Abstract
Poor-quality drinking water can cause numerous health problems, particularly for people who are living with poor economic conditions, have a low educational status and have limited access to safe drinking water, such as the hill tribe people in Thailand. This study aimed to assess the quality of different sources of natural drinking water from the hill tribe villages in northern Thailand. Seventy-two drinking water samples from the hill tribe villages were collected and tested for biological, chemical and physical qualities, which were compared with the standard parameter values for safe drinking water according to the World Health Organization. Total coliform bacteria and fecal coliform bacteria, which represented the biological parameters, were detected in all samples. The physical parameters, which consisted of turbidity (36.1%), iron content (5.5%), color (2.7%) and pH (2.7%), exceeded the standard indications. However, the hazard quotient and hazard index values were less than 1. The hill tribe people are facing the problem of poor-quality drinking water, particularly in terms of biological and physical parameters that exceed the standard values. An effective program for improving access to safe water for the hill tribe people should be developed and implemented immediately.

泰国北部山区部落居民的饮用水源质量和健康状况
摘要
劣质饮用水会导致许多健康问题，特别是对于经济条件差、教育程度低且获得安全饮用水的机会有限的人，例如泰国的山地部落。本研究旨在评估泰国北部山区部落村庄不同来源的天然饮用水的质量。采集了来自山地部落村庄的 72 个饮用水样品，并对其进行了生物、化学和物理质量检测，并与世界卫生组织规定的安全饮用水标准参数值进行了比较。在所有样品中检测到代表生物学参数的总大肠菌群和粪大肠菌群。物理参数，包括浊度（36.1%），铁含量（5.5%）、颜色（2.7%）和pH值（2.7%）均超过标准指示。然而，危害商和危害指数值均小于1。山区部落人民面临着饮用水质量差的问题，特别是在生物和物理参数方面超过标准值。应立即制定和实施一项改善山区部落人民获得安全用水的有效计划。
