By the beginning of January 2003, the lysimeter was completely equipped with a UMS environmental monitoring system – the recording and sampling system. 15 tensiometers, 9 Time Domain Reflectometry (TDR) probes and 21 suction cups were installed into the boreholes, as listed in Table 1.

2003, Apr. and Jun. 2004). Statistical characteristics of the electro-conductivity of sampled water are presented in the form of boxplots ranges from 180 to 615 ␮S/cm (Figure 6). Significantly higher values were recorded on the left side of the lysimeter – up to 4000 ␮S/cm. These most probably result from winter contamination. Lowest electro-conductivity values in the lysimeter are connected with levels I and II (Figures 6 and 7), whereas highest values are connected with level III (Figures 6 and 7), which reflects the important role of the lateral flow component near this level.
