PCI MET1 Air Monitoring Station, Escambia County, Alabama | US EPA AQS Network

PCI MET1 is an air monitoring station located on Jack Springs Rd in Escambia County, Alabama, United States. Operated by the Poarch Band of Creek Indians, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station is currently operational and reported a last sample date of December 31, 2024. As an air monitoring station, PCI MET1 likely measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, as well as meteorological parameters like wind speed and direction. The station's siting follows EPA guidelines to ensure representativeness of local air quality, particularly in a rural area of Alabama where industrial and agricultural sources may influence emissions. The environmental significance of PCI MET1 lies in its role in providing continuous air quality data for the region, supporting public health assessments and regulatory compliance. Data from this station contributes to the EPA's national air quality database, helping to track trends and inform policy decisions. The station's operation by a tribal entity highlights the involvement of Indigenous communities in environmental monitoring.

Escambia County, Alabama, is a rural area with a mix of forestry, agriculture, and light industry. Air quality monitoring is critical here to assess impacts from biomass burning, agricultural dust, and regional transport of pollutants. The station's location on tribal lands underscores the importance of monitoring in underserved communities, where data gaps often exist. Parameters measured typically include criteria pollutants and meteorological variables, with siting designed to capture representative conditions.
