Water quality health and hazard risk assessment on Drinking Water Sources
A mathematical assessment method on water quality health and hazard risk in drinking water sources is established to calculate risk values caused by chemical carcinogens, radioactive pollutants, as well as non carcinogenic pollutants. And the assessment model is applied to analyze and assess the contaminated groundwater health status and hazard risk level. The results showed that the health risk values caused by chemical carcinogens are higher than the standard recommended maximum acceptable by the International Commission on Radiological Protection (ICRP), and far greater than the non carcinogen-induced Degree of risk. The ranking of risk values due to chemical carcinogen by drinking water is Cr+6>As>Cd, and the ranking of risk values due to non-carcinogen pollutants by drinking water is Pb>F->CN-> hydroxyl benzene>NH3-N. Chemical carcinogens are primary and should be removed possibly. The results also provide important information for groundwater quality management.
