摘要

本研究的目的是评价普度科泰地区Avudaiyarkoil区块的饮用和灌溉地下水质量，该区块是一个干旱易发地区。于2021年1月采集了20口井的样品，分析了水质参数，如pH、EC、TDS、Ca2+、Mg2+、Na+、K+、Cl-、HCO3、SO4、NO3和F-。分析结果表明，SO4为主要离子，其次为Cl-、HCO3-、Na+、Ca2+、Mg2+、K+、NO3-和F-，平均值为292>234>208.4>125>100>24.75>18>16.15>0.2。将分析结果与WHO和BIS指南值进行比较，了解地下水的可饮用性，并根据分析结果计算TH、TA、SAR、Na%、RSC、PI、MgC和KI，以确定地下水的灌溉适宜性。

Hydrogeochemical Evaluation of Groundwater for Drinking and Irrigation Purposes in Avudaiyarkoil Block, Pudukkottai District, Tamil Nadu, India

The purpose of this study is to evaluate the quality of groundwater for drinking and irrigation in the Avudaiyarkoil block of the Pudukottai district, which is a drought-prone region. Samples were collected from 20 wells on January 2021 and analysed for the water quality parameters, such as pH, EC, TDS, Ca2+, Mg2+, Na+, K+, Cl-, HCO3, SO4, NO3 and F-. The analysis revealed that SO4 is the dominant ion followed by Cl-, HCO3-, Na+, Ca2+, Mg2+, K+, NO3- and F- with respect to the mean value 292>234>208.4>125>100>24.75>18>16.15>0.2. The analytical results were compared with WHO and BIS guideline values to know the groundwater potability and TH, TA, SAR, Na%, RSC, PI, MgC and KI were calculated using the analytical results to identify the suitability of groundwater for irrigation purposes.

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
