    Alright, well I’ll concede that my estimation of pH for battery acid was off - they have it listed at 0.8. I’m accurate with the AMD levels though.

    It can get very bad though, like the iron mountain mine article I linked to, where it’s -3.6

    With the lower pHs, though, even those around 5, you get metal leaching which quickly becomes a large problem. On top of that, the wastes act as a massive source of both acidity and metals.

      I agree. It is just not THAT acidic. The pH will be above 3.5 to be more specific, which is the pH above which Fe3+ can precipitate. Check this pallet for details.
