The present investigation reports the results of a monitoring study focusing on groundwater quality of Bhandara District of central India. Since, remediation of groundwater is very difficult, knowledge of the existing nature, magnitude, and sources of the various pollution loads is a prerequisite to assessing groundwater quality. The water quality index (WQI) value as a function of various physicochemical and bacteriological parameters was determined for groundwater obtained from a total of 21 locations. The WQI during pre-monsoon season varied from 68 to 83, while for post-monsoon, it was between 56 and 76. Significantly (P < 0.01) lower WQI for the post-monsoon season was observed, indicating deterioration of the groundwater overall in corresponding season. The study revealed that groundwater from only 19% locations was fit for domestic use, thus indicating the need of proper treatment before use.
本研究报告是对印度中部班德拉地区地下水质量监测研究结果的总结。由于地下水的修复非常困难，因此了解现有各种污染负荷的性质、程度和来源是评估地下水质量的前提。从总共 21 个地点采集地下水，根据各种物理化学和细菌学参数确定水质指数 (WQI) 值。在旱季，WQI 值在 68 到 83 之间变化，而在雨季，WQI 值在 56 到 76 之间变化。旱季的 WQI 值明显（P < 0.01）较低，表明相应季节地下水的整体质量恶化。研究表明，只有 19%的地点的地下水适合家庭使用，因此在使用前需要进行适当的处理。
