Overview
LORING AFB SOG SSITE, NEAR SQUA PAN is an air monitoring station in Aroostook County, Maine, operated under the US EPA National Exposure Research Lab. It is part of the national network tracking criteria pollutants and air quality trends.
LORING AFB SOG SSITE, NEAR SQUA PAN is an air monitoring station located at the former Loring Air Force Base in Aroostook County, Maine. The station is part of the US EPA's National Exposure Research Lab network, contributing to the Air Quality System (AQS) that monitors ambient air pollution across the United States. Its rural location provides baseline air quality data away from major urban emission sources. The station operates under the US EPA's regulatory framework, which includes monitoring criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. As part of the AQS network, it follows standardized siting and measurement protocols to ensure data representativeness and comparability. The station's remote setting in northern Maine helps characterize regional background air quality and long-range transport of pollutants. Environmental monitoring at this site supports the Clean Air Act's objectives by providing data for air quality assessments, trend analysis, and health studies. The station's location near the Canadian border also contributes to understanding transboundary air pollution. Its continuous operation helps track changes in air quality over time, informing regulatory decisions and public health advisories.
Environmental context
The station is situated in a rural area of Aroostook County, Maine, characterized by forests and agricultural land. This setting is important for monitoring background air quality and long-range transport of pollutants from industrial and urban sources. The site's data helps assess the effectiveness of emission reduction programs and supports the US EPA's National Ambient Air Quality Standards (NAAQS) compliance tracking. Its location near the Canadian border also provides insights into transboundary air pollution dynamics.
