Shivnath River in Chhattisgarh State is considered as Life line of Chhattisgarh, which covers about 290 km. Three different location were selected for study, first area Piperchhery, second Mahamarra Ghat, and third Changory. This study investigates the spatial distribution, seasonal variations, and potential human health risks of heavy metal contamination in the water of the Shivnath River, Chhattisgarh. Water samples were collected across three seasons from three strategically selected sites reflecting different anthropogenic pressures: Piperchhedy, Mahamara Ghat, and Changory. The concentrations of key toxic metals, including Lead (Pb), Iron (Fe), cadmium (Cd) and Hg (mercury), were analyzed using Atomic Absorption Spectroscopy (AAS). Environmental indices, such as the Heavy Metal Pollution Index (HPI), were computed to quantify overall water quality. Human health risk was evaluated via the Hazard Quotient (HQ) and Carcinogenic Risk (CR) for both adults and children through oral ingestion and dermal pathways. The results revealed significant spatial variation; Mahamara Ghat exhibited elevated levels of specific metals during post-monsoon and festival seasons due to high anthropogenic and religious activities, while Piperchhedy and Changory showed distinct profiles influenced by agricultural runoff and downstream accumulation. The study underscores the critical need for localized monitoring at these specific ghats and zones to safeguard public health and riverine ecology. To maintain the healthy ecosystem of the river, proper management and monitoring of water quality of the river is needed.
