Indiana Toxicity Watch (ITW) is a statewide initiative by Indiana University that makes environmental data easy to find, understand, and act on. The platform brings together information from multiple state and federal sources including the EPA, IDEM, and Indiana Finance Authority into one open, public-access hub. It helps policymakers, researchers, and residents visualize pollution trends, site details, and cleanup progress across all 92 Indiana counties.
The need for clear, accessible environmental data has never been greater. Recent reports highlight the scale of the challenge our state faces:
50Indiana ranked as the worst state for pollution & natural environment. (U.S. News & World Report)
17%of Indiana residents live near toxic release facilities. (EPA Toxic Release Inventory)
FMarion County's air quality grade, failing on all measured pollutants. (American Lung Association)
To make Indiana’s environmental information transparent, accessible, and actionable — empowering every citizen to understand and engage with the state’s ecological health.
