Safe drinking water is a human need and right of the people. This study focuses on water quality analysis of the Urun-Islampur city which is in the Maharashtra state of India. Water quality testing is very important to check the quality of drinking water to avoid waterborne diseases and improve health. Water Quality Index (WQI) is important to determine the depletion of the water quality of the study area. The Urun-Islampur city is divided into fourteen wards. The values of WQI of those fourteen wards were compared, where from each ward three water samples were taken for the test. In order to assess the water quality, we calculate the WQI with physical, chemical and biological parameters. In water quality tests, various parameters are measured, including pH, total hardness, chloride content (Cl⁻), electric conductivity, residual chlorine and total dissolved solids (TDS), all those parameters compared with World Health Organization (WHO) standards of water quality; also in the present research paper classification of water samples of the 14 wards was an investigation into the basis of TDS, anions, cations, and total hardness. This article highlights the importance of using the WQI, and it is very useful to analyze the water quality. After water sample testing, it was observed that the pH of all water samples was found almost neutral. The TDS, conductance and hardness increased toward the old water supply line as compared to a new water supply line. The results of the Water Quality Assessment done in Urun-Islampur city show that all parameters were within the permissible limits as per WHO standards. The Water Quality Index (WQI) in the range of 86 to 90 was also good. But it may be affected by water distribution lines which were older than 30 years, so there is a need for proper maintenance of the distribution system and chlorination to avoid waterborne diseases.

印度马哈拉施特拉邦乌隆-伊斯兰普尔市的水质分析

安全的饮用水是人类的需求和人民的权利。这项研究的重点是位于印度马哈拉施特拉邦的Urun-Islampur市的水质分析。水质检测对于检查饮用水质量以避免水传播疾病和改善健康非常重要。水质指数（WQI）对于确定研究区域水质的耗竭至关重要。乌隆-伊斯兰浦市分为14个区。比较了这14个病房的WQI值，从每个病房取了三个水样进行测试。为了评估水质，我们使用物理，化学和生物学参数计算WQI。在水质测试，各种参数被测量，包括pH，总硬度，氯化物含量（CL ^-），电导率，残留氯和总溶解固体（TDS），所有这些参数均与世界卫生组织（WHO）的水质标准进行比较；在本研究的14个病房水样品分类中，还对TDS，阴离子，阳离子和总硬度进行了研究。本文强调了使用WQI的重要性，这对于分析水质非常有用。水样品测试后，观察到所有水样品的pH值几乎都是中性的。与新供水管线相比，旧供水管线的TDS，电导率和硬度增加。在乌隆-伊斯兰普尔市进行的水质评估结果表明，所有参数均在WHO标准规定的允许范围内。水质指数（WQI）在86到90之间。但是它可能会受到30年以上的水分配管线的影响，因此需要适当维护分配系统并进行氯化处理，以避免水生疾病。
