Assessment of heavy metal contamination in surface water: A case study from Kanke Dam, Ranchi

Khusboo Kashyap & Arpana Sinha

ABSTRACT:

Surface water heavy metal concentrations must be tracked in order to assess environmental quality and possible health hazards. The current study measured the concentrations of a few chosen heavy metals in surface water taken from Ranchi, eastern India's Kanke Dam. Arsenic (As), lead (Pb), nickel (Ni), cadmium (Cd), and mercury (Hg) were measured in water samples using conventional analytical techniques in accordance with IS 3025. Pb was found at a low quantity of 0.002 mg L-¹, whereas As, Ni, Cd, and Hg were below the detection limit (<0.001 mg L-¹), according to the results. The acceptable limits set forth by IS 10500:2012 drinking water regulations were fulfilled by all measured heavy metals. The low quantities found point to little anthropogenic impact and show that there is now no major heavy metal contamination in the water body. In addition to highlighting the necessity of routine monitoring to identify longterm changes and possible buildup in sediments and aquatic animals, the study offers baseline data on heavy metal status.
