Well water quality in Drohobych territorial community
The article presents the results of the study on the quality of the well waters of the Drohobych
territorial community according to the following indicators: organoleptic indicators (smell, flavor,
color, pungency), nitrogen compounds content (ammonium ions, nitrites, nitrates), the content of
chlorides, sulfates, fluorides, total iron, calcium, the value of hardness, mineralization and pH. It was
found that the organoleptic parameters, in particular, the smell and taste of all test samples met the
standards. Exceeding the permissible values were detected for the color of well water in the villages
Rykhtychi (1.4 times), Dobrivlyany (2.1 times), Mykhailovychi (1.2 times), and turbidity - in the villages
Mykhailovychi (1.5 times) and Stupnytsia (2.1 times). It was studied that the content of nitrogen
compounds (ammonium, nitrites, and nitrates) in the analyzed samples did not exceed the MPC, but
there was a slight increase in ammonium compounds compared to the background values in the wells
of the villages of Rychtychi and Dobrivliana. It was found that the pH of the water was within the
normative values, except for the water of wells located in the village of Mykhailovychi, where the water
was somewhat acidified (pH = 6). Furthermore, it was found that the crystalline water of some
settlements in the study area (Lishnya village, Pochaevychi village, Rychtychi village, Luzhok village,
Mykhailovychi village) is quite hard 10 mmol/dm³. The content of chlorides, sulfates, and fluorides, as
well as mineralization in all water samples tested, were within the normative values. The exceedance
of the MPC regarding the content of total iron in the well water of the villages of Rykhtychi (1.2
times) and Dobrivliany (3.7 times) was investigated.
Keywords: Drohobych territorial community, water, drinking water, wells, ammonium ions,
