The objective of this study was to understand the drinking water quality state in the Inner Mongolia Autonomous Region from 2014 to 2018 and to derive information that will provide a basis for improving the drinking water quality in the region. Monitoring data for drinking water from the Inner Mongolia Autonomous Region for 2014 to 2018 were analyzed and the results were compared with GB 5749-2006, the Standard Test Method for Drinking Water, and GB 5749-2006, the Drinking Water Quality Standards. Data for a total of 30,613 water samples were assessed. Of the data for the microbiological index, sensory trait and general chemical index, and toxicological index, 89, 80, and 69% were qualified, respectively. For the toxicological index, the fluoride and nitrate nitrogen data were the least compliant. The water quality in all the cities was generally very suitable for drinking. However, there were marked differences in the qualified rates of drinking water in different areas and the qualified rates of the data for the three indexes were lower in rural areas than in urban areas. Given the varied issues with the drinking water quality, the relevant departments of League cities should implement appropriate and effective treatment measures to improve the drinking water quality and ensure it is safe for residents.

本研究旨在了解内蒙古自治区2014-2018年的饮用水水质状况，为改善该地区的饮用水水质提供依据。对内蒙古自治区2014-2018年饮用水监测数据进行分析，并与GB 5749-2006《饮用水标准试验方法》和GB 5749-2006《生活饮用水水质标准》进行对比。评估了总共 30,613 个水样的数据。微生物指标、感官性状和一般化学指标、毒理指标数据合格率分别为89%、80%和69%。对于毒理学指标，氟化物和硝酸盐氮数据的合规性最低。各城市的水质普遍非常适合饮用。但不同地区饮水合格率存在显着差异，三项指标数据合格率农村低于城镇。鉴于饮用水水质问题多变，各盟市有关部门要采取适当有效的治理措施，改善饮用水水质，确保居民生活安全。
