The groundwater quality was evaluated using three indexing methods, the heavy metal pollution index (HPI), the heavy metal evaluation index (HMEI) and the contamination index (Cd). The levels of PTEs were calculated to determine the noncancer and cancer risks to the residents through ingestion and dermal adsorption. To obtain high-level accuracy in cancer risk estimation, a Monte Carlo simulation model and sensitivity analysis were performed. The mean values of PTEs in rainy and summer season were followed the order of Cr > Pb > Zn > Cu and Cr > Zn > Pb > Cu, respectively. The high level of Pb and Cr were exceeded the permissible limit of the World Health Organization (WHO) and Indonesian Standards. However, TDS, pH, EC and temperature were still in accordance with WHO guidelines. The geostatistical interpolation of HPI, HMEI and Cd revealed that the groundwater quality around Maros karst is low, particularly in Tukamasea and Leang-Leang village. Hazard index values were lower than one, implying no possibility of noncancer risk. The Monte Carlo simulation results with 95% confidence demonstrated children and adults are at risk for developing cancer due to PTE exposure. ## Keywords - Environmental science - Karst - Groundwater - Monte Carlo method - Risk assessment - Hazard quotient - Pollution - Index (typography) - Hydrology (agriculture) - Environmental health - Health risk - Statistics - Mathematics - Geography - Geology - Medicine - Computer science - Geotechnical engineering - Biology - Computer security - Ecology - Archaeology - World Wide Web --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
