For the period 1906 to 1988, when Asse II was an operational salt mine, there were 29 documented water breaches.[27] They were sometimes successfully sealed off, partly dry or sometimes with negligible inflows (less than 0.5 cubic metres (130 US gal) per day).[28]
Between 1988 and 2008 32 new entry points were recorded. In 1996, the BFS notified the Bundesumweltministerium that there was a risk of severe radioactive contamination if the mine ran full of water and that further investigation was urgently required.

Hardly a long term solution.
