Coming up later we look back at a feature report from September 2020 when federal officials filed a lawsuit against Indianapolis Power and Light claiming that the company has been violating the Clean Air Act repeatedly. According to the IndyStar, the coal-fired power plant agreed to reduce its emissions, “on behalf of the state of Indiana and its environmental management agency.”
Environmental ReportsOzone Pollution on the RiseNearly 152.3 million Americans live in areas with unhealthy air pollution, primarily from ozone and PM2.5 particles, according to the American Lung Association’s 2026 “State of the Air” report. Over 129 million reside in counties with failing ozone pollution grades, a result of emissions from vehicles, industries, and chemicals that generate ground-level ozone. Approximately 62 million people experience daily spikes in particle pollution from sources like car exhaust and construction.
The report highlights significant disparities in exposure, with people of color more than twice as likely to live in regions with failing pollution measures, often linked to socioeconomic resources that limit access to healthy food, safe exercise areas, and healthcare. Contaminated air adversely impacts not just health but also family dynamics and financial conditions. Children are particularly vulnerable, with 33.5 million living in counties failing to meet standards for at least one major pollutant, which can result in reduced lung development and lower lung capacity later in life.
Despite progress under the Clean Air Act since 1970, air pollution is worsening due to climate change, which exacerbates conditions like extreme heat and wildfires. Particle pollution, while slightly improved, still affects many more people than in prior years. The American Lung Association advises residents in polluted areas to limit outdoor activity, use N95 masks, and maintain clean indoor air. Staying current on vaccines, including for flu and COVID, can provide additional health protection. Emphasizing community action, it is essential to sustain advancements in air quality through robust public health policies, as clean air efforts in one area benefit all. “Air does not respect borders,” Dr. El-Hasan states, underscoring the importance of localized efforts in promoting national air quality.
Indiana Ranks Poorly in PollutionIndiana ranks as one of the most polluted states in the U.S., with U.S. News & World Report designating it as the worst state for pollution and natural environment in 2025. The state’s performance in industrial toxins and pollution-related health risks places it 48th in both categories. In statewide air quality rankings, Indiana is often among the top three most polluted states, with the Indianapolis-Carmel-Muncie area ranked 11th for year-round particle pollution in the American Lung Association’s reports from 2025 and 2026. Marion and Lake counties frequently receive failing grades for ozone and particle pollution.
The primary sources of pollution include emissions from factories, steel mills, and refineries, particularly in Northwest Indiana, where coal-fired power plants are significant contributors to smog and soot. Transportation, due to heavy diesel truck traffic and passenger vehicle emissions, accounts for 60% to 70% of nitrogen dioxide levels in some areas. Additionally, natural factors such as wildfires and high ozone levels from decaying forest matter occasionally exacerbate pollution.
While the Indiana Department of Environmental Management (IDEM) notes a 74% reduction in statewide air contaminants over the last 25 years, concerns arise from recent budget cuts and the rollback of stricter environmental regulations.
Monroe County to Restore Prairie GrasslandThe Monroe County Board of Commissioners convened on May 7th to discuss and approve a partnership agreement with the U.S. Fish and Wildlife Service aimed at a prairie restoration project at the Monroe County Nature Preserve. This undertaking will revitalize approximately 24 acres of prairie grassland habitat through a collaborative effort involving Monroe County Parks, the Indiana Department of Natural Resources, and federal wildlife officials. Parks Director Kelli Witmer highlighted that the initiative aims to link fragmented prairie areas into a unified habitat conducive to wildlife. Commissioner Jody Madeira expressed support for the initiative, leading to the commissioners approving the measure with a 3-0 vote. The next meeting is scheduled for May 14th.
And now for some upcoming events:* A Let’s Propogate an Herb Garden class is scheduled for Thursday, May 14th, from 6 to 8 pm at the Butler Community Gardens. After the class, you will get to take home a miniature herb garden to start the season. Register at bloomington.in.gov/parks.
Are you looking for a way to make a difference on environmental issues?Eco Report is looking for reporters, engineers, and segment producer to report facts on how we’re all affected by global climate disruption and the ongoing assaults on our air, land and water. We also celebrate ecologists, tree huggers, soil builders and other champions who actively protect and restore our natural world, particularly those who are active in south central Indiana. All levels of experience and all ages are welcome, and we provide the training you’ll need. WFHB also offers internships.
