Water pollution has become more serious due to the rapid development of urbanisation and information technology in China and the rapid growth of the social economy. Water quality safety has become a major challenge in the world today and water pollution control is urgent. In recent years, urban groundwater contamination has been a frequent occurrence, and water safety has received key attention. Water quality assessment is an important task to ensure safe water for urban residents. Studying and assessing the risk of contamination at major water sources is key to solving major water pollution incidents. In this paper, the improved analytic hierarchy process is used to establish the risk assessment model of groundwater pollution (GWP) accidents, analyze the GWP situation in M city, and obtain that the risk of COD and ammonia nitrogen pollution in groundwater in M city has an increasing trend. In order to prevent and control water pollution in M City, suggestions on pollution source risk management and control and groundwater quality monitoring are put forward.
