13 Investigates discovered Indiana's environmental watchdog agency allowed contamination to spread into neighborhoods at the same time it protected responsible companies from lawsuits. For decades, contaminated sites were allowed to sit untouched.
Across the state, we found contaminated water wells, asbestos in the air and toxic chemicals inching toward a city's water supply, and local officials didn't know.
State leaders first avoided questions but ultimately admitted they lost track of some sites and did not properly manage others. Now, a new program is in place and cleanup is moving forward under more strict guidelines.
