Dam Landfill Air Monitoring Station | Jefferson County, Ohio | USA Environmental Monitoring

Dam Landfill is an Air Monitoring Station located in Jefferson County, Ohio, United States. Operated by the Ohio EPA Southeast District Office, the station is part of the state's ambient air quality monitoring network, which supports compliance with the Clean Air Act and National Ambient Air Quality Standards (NAAQS). The facility is situated in a rural area near a landfill, reflecting typical siting for background or source-impact monitoring. The station's last reported sample date is December 31, 2020, indicating recent operational activity. While specific parameters measured are not detailed, Ohio EPA stations typically monitor criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead, along with meteorological parameters. The station contributes to the U.S. EPA's Air Quality System (AQS) database, which supports regulatory compliance and public health reporting. As part of Ohio's air monitoring network, Dam Landfill helps characterize air quality in the Ohio River Valley region, an area influenced by industrial activity, transportation, and coal-fired power plants. The data collected supports local air quality management, health advisories, and long-term trend analysis. The station's rural location provides valuable background measurements distinct from urban monitors.

The Ohio River Valley, where Dam Landfill is located, has a history of industrial emissions from manufacturing, power generation, and transportation. Air monitoring in this region is critical for assessing compliance with NAAQS and understanding regional pollutant transport. The station's siting near a landfill may capture fugitive emissions, while its rural setting offers baseline data. Parameter coverage typically includes criteria pollutants and meteorological variables, supporting both regulatory and research objectives.
