CASTNET Site Locations

CASTNET sites provide air quality information to rural and tribal communities that often lack other sources of ambient data. The map below provides geographic information and links to active and inactive CASTNET sites. Sites located within or near disadvantaged communities were identified using the CEQ’s Climate and Economic Justice Screening Tool (CEJST). More information about the CEJST methodology can be found here. Links are provided for the individual site pages in the pop-ups. Site pages contain a description of site characteristics, a graphical summary of air quality and deposition, and a list of site changes.
