Dear Konstantin J Sylus, here are few links which will definitely help you in your research. Thanks and good luck

It depends on what you already know about kriging, for a good reference see "Geostatistics" by Chiles and Delfiner (J. Wiley) or the older "mining Geostatistics" by Journel and Huijbregts (Academic Press). In general see papers in Water Resources Research, Journal of Hydrology, Mathematical Geosciences, also see a book by G. De Marsily

Dear Konstantin, I am afraid you need a Kriging that interpolates in 3D. Unless you have an aquifer unit with a few meters thickness, depth needs to be given consideration. In other words, your analysis needs to be carried out not only in the horizontal plane but in the vertical one. As thickness increases so the importance of the Vertical components of flow.

The theory and the derivation of the kriging equations is not dimension dependent, it is true that some software packages are dimension restricted

If you want to see a practical example of structural analysis and kriging of groundwater quality data I suggest “Groundwater hydrochemistry of the Évora region of Portugal: geostatistical analysis” by Chambel and Almeida (1993) (you can download from researchgate).
