Underground springs and wells are the water supply for residential buildings in the region. Monitoring studies of the physicochemical composition of drinking water from underground sources, wells and wells is necessary, because in the selected region we studied drinking water samples for nitrates, nitrites, phosphates, ammonium, determined total mineralization and determined pH, analyzed the results and based on them, conclusions were drawn about the impact of seasonal changes on groundwater supply.</p><p>Seasonal changes are clearly expressed in the NNP during the observation period September-November during the low tide and April-May during the minor floods of 2021. We observe an increase in the content of nitrates and fluctuations in the content of phosphates and ammonium, in some studied water samples, nitrate levels are much higher in the limited period than floods. There are deviations from the norm of pH of several tested samples and low total mineralization of water from natural sources, which may have a negative impact on human health with long-term consumption.</p><p>Possible factors of influence of decentralized drainage and anthropogenic load of tourist establishments on the potential increase of groundwater pollution are given, it is established that seasonal fluctuations occur primarily due to changes in the main food sources and denitrification processes.</p> ER -
