great post ewest. i'm glad someone w/ "east coast" expertise chimed in. kaolin could explain alot of things including the high conductivity, but low alkalinity values greg posted up top. can you elaborate more on this ewest?
i am a bit surprised at the eye irritation part, kaolin dust would cause eye irritation, but greg said the water is clear, so unless it was suspended particles somehow, i dont get that part unless its simply the pH.
greg, i hope you see this before you scare the owner w/ my post, it may be as simple as a kaolin pit and not "hard rock" acid mine leach. rock type and site history will undoubtedly tell the story.
