Allentown Air Monitoring Station | Pennsylvania Environmental Monitoring Facility

Allentown is an operational Air Monitoring Station located in Allentown, Pennsylvania, United States. It is situated at the State Hospital rear on Hanover Avenue and is part of the national air quality monitoring network overseen by the Pennsylvania Department of Environmental Protection. The station contributes to the US EPA's Air Quality System (AQS), which tracks criteria pollutants and other atmospheric parameters to ensure compliance with the Clean Air Act. The station operates under the regulatory framework of the US EPA, which mandates monitoring of pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. While specific parameters measured at this site are not detailed, typical stations in Pennsylvania's network include continuous analyzers for criteria pollutants and meteorological sensors. The station's last reported sample date is June 30, 2025, indicating ongoing data collection. Environmental monitoring in Allentown supports public health by tracking air quality in a region with mixed urban and industrial influences. Lehigh County's air quality is influenced by transportation, manufacturing, and power generation. Data from this station helps inform local air quality forecasts and regulatory decisions, contributing to community awareness and environmental management.

Allentown is located in the Lehigh Valley, a region with a mix of urban, suburban, and industrial land uses. Air quality monitoring here is critical due to emissions from transportation corridors, manufacturing facilities, and power plants. The station's siting at a state hospital provides a representative background location, though proximity to local sources may influence readings. Parameter coverage typically includes criteria pollutants, and reporting continuity is maintained through the Pennsylvania DEP's network, which supports compliance with National Ambient Air Quality Standards (NAAQS).
