The health risk assessment of residents consuming groundwater with high arsenic concentrations has attracted widespread concern. This study therefore is aimed at providing a framework to evaluate the risks imposed to local residents of Simaria Patti Ojha village of Bhojpur district, Bihar. Results showed that the mean values of ADD, HQ and CR were 5.1 µg/(Kg Day) (PTDI- 2.1 µg/(Kg Day), 5-17 (safe range <1) and 0.002-0.007(tolerable range, 10^-6-10^-4), respectively. Carcinogenic risk value was found as 4.7 × 10^-3 around 100 times higher than safe range of 10⁻⁶–10⁻⁴, indicating high risks to the local residents. Hence, this study will help in suggesting suitable implementation measures on ground to deal with the risk of arsenic contamination and diseases caused due to its prolonged exposure.
