Abstrakt
The two-time groundwater sampling from domestic wells located in Dolni Studenky and Sudkov villages was realized for the impact specification of used de-icing chemicals. The increasing of conductivity and chlorides concentration was registered in groundwater after the winter road salting up to the distance 7–8 m from the roadside. As it was calculated from the amount of used de-icing material and rainfall, 23 % of chlorides were transported into the groundwater and no increasing of sodium concentrations was detected.

Klíčová slova:
groundwater; road de-icing; conductivity; sodium chloride
