ASSESSMENT OF GROUNDWATER QUALITY BY NITRATE ANIONS

This study is aimed at assessing the water quality based on nitrate concentrations in groundwater in Amudarya district and Kungirot district of the Republic of Karakalpakstan, Uzbekistan. The main objective is to analyze the quality of drinking water sources based on nitrate content. The research object is nitrate anions. The methodology includes collecting groundwater samples at a depth of 10-20 meters and analyzing nitrate concentrations following the GOST 33045-2014 standard. The results showed nitrate concentrations of 9.3 mg/l at station 1 and 16 mg/l at station 2 in 2022. In 2023, nitrate concentrations decreased at both stations. It is known that high nitrate concentrations in drinking water can lead to methemoglobinemia, cancer, and cardiovascular diseases, particularly in infants and elderly individuals. The novelty of this work includes recommendations aimed at introducing a permanent environmental monitoring system and improving drinking water quality, which is crucial for protecting public health.
