The Regional Air Pollution Control Agency is committed to operating a quality-assured monitoring network that generates accurate measurements of ambient air quality in its jurisdiction. These monitoring data are used to measure progress toward attainment of EPA’s National Ambient Air Quality Standards (NAAQS), assess source contributions to air pollution, and assist in the protection of public health.
RAPCA operates and maintains 30 ambient air quality monitors at 11 sites ,distributed over five counties in RAPCA’s six-county jurisdiction.
Monitoring sites are selected based on a number of factors including computer modeling of atmospheric chemistry and air dispersion, access to power, security, and public interest.

Monitor Descriptions
For more information about RAPCA's air quality monitoring program, please see our Annual Ambient Air Monitoring Network Review.
* The Claridge monitoring station is included on this list because the data from 2005-2007 was used in the designation of the 2008 8-hr ozone National Ambient Air Quality Standard. The station was replaced by Site 49 at the beginning of the 2008 ozone season. |
