Iowa Air Quality: Coal Plants Linked to Health Crisis

In 2025, the Iowa Environmental Council collaborated with Woodbury County residents to install air quality monitors. A year later, data revealed frequent acute air pollution events within the county. An analysis of local polluters identified fossil fuel combustion from coal-fired power plants, emissions from processing facilities, and vehicle exhaust as causes for concerning long-term exposure in the Siouxland region.

Exposure to PM2.5, a fine inhalable particle, is associated with adverse health outcomes such as respiratory illnesses, cardiovascular disease, strokes, and certain cancers. The report highlights a correlation between high PM2.5 levels and reported emissions from the George Neal North and South power plants, owned by MidAmerican Energy Company. The council advocates for a phaseout of these coal plants in favor of renewable energy sources.

While MidAmerican Energy acknowledges other factors influencing air quality, the Iowa Environmental Council's report emphasizes the significant role of coal emissions in elevating baseline PM2.5 levels. The council recommends expanding air quality monitoring, adopting electric vehicles, and investing in emissions controls and clean energy to mitigate health impacts.
