With a local volunteer organization, I witnessed the impact of acid mine drainage, seeping up from abandoned coal and clay mines, and poisoning local watersheds. In some of these streams, acidity levels (pH) can be comparable to that of soda and vinegar, creating an ecosystem where wildlife is unable to live or reproduce.
