The Texas Commission on Environmental Quality has expanded its network of air monitoring stations by introducing two new monitoring stations in Central Texas. One location is in Comal County and the other in Bexar County. Both monitors are now operational.

The stations take measurements of particulate matter in the air, commonly notated as PM2.5 and PM10. Particulate matter is a mix of small particles and liquid droplets and can be created by both natural and manmade causes, including incomplete combustion, smoke from fires, and dust or dirt from unpaved roads or construction activities.

Quarries and their associated aggregate operations are also common sources of particulate matter. TCEQ deployed these monitors in response to citizen concerns regarding local air quality in areas of heavy quarry activity near residential areas.

Both monitoring stations are positioned in residential areas about one mile downwind of existing quarry operations. The New Braunfels station in Comal County is on Oak Run Parkway, and the San Antonio station in Bexar County is near Bulverde Road, north of FM 1604.

Texans can access the monitoring data here and can stay aware of the state’s air quality index by visiting TCEQ’s Air Quality Forecast webpage. The forecast is also tweeted daily to the agency’s Twitter feed.
