ABSTRACT
This study is meant to assess the groundwater and surface water of Lashkergah City; in this study, drinking water pollution in terms of Heavy metal pollution index (HPI) and Correlation analysis performed. The water samples collected from five wells and one sample from surface water during the autumn season (October 2014). The concentration of metals like (Cr, Mn, Fe, Ni, Cu, Zn, Cd, Hg, Pb, and As) was tested and determined by Inductivity Coupled Plasma Mass Spectrometry (ICPMS). For analyzing the standard data methods, the HPI model, and resultant data utilized. Drinking water samples (n = 6), the highest value of heavy metal pollution index HPI = 96.82 has been recorded from the Lashkergah city area. Correlation analysis data showed that the sources of heavy metals in surface and groundwater analyzed between metals such as; Chromium positively correlated with Hg (r = 0.725801) and negative with other heavy metals. Mn has strongly positive correlation with Fe (r = 0.988553) and Arsenic (r = 0.909246), but some correlation with Nickle (r = 0.737467), Zinc (r = 0.664663) and Pb (r = 0.415797). And negative values with Cu, Cd, and Hg. A negative correlation means there is some difference between source amounts of metals. Still, a positive correlation shows that it obtained from the same amount of solid wastes and air pollutants in the study area. Wells and surface water metal-containing concentration is different, because surface water is directly contacted with wastes, air pollutants and used minerals than wells water, so it has less amount of heavy metals. Heavy metals like Cd, Hg, Pb, and As have bad impacts, and some of them are hazardous to all living things, especially to Human beings.
