The following criteria were used to assess the quantitative status of groundwater
bodies:
– water balance;
– connection with surface water;
– influence on groundwater ecosystems dependent on groundwater;
– intrusion of saline water or other intrusions.
The freatic pollution is often an almost irreversible phenomenon, with significant
consequences on the use of the underground water supply for drinking purposes, and
the de-pollution of groundwater sources is a very difficult process (Figs. 3.36, 3.37
and 3.38).
The groundwater bodies are characterized by the slow response (unsaturated zone,
recharge process, aquifer conditions, underground flow conditions, in part merely
characteristic for a flow line), the hydrodynamic situation being essential for monitoring actions due to the long time period from recharge to discharge (Figs. 3.39 and
3.40).
Groundwater quality monitoring revealed that in 2016, about 16% (23/143) underground water bodies were outside the chemical parameters imposed by the rules. In
2016 there were reported 47 accidental pollution, the distribution of which according to the nature of the pollutant is as follows: untreated wastewater 18 (events)—
accounting for 38.30% of the total accidents; petroleum products 14 events—29.79%;
