The article provides a comprehensive hygienic evaluation of drinking water quality in both existing andprospective domestic water supply systems of Samarkand. The research analyzes key hydrochemical andmicrobiological indicators, emphasizing the implications of anthropogenic and abiotic contaminants found inlocal water sources. The study utilized extensive analytical data derived from over 720 samples collected fromwells, clean water reservoirs (CWR), and the Zarafshan River, resulting in approximately 6480 laboratorydeterminations covering microbiological parameters, toxicological elements, organoleptic properties, andradioactive contaminants.Results indicate that the groundwater primarily serving Samarkand is generally safe,showing minimal microbial contamination and compliance with established hygienic standards. Groundwaterquality has remained consistently high, without significant anthropogenic pollutants detected. However, theassessment revealed a notable deficiency in fluoride concentrations (0.14-0.28 mg/L), raising concernsregarding increased risks of dental caries among the local population. Additionally, certain local water intakesdemonstrated increased hardness and mineralization levels due to natural geological processes, particularlynoticeable at the Bolibalandand Chupon-ota water intakes.The research highlights the necessity formaintaining rigorous sanitary protection measures, especially due to ongoing anthropogenic impacts such asagricultural activities and uncontrolled excavation operations near the water intakes. Furthermore, long-termdata analyses (1990-2024) suggest potential fluctuations in groundwater mineralization linked to climaticvariations and irrigation practices affecting the Zarafshan River's hydrological regime. Conclusively, thecurrent Samarkand water supply sources are robust and reliable, yet the establishment of additional waterintakes, especially near Chubot village on the Zarafshan River, is recommended. This strategic developmentcould significantly enhance the sanitary reliability and long-term sustainability of the city's water supplyinfrastructure, ensuring public health safety and improving overall water quality management.
