Abstract

Groundwater is widely recognized as an essential source of water for drinking and irrigation uses in the South India. It is essential to evaluate the characterization of groundwater for drinking and irrigation uses. A total of 67 samples were collected in different locations of study area from tube wells for physio-chemical analysis. Water quality index (WQI), nitrate pollution index (NPI), human health risk assessment (HHRA), and irrigation water quality index (IWQI) efficient tools have been used to evaluate the quality of groundwater in the present study. The Piper and Gibbs diagram revealed that weathering of parent rocks, evaporation, rock water interaction, and ion exchange process are influencing the nature of groundwater. The result of WQI showed that, 20.89% and 7.46% of the sample locations are moderate and poor quality of water for drinking purpose. In order to evaluate the nitrate contamination, NPI divulged that seven sample locations are significant very significant type of pollution. Based on HHRA, the children are at high risk compared to male and female in the study region. The higher percentage of the sample locations are suitable for irrigation uses. The study helps to identify the contaminated zones and also to follow emerging remedial measures to control the source of contamination in the region.

摘要

在南印度，地下水被广泛认为是饮用水和灌溉用水的重要水源。评估饮用水和灌溉用水的地下水特性至关重要。从试管井的研究区域的不同位置收集了总共67个样品，用于理化分析。在本研究中，水质指数（WQI），硝酸盐污染指数（NPI），人类健康风险评估（HHRA）和灌溉水质指数（IWQI）高效工具已用于评估地下水质量。Piper和Gibbs图表明，母岩的风化，蒸发，岩水相互作用和离子交换过程正在影响地下水的性质。WQI的结果显示为20.89％和7。46％的采样地点为中度且饮用水水质较差。为了评估硝酸盐污染，NPI透露七个样本位置是非常重要的非常重要的污染类型。基于HHRA，与研究区域的男性和女性相比，儿童处于高风险状态。较高百分比的样本位置适合灌溉用途。这项研究有助于识别受污染的地区，并采取新的补救措施来控制该地区的污染源。较高百分比的样本位置适合灌溉用途。这项研究有助于识别受污染的地区，并采取新的补救措施来控制该地区的污染源。较高百分比的样本位置适合灌溉用途。这项研究有助于识别受污染的地区，并采取新的补救措施来控制该地区的污染源。
