Laredo Bridge Air Monitoring Station, Laredo, Texas | United States Environmental Monitoring

Laredo Bridge is an air monitoring station located at 700 Zaragosa St in Laredo, Texas, within Webb County. Operated under the BORDER GRANT network, this station is part of the Texas Commission on Environmental Quality's (TCEQ) ambient air monitoring program. As a fixed-site monitor, it contributes to the state's air quality surveillance along the U.S.-Mexico border. The station operates under the regulatory framework of the U.S. EPA's Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. While specific parameters measured at this site are not detailed, typical border stations monitor a subset of these pollutants to assess cross-border air quality impacts. The station's last reported sample date is May 31, 2025, indicating ongoing data collection. Laredo Bridge's location near an international port of entry makes it significant for understanding transboundary air pollution and its effects on local communities. Data from this station supports TCEQ's efforts to protect public health and the environment in the Laredo area, a region with heavy vehicular traffic and industrial activity. The station's role in the BORDER GRANT network underscores its importance in binational environmental monitoring.

Laredo Bridge monitors ambient air quality in a region influenced by heavy traffic from the Laredo-Nuevo Laredo border crossing and nearby industrial facilities. The station's siting near a bridge aims to capture emissions from vehicles and trade-related activities. Typical parameters include criteria pollutants like PM2.5 and ozone, which are relevant for assessing health risks in a densely populated border city. The station's data contributes to understanding local air quality trends and supports regulatory compliance with EPA standards.
