Abstract:
Background:Govi-Altai Province is located in an arid region of Mongolia with limited water resources, where the
main sources of drinking water are groundwater and springs. Therefore, regular assessment of water quality is essential
for protecting public health and ensuring sustainable management of water resources. The Mongolian Standard MNS
0900:2018 “Drinking Water. Hygienic Requirements, Quality and Safety Assessment” provides the theoretical basis for
this study and establishes criteria for evaluating physicochemical properties of drinking water. Previous studies reported
high hardness, mineralization, and heavy metal content in some soums, occasionally exceeding MNS limits, yet long-term
systematic studies are scarce. The study hypothesizes that “certain chemical parameters in drinking water of Govi-Altai
soums may exceed the maximum allowable standard limits.
Aim:To evaluate the physicochemical parameters of drinking water in the sums of Govi-Altai Province during 2019–
2024 and to assess hygienic risks by comparing the results with the MNS 0900:2018 standard
Material and Methods:This study analyzed 112 drinking water samples collected from 2019 to 2024. Major physicochemical
parameters were assessed and compared with MNS 0900:2018 standards.
Results:The average pH of the soums’ water was approximately 7.3, within the standard range. However, water hardness
was high in some soums (Bigēr 17.4 mg-eq/L, Tsogt 8.7 mg-eq/L), exceeding recommended levels. Nitrate reached up to
60 mg/L, fluoride 2.1 mg/L, and iron 0.9 mg/L, with some soums exceeding standard limits, indicating potential health
risks. Water from Yesonbulag soum complied with standard hardness limits, demonstrating variability in water quality
across the province. Comparison with studies from Inner Mongolia and Ulaanbaatar highlights differences in hardness,
mineral content, and heavy metal levels.
Conclusion:Physicochemical parameters in drinking water from some Govi-Altai soums exceed standard limits, and
high water hardness may pose public health risks.
