Overview
Southerly WWTP is an air monitoring station in Cuyahoga Heights, Ohio, operated under the CSN Supplemental network. It provides ambient air quality data for the Cleveland metropolitan area.
Southerly WWTP is an air monitoring station located at 6000 Canal Road in Cuyahoga Heights, Ohio, within Cuyahoga County. It is part of the CSN Supplemental network, which supports the US EPA's Air Quality System (AQS) by providing speciated particulate matter data. The station is operated by the University of California - Davis and has been actively reporting samples as of May 2025. The station operates under the regulatory framework of the US Clean Air Act, which mandates ambient air quality monitoring for criteria pollutants and air toxics. As a CSN Supplemental site, it focuses on chemical speciation of PM2.5, contributing to the national understanding of particulate matter composition and sources. The monitoring methodology follows EPA-approved reference or equivalent methods, ensuring data consistency with the broader AQS network. This station plays a key role in characterizing air quality in the Cleveland urban area, which is influenced by industrial emissions, transportation, and regional transport. The data collected supports health studies, regulatory compliance, and air quality management decisions. By providing long-term speciation data, Southerly WWTP helps track trends in particulate matter composition and the effectiveness of emission reduction strategies.
Environmental context
The Southerly WWTP air monitoring station is situated in Cuyahoga Heights, an industrial suburb of Cleveland, Ohio. The region has a history of heavy manufacturing and is subject to air quality challenges from industrial emissions, vehicle traffic, and lake-effect weather patterns. The station's focus on PM2.5 speciation is critical for identifying local pollution sources, such as steel mills and power plants, and for assessing the effectiveness of regional air quality management plans under the EPA's National Ambient Air Quality Standards (NAAQS).
