My friend and I are science education majors and are preparing a lesson in the effects of acid mine drainage. We have found a site where there is a dicharge pipe into a stream. We ed upstream and downstream of the pipe. We expected the water downstream of the pipe to be relatively hard water. However, our test indicated that this was not the case. Both of us are aspiring biology teachers and the geology/chemistry of this area has us perplexed. Any insight you could give would be great! Thanks!
Re: Is the effluent from acid mine drainage 'hard' or 'soft' water?
