ABSTRACT

Groundwater quality is at high risk throughout the world including Sindh province in Pakistan. A sheer growth in global population, urbanization, mixing of sewage and industrial waste water with groundwater, and other unhygienic activities, are the main sources of groundwater contamination in almost all countries. This research is conducted for the evaluation of groundwater quality of Taluka Dokri based on the physicochemical parameters, and the obtained results revealed that 2.56% of the samples possessed color and odor beyond permissible limit, and about 23% samples were unsuitable for drinking purposes due to the salinity of groundwater samples. Overall, 30.77%, 38.46%, 30.77%, 41%, 100%, 38.46% of samples were unfit for the human consumption based on the high concentration of Ca, Mg, TH, TDS, EC, and Cl respectively. Additionally, results of the analysis of groundwater samples-based SPI approach concluded that around 10.3% of samples were slightly polluted, 66.67% samples were moderately polluted, and 23% samples were highly polluted. Overall, result showed that groundwater in UC Tatri, Baghi Bindi, and Wakro was slightly polluted; groundwater, in UC new Badah, old Badah, and Dokri was extremely polluted; and groundwater in remaining all union councils was moderately polluted, and in these UCs, water needed proper treatment before it is consumed by living beings.
