of water in groundwater almost is horizontal, the groundwater of some districts
flows the pattern is very complicated.When the groundwater flows through to sink
to accumulate the rock, sink to accumulate rock is of big part can dissolve a
cent and will fuse the groundwater.Usually under circumstance, the cation that
dissolves to go into contain the Na ion, the calcium ion, the magnesium ion etc.,
