“…Results indicated that the metals' contamination factor (CF) such as Zn, Cu, Cr, and Ni in the study area is less than one. Whereas CF values of Fe and Pb are higher than one, it indicates that groundwater of the study area is contaminated concerning these metal ions, perhaps due to the influence of industrial activity and anthropogenic sources [29,30]. The PLI values of all the sampling locations of the study area were found to be generally low (<1).…”

Freshwater consumption has been increased because of population growth and economic development. At the same time, depletion and contamination of groundwater is subject of great concern. Karachi is the industrial hub and serves as the economic backbone of Pakistan. The research aims to investigate the heavy metal pollution in the groundwater of Korangi Industrial Area, one of the largest industrial estates in Karachi. Eighteen representative locations were selected to collect groundwater samples and study the concentrations of heavy metals Cr, Fe, Ni, Cu, Zn, and Pb. Pollution load index, Nemerow's pollution index, and geo accumulation index approaches were used to interpret the basic data. The average concentrations of the measured heavy metals were 354.67 µg.L-1 , 694.33 µg.L-1 , 39.2 µg.L-1 , 12.89 µg.L-1 , 9.5 µg.L-1 , and 6.17 µg.L-1 for Fe, Zn, Cu, Pb, Cr, and Ni, respectively. The results showed that groundwater quality in the study area is poor and mainly contaminated by Pb and Fe.
