Air Quality program

The Air Pollution Program monitors the ambient air in San Antonio. The program Monitors for particulate matter 2.5 microns in size (PM2.5) and particulate matter 10 microns in size (PM10). These small particles could cause respiratory problems for small children, the elderly and the general public. The program also operates and maintains an ozone monitor located at Calaveras Lake for the Texas Commission on Environmental Quality (TCEQ).
