Coffeeville Air Monitoring Station | CASTNET Site in Mississippi, USA

Coffeeville is an air monitoring station located at the Jamie L. Whitten Plant Materials Center in Coffeeville, Mississippi, United States. It operates under the Clean Air Status and Trends Network (CASTNET), a national program designed to monitor ambient air quality and deposition. The station is part of a network that provides critical data on pollutants such as ozone, sulfur dioxide, and nitrogen compounds, supporting regulatory compliance and scientific research. The station is operated by Mactec, Inc, and reports data to the U.S. Environmental Protection Agency (EPA). CASTNET stations follow rigorous siting and quality assurance protocols to ensure representativeness and data continuity. The monitoring typically includes criteria pollutants, meteorological parameters, and speciated measurements, contributing to the EPA's Air Quality System (AQS) database. Located in a rural agricultural area, Coffeeville monitors background air quality in the Mississippi Delta region. Its data helps assess the impact of regional emissions from agriculture, industry, and transportation. The station's long-term record supports trend analysis and policy evaluation under the Clean Air Act, providing valuable information for environmental management and public health protection.

The Coffeeville station is situated in a rural agricultural region of Mississippi, where air quality is influenced by farming activities, including pesticide application and biomass burning, as well as long-range transport of pollutants. CASTNET's focus on rural and remote sites provides baseline data essential for understanding regional air quality and deposition patterns. The station's parameter coverage includes criteria pollutants and meteorological variables, enabling assessment of ecosystem effects such as acidification and eutrophication.
