- Abstract
It is indispensable to examine heavy metals in water resources due to their incorporation in the food chain, hence the possibility of harmful impact on human health. In this study, degree of heavy metal contamination is investigated in the Himalayan surface and spring water systems of the Kulgam district, India. This study examines 16 heavy metals which include V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Rb, Sr, Zr, Mo, Ba, and Pb. Among the analyzed parameters, Pb (100%, n = 30) and Fe (13.3%, n = 4) in springs was found above the desirable limits of drinking water. The heavy metal pollution index (HPI) results demonstrated that both the surface and spring water resources are at high-risk zone with HPI > 100. Based on the degree of contamination (Cd), surface and spring water system falls in the medium and high-risk zones. The results of health risk evaluation based on deterministic and Monte Carlo simulation (MCS) showed hazard index (HI) > 1 and the probability of total cancer risk (TCR) for adults and children in both the water systems was found above the U.S Environmental Protection Agency (USEPA) threshold value of 1.0E-04. Principal component analysis (PCA) estimated origin of heavy metals, and results showed that natural geogenic processes such as rock–water interaction or mineral dissolution and anthropogenic activities are responsible for heavy metal concentration in the surface and spring water systems.
