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.
Measurements & Objectives
In general, six basic monitoring objectives and five measuring scales are used to determine the network design. Additional items are also used in determining feasibility of the network design, such as:
Accessibility to site
Availability of power
Fiscal and personnel resources
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.
Reliable & Relevant Data
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.
