Groundwater level is measured daily in 74 wells with electronic sensors, 20 wells are equipped with telemetric level data transmission systems. Groundwater levels in a given area depend on meteorological and geological conditions. Shallow (up to 5 m) groundwater accumulating in clayey sediments, the level of which rises and falls by several meters during the year, is most likely to react to changes in meteorological conditions. In deeper water, the change in level is only a few centimeters.
