Abstract: Water contamination with toxic chemicals such as heavy metals continue to rise globally and particularly in developing countries due to mining, urbanization, and industrialization. In this study, a total of 10 stream water samples were collected from the mining environment. Physicochemical parameters such as pH and heavy metals; arsenic (As), chromium (Cr), nickel (Ni), and lead (Pb) were examined using standard procedures. The study assessed heavy metals concentrations, evaluated the pollution indices, and the health risk (carcinogenic and non-carcinogenic) for the populace (both adult and child) through direct oral intake and dermal contact of stream water in East Akim Municipal Assembly. The results of the concentrations of As (0.114 mg/kg), Cr (0.00000605 mg/kg), Ni (0.025 mg/kg), and Pb (0.257 mg/kg) revealed that they were within acceptable limits prescribed by World Health Organization (WHO) and Water guidelines. Heavy metal evaluation index (HEI) and degree of contamination (Cd) values obtained indicated that all the examined samples were categorized as low (Cd
