Round Rock Fire Station (RRTX) Air Monitoring Station, Round Rock, Texas

Round Rock Fire Station (RRTX) is an air monitoring station located at 203 Commerce Blvd in Round Rock, Williamson County, Texas, United States. The facility is operational and serves as part of the broader environmental monitoring network in the region, collecting data on ambient air quality to support public health and regulatory compliance. The station operates under the oversight of Eastern Research Group, a reporting agency that manages data collection and submission. While specific parameters measured are not detailed, typical air monitoring stations in Texas track criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, in accordance with US EPA National Ambient Air Quality Standards (NAAQS). The station's location in a suburban setting near Austin provides representative data for urban-influenced air quality. Round Rock Fire Station (RRTX) plays a role in the Texas Commission on Environmental Quality (TCEQ) air monitoring network, which supports compliance with the Clean Air Act. The data collected helps assess regional air quality trends, inform public health advisories, and guide emission reduction strategies. The station's ongoing operation ensures continuity in long-term air quality records for the growing Round Rock area.

The station is situated in Round Rock, a rapidly growing suburb of Austin, Texas, where urban expansion and traffic emissions influence local air quality. Monitoring criteria pollutants like ozone and particulate matter is critical due to the region's nonattainment status for ozone under the EPA's standards. The station's siting near a fire station provides a secure location but may reflect local microenvironments rather than regional background levels. Reporting continuity through Eastern Research Group supports the EPA's Air Quality System (AQS) database.
