Wilgus Air Monitoring Station, Lawrence County, Ohio | United States Environmental Monitoring

Wilgus is an air monitoring station located along S.R. 141 in Wilgus, Ohio, within Lawrence County. Operated by the Ohio EPA Central Office, it is part of the broader US EPA Air Quality System (AQS) network, which tracks criteria pollutants and other atmospheric parameters across the United States. The station's last reported sample date is September 30, 2025, indicating ongoing data collection. As a monitoring site in rural southeastern Ohio, Wilgus likely focuses on background air quality, capturing regional pollutant transport and local influences from nearby industrial or agricultural activities. The Ohio EPA manages a statewide network of monitors to comply with the Clean Air Act and National Ambient Air Quality Standards (NAAQS). Typical parameters at such stations include ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, though specific measurements at Wilgus are not detailed. The station's location in a non-urban setting provides valuable baseline data for understanding air quality trends away from direct urban emissions. This information supports regulatory compliance, public health advisories, and environmental research. Continuous operation ensures long-term datasets that help track improvements or deteriorations in regional air quality over time.

The Wilgus station monitors ambient air in a rural area of Ohio, where air quality can be influenced by regional transport from industrial centers in the Ohio River Valley and local sources such as agriculture and small manufacturing. The station's siting is representative of background conditions, providing critical data for assessing compliance with NAAQS and for studying long-term trends. Parameter coverage typically includes criteria pollutants, and reporting continuity is maintained through the Ohio EPA's network, supporting both regulatory and public information needs.
