Water pollution is one of the most dangerous problems which is commonly ignored in our country. Pakistan ranks very low in the world, regarding drinkable water. Both surface and underground water are contaminated with toxic metals and pesticides and arsenic (μg/L) were found to be 50. The quality parameters set by the WHO are persistently violated. The water quality is seriously affected by improper disposal of industrial, domestic waste and agrochemicals. These pollutants are responsible alone, or along with other factors for a variety of health problems. This article discusses drinking water being supplied in Sahiwal (Pakistan) to students living in the hostel along with an emphasis on the major pollutants, their effects and consequent health problems. The data presented in this article have been collected in Sahiwal. The water samples were collected from the main supply and the blood samples were of the consumers of that water.

水污染是我国普遍忽视的最危险的问题之一。在饮用水方面，巴基斯坦在世界上排名非常低。地表水和地下水都被有毒金属和杀虫剂污染，发现砷 (μg/L) 为 50。世界卫生组织设定的质量参数不断被违反。工业、生活垃圾和农用化学品处置不当，严重影响了水质。这些污染物单独或与其他因素一起导致各种健康问题。本文讨论了在萨希瓦尔（巴基斯坦）为住在宿舍的学生提供的饮用水，并重点介绍了主要污染物、它们的影响和随之而来的健康问题。本文中提供的数据是在 Sahiwal 收集的。
