Abstract
Water safety planning is a comprehensive assessment and risk management approach that includes all stages of a drinking water supply chain, from the catchment to the consumer. A Water Safety Plan (WSP) ensures the safety of drinking water through this approach. In this study, risk factors were first identified and evaluated. In this research, the level of risks threatening the water supply sources of Imam Ali rural complex of Mashhad city was determined. A descriptive survey method based on the guide of the water safety program and the FMEA method of information analysis was implemented in which the required information was collected using the interview method, past records, a summary of experts' opinions, questionnaires and field visits. By calculating the RPN risk priority number, it was shown that water pollution due to the inflow of agricultural land effluent with a weight of 48.74 was the highest risk and the inflow of pollutants due to the lack of improvement of the wells with a weight of 19.25 was the lowest risk.
