A420950100LAT/LONG POINT IS OF SAMPLING INLET - Easton, Pennsylvania Air Monitoring Station

A420950100LAT/LONG POINT IS OF SAMPLING INLET is an air monitoring station located at the intersection of Coal Street and Milton Street in Easton, Pennsylvania, United States. The station is part of the state-level ambient air quality monitoring network operated by the Pennsylvania Department of Environmental Protection. It contributes to the national Air Quality System (AQS) managed by the US Environmental Protection Agency. The station operates under the regulatory framework of the Clean Air Act and the National Ambient Air Quality Standards (NAAQS). As a monitoring site in the mid-Atlantic region, it typically measures criteria pollutants such as ozone, particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead. The exact parameter set is determined by the state implementation plan and may include meteorological parameters to support air quality modeling. This station serves the Easton metropolitan area and the Lehigh Valley region, providing critical data for public health advisories and regulatory compliance. Its location near industrial and transportation corridors helps assess local air quality impacts. The data collected supports the development of air quality management strategies and informs the public about environmental conditions.

The Easton area lies within the Lehigh Valley, a region with a mix of industrial, commercial, and residential land uses. Air quality monitoring here is important due to proximity to major highways and industrial facilities. The station's siting is representative of urban background conditions, capturing pollution from both local sources and regional transport. Parameter coverage typically includes criteria pollutants, with possible speciation for PM2.5 and ozone precursors, supporting the state's compliance with NAAQS.
