Our article presents the results of research aimed at determining the effect of precipitation on the level of the groundwater table and the impact of meteorological drought on the hydrogeological groundwater level in the area of Kujawy and Wielkopolska in the years 1981-2015. Monthly sums of precipitation came from Bydgoszcz and Poznan. Underground water table levels were measured by the Geological Institute in the area of Kujawy, near Bydgoszcz (Solec Kujawski and Jagodowo) and in the area of Wielkopolska (Stęszew and Czachurki).
