    Water hazard in the Wieliczka mine is associated with sandy formations of the Chodenice layers existing on the northern side of the salt deposit. In history, all water penetrations of the mine originated at these formations. Quite less dangerous are spills from Quaternary and sub-salt deposits, technological brines (most spills on level VI) and leaks. Since 1993 liquidation works are performed in the central area of the mine targeted at achieving orogen stabilisation and securing the mine from new sudden inflows. Since 1999, gradual liquidation of leaks has been carried out, with simultaneous monitoring of their expenses, chemistry and conducting isotope research.
