Air Quality Monitoring Stations of the Texas Commission on Environmental Quality and its Partners in the Texas-Mexico Border Region
The TCEQ collects data from 18 air-quality monitoring stations in the Texas border region, and all information is available to the public.
The following three tables offer information on the 22 monitoring stations at which the TCEQ collects data on ambient concentrations of air pollution in the Texas’ border region with Mexico.
The tables are divided geographically. The first table covers the El Paso area and Big Bend National Park. The second table includes the area from Amistad Dam to Falcon Dam. The third table includes the Lower Rio Grande Valley (between Falcon Dam and the Gulf of Mexico). The column on the right in each table provides a link to more detailed information, including additional links to both historical and today's data.
