Criteria Pollutant Monitoring

Air Monitoring Criteria Pollutant Monitoring

The U.S. Environmental Protection Agency sets national ambient air quality standards (NAAQS) for seven criteria pollutants: ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), respirable fine particulates (PM2.5), coarse particulates (PM10) and lead (Pb).

Air Resource Specialists provides turnkey solutions for criteria pollutant monitoring, from consultation on station/network design, through fabrication and installation, to training, operations and data reporting. Based on client requirements, ARS has fabricated numerous permanent as well as mobile stations which operate in urban, rural and remote locations.

Our clients typically require EPA Federal Reference Method (FRM) or Federal Equivalence Method (FEM) monitoring instruments, but sometimes low-cost sensors or personal monitors are a better choice for their application. Monitoring goals range from comparison to NAAQS to Prevention of Significant Deterioration (PSD) to pollutant screening or environmental research.

ARS also develops and supports client web sites for the presentation of collected data. These can be publicly available or private. An example of a public web site we built is for the National Park Service ozone network.

ARS has extensive experience developing and maintaining monitoring networks to meet PSD, SLAMS and EPA quality assurance requirements for criteria pollutants.
