The eastern hellbender is an endangered salamander found in the Blue River in southern Indiana. It requires cool, clean rivers and streams with high water quality in order to thrive. Water quality in the Blue River is affected by many factors. One relatively unknown contributor to poor water quality is pollution entering sinkholes. Many landowners have sinkholes on their properties and treat them like outdoor waste sites without knowing that these sinkholes have a direct link to our water supplies. In this video, Purdue biologists interview a local cave expert and a local conservationist about how sinkholes are connected to our rivers, streams, and water supplies and how we can help protect them.
