollutants above the National Ambient Air Quality Standards (NAAQS) outlined in the Clean Air Act. These areas are designated conservatively and are not necessarily exceeding | Learn More >

Leaking USTs in Arizona
The following map shows where confirmed leaking UST sites requiring cleanup are located in Arizona. Please note the name of the current facility is listed on the map; due to business and property sales over time, the current facility may not be the responsible party at the time the leak occurred. A Public Records request may be submitted for information on the actual responsible party of the leaking UST | View Map >
Site/Facility of Interest (New Section Coming Soon)
Facility Information
The Copper World Project is located approximately 28 miles southeast of Tucson, Arizona in Pima County and about 12 miles southeast of Sahuarita, Arizona. The Copper World Project will be developed as an open-pit mining operation. Both sulfide and oxide ore will be mined and beneficiated. The project will include a milling and flotation circuit for the processing of sulfide ore, along with conventional tailings disposal. A heap leach facility (HLF) is planned that includes a lined heap leach pad (HLP) and associated lined ponds for the leaching of copper from oxide ore. The project also includes a solvent extraction and electrowinning (SX-EW) plant for processing of copper-rich solutions from the heap leach circuit and from a separate copper concentrate leach circuit. Sulfuric acid will be produced by an onsite sulfuric acid plant.
