Impact of Water Table Fluctuations in Dug Wells on the Content of Nitrates in Water

Stanek-Tarkowska Jadwiga

Journal of Ecological Engineering

2022

Vol. 23, nr 6

22--29

The present study indicates the quick response of a shallow aquifer to precipitation. The nitrate content in water from 20 wells was determined. The study showed a significant 1-m decrease in the water table in the studied wells at low precipitation levels (10 mm) in April (wells 13 and 16). In turn, the water table in the wells after the maximum rainfall in September (130 mm) increased by 0.5 m in well 19. The results of the chemical analysis of the water indicate that the permissible nitrate content was highly exceeded in wells 3, 17, and 18. The nitrate content in wells 1 and 2 was almost 50 mg/l, which is the permissible value for drinking water. The precipitation level did not influence the content of nitrates in the well water.
