Abstract
This study investigated the heavy metals (HM) contamination in the water of Indus River and its tributaries, northern Pakistan. Water samples (n=44) were collected along with the five geological units: Kohistan batholith, Chilas complex, Kamila amphibolites, Jijal complex, and Indian plate. Observed HM levels were within the WHO drinking water guidelines except for Ni (23.7 µg/L) in the Jijal complex and Pb (10.6 µg/L) at on the Indian plate. Hazard quotient (HQ) values were observed < 1, suggesting no health risk through water consumption. Statistical analyses revealed that bedrock geology plays a major role in the HM distribution in water of the study area.
