The Maricopa County air monitoring division maintains several ambient air monitoring networks within the borders of Maricopa County.
The purpose of the ambient air monitoring network is to sample air pollution in a variety of settings, assess the health and welfare
effects, and assist in determining sources of air pollution. In general, six basic monitoring objectives and five measuring scales are used to determine
the network design. Additional items such as availability of power, accessibility to site, security, geographic location, and fiscal and personnel
resources are also used in determining feasibility of the network design.
Since it is physically and fiscally impossible to monitor the air in every location, representative samples must be obtained. These
samples are determined by using the monitoring objectives and the spatial measurement scales. The network must be dynamic enough to maintain a current
representative sample of the air quality. Air quality issues such as eight-hour ozone non-attainment boundaries and permits for new sources are diverse
and controversial subjects for the citizens of Maricopa County. With its robust air monitoring network and mobile monitoring tools, the department strives
to provide the most reliable and relevant air monitoring data to the public.

A fundamental purposes of this review is to provide the citizens of Maricopa County with relevant information, so that they may make
better decisions about their lives. This information is used in a variety of ways. Most importantly it is used to determine the attainment status for
parts of Maricopa County. Another purpose is to determine permit conditions of new industries. Mathematical models are created using the data to
determine the effectiveness of control programs on pollution levels. Also, other models are created to determine the possible locations of new sites
and help in pollution forecasts.
