Air Pollution Monitoring


To monitor the quality of outdoor air by testing for harmful pollutants.

What we do

  • Conduct air pollution analyses through a network of eight air-monitoring stations located throughout the state and maintained in cooperation with the Department of Environmental Management.
  • Measure multiple outdoor air pollutants including sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, volatile organic compounds, airborne toxic compounds, metals, and particulate matter.
  • Report ground level ozone and particulates measurements to the RI DEM for the publicly reported air quality index used to issue alerts when expected levels are unhealthy.
  • Electronically share air quality data with the EPA Air Now database to develop air quality trend models and air pollution control measures.


  • Approved by the USEPA to measure ambient concentrations of pollutants for which the EPA has established a National Ambient Air Quality Standard (NAAQS).
  • Conducts continuous air quality monitoring at urban, suburban and coastal sites in Rhode Island.
  • Reports RI Air Quality Data to
  • Supports investigations conducted by DEM Office of Air Resources
