Abstract
Heavy metal contamination of drinking water poses a serious threat to
human health due to their toxicity, persistence, and bioaccumulative nature.
The present study evaluates the concentration of selected heavy metals—lead
(Pb), copper (Cu), nickel (Ni), iron (Fe), chromium (Cr), cadmium (Cd), and
zinc (Zn)—in drinking water collected from three different sites of the
Bisalpur Dam, Rajasthan, during summer, winter, and rainy seasons over the
period 2021–22 and 2022–23. Water samples were analyzed using Atomic Absorption
Spectroscopy (AAS) following standard procedures. The results revealed
noticeable seasonal and site-wise variations in heavy metal concentrations;
however, all analyzed metals were found to be within the permissible limits
prescribed by the World Health Organization (WHO) and Bureau of Indian
Standards (BIS). Higher concentrations of certain metals such as iron, nickel,
and zinc were observed during the rainy season, likely due to runoff and
sediment mixing. Overall, the findings indicate that the drinking water
supplied from the Bisalpur Dam is safe with respect to heavy metal
contamination, though continuous monitoring is recommended to ensure long-term
water quality sustainability.
