Aeration: The process of adding air to water. Air can be added to water by either passing air through water or passing water through air.
Aerobic: Requires air or oxygen to function.
Aeration: The process of adding air to water. Air can be added to water by either passing air through water or passing water through air.
Air Binding: A situation where air enters the filter media. Air is harmful to both the filtration and backwash processes. Air can prevent the passage of water during the filtration process and can cause the loss of filter media during the backwash process.
Air Gap: An open vertical drop, or vertical empty space, that separates a drinking (potable) water supply to be protected from another water system in a water treatment plant or other location. This open gap prevents the contamination of drinking water by backsiphonage or backflow because there is no way raw water or any other water can reach the drinking water.
Air Quality Division (AQD) of ADEQ: Protects and enhances public health and the environment of Arizona by controlling present and future sources of air pollution. Core responsibilities include collecting and analyzing quality assured and precise ambient air monitoring data; preparing pollution forecasts to help people limit their exposure to air pollution and air pollution sources; conducting and collaborating on research and analyses to evaluate pollution sources and their impacts on public health and welfare; investigating complaints and violations of, and achieving compliance with, Arizona's air pollution laws; issuing permits to industries and other facilities, and for open burning activities that protect public health and welfare; operating and maintaining accurate, convenient, and affordable vehicle emissions inspections programs; and developing air quality plans and rules through partnerships, collaboration and public involvement.
Air Quality Index (AQI): An index for reporting daily air quality. It determines how clean or polluted air is and what associated health effects might be of concern. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each pollutant, EPA has established national air quality standards to protect public health. Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
Air Quality Standards: The level of pollutants prescribed by regulations that are not to be exceeded during a given time in a defined area.
Air Sparging: An in-situ treatment technology that uses injected air to help remove harmful vapors from polluted soil and groundwater below the water table by injecting air directly into the saturated subsurface to encourage the solvents and gasoline to evaporate faster, which makes them easier to remove with a vacuum.
Air Stripping: A treatment system that removes or “strips” VOCs from contaminated groundwater or surface water as air is forced through the water, causing the compounds to evaporate. Often the compounds are then captured using air filters.
Airshed: A geographical area where local topography and meteorology limit the dispersion of pollutants away from the area.
Alluvial: Relating to mud and/or sand deposited by flowing water. Alluvial deposits may occur after a heavy rain storm.
Ambient Air: Outside air in the environment.
