Abstract

This study was carried out to find out the level of groundwater quality and composition in the ger area of Bayanzurkh district which is not connected to the water supply network. Fieldwork was carried out within the framework of the grant project on “Study of water quality in drinking water and economy of Ulaanbaatar city and development of recommendations to protect human health from water pollution” which was implemented in 2019 at our institute and the results of the study have been compiled and presented in this article. Samples were taken from 26 points in the 10th sub-district of the Bayanzurkh district and physicochemical parameters, microelements, and bacteriological analysis were performed to determine the chemical composition, quality, and pollution. According to the results of the water analysis, Ca-HCO3, Ca[HCO3-CI] and Ca-Mx were determined in the study area. As well total hardness (19.2%), Calcium (15.3%) and Magnesium (11.5%) are crosses the maximum permissible limits for human consumption as per the groundwater standards. According to the results of bacteriological analysis, 100 ml of Escherichia coli bacteria were detected in 100 ml of well water in the direction of Monel Altan Ulgii, Dari-Ekh, which is 15.4% of the total water point. 26.9% of the total water points have not met the requirements of drinking water standard MNS 0900:2018 and WHO recommendations in terms of total hardness, calcium, magnesium, and microbiological parameters. Water samples from private wells were found not meeting for human consumption and required treated and softened for drinking purpose.
