In order to analyze the water quality of groundwater drinking water sources in Hebei Province in recent years, taking 24 indexes of 42 groundwater drinking water sources in Hebei Province in 2000 and 2018 as the evaluation objects, the water quality situation and the contributing factors were analyzed using single index evaluation method and comprehensive evaluation method. The results showed that compared with 2000, the pollution level of 19 water quality indicators was reduced in 2018, fluoride pollution degree was serious, and four new water quality indicators exceeding the standard were added, The safe water sources creased by 11.9%, but the good water sources disappeared along with the extremely poor ones. In the protection area, the cultivated land area decreased and the forest land area increased, the construction land area increased, the agricultural pollution area decreased, and the industrial and domestic pollution areas increased. The pollutants mainly come from agricultural fertilizer, industrial wastewater and domestic waste, and groundwater overdraft will also affect the water quality. The research results can provide scientific guidance and practical support for the management and protection of groundwater drinking water sources in Hebei Province.
