New Castle Air Monitoring Station, New Castle, Pennsylvania | Environmental Monitoring

New Castle is an air monitoring station located at Croton St & Jefferson St in New Castle, Pennsylvania, United States. Operated by the Pennsylvania Department of Environmental Protection, this facility is part of the state's ambient air quality monitoring network, which supports compliance with the US EPA's National Ambient Air Quality Standards (NAAQS). The station collects data on criteria pollutants to assess regional air quality and protect public health. The station operates under the regulatory framework of the US EPA's Air Quality System (AQS), which standardizes monitoring methods and data reporting across the country. While specific parameters measured are not detailed, typical air monitoring stations in Pennsylvania track pollutants such as ozone, particulate matter (PM2.5 and PM10), sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead. The station's location in an urban setting ensures representative sampling of population exposure. As part of the Pennsylvania DEP's network, New Castle contributes to long-term air quality trends and informs local environmental management decisions. The data supports public health advisories, emission reduction strategies, and compliance with federal standards. The station's operational status and recent sampling activity (last sample January 2024) indicate ongoing monitoring efforts in the region.

New Castle is situated in Lawrence County, Pennsylvania, within the Ohio River Valley region, which has a history of industrial activity including steel manufacturing and coal-fired power generation. This industrial legacy contributes to elevated levels of particulate matter and ozone precursors. The monitoring station's location in an urban area helps capture population exposure to these pollutants. Data from this station supports the EPA's regulatory programs and helps track progress toward meeting NAAQS, particularly for ozone and PM2.5, which are regional concerns.
