The purpose of the study is to find heavy metals in the groundwater in Manali, which is close to Chennai's Buckingham Canal. Heavy metal concentrations (As, Ba, Co, Cr, Ni, Cu, Pb, Zn) in water were examined to gain an understanding of the metal contamination caused by industrialization and urbanization surrounding the Manali Industrial region in Chennai, Southern India. This industrially advanced area is dominated by industries that produce hazardous waste, such as petrochemicals, fertilizers, and refineries. Six surface water samples and four groundwater samples were collected from Buckingham Canal and its environs throughout the monsoon and summer seasons of 2021–2022. An atomic absorption spectrophotometer was used to determine the amounts of the trace elements, which included zinc, nickel, lead, copper, and chromium. The resulting data were then contrasted with the standard values established by the World Health Organization (2008). Analysis of water samples from both sides of the canal reveals that proactive measures are required to lower the level of lead and nickel pollution.
