АНАЛІЗ ФІЗИКО-ХІМІЧНИХ ПОКАЗНИКІВ ПИТНОЇ ВОДИ З КОЛОДЯЗІВ У СЕЛИЩАХ КОМАРІВКА ТА ПІДЛИМАН ХАРКІВСЬКОЇ ОБЛАСТІ

Abstract

A comparative analysis of the physicochemical parameters of drinking water from wells in the settlements of Komarivka and Pidlyman, Kharkiv region, was conducted in September 2025. The following parameters were investigated: total hardness, pH, total dissolved solids, concentrations of chlorides, sulfates, iron, ammonium, nitrates, nitrites, and electrical conductivity. Exceedances of the standard values were identified for the following indicators: total hardness (18.72 mmol/dm3 in Komarivka and 11.52 mmol/dm3 in Pidlyman), mineralization (1670 mg/dm3/ppm and 1134 mg/dm3/ppm, respectively), and electrical conductivity. No exceedances were detected for nitrates, nitrites, ammonium, sulfates, chlorides, or iron in the analyzed samples. According to the classification of DSTU 4808:2007, the water in Komarivka is classified as Class IV (poor quality) based on indicators such as color, mineralization, total hardness, and ammonium content. In Pidlyman, indicators such as odor and total hardness fall into Class IV, while mineralization, ammonium content, and pH correspond to Classes III and II of water quality. The results indicate limited suitability of the drinking water for consumption by the local population without prior treatment and confirm the need for implementing purification measures and continuous monitoring of water quality in frontline regions.
