Ohio's rich coal mining history casts a long shadow. Abandoned mines leak acid mine drainage (AMD) - water laced with harmful metals and iron oxides. This acidic runoff pollutes streams, turning them orange and wiping out aquatic life. It's a major threat to the state's water quality. Thankfully, efforts are underway to identify AMD sources and implement treatment solutions. By tackling this legacy issue, Ohio can heal its waterways and ensure a healthier future for its ecosystems.
