PG Equestrian Center is an air monitoring station located at the PG County Equestrian Center in Greater Upper Marlboro, Prince George's County, Maryland, United States. It is part of the state's ambient air quality monitoring network, operated under the Maryland Department of the Environment. The station plays a role in the broader US EPA Air Quality System (AQS), which collects data on criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. The station operates within the regulatory framework of the Clean Air Act and EPA monitoring requirements. Air monitoring stations in Maryland typically measure a range of pollutants to assess compliance with National Ambient Air Quality Standards (NAAQS). The station's last reported sample date is October 31, 2025, indicating ongoing data collection. While specific parameters are not detailed, typical stations in this network monitor ozone, PM2.5, and meteorological conditions. Environmental monitoring at this site supports public health protection and regulatory compliance in the Washington-Baltimore metropolitan area. The data contributes to air quality index reporting, trend analysis, and policy decisions. The station's location near equestrian and recreational areas provides representative sampling for suburban and rural-influenced airsheds, complementing urban monitors in the region.
Environmental context
The station is situated in Prince George's County, a region with mixed urban, suburban, and agricultural land uses. Air quality in this area is influenced by emissions from transportation, power generation, and industrial sources in the Baltimore-Washington corridor. Monitoring at this site helps characterize ozone and particulate matter levels, which are of concern due to regional population density and regulatory non-attainment areas. The station's data supports the EPA's AQS network and informs local air quality management strategies.
