Air Quality Monitoring Network

The monitoring network provides data concerning Pinal County’s air quality so that we can assess compliance with the National Ambient Air Quality Standards (NAAQS) as required by the Federal Clean Air Act. The federal Environmental Protection Agency (EPA) sets air quality standards to protect our health. The standards define how much air pollution is safe in the outdoor air.

Pinal County Air Quality currently measures ozone and particulate matter levels by operating a network of monitoring and sampling equipment throughout Pinal County. The equipment at an air monitoring station can vary from a complex array of continuous air monitors that operate 24 hours a day year-round to a single sampler with a filter that captures particulates every 3—6 days. Data generated from this monitoring network is carefully reviewed, edited and analyzed prior to submittal into EPA’s national air quality database referred to as the Aerometric Information Retrieval System-Air Quality System (AIRS-AQS). The data submitted to this EPA database can be downloaded by visiting the Air Quality System Data Mart webpage. Summary data files for Pinal County continuous particulate matter samplers and ozone monitors are available at the bottom of this page.

The Air Quality Index (AQI) is a mechanism for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. Click here to view AQI information from the monitors that run everyday within Pinal County.
