While doing research on rivers online, I read an article about how tributaries of the Lackawanna and Susquehanna Rivers have both been damaged by acid from abandoned mine projects. Holes dug in the tributaries create water up flow that stains the water and rocks touching it. I thought this was an interesting subject and I didn’t know that this problem was so big in Pennsylvania.
That’s very interesting – I am surprised that there hasn’t been much more talk about this, given that there has a large push for repairing ecological damage. Also had no idea that this could be a problem in general.
