O článku:
We present the results of probably the first monitoring of isotopic composition of tap waters in Slovakia. The isotopic composition (δ18O, δ2H) of the tap water in two municipalities in the Jalovecký Creek catchment in northern Slovakia documented their different sources. The tap water in the Liptovský Mikuláš town (part Ondrašová) is on average isotopically similar to the Váh River water while the tap water in the Jalovec village is similar to the Jalovecký Creek. The temporal variability of the isotopic composition of both tap waters shows the contribution of the isotopically lighter snowmelt water. The consistently high electrical conductivity of the tap water in Jalovec suggests that the water comes from the Mesozoic rocks. The ground water in the alluvium of the Jalovecký Creek sampled in a borehole in Jalovec was isotopically similar to local tap water in summer and isotopically heavier in other seasons. The streamflow mean transit times were about a half of those of the tap waters and the borehole ground water (about 2 years versus about 1 year, respectively).
